GENERAL INFORMATION AND

IMPORTANT OPERATING FACTS

This manual has been compiled to aid in the installation, opera-

tion and maintenance of your equipment. Please read it and

familiarize yourself with your equipment, its operation and avail-

able accessories, to enjoy optimum performance.

This equipment is prohibited from use in California with

any refrigerants on the “List of Prohibited Substances” for

that specific end-use, in accordance with California Code of

Regulations, title 17, section 95374. This disclosure statement

has been reviewed and approved by NRAC, Inc. and NRAC, Inc.

attests, under penalty of perjury, that these statements are true

and accurate.

SERIAL DATA TAG

A serialized data tag is permanently attached to the inside right-

hand wall of your unit. (see Figure 1). In addition to identifying

the specific product, this label provides important information

regarding electrical requirements and refrigeration charge, as

well as agency listings and factory contacts.

REACH-INS & ROLL-INS

OPERATIONS MANUAL

Standard Reach-In refrigerators and freezers have an internal

evaporator coil located behind the fan panel on the inside ceil-

ing of the refrigerated compartment (see Figure 2). Designer

Line Reach-In, as well as all Pass-Thru, Roll-In and Roll-Thru

refrigerators and freezers have an insulated housing located on

top of the cabinet, that contains the evaporator coil, out of the

refrigerated storage area (see Figure 2A & 2B).

All warmers have an insulated housing located on top of the

unit, that contains a blower fan to circulate warm air inside the

cabinet (see Figure 2C). On most models, the high-wattage,

finned electric heating elements are located inside the cabinet,

at the bottom of the interior side walls. On single-section Roll-In

and Roll-Thru models, the heating elements are located in the

housing on top of the unit, to optimize space for carts inside

the cabinet.

FIGURE 2A: Designer Line Reach-In or Pass-Thru

Refrigerator or Freezer

FIGURE 2: Standard Reach-In Refrigerator or Freezer

Four (4) bolts secure the cabinet to the wooden skid. The bolts

are located at each end on the underside of the skid. In order to

remove these bolts, tilt the cabinet backwards and place wood-

en blocks at each end in order to hold it in its tilted position.

Using a ¾” socket or open end wrench, remove the bolts and

carefully slide the cabinet off of the skid. If caster support plates

are to be installed, save the bolts and washers (see “Mounting

Caster Support Plates” under “Optional Accessories”).

After skid removal, the cabinet should never be moved without

dollies or rollers to avoid damage to the cabinet bottom or floor.

IMPORTANT NOTE: Do not under any circumstances, lay

your new model on its front or sides. For a brief period

of time, you may lay the cabinet on its back, but only

when it’s properly blocked so as not to crush the back

or end panels and also to allow provision for your hands,

in order to set it in its upright position without damaging

the cabinet. Do not plug in and operate model for at

least three (3) hours after cabinet is set upright from

being on its back as this can damage the compressor.

MODEL COMPONENTS

OPERATIONS MANUAL

REACH-INS & ROLL-INS

Before moving the cabinet to its final point of installation, mea-

sure all doorways or passages to assure clearance. If additional

clearance is needed, you can remove the cabinet doors and grill

(see “Door Removal and Adjustment” and “Grill Removal”).

IMPORTANT NOTE: COMPONENT PARTS SHALL BE REPLACED WITH LIKE

COMPONENTS AND SERVICING SHALL BE DONE BY AUTHORIZED SERVICE

PERSONNEL TO REDUCE THE POSSIBLE RISK OF IGNITION.

IMPORTANT NOTE: THE APPLIANCE IS TO BE INSTALLED IN ACCORDANCE

WITH THE SAFETY STANDARD FOR REFRIGERATION SYSTEMS, ANSI/

ASHRAE 15. REFER TO THE DATA TAG FOR REFRIGERANT AMOUNT. IF THE

APPLIANCE HAS A REFRIGERANT CHARGE OF MORE THAN 114 GRAMS, THE

APPLIANCE SHALL NOT BE INSTALLED IN PUBLIC CORRIDORS OR LOBBIES

VENTILATION

The final location site of your air cooled refrigerator or freezer

must provide a sufficient quantity of cool, clean air. All refrigera-

tion systems operate more efficiently and trouble-free with cool,

dry air circulation. Avoid locations near heat and moisture gen-

erating equipment including ovens, fryers, dishwashers, steam

kettles, etc. Do not install in direct sunlight (where temperatures

FIGURE 2B: Roll-In or Roll-Thru Refrigerator or Freezer

INSTALLATION AND LOCATION

FIGURE 2C: Reach-In or Pass-Thru Warmer

may exceed 100°F) or in an unheated area (where temperatures

may drop below 55°F).

Air supply to the condensing unit is critical. Restricting airflow

places excessive heat load on the unit, adversely affecting its

operation and may cause premature failure. The condenser coil

must be kept clean and free from obstruction. Condenser air fil-

ters are not recommended, since they hinder airflow, especially

if they are not replaced frequently. Contact our factory Service

Department for more information.

For optimum performance, all models should be installed on

casters or legs (see “Installing Casters” or “Legs”) with a

minimum 12” above the grill and 3” on each side and back of

cabinet (see Figure 3). This spacing will provide sufficient room

for proper air circulation and clearance to access components

for cleaning and maintenance. If any of the these conditions

cannot be met, the installer should provide special venting or air

ducts, as required.

IMPORTANT NOTE: For maximum efficiency, your new cabinet must be

lcated where an unrestricted air supply

can circulate aove and behind it. Never obstruct the face

of the condenser or the grill area in the front of the cabinet

and never place or store anything on the condenser or on

top of the cabinet machine compartment. These rules are

essential for long life. FAILURE TO FOLLOW THESE GUIDELINES MAY

VOID YOUR WARRANTY.

REACH-INS & ROLL-INS

OPERATIONS MANUAL

FLOOR LOADS

The floor at the final location site must be level, free of vibration

and strong enough to support the total combined weights of

your new model plus the maximum product load which might

be placed into it. Keep in mind that all the weight is concentrated

at the caster or leg locations. To estimate the possible product

weight, assume that each cubic foot of storage space weighs

approximately 35 pounds. Multiply 35 pounds by the amount of

cubic feet in the cabinet to obtain the product load weight.

For example, a 20 cubic foot refrigerator can hold approximately

700 pounds of product (35 x 20). Assuming the cabinet itself

weighs 300 pounds, the total combined weight of cabinet and

product is approximately 1000 pounds. Therefore, the floor in

this example must be able to support up to 1000 pounds.

INSTALLING CASTERS AND LEVELING

If your new unit is supplied with swivel casters, they will be

packed in the accessory box that came with your cabinet.

Casters should be installed only when the cabinet is close to

its final installation site. To install casters on your new model,

place wooden blocks along the back, at each end. Tilt the cabi-

net back, using the wood blocks to help hold the cabinet in its

tilted position. Locate the large threaded holes on the bottom

of the cabinet and screw the threaded caster studs into the

mounting holes, closest to the front of the unit. Repeat this

procedure by tilting the cabinet in the opposite direction and

installing the remaining casters. Make sure the casters are

tightened extremely well (see Figure 4 & 4A). If the casters are

not installed tightly, the cabinet will be unstable and may sway

or rock, which can damage the cabinet.

If the height of a caster needs to be raised, shims must be

installed under the casters which need leveling. Extra large

washers, available at most hardware or furniture stores, can

be used to shim casters, or contact the factory for caster

shims. For maximum stability under extreme conditions, caster

plate assemblies are available from the factory (see “Optional

Accessories” section of this manual).

Do not attempt to level casters by unscrewing them

from the cabinet and leaving them loose, as this will

cause damage to the cabinet and leg hole threads,

voiding all warranties.

OPERATIONS MANUAL

REACH-INS & ROLL-INS

INSTALLING LEGS AND LEVELING

If your new unit is supplied with adjustable legs, they will be

packed in the accessory carton in the cabinet. Your cabinet will

have either four (4) or (6) threaded mounting holes on the bot-

tom of the cabinet (see Figure 5). In order to install the legs,

carefully tip the cabinet back, adding four (4) 2” wood blocks

underneath, and simply screw the threaded leg studs into the

case bottom front leg holes. Repeat this procedure by tilting

the cabinet in the opposite direction and install the remaining

legs. Make sure the legs are tightened extremely well or the

entire model will sway or rock with each opening or closing of

the doors, possibly causing damage to the case bottom. This

procedure should be performed close to the final installation

site and allow access to the rear of the cabinet.

To assure your cabinet is level, all legs are equipped with bullet-

type leveling bolts. These bolts can be turned by hand or by

wrench, clockwise or counterclockwise to level the cabinet.

INSTALLING ROLL-IN AND ROLL-THRU MODELS

Roll-In and Roll-Thru models are designed to be mounted

directly (without legs or casters) on a flat floor surface in your

building (see Figure 6). The bottom off the cabinet is only

about ½” thick, to make it easy to roll carts up and into the

storage area. Roll-Ins and Roll-Thrus must be installed plumb

(vertically straight), level (horizontally even) and square for

proper operation of doors and refrigeration system. Proper

installation is similar to Walk-Ins and should only be done by a

qualified technician.

IMPORTANT NOTE: Proper installation and maintenance

is the responsibility of the customer. ANY DAMAGE OR

SERVICE REQUIRED, AS A RESULT OF INCOMPLETE

OR IMPROPER INSTALLATION, WILL NOT BE COVERED

UNDER WARRANTY. FAILURE TO PROPERLY INSTALL

AND LEVEL YOUR EQUIPMENT, INCLUDING, BUT NOT

LIMITED TO, THE INSTRUCTIONS PROVIDED IN THIS

MANUAL. MAY VOID YOUR WARRANTY.

length and width of the floor to provide enough support for the

cabinet and its contents.

NOTE: Shims and sealant are provided with all new roll-thru

models, to aide proper installation. Any shim material used

must be high density plastic, metal or other solid that will not

deteriorate due to moisture. Wedge shaped or flat shims 1/16”,

1/8” and 1/4” thick, and at least 3” wide to match thickness of

the cabinet walls, may be used. Failure to properly shim under

the entire floor of the cabinet will cause it to bend.

IMPORTANT NOTE: It is extremely important that your cabinet is

perfectly level for proper operation. If not level, the following adverse

conditions may occur:

1. The door(s) will not be properly aligned and consequently will not

provide a good seal.

2. Your unit may run excessively.

3. An excessive amount of ice will accumulate inside the cabinet,

around the door opening(s) and on the evaporator coil. If allowed

to continue, ice will eventually block the coil and the unit will fail.

This can result in the loss of all food stored in the cabinet.

4. Defrost water will fail to drain properly and will overflow the

evaporator coil drain pan and into the cabinet of both refrigerator

and freezer models.

CABINET AND DOOR ADJUSTMENT

After the unit is completely level, reinstall all grills, upper end

panels and ramps. Check alignment and adjust as required.

Caulk around the perimeter with NSF-approved sealant to

secure the cabinet in place and comply with sanitation require-

ments.

Reinstall all doors and verify gaskets seal properly. Adjust hing-

es as required (see “Door Removal and Adjusment”). Make

sure the adjustable flexible wiper on the bottom of each Roll-In

door gently contacts the ramp when the door is closed. Any

gaps must be eliminated, to avoid air leaks which will adversely

effect the performance of the refrigeration system. To check for

gaps, place a flashlight inside the cabinet, close the door(s) and

look under the door for visible light. Adjust the door wiper as

needed, by loosening the attachment screws slightly, then repo-

sition the wiper, recheck alignment, and retighten the screws.

NOTE: If your cabinet is adjacent to another Roll-Thru,

Tie-In Strips (see “Optional Accessories”) may be

installed for additional stability. Contact the factory for

more information and to order part kits.

SITE PREPARATION

IMPORTANT: The floor where any roll-in or roll-thru unit

is to be located must be level and flat. If not, it must be

made level prior to attempting to install the cabinet. THIS

IS CRITICAL FOR ROLL-THRU MODELS.

The best way to ensure a trouble-free installation is to have a

flat, level surface where the unit will be located, prior to setting

the cabinet in place. If the building floor is sloped or uneven,

due to floor drains or other conditions, a leveling bed should be

constructed. Otherwise it will be necessary to shim and anchor

the cabinet thoroughly, to ensure it remains stable and the doors

operate correctly. Make sure flooring is fully cured before mov-

ing the cabinet into position. Grout and concrete can release

chemicals while curing, which may corrode stainless steel.

CABINET INSTALLATION

Your cabinet should remain on the skid, with the protective

packaging in place, until transported to the final location. After

the cabinet is in the proper area, remove the door(s) by lifting

them off the hinges and setting in a safe location. Remove cart

ramp(s) at each opening by lifting off the fasteners attached to

the bottom face of the cabinet. The cabinet can be moved a short

distance, into its final position, by carefully pushing on the lower

half of the sides.

NOTE: Use care when handling the doors, as they are

large and heavy. Do not to damage the flexible wipers at

bottom of the doors. To avoid damaging or racking your

cabinet, only push on the sides at a height between 24”

and 48” from the floor.

CABINET LEVELING AND SHIMMING

After the cabinet is in its final location, remove the grills and

upper end panels. Place a 2 foot (or longer) carpenter’s along

the top edges and floor of the cabinet to check level. Use the

level to check if the sides of the cabinet are plumb (vertically).

Use a framing square to check the corners of the cabinet. If the

cabinet is not level, plumb and square, use a level to check the

cabinet floor in all directions and determine the highest area.

The cabinet must be shimmed to level the unit up to this point.

Determine the starting point for leveling, by identifying where

the cabinet is most plumb, straight and square. Insert a tapered

wedge under the adjacent walls, as needed, to raise them up to

a level position. Place shims under the side walls, on 12” cen-

ters or less, for adequate support along the entire length. After

the walls are level and plumb, place additional shims under the

OPERATIONS MANUAL

REACH-INS & ROLL-INS

CONDENSATE REMOVAL (Interior Coil Models)

No floor drains or plumbing connections are required since all

models use an automatic condensate water evaporating system.

Standard Reach-In models feature an evaporator housing,

located on the inside ceiling of the refrigerated storage area (see

Figure 2) and an electric condensate vaporizer pan with a mount-

ing bracket packed in the accessory carton.

To install the vaporizer, remove the pan, power cord, cord

clamp, aluminum drain tube, and screw from the carton (see

Figure 7A & 7B). Connect the cord to the vaporizer as shown.

Route the cord around the outside of the pan and through the

clamp as illustrated. Secure the cord and clip to the pan by

fastening the mounting screw into the threaded hole on the side

of the vaporizer. Position the bracket as shown and place the

vaporizer in the bracket, making sure the power cord is routed

as illustrated. Locate the drain tube that is zip tied to the vapor-

izer bracket and position the aluminum drain tube end vertically.

Slide the bracket onto the existing rear cabinet screws and con-

nect the aluminum drain tube end to the plastic tubing. Slide the

aluminum drain tube end down into the Pan, ensuring the plastic

tubing is not blocked or kinked, and the aluminum tube is not

pushing on the bottom of the vaporizer pan. For the alternative

drain tube (see Figure 7A), simply remove from carton, insert

the tube into the hole on the bracket and connect the other end

to the plastic tubing. Check that the water level switch is operat-

ing correctly by lightly pressing down on the top of the vapor-

izer, at the end where the cord is attached. You will hear

a “click”as pressure is applied and another “click”when pressure

is removed. If you do not hear the switch “click”, ensure

the vaporizer is seated in the bracket correctly and the cord is

routed correctly and secured in the clamp. Plug the power cord

into the receptacle labeled “VAPORIZER”on top of the cabinet.

IMPORTANT: It is extremely important that water level

switch operates correctly. Vaporizer should be plugged

into outlet on top of cabinet labeled “VAPORIZER”. If a

duplex receptacle is provided on the cabinet, compres-

sor must be securely plugged into receptacle labeled

“CONDENSING UNIT”. Improper installation may cause

cabinet or vaporizer to operate erratically. This can result

in water overflowing the pan and onto the floor.

CONDENSATE REMOVAL(Top Mount Coil Models)

Designer Line Reach-Ins, as well as all Pass-Thrus, Roll-Ins

and Roll-Thrus feature an insulated evaporator housing, located

on the top of the cabinet, out of the food zone (see Figure 2A

& 2B). These models utilize a unique self-contained hot air

evaporating system to automatically eliminate condensate water.

No floor drains or plumbing connections are required and the

system is completely self-contained, so no further assembly

or maintenance is required. In some adverse conditions such

as high ambient temperature, high humidity, extremely heavy

usage, frequent loading for prolonged periods of time, or heavy

pan loading, the amount of condensate water generated could

overflow the pan. If this occurs, the plastic drain tube from the

cabinet can be diverted directly to a floor drain, bypassing the

condensate pan. Alternatively, an optional electric condensate

vaporizer may be purchased as an accessory. An electric con-

densate vaporizer is also supplied with all remote reach-in and

pass-thru models. To install the optional condensate vaporizer,

follow the steps for “Interior Coil Models” in the previous sec-

tion. Remote roll-in and roll-thru models are supplied with an

electric heater in the condensate pan on top of the cabinet, which

must be connected to a power supply by the installer.

OPERATIONS MANUAL

DOOR REMOVAL AND ADJUSTMENT

During installation, it may become necessary to remove the

cabinet doors to facilitate passage through narrow doorways or

hallways. To remove a door, carefully pry off all hinge covers

using a sharp tool or plastic putty knife (see Figure 8). Swing

the door open 90° and carefully lift the door up, so the hinge

pins attached to the door clear the hinge bases mounted to

the cabinet. If it is necessary to remove the hinges, follow the

instructions below. To reinstall the door, reverse the above pro-

cedure. (For glass doors, see “Optional Accessories”).

All doors are aligned at the factory, however vibration during

transit may cause doors to shift and adjustment may be nec-

essary. If the door(s) require realignment, carefully pry off all

hinge covers (see Figure 8A) using a sharp tool or plastic putty

knife. Loosen the screws securing the hinge bases to the face

of the cabinet and slide the door into alignment. Hold the door

firmly in place and tighten all screws securely.

If the door gasket(s) do not seal properly to the cabinet face

or there are gaps between the gasket and the face on the hinge

side, adjust the door seal by removing the hinge covers and

loosening the adjustment screws securing the hinge pin to the

door. Push the face of the door towards the face of the cabinet,

so the gasket firmly contacts the cabinet. Do not press the door

too tight against the cabinet, or the gasket will pinch along the

hinge side and the door will not close and seal properly. Hold

the door firmly in place and tighten all screws securely. Open

and close the door several times to check that the gasket seals

properly all the way around the door. Re-adjust if necessary.

HINGE REMOVAL AND REPLACEMENT

Before attempting any work on your refrigerator or freezer,

always disconnect power by unplugging the cabinet, or

switching off the circuit breaker. It is strongly recommended

that you also remove all contents and store them in a walk-in

or other refrigerated space. The following tools are needed to

remove the hinge: plastic putty knife and philips screwdriver

with large (#3) tip.

To remove the hinge pin from the door (see Figure 8A) loosen

the adjustment screws and remove the adjustment plate and pin.

To remove the hinge base from the face of the cabinet loosen

the (3) flat-head machine screws. Use caution when removing

the top hinge base, as it contains the light switch. To remove the

lock keeper from the cabinet, remove the 2 screws on the inside

edge of the keeper (see Figure 8) and slide it off the base. If the

white, nylon cam needs to be removed from the hinge base, a

plastic putty knife may be used to carefully pry the cam out of

the body. Be careful not to damage the cam, as the nylon mate-

rial is soft.

RE-HINGING DOORS (Reach-Ins)

Single section, solid long door models are rehingeable in the

field, without the need to modify the cabinet. A plastic putty

knife, a philips screwdriver and wire crimpers will be needed.

Before attempting to rehinge your unit, unload all contents and

store in walk-in or other refrigerated space. Disconnect power

to the cabinet. Open the door 90° and lift it off the hinge bases.

Remove the hinge pins from the door (see instructions above).

Reverse each pin by rotating it 180° and reattaching to the door.

Remove the hinge bases and lock keeper(s) from the front of the

cabinet (see above). Use caution when removing the top hinge

Remove the filler screws and plug button from the face of the

cabinet, on the opposite side (new hinge locations). Wires for

connecting the light switch will be coiled up in the insulation,

behind the plug button. Carefully pull the wires out and install

female push-on connectors. Remove the old light switch from

the original top hinge location by disconnecting the push-on wire

terminals. Cap each lead wire separately, push the wires into the

insulation and insert the plug button into the hole. Connect the

light switch to the wire terminals at the new top hinge location.

To finish the cabinet wiring modifications, remove the cover

from the control box, on top of the cabinet. There will be a black

lamp cord, with a tag identifying it as the light switch wire. Install

(2) female wire connectors on the black lamp cord. There will

be (2) brown lamp cord leads on the terminal block. Disconnect

them and replace with the wires from the black lamp cord. Cut

off the old leads on the brown ripcord and secure them out of

the way, so they will not contact any live wiring. Check that all

wires are properly connected and secured. Replace the control

box cover.

Remount the hinge bases to the face of the cabinet. Install the

light switch into the top hinge base by sliding the flanged edge

into the slot on the back side of the base. Remount the lock

keeper and door. Adjust the doors as needed and reconnect

power to the cabinet.

NOTE: All wiring and connections should only be made by

a qualified electrician.

REMOVING GRILL

To remove the grill, loosen, but do not remove, the (4) mounting

screws located on the back side of the grill at the ends. Simply

lift grill up off of its mounting screws and out. To replace the

grill, line up the grill mounting screws with the keyhole slots

located on the cabinet body, push in and down on the grill.

IMPORTANT NOTE: The wiring to the anti-condensate

switch and the thin copper tubing or cable for the ther-

mometer are provided with leads long enough to allow

the grill to be laid across the top of the cabinet after it

has been removed. Take care not to damage the wires or

copper tubing when handling the grill.

If you need to completely remove the grill from the cabinet,

disconnect the power supply to the cabinet. Remove the wires

on the back of the anti-condensate switch on the grill. Locate the

thermometer sensing bulb and cover, located inside the cabinet.

On Standard Reach-In models, the thermometer bulb cover

is under a small cover channel on the interior top left corner

towards the front of the cabinet. On Designer Line, Pass-Thru,

Roll-In and Roll-Thru models, the thermometer bulb is located

on the interior top, under the air duct. Remove the cover, care-

fully grasp the bulb and push it back through the cabinet hole.

The thermometer bulb and grill can now be removed from the

cabinet. When reinstalling the thermometer bulb, be sure to

replace the sealant putty around the hole into the insulation.

Reattach the leads for the anti-condensate heater switch and

reconnect the cabinet’s power supply.

INITIAL CLEANING PROCEDURE

Prior to start-up and before placing any product inside of your

new model, the interior of the cabinet should be thoroughly

cleaned. Remove the protective film (which is clear on some

models) from all interior sides, bottom and other internal metal

panels, by working the corner loose and slowly pulling the film

back. Washing with a mild soap and warm water solution is

recommended for cleaning the aluminum and stainless steel

surfaces of your cabinet. This should be followed by cleaning

with a baking soda solution (three (3) tablespoons of baking

soda to each quart of warm water). Wipe down thoroughly with

a damp cloth or sponge that has been soaked in clean water and

wrung out thoroughly, and dry with a clean, soft cloth.

IMPORTANT NOTE: Never use harsh detergents, clean-

ers, scouring powders or chemicals when cleaning your

model. Failure to dry the interior surfaces after cleaning

may result in a streaking or staining of the metal.

Complete cleaning procedures and precautions are listed in the

(“Periodic Cleaning Procedure” under “Maintenance”).

START-UP PROCEDURE

ELECTRICAL CONNECTIONS

To insure proper operation, your new model must be connected

to an individual circuit that can supply the full voltage as stated

on the cabinet serial data plate. For correct voltage, power draw,

and wire accommodations, check the data on the serial data

plate located on the inner right wall of your new model. Verify

that this information exactly matches the electrical character-

istics at the installation location. An electrical wiring diagram,

located on the inside compressor compartment rear, next to

the electrical console box, should also be consulted during

REACH-INS & ROLL-INS

OPERATIONS MANUAL

connection. For reference, a copy of each electrical wiring dia-

gram is located towards the back of this manual (see “Wiring

Diagrams” section).

Refrigeration compressors are designed to operate within

+/-10% of the rated voltage indicated on the cabinet serial

plate. Excessively high or low supply power can burnout the

compressor. This can be easily detected and will void the fac-

tory warranty. Full voltage at the correct rating, on a separate,

designated circuit, not affected by the operation of other electri-

cal appliances, must be available to the refrigeration unit at all

times. Extension cords should never be used on commercial

equipment, as they can overheat and/or result in low voltage.

GFI/GFCI RECEPTACLES

Ground-Fault Circuit Interrupter (GFCI or GFI) devices are not

recommended for most commercial refrigerators and freezers,

since nuisance trips may occur, typically due to moisture. This

can cause temporary loss of power, which may result in high

storage temperatures and potentially unsafe food product.

Building codes in some areas may require certain 115 volt

receptacles to be protected by a GFI. If you need to connect your

equipment to a protected circuit, a properly sized, commercial

grade GFI circuit breaker should be used on a separate, isolated

power supply. Or a qualified electrician may be able to hard wire

your equipment, eliminating the need for a GFI device. Contact

Continental’s Service Department before making any modifica-

tions to your cabinet, to avoid loss of warranty.

NOTE: GFI RECEPTACLES ARE NOT RECOMMENDED,

PRODUCT LOSS OR SERVICE PROBLEMS RESULTING

FROM NUISANCE TRIPS, CONNECTION TO A DEFECTIVE

OR IMPROPER POWER SUPPLY, AND UNAUTHORIZED

MODIFICATIONS TO YOUR EQUIPMENT CAN CAUSE A

HAZARD AND WILL VOID FACTORY WARRANTY.

115 VOLT, 60 HZ, 1 PHASE CONNECTION

All 115 volt models are provided with a

factory installed, UL approved 15-amp

power cord and NEMA 5-15P plug, or a

20-amp power cord and NEMA 5-20P plug.

To insure proper operation, this

equipment must be plugged into a

NEMA compatible, grounded receptacle

that can supply the full voltage and amperage

stated on the serial plate (see Figure 1).

09/03/10

IMPORTANT NOTE: A SEPARATE, ISOLATED, PROPERLY

SIZED POWER SUPPLY MUST BE PROVIDED. GFCI

DEVICES AND/OR EXTENSION CORDS SHOULD NOT

BE USED. PRODUCT LOSS, AS WELL AS PROBLEMS

RESULTING FROM NUISANCE TRIPS OR HIGH/LOW

VOLTAGE, ARE NOT COVERED UNDER WARRANTY.

CAUTION: IF UNIT IS UNPLUGGED OR DISCONNECTED

FOR ANY REASON, ALLOW 5-6 MINUTES BEFORE

TURNING THE UNIT BACK ON TO ALLOW THE SYSTEM

TO EQUALIZE. DISREGARDING THIS PROCEDURE

COULD CAUSE AN OVERLOAD AND PREVENT THE UNIT

FROM OPERATING.

115/208-230 VOLT, 60 HZ, 1 PHASE CONNECTION

All 115/208-230 volt models are provided with three (3) sup-

ply wires, which exit the electrical box located in the machine

compartment rear, next to the compressor. The cabinet circuitry

is 115 volts and the condensing unit operates on 208-230 volts.

A permanently connected, 3-wire (plus ground) power supply is

required, consisting of (2) hot conductors and (1) neutral wire,

plus (1) ground wire. The supply leads must be connected to

the appropriate leads from the cabinet and the supply ground

wire must be attached to the electrical box with a ground lug

to provide proper grounding of the metal cabinet and chassis.

All wiring and connections should only be made by a qualified

electrician and must conform to all local electrical codes.

IMPORTANT NOTE: IF THE SUPPLY CORD IS DAMAGED, IT

MUST BE REPLACED BY THE MANUFACTURER, ITS SERVICE

AGENT, OR SIMILARLY QUALIFIED PERSONS IN ORDER TO

AVOID A HAZARD.

SPECIAL VOLTAGE CONNECTIONS

When models are ordered from the factory with special voltages,

connections should be made as required on the electrical wiring

diagram provided next to the electrical control box.

START-UP CHECKLIST

After your unit has been installed and electrically connected in

accordance with this manual, please take time to check the fol-

lowing before loading product, to assure trouble-free operation:

q Sufficient clearance and ventilation provided around

cabinet (see “Ventilation”)

q Unit connected to separate power supply at correct

voltage (see “Electrical Connections”)

OPERATIONS MANUAL

REACH-INS & ROLL-INS

q Cabinet is level and casters/legs are tight

(see “Installation and Location”)

q Doors close and seal properly

(see “Door Removal and Adjustment”)

q Cabinet operating at correct temperature

(see “System and Adjustment”)

q Thermometer properly calibrated

(see “Thermometer and Calibration”)

q Condensate vaporizer installed correctly

(see “Condensate Removal”)

q All refrigeration lines free of kinks and excess vibration

(see “Refrigeration System”)

q Condenser and evaporator fans rotate freely

(see “Refrigeration System”)

q Freezers only: defrost time clock set correctly

(see “Freezer System and Adjustment”)

q All pilaster clips installed securely and shelves are level

(see “Shelving Installation”)

q All packing materials discarded and cabinet properly

cleaned (see “Periodic Cleaning”)

The system should run smooth and quietly in accordance

with generally accepted commercial standards. If any unusual

noises are heard, turn the unit off immediately and check for any

obstructions of the condenser or evaporator fans. Fan motors,

fan blades, or fan housings can be jarred out of position through

rough handling in transit or during installation.

OPERATION

All cabinets must be given sufficient time to reach normal oper-

ating temperature before placing any product inside cabinet.

Refrigerators are designed to maintain an ideal cabinet tem-

perature of 38° to 40°F (3.3° to 4.4°C). Approximately 1 hour

of operation is required to reach this temperature. Freezers are

designed to maintain an ideal cabinet temperature of -4° to 0°F

(-20° to -18°C). Approximately 2 hours of operation are required

to reach this temperature.

REFRIGERATION SYSTEM AND ADJUSTMENT

All self-contained refrigerators are designed and factory set to

maintain an average cabinet temperature of 38° to 40°F (3.3° to

4.4°C). The temperature control is accessible from the top of the

electrical console box located on the cabinet top behind the front

grill (see Figure 9, 9A & 9B).

IMPORTANT NOTE: All refrigerators are designed with

automatic, “off-cycle” defrost system meaning defrosting

occurs automatically when compressor is not operat-

ing during an off-cycle. Do not set electronic control

too cold where cabinet temperature will fall below 35°F.

Evaporator will become blocked by ice since compressor

off-cycle will be considerably shortened. This will result

in loss of food stored within cabinet and require service.

FREEZER SYSTEM AND ADJUSTMENT

All self-contained freezers are factory set to maintain an average

cabinet temperature of -4° to 0°F (-20° to -18°C). These prod-

ucts are designed to hold pre-frozen food and although they are

capable of freezing small quantities of fresh food, they are not to

be used as fast or blast freezers. DO NOT ATTEMPT TO FREEZE

BULK QUANTITIES OF FRESH FOODS.

The temperature control is accessible from the top of the electri-

cal console box located on the cabinet top behind the front grill

(see Figure 9, 9A & 9B).

DEFROST OPERATION

All freezer models are equipped with an automatic, electric

defrost system, consisting of evaporator coil defrost and drain

pan heater(s). During each defrost period, the condensing unit

and evaporator fans go off, while the defrost heater(s) are ener-

gized. After termination of a defrost cycle, the heaters go off and

the condensing unit turns on. The evaporator fans remain off

(for about 20 minutes) until the coil cools down to a preset tem-

perature (typically 32°F). This defrost drip time, which allows

any remaining water to clear off the evaporator coil, also ensures

that only cold air is circulated throughout the storage compart-

ment. t for the correct time after power is restored, to maintain

the same time of day for defrost.

In some extreme applications, where there is very heavy usage,

excessively high humidity and/or constant door openings, addi-

tional defrost period(s) may be desired to ensure your evapora-

tor remains free of any frost accumulation.

REACH-INS & ROLL-INS

OPERATIONS MANUAL

All standard reach-in refrigerators and freezers built after June,

2009 have a unique, modular refrigeration system. The com-

plete, fully charged refrigeration unit can be easily removed from

the cabinet for locations with restricted access for installation,

servicing, conversion from a refrigerator to freezer (or vice

versa) or other needs. Contact the service department for more

information.

TOP-MOUNT PLUG BOX REFRIGERATION SYSTEM

(Evaporator Housing on Top of Cabinet)

The plug-type evaporator system is a unique system in which

the evaporator coil and air circulating fans are contained within

a concealed plug-type insulated housing, readily accessible on

the top of the cabinet and separate from the food storage zone

(see Figure 9A & 9B). The entire plug system is fully charged

with refrigerant and mounted on a steel rail type base which can

be removed from the cabinet for locations with restricted access

for installations, or if a field conversion (refrigerator to freezer or

vice versa) is desired. Before attempting to remove plug assem-

bly, consult factory.

IMPORTANT NOTE: After defrost the automatic fan delay

prevents evaporator fans from operating until the coil has

reached a preset temperature, minimizing warm air circu-

lation in cabinet. During start-up and after a defrost cycle,

fans will not turn on immediately. Settings should only be

adjusted as noted, to minimize electrical cosumption and

provide efficient heating cycle. Contact the factory before

making modifications to any settings not described

above. Improper adjustments can cause problems with

unit, including loss of product and evaporator freeze ups,

which are not covered under warranty.

WARMER SYSTEM AND ADJUSTMENT

All Designer Line warming cabinets are designed with an operat-

ing range of 60°F to 180°F and factory performance run tested

to maintain an average cabinet temperature of 150°F. Always

preheat your new warming cabinet to the desired temperature

before placing any food into it. When the desired temperature

is reached and displayed on the electronic control, preheating is

complete and the cabinet is ready to be loaded. Please note that

setting the electronic control higher than the desired tempera-

ture will not provide quicker preheat warm-ups.

Warming cabinets are not designed to cook food. All foods

placed in the warming cabinet should be precooked and at, or

above the desired holding temperature. Never place cold or

uncooked foods in the cabinet. It is recommended that hot

foods be kept above 140°F to retard bacterial growth. Foods that

are steaming should always be covered.

IMPORTANT NOTE: Operating range of warmer tempera-

ture control is 60°F to 180°F. Never allow cabinet tem-

perature to exceed 200°F. Serious damage could result to

warming cabinet and warranty will become null and void.

STANDARD REACH-IN REFRIGERATION SYSTEM

(Ceiling-Mount Evaporator)

The low-profile evaporator system is comprised of a gener-

ous sized, evenly matched evaporator and air circulating fans

contained within an easily accessible, low silhouette, interior

ceiling mounted housing (see Figure 9). A control box, located

on top of the cabinet, contains the temperature control, thermal

limit switch, defrost time clock (for freezers) and other electrical

components.

INTERIOR ACCESSORIES

Your new cabinet comes with (3) shelves per section for stan-

dard solid door models, or (4) shelves per section for glass door

models, and (4) support clips per shelf.

SHELVING INSTALLATION

Pilaster strips for mounting the shelves are secured to the cabi-

net walls with special screws which allow the strips to be readily

removed for cleaning without the use of tools. To install the

shelving, determine the desired location for the shelves in each

section of your cabinet. For proper airflow, the bottom shelf in

each section should be installed with the clips at the lowest posi-

tion on the pilaster strip, to provide space for sufficient airflow

under and around the product.

IMPORTANT NOTE: When locating your shelves, allow

space between each row of product. A minimum clear-

ance of 2” is recommended below the bottom product

for air circulation.

Shelf clips are easily installed by inserting them into the pilasters

at the desired shelf locations. To install a shelf, simply place it

on the (4) clips, making sure that the clips are located properly,

so the shelf is level and supported at each corner. Standard and

optional heavy duty pilasters and clips are shown in Figure 10.

REACH-INS & ROLL-INS

OPERATIONS MANUAL

To ensure proper air flow inside wall your cabinet, some interior

standard models are provided with product stops that snap onto

the shelves (see Figure 10B). To install the product stop, place

it over the shelf as shown and press it down onto the shelf. If

necessary, carefully pull out on the ends of the product stop,

so the bottom of the rod snaps over the shelf wire. Press down

on the hooks at ends of the product stop, so they snap over the

back of the shelf frame. Repeat for remaining shelves. Make sure

all shelves are installed with the product stops positioned at the

back of your cabinet.

MAINTENANCE

PRODUCT LOADING

Product load should be evenly distributed over each shelf and

through the cabinet. Standard shelving will hold up to 125 lbs

and heavy duty shelves will hold up to 225 lbs, evenly distrib-

uted. For proper performance on standard ceiling-mount coil

models, maintain at least a 2” air space from product to the back

wall and to the coil housing. For top-mount plug box models, a

minimum 2” clearance should be maintained from the face of the

top and side walls (see Figure 10A).

IMPORTANT NOTE: LOADING PRODUCT TOO CLOSE

TO THE WALLS OR PANELS WILL RESTRICT AIRFLOW,

RESULTING IN POOR PERFORMANCE AND SERVICE

ISSUES, SUCH AS COIL FREEZE-UP, WHICH WILL NOT

BE COVERED BY WARRANTY.

SAFETY PRECAUTIONS

DISCONNECT POWER BEFORE ATTEMPTING TO WORK

ON OR CLEAN EQUIPMENT. DO NOT ATTEMPT TO

REMOVE ANY COVERS OR PARTS YOURSELF, AS

THIS CAN EXPOSE DANGEROUS, HIGH VOLTAGE

WIRING. SERVICE SHOULD ONLY BE PERFORMED BY

A QUALIFIED TECHNICIAN.

ALWAYS ROUTE POWER CORDS AWAY FROM AREAS

WHERE THEY CAN BE WALKED ON OR DAMAGED BY

OTHER EQUIPMENT. YOUR APPLIANCE IS EQUIPPED

WITH A POLARIZED, GROUNDED POWER PLUG. NEVER

ATTEMPT TO REMOVE THE GROUND POST OR USE

A NON-POLARIZED ADAPTER, WITHOUT PROPERLY

GROUNDING THE EQUIPMENT.

CONDENSER FINS ARE MADE FROM THIN METAL AND

HAVE SHARP EDGES. ALWAYS WEAR GLOVES AND

USE CAUTION WHEN WORKING ON OR AROUND THE

CONDENSING UNIT TO PREVENT CUTS AND AVOID

DAMAGING FINS, TUBING AND OTHER COMPONENTS.

KEEP ELECTRICAL COMPONENTS AND CONTROLS DRY.

DO NOT SPRAY WITH WATER! FAILURE TO FOLLOW

THESE INSTRUCTIONS CAN CAUSE A SAFETY HAZARD

AND VOID FACTORY WARRANTY.

PERIODIC CLEANING PROCEDURE

It is always best to clean your refrigerator or freezer when the

product load in your cabinet is as its lowest level. To clean the

interior or exterior cabinet surfaces, follow these procedures:

1. Disconnect your cabinet from its power supply and remove

all product from inside.

2. Open all doors and allow the cabinet to reach room temp-

erature. Remove all accessories (shelves, pilasters, clips,

etc.) from inside and wash them with a baking soda

and warm water solution, wipe thoroughly with clean water.

Dry all accessories completely with a soft clean cloth.

3. Once the cabinet has reached room temperature, wash the

inside and outside surfaces with a solution of warm water

and baking soda. Pay particular attention to the face of the

cabinet, as any residue or debris can impair the door seal.

For slightly more difficult cleanups, ammonia or vinegar in

warm water can be used. Wipe down thoroughly with a

damp cloth or sponge that has been soaked in clean water

and wrung out thoroughly, and dry with a clean, soft cloth.

Carefully wash all of the vinyl door gaskets with clean

water, dry them and check for any damage, which may

affect the seal. Failure to dry all surfaces completely may

cause water stains or streaking on the aluminum or stain-

less steel finish.

4. Return all accessories to their original locations, reconnect

the power. Wait at least 1 hour before reloading product.

CLEANING PRECAUTIONS

NEVER USE HARSH DETERGENTS, ABRASIVE

CLEANERS, OR CHEMICALS CONTAINING HALOGENS

(CHLORINE, FLUORINE, IODINE, ETC.) WHEN

CLEANING YOUR UNIT. CONCENTRATED CHEMICALS

CAN CAUSE DISCOLORING, ALWAYS WIPE THEM OFF

IMMEDIATELY IF CONTACT OCCURS. SEE “CLEANING

OF STAINLESS STEEL” FOR MORE INFORMATION.

AVOID SPLASHING THE CABINET WITH WATER AND

CHEMICALS WHEN MOPPING FLOORS OR CLEANING

OTHER EQUIPMENT AROUND IT.

GENERAL PREVENTATIVE MAINTENANCE

The most important thing you can do to maintain any refrigera-

tor or freezer and extend its life, is to keep the condenser clean.

Performance of the air-cooled condensing unit, located on top of

the cabinet, depends exclusively upon the amount of air passing

through the condenser fins. Your refrigerator or freezer will run

more efficiently, consume less energy, and provide a maximum

of trouble-free service throughout its lifetime if the condenser

coil is kept clean and an adequate supply of clean, cool air is

provided at all times. Periodically (at least once a month) it is

important to inspect the condenser coil for any debris or block-

age that may have accumulated.

If the condenser coil is dirty or dusty, disconnect the cabinet

power supply and use a stiff brush to wipe away any dirt and

debris from the condenser fins. Using a vacuum cleaner with a

brush attachment may aid in this process. After cleaning, restore

electrical service to your cabinet.

IMPORTANT!

AFTER-MARKET CONDENSER FILTERS ARE NOT

PERMITTED BECAUSE THEY HINDER AIRFLOW.

FAILURE TO KEEP THE CONDENSER CLEAN AND

FREE FROM OBSTRUCTIONS WILL CAUSE EXCESSIVE

COMPRESSOR LOAD, REDUCING THE PERFORMANCE

OF YOUR UNIT. THIS CAN RESULT IN PREMATURE

FAILURE AND WILL VOID YOUR WARRANTY.

REACH-INS & ROLL-INS

OPERATIONS MANUAL

DO NOT USE: abrasive

cleaners, chemicals with

chlorides or muriatic

acid to clean your

equipment.

3. HARD WATER causes spots and stains on stainless steel

surfaces, particularly when it is heated. Find out the hard-

ness of your water and treat it properly, if needed. Use a

water filter and softeners if you have hard water. Club soda

can be used to remove streaks or spots.

DO NOT USE: hot or hard water to clean stainless steel.

CLEAN YOUR STAINLESS STEEL REGULARLY using the proper

tools and cleaners. After cleaning, always wipe, wipe, wipe

thoroughly with cool, clean, clear water.

CHECK ALL OF YOUR EQUIPMENT PERIODICALLY. If you see

any signs of rust, clean the area immediately, with a plastic

scrubbing pad. If surface rust is removed promptly, permanent

corrosion, pits and cracks may be avoided. Special stainless

steel polishes, that can help restore the protective coating on

your equipment, are available from a variety of retailers.

IMPORTANT: If these recommendations are not followed,

the protective film on your stainless steel can break down

and your equipment may begin the long walk down the

dark road of corrosion.

CARE AND CLEANING OF STAINLESS STEEL*

*Some information and graphics for this section were obtained from “Stainless

Steel Equipment Care and Cleaning” brochure, published by the North American

Association of Food Equipment Manufacturers (NAFEM).

Contrary to popular beliefs, stainless steel can rust, if not prop-

erly cared for and maintained (That’s why it’s called stain-LESS

steel, not stain-PROOF steel.)

All steel is primarily made of

iron. Stainless steels contain

other metals, such as chromi-

um and nickel, that provide an

invisible film on the surface of

the steel that acts as a shield

against corrosion. As long as

this invisible layer is intact and

not broken or contaminated,

the metal will retain its cor-

rosion protection and remain

stain-less.

There are 3 basic things that can break down the protective

layer on your stainless steel, which must be avoided:

1. MECHANICAL ABRASION is caused by things that

scratch the surface of the metal. Only use soft cloths or

plastic scouring pads to clean and always scrub in the

same directions as the metal grain.

DO NOT USE: abrasive cleaners, steel pads, wire

brushes, scrapers or knives to clean your equipment.

2. CHLORIDES are found in water, salt, food and worst

of all, many cleaners. Only use chloride-free, alkaline-

based, non-abrasive cleaners. Always wipe thoroughly

with cool, clean water and dry with a soft towel. A solu-

tion of 1 tablespoon baking soda mixed with 1 pint water

can be used to remove tough stains.

REACH-INS & ROLL-INS

OPERATIONS MANUAL

the following shall be completed prior to conducting work on

the system.

a. Work procedure

Work shall be undertaken under a controlled procedure

so as to minimize the risk of a flammable gas or vapor being

present while the work is being performed.

b. General work area

All maintenance staff and others working in the local

area shall be instructed on the nature of work being carried out.

Work in confined spaces shall be avoided.

c. Checking for presence of refrigerant

The area shall be checked with an appropriate refriger-

ant detector prior to and during work, to ensure the techni-

cian is aware of potentially toxic or flammable atmospheres.

Ensure that the leak detection equipment being used is suit-

able for use with all applicable refrigerants, i.e., nonsparking,

adequately sealed, or intrinsically safe.

d. Presence of fire extinguisher

If any hot work is to be conducted on the refrigerating

equipment or any associated parts, appropriate fire extinguish-

ing equipment shall be available on hand. A dry chemical or CO2

fire extinguisher should be adjacent to the charging area.

e. No ignition sources

No person carrying out work in relation to a refrigerat-

ing system which involves exposing any pipe work shall use any

sources of ignition in such a manner that it may lead to the risk

of fire or explosion. All possible ignition sources, including ciga-

rette smoking, should be kept sufficiently far away from the site

of installation, repairing, removing and disposal, during which

refrigerant can possibly be released to the surrounding space.

Prior to work taking place, the area around the e q u i p -

ment shall be surveyed to make sure that there are no flammable

hazards or ignition risks. “No Smoking” signs shall be displayed.

2. Ventilated area

Ensure that the area is in the open or that it is adequately ven-

tilated before breaking into the system or conducting any hot

work. A degree of ventilation shall continue during the period

that the work is carried out. The ventilation should safely dis-

perse any released refrigerant and preferably expel it externally

into the atmosphere.

3. Checks to the refrigerating equipment

Where electrical components are being changed, they shall be

fit for the purpose and to the correct specification. At all times,

the manufacturer’s maintenance and service guidelines shall

be followed. If in doubt, consult the manufacturer’s technical

department for assistance. The following checks shall be applied

to installations using flammable refrigerants:

a. the actual refrigerant charge is in accordance with

the room size within which the refrigerant containing parts are

installed;

b. the ventilation machinery and outlets are operating

adequately and are not obstructed;

c. if an indirect refrigerating circuit is being used, the

secondary circuit shall be checked for the presence of refriger-

ant;

d. marking to the equipment continues to be visible and

legible. Markings and signs that are illegible shall be corrected;

e. refrigerating pipe or components are installed in a

position where they are unlikely to be exposed to any substance

which may corrode refrigerant containing components, unless

the components are constructed of materials which are inher-

ently resistant to being corroded or are suitably protected

against being so corroded.

4. Checks to electrical devices

Repair and maintenance to electrical components shall include

initial safety checks and component inspection procedures. If a

fault exists that could compromise safety, then no electrical sup-

ply shall be connected to the circuit until it is satisfactorily dealt

with. If the fault cannot be corrected immediately but it is neces-

sary to continue operation, an adequate temporary solution shall

be used. This shall be reported to the owner of the equipment,

so all parties are advised. Initial safety checks shall include:

a. that capacitors are discharged: this shall be done in

a safe manner to avoid possibility of sparking;

b. that no live electrical components and wiring are

exposed while charging, recovering or purging the system;

c. that there is continuity of earth bonding.

REPAIRS TO SEALED COMPONENTS

1. During repairs to sealed components, all electrical supplies

shall be disconnected from the equipment being worked upon

prior to any removal of sealed covers, etc. If it is absolutely

necessary to have an electrical supply to equipment during

servicing, then a permanently operating form of leak detection

shall be located at the most critical point to warn of a potentially

hazardous situation.

2. Particular attention shall be paid to the following to ensure

that by working on electrical components, the casing is not

altered in such a way that the level of protection is affected. This

shall include damage to cables, excessive number of connec-

tions, terminals not made to original specification, damage to

seals, incorrect fitting of glands, etc. Ensure that the apparatus

is mounted securely. Ensure that seals or sealing materials

have not degraded to the point that they no longer serve the

purpose of preventing the ingress of flammable atmospheres.

Replacement parts shall be in accordance with the manufac-

turer’s specifications.

OPERATIONS MANUAL

REACH-INS & ROLL-INS

REPAIR TO INTRINSICALLY SAFE COMPONENTS

Do not apply any permanent inductive or capacitance loads

to the circuit without ensuring that this will not exceed the

permissible voltage and current permitted for the equipment

in use. Intrinsically safe components are the only types that

can be worked on while live in the presence of a flammable

atmosphere. The test apparatus shall be at the correct rating.

Replace components only with parts specified by the manufac-

turer. Other parts can result in the ignition of refrigerant in the

atmosphere from a leak. NOTE The use of silicon sealant can

inhibit the effectiveness of some types of leak detection equip-

ment. Intrinsically safe components do not have to be isolated

prior to working on them.

CABLING

Check that all cabling will not be subject to wear, corros-

ing, excessive pressure, vibration, sharp edges, or any other

adverse environmental effects. The check shall also take into

account the effects of again or continual vibrationfrom sources

such as compressors or fans.

END-OF-LIFE DISPOSAL

OF REFRIGERATED EQUIPMENT

Your unit is designed and built to provide many years of reli-

able service. At the end of its useful life, please follow the steps

below for safe disposal, to help avoid accidents and to protect

the environment.

1. Remove all doors to eliminate any potential for accidental

child entrapment.

2. All refrigerant should be removed from the system by a

qualified technician and disposed of properly, or reclaimed.

(Intentional venting of many refrigerants into the air is

harmful and prohibited; violators are subject to fines). All

refrigerant oil should be drained from the compressor and

discarded appropriately.

3. Properly dispose of the cabinet and refrigeration system

components. The majority of the metal in your unit (stain-

less steel or aluminum cabinet shell and doors, steel shelv-

ing and compressor, copper refrigerant lines, etc.) can be

recycled. Many recycling facilities will dispose of the unit

free of charge, or pay you for scrap value of the material

content.

OPTIONAL ACCESSORIES

GUIDELINES FOR TECHNICIAN

Decommissioning

Before carrying out this procedure, it is essential that the techni-

cian is completely familiar with the equipment and all its detail. It

is recommended good practice that all refrigerants are recovered

safely. Prior to the task being carried out, an oil and refrigerant

sample shall be taken in case analysis is required prior to re-use

of recovered refrigerant. It is essential that electrical power is

available before the task is commenced.

1. Become familiar with the equipment and its operation.

2. Isolate the system electrically.

3. Before attempting the procedure, ensure that:

a. mechanical handling equipment is available, if

required, for handling refrigerant cylinders;

b. all personal protective equipment is available and

being used correctly;

c. the recovery process is supervised at all times by a

competent person;

d. recovery equipment and cylinders conform to the

appropriate standards.

4. Pump down refrigerant system, if possible.

5. If a vacuum is not possible, make a manifold so that refriger-

ant can be removed from various parts of the system.

6. Make sure that cylinder is situated on the scales before recov-

ery takes place.

7. Start the recovery machine and operate in accordance with

instructions.

8. Do not overfill cylinders (no more than 80 % volume liquid

charge).

9. Do not exceed the maximum working pressure of the cylinder,

even temporarily.

10. When the cylinders have been filled correctly and the pro-

cess completed, make sure that the cylinders and the equipment

are removed from site promptly and all isolation valves on the

equipment are closed off.

11. Recovered refrigerant shall not be charged into another

refrigerating system unless it has been cleaned and checked.

Labelling

Equipment shall be labelled stating that it has been de-com-

missioned and emptied of refrigerant. The label shall be dated

and signed. For appliances containing flammable refrigerants,

ensure that there are labels on the equipment stating the equip-

ment contains FLAMMABLE REFRIGERANT.

RECOVERY

When removing refrigerant from a system, either for servicing

or decommissioning, it is recommended good practice that all

REACH-INS & ROLL-INS

OPERATIONS MANUAL

refrigerants are removed safely. When transferring refrigerant

into cylinders, ensure that only appropriate refrigerant recov-

ery cylinders are employed. Ensure that the correct number of

cylinders for holding the total system charge is available. All

cylinders to be used are designated for the recovered refriger-

ant and labelled for that refrigerant (i.e., special cylinders for

the recovery of refrigerant). Cylinders shall be complete with

pressure-relief valve and associated shut-off valves in good

working order. Empty recovery cylinders are evacuated and, if

possible, cooled before recovery occurs. The recovery equip-

ment shall be in good working order with a set of instructions

concerning the equipment that is at hand and shall be suit-

able for the recovery of all appropriate refrigerants including,

when applicable, flammable refrigerants. In addition, a set of

calibrated weighing scales shall be available and in good work-

ing order. Hoses shall be complete with leak-free disconnect

couplings and in good condition. Before using the recovery

machine, check that it is in satisfactory working order, has

been properly maintained and that any associated electrical

components are sealed to prevent ignition in the event of

a refrigerant release. Consult manufacturer if in doubt. The

recovered refrigerant shall be returned to the refrigerant sup-

plier in the correct recovery cylinder, and the relevant waste

transfer note arranged. Do not mix refrigerants in recovery

units and especially not in cylinders. If compressors or

compressor oils are to be removed, ensure that they have

been evacuated to an acceptable level to make certain that

flammable refrigerant does not remain within the lubricant.

The evacuation process shall be carried out prior to return-

ing the compressor to the suppliers. Only electric heating to

the compressor body shall be employed to accelerate this

process. When oil is drained from a system, it shall be carried

out safely.

PAN SLIDE ASSEMBLIES

Pan slide assemblies are available in a variety of configurations

(see Figure 11). The unique design of the vertical supports

allow the pan slides to be mounted on 1” centers and be read-

ily removed for cleaning, without the use of tools or additional

hardware. If your new unit was ordered from the factory with

pan slides, the vertical supports will be pre-installed directly on

the outer walls of the cabinet. On 2- and 3-section cabinets, the

vertical pan supports in the middle of the cabinet are mounted

to center supports as shown (see Figure 11A). The pan slides

are wrapped up in the accessory package, inside the cabinet.

FIGURE 11: Pan Slide Assembly Configurations

PAN SLIDE INSTALLATION

Pan slides should be installed in pairs, to ensure each set is

level at the same height. Before installing the slides, determine

the spacing desired between each pan that will be placed in the

cabinet. Align one of the pan slides against the vertical support

(see Figure 11A). Simultaneously insert the (2) studs on the

slide into the upper end of the slot on the vertical supports at the

desired height and the pan slide will simply drop down and lock

into place. Install another slide into opposite vertical supports,

using the same method. Check that the pair of slides are level

and at the proper height. Repeat this procedure for the remain-

ing sets of pan slides.

HINGED GLASS DOOR REMOVAL

AND ADJUSTMENT

Removal and adjustment of hinged glass doors are similar to

solid doors except that heated glass doors have an electrical

cord attached to the cabinet. Before attempting to remove a

glass door, disconnect the cabinet from the power supply. Using

a phillips screwdriver, loosen the retaining screw from the mold-

ed plug and gently pull the plug out of the molded receptacle.

Carefully pry off all hinge covers using a sharp tool or knife (see

Figure 12). Swing the door to the open position (90°) and care-

fully lift the door upward, so the hinge pin (attached to the door)

clears the hinge body (mounted to the cabinet). If it is necessary

to remove the hinge bodies from the cabinet, use caution when

loosening the top hinge body, as they contain the light switch

actuator (see Figure 8A).

SLIDING GLASS DOOR REMOVAL

AND ADJUSTMENT

All sliding glass doors are easily removable for thorough clean-

ing. To remove the doors, slide the outer door (see Figure

13) open about half way, grasp the door on both sides and lift

straight up, off roller track, which will remain in the mounting

frame. Tilt the bottom of the door out, so it clears the locating

studs on the roller track and the bottom of the mounting frame.

Gently set the door down, being careful not to over-stretch the

self-closing spring and power cord that are attached to the top of

the door. Move the door towards its closed position, to release

any tension on the spring and power cord. The roller track will

simply lift out of the channel in the bottom of the mounting

frame. Repeat this procedure for the inner door.

To replace the doors, reverse the steps above, making sure the

door seats properly over the locating studs on the roller track.

If your sliding door does not close firmly, remove the doors,

starting with the outer door, as described above. Check the bot-

tom of the door, mounting frame channel, and rollers to make

sure they are clean and free of debris. If the rollers are damaged

or do not turn freely, contact the factory to order replacement

parts. The tension on the self-closing spring is adjustable, to

provide quicker and firmer closing, or to provide slower and

more gentle movement. Remove the screw attaching the end

of the self-closing spring to the top of the door. Note that there

are (3) threaded holes provided in the top of the door. To adjust

the door so it closes slower, reattach the spring at a position

closer to the handle side of the door. For a faster, firmer closing,

relocate the spring at a position further away from the handle

side of the door.

If the door does not seal evenly along the handle side when

in the closed position, the tilt of the door is adjustable. A flat

washer can be placed over the locating stud on the top of the

roller track, between the track and the underside of the door, to

level the door. For example: if the door contacts the mounting

frame at the top when it is closed, but there is a gap at the lower

half of the side edge, remove the door as described above. After

lifting the door off the roller track, place a flat washer over the

stud located closest to the handle side of the door. Replace the

door, recheck the seal, and readjust if needed. (To close a gap at

the upper half of the door, place a washer over the locating stud

farthest from the handle side of the door.)

IMPORTANT NOTE: The glass used in sliding or hinged

glass doors is of special, sealed pane design and can

not be replaced with ordinary window or plate glass.

If it becomes necessary to replace the glass, it can be

obtained directly from the factory.

While in transit, your cabinet is subjected to more jarring and

vibration than at any other time, and the display may require

some adjustment at start-up. Refrigerators are designed to

maintain 38° to 40°F (3.3° to 4.4°C) and Freezers -2° to 0°F

(-19° to -18°C). During periods of heavy use, when doors

are opened repeatedly or remain open for extended period,

or if warm product is loaded in the cabinet, the temperature

displayed may temporarily exceed the “normal” range. This is

common, as warm air outside the cabinet mixes with cold air

inside. If your thermometer continues to display temperature

above “normal” range, close the doors, make sure they seal

tight and keep them closed for at least 30 minutes. If a high

temperature is still displayed, check the thermometer by plac-

ing a pre-calibrated temperature sensing device in the center

of the refrigerated compartment and keep the doors closed for

at least 15 minutes. The thermometer should display the same

temperature as the sensing device, within +/-2°F (+/-1°C). If

it does not, follow instructions below for calibration mode to

adjust the offset.

MOUNTING CASTER SUPPORT PLATES

If casters on a cabinet are not properly maintained and tight-

ened, or if the unit is excessively overloaded and moved around,

the threaded inserts in the bottom of the cabinet can become

stripped, twisted or collapsed. If this occurs and the stem cast-

ers cannot be mounted securely, rigid caster support plates can

be fitted to provide the strength needed to safely use your cabi-

net. Each caster support plate assembly is made of heavy gauge

galvanized steel, with (2) casters permanently welded to it, for

maximum rigidity. The plate has a series of holes that will allow

you to fasten the plate assembly to the bottom of the cabinet

with sheet metal screws and bolts. Contact the factory to obtain

the correct parts for your model.

IMPORTANT NOTE: Always wear proper work gloves and

use appropriate safety equipment. You may CAREFULLY

lay the cabinet on its back, but only FOR A BRIEF PERIOD

OF TIME. Caution must be taken to ensure you DO NOT

DAMAGE the back or side panels, as well as the copper

tubing and refrigeration components located on top of

your cabinet. The cabinet must be properly blocked, to

allow room to get your hands in to lift without damaging

the cabinet or crushing the end panels. DO NOT PLUG-IN

OR OPERATE THE REFRIGERATION SYSTEM FOR AT

LEAST THREE (3) HOURS AFTER THE UNIT HAS BEEN

RETURNED TO AN UPRIGHT POSITION, AS THIS CAN

DAMAGE THE COMPRESSOR.

To install caster support plate assemblies, you will need a 3/4”

open end wrench (or a large adjustable wrench), a drill with a

1/8” bit and a Phillips bit (or a Phillips-Head screwdriver) plus

work gloves. A 1/2-13 thread tap is also recommended, to repair

any damage to the threaded inserts in the cabinet. Unload all

product and carefully lay the cabinet on its back. Remove the old

stem casters by unscrewing them from the cabinet. If a caster or

threaded insert has been stripped or cross-threaded, it may be

necessary to use a wrench to loosen the caster.

Hold one of the support plate assemblies under the cabinet as

shown (see Figure 14). Position it so the slotted holes at the end

of the plate line up with the threaded inserts in the bottom of the

cabinet (where the stem casters were attached). Attach the plate

assembly to the cabinet by putting a 1/2” x 1-3/4” long bolts and

flat washer through the slot in the support plate and screwing

into each of the threaded inserts in the bottom of the cabinet.

Snug the bolts down, but do not tighten them completely. If

one of the threaded inserts is stripped or damaged, a thread tap

should be used to clean the threads.

OPERATIONS MANUAL

REACH-INS & ROLL-INS

Using the small holes in the plate as a template, drill 1/8 pilot

holes in the bottom of the cabinet. (Note: drill only until you

penetrate the metal bottom of the cabinet. Do not continue

to drill into the insulation, or you may damage the cabinet.)

Secure the caster support plate assembly to the cabinet with a

sheet metal screw in each of the drilled holes. Tighten the 1/2”

bolts. Repeat these steps to attach the other plate assembly to

the opposite end of the cabinet.

Check that both plates are secure and that the casters turn

and swivel freely. Carefully lift the cabinet upright and double

check that the caster support plates are secure and the cabinet

is stable. Wait at least 3 hours before turning the refrigeration

system back on, and at least another 30 minutes for the cabinet

to come down to temperature and stabilize, before reloading

with product.

INSTALLATION OF TIE-IN STRAPS

Roll-Thru Cabinets

If two cabinets are installed side-by-side, a Tie-In Kit with straps

and notched upper end panels is available to attach to the cabi-

nets for rigidity. Before installing Tie-In Strips, make sure the

cabinets are close together and each unit is properly leveled (see

Installing Roll-In and Roll-Thru Models).

Remove the front and rear grill from each cabinet, by lifting off

mounting screws on the back side at each end (screws may

need to be loosened, before grill will lift up). Remove upper end

panel on the side of each cabinet located next to an adjacent

cabinet, by loosening the mounting screws along the bottom.

Make sure the cabinets are pushed tightly together. Gap between

the cabinets must be no more ¼” wide. Position Tie-In Strap

as shown in Figure 15 across the top of the gap between the

cabinets. Re-check that the cabinets are aligned properly and

secure the Tie-In Strap to the top of each cabinet with self-

drilling screws. Position one of the notched upper end panels

as shown on the first cabinet, with the notch at the bottom, and

attach to the cabinet with sheetmetal screws at front and back

corners. Position the other notched upper end panel as shown

on the second cabinet, with the notch at bottom, and attach to

the cabinet with sheetmetal screws at front and back corners.

Reinstall the front and rear grills on each cabinet by inserting

mounting screws on the back side at each end into the keyhole

slots on the end panels. Check that the grills and doors are

straight and properly aligned. Adjust if necessary. Apply a bead

of silicone in the vertical seems between the cabinets at front

and back side.

NOTE: This is necessary to comply with sanitation

requirements and also makes it apparent that the cabinets

have been attached together.

OPERATIONS MANUAL

REMOTE SET-UP AND INSTALLATION GUIDELINES

All remote refrigerators and freezers are shipped with an expan-

sion valve, thermostat and defrost timer (freezer only), installed

from the factory. The installer is responsible for connecting all

refrigerant lines, liquid line drier, sight glass, solenoid, head

pressure control, hi/low pressure safety, crankcase heater, con-

densing unit and any other accessories as well as wiring. The

evaporator section has been factory leak checked with helium,

however; due to vibration in transit, the entire system must be

thoroughly leak checked after installation and prior to start-up.

The final leak inspection of the entire completed refrigeration

system and all of its components as well as start-up and the

operation of the refrigeration system is the sole responsibility

of the installer.

The CFC-Free refrigerant used in standard remote and self-

contained models is R-134a for refrigerators and R-404a for

freezers. All compressors and systems designed for these

FIGURE 15: Installation of Tie Straps for Roll-Thru Cabinets

refrigerants utilize polyolester oil as their main lubricant, which

absorbs moisture from the ambient surroundings extremely fast

and in much greater quantity than conventional mineral oils.

Since moisture levels greater than 100 PPM will result in system

corrosion and ultimate failure, it is imperative that the compres-

sor, components and entire system be kept sealed.

1. Piping material, pipe routing, and installation shall include

protection from physical damage in operation and service, and

be in compliance with national and local codes and standards,

such as ANSI/ASHRAE 15, IAPMO Uniform Mechanical Code,

ICC International Mechanical Code, or CSA B52. All field joints

shall be accessible for inspection prior to being covered or

enclosed.

2. The installation of pipe-work shall be kept to a minimum.

3. Mechanical connections shall be accessible for maintenance

purposes.

4. Provision shall be made for expansion and contraction of

long runs of piping.

5. Protection devices, piping, and fittings shall be protected

as far as possible against adverse environmental effects, for

example, the danger of water collecting and freezing in relief

pipes or the accumulation of dirt and debris.

6. Piping in refrigeration systems shall be so designed and

installed to minimize the likelihood of hydraulic shock damaging

the system.

7. Steel pipes and components shall be protected against cor-

rosion with a rustproof coating before applying any insulation.

8. Flexible pipe elements shall be protected against mechanical

damage, excessive stress by torsion, or other forces, and that

they should be checked for mechanical damage annually.

9. Precautions shall be taken to avoid excessive vibration or

pulsation

10. All refrigerant lines and components must be clean, free

of burrs and purged with nitrogen prior to and during brazing

or soldering connections. Nitrogen purging during brazing or

soldering will eliminate carbon or foreign matter contamination.

Any system restrictions or contamination is the responsibility of

the installer.

11. Condensing unit or compressor shall not be left open to the

atmosphere for more than five (5) minutes.

12. No refrigeration component, tubing or fitting shall be left

open to the atmosphere for more than ½ hour without being

soldered, capped or plugged.

13. Each completed refrigeration system shall be purged with

150psi of dry nitrogen for at least six (6) seconds, then pressur-

ized with at least 165psi of nitrogen for pressure check (making

sure to energize any solenoid valves to assure access). Leak-

check all joints, flare fittings and valves and make sure there is

no pressure drop within the system.

14. System evacuation is of the utmost importance with NON-

CFC refrigerant systems. System must be evacuated to a

minimum of 200 microns. In addition, a vacuum decay test is

strongly recommended to assure there is not a large pressure

differential between the system and the vacuum pump. System

must be evacuated from both high and low sides of the system

using heavy duty vacuum hoses.

15. Each system should be charged with the refrigerant type as

specified on the cabinet data tag. This refrigerant type should

match the type listed on the condensing unit being used. The

refrigerant charge should be held to the minimum required

for the satisfactory pull down and operation. For an accurate

indication of refrigerant charge, the sight glass will show a full

column of liquid.

16. The superheat reading taken 6” from the compressor suction

valve should be 30° +/- 5°. Expansion valve adjustment may be

necessary to achieve this superheat.

17. Installation of the electric condensate vaporizer is also

the responsibility of the installer (see “Installing Electric

Condensate Vaporizer” under “optional Accessories”).

FISH FILE MODELS

Fish File models are provided with drawers specially designed

for the storage of fresh fish, or similar product, packed in

crushed ice. Each drawer has a removable pan, with a drain

tube at the back corner (see Figure 16). Water from melting ice

in the pan, along with moisture from the product, drains out of

the storage pan through the tube, along a trough on the interior

cabinet wall, down to the sloped interior bottom, and out of the

cabinet through a 1” drain tube.

INSTALLATION AND LOCATION

In addition to normal considerations (see Installation and

Location), Fish File units should be installed directly over a

building floor drain, to rapidly dispose of water from melted ice

that drains out of the cabinet. It is also highly recommended that

your Fish File is located near a water source that can be used to

thoroughly wash down your cabinet regularly.

NOTE: If a building floor drain is not immediately avail-

able, a waste line, with consistent downward slope, must

be supplied and connected to the 1” NPS drain tube

located under the cabinet. An electric condensate vapor-

izer cannot be used to dispose of water from melted ice,

as the liquid waste contains food residue that can cause

unpleasant odors and potentially unsanitary conditions.

LOADING AND STORING PRODUCT

When loading your cabinet, place a layer of ice in the drawer

pan first, then add a layer of food product, and then add another

layer of ice. Repeat this pattern until product is at least 1” from

the top of the pan, and then add a final layer of ice to cover

the product. Throughout the day, fresh ice should be added to

always keep the product covered. Periodically check the drain

tube at the back of the drawer pan and remove any debris, which

could allow excess water to accumulate in the pan. Cabinet tem-

perature can be adjusted to approximately 36°F (2°C), to prevent

the ice from melting too quickly.

FIGURE 16: Fish File Components

REACH-INS & ROLL-INS

OPERATIONS MANUAL

Fish should be stored at temperatures as close to 32°F (0°C) as

possible and should never exceed 39°F (4°C). Food product that

has been packed in ice must not be kept in the drawers over-

night, as this can allow for elevated temperatures and excessive

thawing, which will quickly degrade product quality. Always fol-

low proper procedures for handling, storing, thawing and cook-

ing any type of food, to eliminate potential for any contamination

or bacteria growth.

CLEANING AND MAINTENANCE

In addition to normal cleaning, (see Periodic Cleaning

Procedure) the entire interior of your Fish File, including the

drawers and storage pans, must be thoroughly cleaned and

sanitized daily, to prevent excessive build-up of food residue,

which can cause unpleasant odors and potentially unsanitary

conditions. At the end of each day, remove any remaining food

product from the drawers and move it to suitable refrigerated

storage, or discard it.

Lift each food pan up and out of the drawer frame, being careful

not to damage the drain tube. Run the pans through a dishwash-

er, or properly clean and sanitize them manually. Remove each

drawer assembly by pulling it out of the cabinet, until the front

roller wheels stop against the front of the slides. Lift up the front

of the drawer, so the wheels come up and out of the slide tracks.

Pull the drawer further out, until the rear wheels stop against

the front of the slides. Lift the drawer again, so the back wheels

clear the drawer slides. Thoroughly wash the drawer frame

and components properly (see Care and Cleaning of Stainless

Steel). Carefully wash the drawer gaskets thoroughly with clean

water, dry them and check for any damage. To re-install the

drawers and pans, reverse the above procedure.

NOTE: On 2-section Fish Files, pans must be installed

with drain toward the outside cabinet wall, so the drain

tube is directly aver the drain trough.

Detection of ammable refrigerants

Under no circumstances shall any potential sources of ignition

be used in the searching for or detection of refrigerant leaks. A

halide torch (or any other detector using a naked ame) shall not

be used.

The following leak detection methods are deemed acceptable for

all refrigerant systems:

Electronic leak detectors may be used to detect refrigerant leaks

but, in the case of ammable refrigerants, the sensitivity might

not be adequate, or might need recalibration. (Detection equip-

ment shall be calibrated in a refrigerant-free area.)

Ensure that the detector is not a potential source of ignition and is

suitable for the refrigerant used. Leak detection equipment shall

be set at a percentage of the LFL of the refrigerant and shall be

calibrated to the refrigerant employed, and the appropriate per-

centage of gas (25 % maximum) is conrmed.

Leak detection uids are also suitable for use with most refriger-

ants but the use of detergents containing chlorine shall be avoid-

ed as the chlorine can react with the refrigerant and corrode the

copper pipe-work. NOTE Examples of leak detection uids are

– bubble method, – uorescent method agents.

If a leak is suspected, all naked ames shall be removed/extin-

guished. If a leakage of refrigerant is found which requires braz-

ing, all of the refrigerant shall be recovered from the system, or

isolated (by means of shut off valves) in a part of the system

remote from the leak. Removal of refrigerant shall be according

to Removal and evacuation below.

Removal and evacuation

When breaking into the refrigerant circuit to make repairs – or

for any other purpose – conventional procedures shall be used.

However, for ammable refrigerants it is important that best

practice be followed, since ammability is a consideration. The

following procedure shall be adhered to:

1. safely remove refrigerant following local and national regula-

tions;

2. purge the circuit with inert gas;

3. evacuate (optional for A2L);

4. purge with inert gas (optional for A2L);

5. open the circuit by cutting or brazing.

The refrigerant charge shall be recovered into the correct recov-

ery cylinders if venting is not allowed by local and national codes.

For appliances containing ammable refrigerants the system

shall be purged with oxygen-free nitrogen to render the appliance

safe for ammable refrigerants. This process might need to be

repeated several times. Compressed air or oxygen shall not be

used for purging refrigerant systems.

For appliances containing ammable refrigerants, refrigerants

purging shall be achieved by breaking the vacuum in the sys-

tem with oxygen-free nitrogen and continuing to ll until the

working pressure is achieved, then venting to atmosphere, and

nally pulling down to a vacuum (optional for A2L). This pro-

cess shall be repeated until no refrigerant is within the system

(optional for A2L). When the nal oxygen-free nitrogen charge

is used, the system shall be vented down to atmospheric pres-

sure to enable work to take place.

Ensure that the outlet for the vacuum pump is not close to any

potential ignition sources and that ventilation is available.

Charging procedures

In addition to conventional charging procedures, the following

requirements shall be followed.

1. Ensure that contamination of different refrigerants does not

occur when using charging equipment. Hoses or lines shall be

as short as possible to minimize the amount of refrigerant con-

tained in them.

2. Cylinders shall be kept in an appropriate position according

to the instructions.

3. Ensure that the refrigerating system is earthed prior to charg-

ing the system with refrigerant.

4. Label the system when charging is complete (if not already).

5. Extreme care shall be taken not to overll the refrigerating

system.

Prior to recharging the system, it shall be pressure-tested with

the appropriate purging gas. The system shall be leak-tested on

completion of charging but prior to commissioning. A follow up

leak test shall be carried out prior to leaving the site.

and the warranty applies only if our examination finds the parts, equipment, or compressor defective. The use of non-authorized services or non-

OEM parts voids the validity of this warranty. Defective parts must be returned to us within thirty (30) days. The return should include the cabinet

model, serial number, and a return material authorization number provided by the manufacturer. This warranty does not cover any shipping costs.

The labor warranty covers self-contained units only, during standard working hours, and excludes overtime rates. Before employing labor, the

purchaser must contact the factory for service authorization by calling directly or requesting service through our website. To be covered, purchasers

must supply a labor invoice along with the service authorization number within thirty (30) days of the date of completion. In any event, all work must

be completed within ninety (90) days of the service authorization date. This warranty does not cover special installations or applications, including

those in remote locations. Any installation that requires additional work or travel to access the unit for service is the responsibility of the purchaser.

THIS WARRANTY REPLACES ALL OTHER EXPRESS, IMPLIED, OR STATUTORY WARRANTIES, INCLUDING IMPLIED WARRANTIES OF

MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE, WHICH ARE HEREBY DISCLAIMED. WE DO NOT ASSUME, NOR AUTHORIZE

OTHERS TO ASSUME, ANY OBLIGATION OR LIABILITY RELATED TO THE SALE OF THESE PRODUCTS.

This warranty is valid only for the original purchaser and cannot be assigned.

This warranty is void outside the USA and Canada and does not cover misuse, neglect, alteration, accidents, or damage from transportation, flood,

fire, acts of terrorism, acts of God, or natural disasters, as determined solely by Continental Refrigerator.

CONTINENTAL REFRIGERATOR SHALL IN NO EVENT BE LIABLE FOR CONSEQUENTIAL OR SPECIAL DAMAGES, INCLUDING INDIRECT, PUNITIVE,

LOSS OF USE, PRODUCT LOSS, DOWNTIME, OR LOST PROFITS, RELATED TO THE PRODUCT OR ITS USE. THE PURCHASER’S REMEDIES ARE

EXCLUSIVE. CONTINENTAL REFRIGERATOR’S TOTAL LIABILITY WILL NOT EXCEED THE PURCHASE PRICE OF THE COMPONENT IN QUESTION,

REGARDLESS OF CONTRACT, WARRANTY, NEGLIGENCE, INDEMNIFICATION, STRICT LIABILITY, TORT, OR OTHER GROUNDS.
