SERIAL NUMBER INFORMATION
The serial number of all self-contained refrigerators and freezers is located inside the unit on the left hand
side near the top on the wall.
Always have the serial number of your unit available when calling for parts or service.
This manual covers standard units only. If you have a custom unit, consult the customer service
department at the number listed on the last page.
RECEIVING AND 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. Notication 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.

Service, Installation and Care Manual
INSTALLATION
LOCATION
Units represented in this manual are intended for indoor use only. Be sure the location chosen has a oor
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 oor as necessary to provide for maximum loading. For the most ef-
cient 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 ow from the top rear to the bottom of the unit. Obstructions
to this air ow can cause evaporator coil freeze ups and loss of temperature or overow 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 adjust-
ments are available. Ensure the oor where the unit is to be located is level.
STABILIZING
All models are supplied with 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.
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 ow back into place. Failure to meet this
requirement can cause compressor failure and unit damage.
Unit repairs will not be subject to standard unit warranties if due to improper
installation procedures.
ELECTRICAL CONNECTION
Refer to the amperage data on page 3, the serial tag, your local code or the National Electrical Code to be
sure the unit is connected to the proper power source.
The unit must be turned OFF and disconnected from the power source whenever performing
service, maintenance functions or cleaning the refrigerated area.

MAINTENANCE
The unit must be turned OFF and disconnected from the power source whenever
performing service, maintenance functions or cleaning the refrigerated area.
REFRIGERATORS AND FREEZERS
The interior and exterior can be cleaned using soap and warm water. If this isn’t sufcient, 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 nish.
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 is recommended every 90 days. In some instances, you
may nd 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 specically 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.
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.
In order to maintain proper refrigeration performance, the condenser ns 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 con-
tains 12-30% chromium which forms an invisible passive lm 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 lm is broken or
contaminated, outside elements can begin to breakdown the steel and begin to form rust of discoloration.

MAINTENANCE (CONTINUED)
Proper cleaning of stainless steel requires soft cloths or plastic scouring pads,
NEVER USE STEEL PADS, WIRE BRUSHES OR SCRAPERS!
Cleaning solutions need to be alkaline based or non-chloride based. Any cleaner containing chlorides will
damage the protective lm of the stainless steel. Chlorides are also 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 nish of the steels
protective layer.
Early signs of stainless steel breakdown can consist of small pits and cracks. If this has begun, clean thor-
oughly and start to apply stainless steel cleaners in attempt to restore the passivity of the steel.
Never use an acid based cleaning solution. Many food products have an acidic content which
can deteriorate the nish. Be sure to clean the stainless steel surfaces of ALL food products.
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 oor is not level this can also cause drain problems. Be sure
all drain lines are free of obstructions because this can cause water to back up and overow the drain pans.
