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.

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 refrigerator 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.

Prevent obstruction by locating large boxes and tall stacks of product to the

bottom of the cabinet.

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. Should

it become necessary to lay the unit on its side or back for any reason, allow at

least 24 hours before start-up so as to allow compressor oil to ﬂow back to the

sump. Failure to meet this requirement can cause compressor failure and unit

damage.

LEVELING

A level cabinet looks better and will perform better because the doors will line up

with the frames properly, the cabinet will not be subject to undue strain and the

contents of the cabinet will not move around on the shelves. 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.

STABILIZING

Models are supplied on casters for your convenience, ease of cleaning

underneath and for mobility. It is very important, however, that the cabinet be

installed in a stable condition with the front wheels locked while in use.

ELECTRICAL CONNECTION

Refer to the amperage data, the serial tag, your local code or the National

Electrical Code to be sure the unit is connected to the proper power source. A

protected circuit of the correct voltage and amperage must be run for connection

of the line cord, or permanent connection to the unit.

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.

REFRIGERATION CYCLE

During the refrigeration cycle, the controller supplies power to the condensing

unit and evaporator fan motors. The evaporator fan will run at any time when the

evaporator coil temperature is below 54°F and it will cycle off during the defrost

period. Every 6 hours, the unit will turn off and the defrost heater will work to

clear up the ice. 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.

1. Anti-Condensation heaters on the door frames work in conjunction with the

compressor.

2. The factory setting of the temperature range is -7 to -3°F

LIGHT SWITCH: A light switch is located next to the on/off switch on the front of

the bottom panel.

MAINTENANCE

DANGER:

THE POWER MUST BE TURNED OFF AND THE UNIT 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. Recommended cleaning is 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 a

spray 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 repeatedly

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 steels

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 to 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.

SWING DOOR REPLACEMENT AND ADJUSTMENT

1. Open the bottom panel and hold the door. Then loosen the bottom hinge

screw and take off the old door.

2. Prepare new door; insert top pin into top hinge, get one bottom hinge to hold

the door with the bottom pin. Fasten bottom hinge securely to the door frame

with three screws.

3. Allow the door to freely swing, making sure it swings closed by itself with no

restriction.

4. Plug the unit in and make sure the lock works well.

5. If not, adjust the door height by adding the plastic spacer/washer provided

with the bottom hinge pin.

REMOVE THE BOTTOM PANEL

Loosen and remove the top screws, slide the panel up and out

LIGHT BULB REPLACEMENT

1. Upper light bulb replacement: Loosen the screws in the bottom of the top

panel and swing the panel up until the light bulb is exposed. Light bulb can

then be changed.

2. LED light bulb replacement: Take the cover off to replace the LED light bulb.
