RECEIVING & INSPECTING THE EQUIPMENT

Even though most equipment is shipped crated, care should be taken during

unloading so the equipment is not damaged while being moved into the building.

1. Visually inspect the exterior of the package and skid or container. Any

damage should be noted and reported to the delivering carrier immediately.

2. If damaged, open and inspect the contents with the carrier.

3. In the event that the exterior is not damaged, yet upon opening, there is

concealed damage to the equipment, notify the carrier. Notiﬁcation should

be made verbally as well as in written form.

4. Request an inspection by the shipping company of the damaged equipment.

This should be done within 10 days from receipt of the equipment.

5. Be certain to check the compressor compartment housing and visually

inspect the refrigeration package. Be sure lines are secure and base is still

intact.

6. Freight carriers can supply the necessary damage forms upon request.

7. Retain all crating material until an inspection has been made or waived.

INSTALLATION

NOTE:

UNIT REPAIRS WILL NOT BE SUBJECT TO STANDARD UNIT WARRANTIES IF

DUE TO IMPROPER INSTALLATION PROCEDURES.

DANGER:

THE UNIT MUST BE TURNED OFF AND DISCONNECTED FROM THE POWER

SOURCE WHENEVER PERFORMING SERVICE, MAINTENANCE FUNCTIONS OR

CLEANING THE REFRIGERATED AREA.

LOCATION: Units represented in this manual are intended for indoor use only. Be

sure the location chosen has a ﬂoor strong enough to support the total weight of

the cabinet and contents. A fully loaded unit can weigh as much as 1500 pounds.

Reinforce the ﬂoor as necessary to provide for maximum loading. For the most

efﬁcient refrigeration, be sure to provide good air circulation inside and out

INSIDE CABINET: Do not pack the units so full that air cannot circulate. The

refrigerated air is discharged at the top rear of the unit. It is important to allow

for proper air ﬂow from the top rear to the bottom of the unit. Obstructions to

this air ﬂow can cause evaporator coil freeze ups and loss of temperature or

overﬂow of water from the evaporator drain pan. The shelves have a rear turn up

on them to prevent this. However, bags and other items can still be located to the

far rear of the cabinet. Air is brought into the evaporator coil with fans mounted

to the front of the coil.

OUTSIDE CABINET: Be sure that the unit has access to ample air. Avoid hot

corners and locations near stoves and ovens. It is recommended that the unit be

installed no closer than 2” from any wall with at least 12” of clear space above

the unit.

LEVELING: A level cabinet looks better and will perform better because the

doors will line up with the frames properly. Use a level to make sure the unit

is level from front to back and side to side. Units supplied with legs will have

adjustable bullet feet to make the necessary adjustments. If the unit is supplied

with casters, no adjustments are available. Ensure the ﬂoor where the unit is to

be located is level.

STABLING: All models are supplied with casters for your convenience. It is very

important, however, that the cabinet be installed in a stable condition with the

front wheels locked while in use. Should it become necessary to lay the unit on

its side or back for any reason, allow at least 24 hours before start-up to allow

compressor oil to ﬂow back into place. Failure to meet this requirement can

cause compressor failure and unit damage.

ELECTRICAL CONNECTION: Refer to the amperage data on page 1, the serial tag,

your local code or the National Electrical Code to be sure the unit is connected

to the proper power source.

OPERATION

CAUTION: DO NOT THROW ITEMS INTO THE STORAGE AREA. FAILURE TO HEED THESE

RECOMMENDATIONS COULD RESULT IN DAMAGE TO THE INTERIOR OF THE

CABINET.

REFRIGERATED CYCLE

Refrigerators: During the refrigeration cycle, the evaporator fans wilt run

continuously even when one or more doors are open. The door switch will activate

the lights when opened.

1. Every 6 hours, the unit will turn off and to allow the evaporator coil to defrost. The

controller now displays defrost symbol. When the coil temperature reaches 41°F

or after 20 minutes of defrost, the unit will turn on again.

2. Anti-condensation heaters on door frames work in conjunction with the

compressor.

3. The factory setting for the temperature range is 34°F to 38° F.

Freezers:

During the refrigeration cycle, the controller supplies power to the

condensing unit and evaporator fan motors. The evaporator fans will run at any time

when the evaporator coil temperature is below 54°F. They will also keep running

when door is open but cycle off during a defrost period. The door switch will activate

the lights when opened.

1. Every 6 hours, the unit will turn off and electric heater will turn on to defrost. The

controller now displays the defrost symbol. When the coil temperature reaches

45°F or after 20 minutes of defrost, the unit will turn on again.

2. Anti-condensation heaters on door frames work in conjunction with the

compressor.

3. The factory setting for temperature range is -7 to -3°F

MAINTENANCE

DANGER:

THE UNIT MUST BE TURNED OFF AND DISCONNECTED FROM THE POWER

SOURCE WHENEVER PERFORMING SERVICE, MAINTENANCE FUNCTIONS OR

CLEANING THE REFRIGERATED AREA.

DANGER:

NEVER USE A HIGH PRESSURE WATER WASH FOR THIS CLEANING

PROCEDURE AS WATER CAN DAMAGE THE ELECTRICAL COMPONENTS

LOCATED NEAR OR AT THE CONDENSER COIL.

DANGER: NEVER USE STEEL PADS, WIRE BRUSHES OR SCRAPERS!

CAUTION: NEVER USE AN ACID BASED CLEANING SOLUTION！MANY FOOD PRODUCTS

HAVE AN ACIDIC CONTENT WHICH CAN DETERIORATE THE FINISH. BE SURE

TO CLEAN THE STAINLESS STEEL SURFACES OF ALL FOOD PRODUCTS.

REFRIGERATORS AND FREEZERS

The interior and exterior can be cleaned using soap and warm water. If this isn’t

sufﬁcient, try ammonia and water or a nonabrasive liquid cleaner. When cleaning

the exterior, always rub with the “grain” of the stainless steel to avoid marring

the ﬁnish.

Do not use an abrasive cleaner because it will scratch the stainless steel and

plastic and can damage the breaker strips and gaskets.

CLEANING THE CONDENSER COIL

The condenser coil requires regular cleaning and it is recommended every 90

days. In some instances, you may ﬁnd that there is a large amount of debris and

dust or grease accumulated prior to the 90 day time frame. In these cases the

condenser coil should be cleaned every 30 days.

If the build up on the coil consists of only light dust and debris, the condenser

coil can be cleaned with a simple brush. Heavier dust build-up may require a

vacuum or even compressed air to blow through the condenser coil.

If heavy grease is present, there are de-greasing agents available for refrigeration

use and speciﬁcally for the condenser coils. The condenser coil may require

cleaning with the de-greasing agent and then blown through with compressed

air.

Failure to maintain a clean condenser coil can initially cause high temperatures

and excessive run times. Continuous operation with dirty or clogged condenser

coils can result in compressor failures. Neglecting the condenser coil cleaning

procedures will void any warranties associated with the compressor or cost to

replace the compressor.

In order to maintain proper refrigeration performance, the condenser ﬁns must

be cleaned of dust, dirt and grease regularly. It is recommended that this be

done at least every three months. If conditions are such that the condenser is

totally blocked in three months, the frequency of cleaning should be increased.

Clean the condenser with a vacuum cleaner or stiff brush. If extremely dirty, a

commercial-grade condenser cleaner may be required.

STAINLESS STEEL CARE AND CLEANING

To prevent discoloration of rust on stainless steel several important steps need to

be taken. First, we need to understand the properties of stainless steel. Stainless

steel contains 70-80% iron which will rust. It also contains 12-30% chromium

which forms an invisible passive ﬁlm over the steels surface which acts as a

shield against corrosion. As long as the protective layer is intact, the metal is still

stainless. If the ﬁlm is broken or contaminated, outside elements can begin to

breakdown the steel and begin to form rust of discoloration. Proper cleaning of

stainless steel requires soft cloths or plastic scouring pads, Cleaning solutions

need to be alkaline based or non-chloride based. Any cleaner containing

chlorides will damage the protective ﬁlm of the stainless steel. Chlorides are

commonly found in hard water, salts, and household and industrial cleaners.

If cleaners containing chlorides are used, be sure to rinse and dry thoroughly.

Routine cleaning of stainless steel can be done with soap and water. Extreme

stains or grease should be cleaned with a non-abrasive cleaner and plastic scrub

pad. It is always good to rub with the grain of the steel. There are also stainless

steel cleaners available which can restore and preserve the ﬁnish of the steel’s

protective layer.

Early signs of stainless steel breakdown can consist of small pits and cracks.

If this has begun, clean thoroughly and start to apply stainless steel cleaners in

attempt to restore the passivity of the steel.

GASKET MAINTENANCE

Gaskets require regular cleaning to prevent mold and mildew build up and also

to keep the elasticity of the gasket. Gasket cleaning can be done with the use of

warm soapy water. Avoid full strength cleaning products on gaskets as this can

cause them to become brittle and prevent proper seals. Do not use sharp tools

or knives to scrape or clean the gasket which could possibly tear the gasket and

rip the bellows.

Gaskets can easily be replaced and don’t require the use of tools or authorized

service technicians. The gaskets are “Dart” style and can be pulled out of the

grove in the door and replaced by pressing the new one back into place.

DOORS/HINGES

Over time and with heavy use, door hinges may become loose. If the door is

beginning to sag, tighten the screws that mount the hinge brackets to the frame

of the unit. If the doors are loose or sagging, this can cause the hinge to pull out

of the frame which may damage both the doors and the door hinges.

DRAIN MAINTENANCE

Each unit has a drain located inside the unit which removes the condensation

from the evaporator coil and evaporates it into an external condensate evaporator

pan. Each drain can become loose or disconnected from moving or bumping the

drain. If you notice excessive water accumulation on the inside of the unit, be

sure the drain tube is connected from the evaporator housing to the condensate

evaporator drain pan. If water starts to collect underneath the unit, you may want

to check the condensate evaporator drain tube to be sure it is still located inside

the drain pan. The leveling of the unit is important as the units are designed to

drain properly when on a level surface, if your ﬂoor is not level, this can also

cause drain problems. Be sure all drain lines are free of obstructions because

this may cause water to back up and overﬂow the drain pans.
