NOTE
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 efcient 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 overow 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 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.

DANGER
REFRIGERATORS AND FREEZERS
The interior and exterior can be cleaned using soap and warm water. If this isn’t sufcient, 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 at least 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 specically
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.
cleaning the refrigerated area.
Never use a high pressure water wash for this cleaning procedure
as water can damage the electrical components located near or
DANGER
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
commercially available 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, it is
important 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 lm over the steel’s 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.
at the condenser coil.
Proper cleaning of stainless steel requires soft cloths or plastic

scouring pads. NEVER USE STEEL PADS, WIRE BRUSHES OR SCRAPERS!
SERVICE AND INSTALLATION MANUAL
CAUTION
DANGER

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
thoroughly 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.
Also, never 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 do not require the use of tools or authorized service persons.
The gaskets are “Dart” style and can be pulled out of the grove in the door and new gaskets can be
“pressed” 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 overow the drain pans.
