SERIAL NUMBER INF RMATI N
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.
RECEIVING AND INSPECTING THE
EQUIPMENT
Use care 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 con-
cealed 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.

Location:
Units represented in this manual are intended for indoor use only. Be sure the loca-
tion 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 dis-
charged 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. bstructions 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 broug ht 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.
utside 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 clearance above the unit.
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 con-
tents 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. If the unit is supplied with casters, it
has already been leveled. Ensure the floor where the unit is to be located is level.
Stabilizing:
All models are supplied with casters for your convenience, ease of cleaning under-
neath 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 neces-
sary 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 re-
quirement can cause compressor failure and unit damage.

MAINTENANCE
Refrigerators and Freezers
The interior and exterior can be cleaned using soap and warm water. If this isn't suffi-
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 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, at least every 90 days. In some in-
stances though 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 con-
The power switch must be turned to OFF and the unit discon›
nected from the power source whenever performing service,
maintenance functions or cleaning the refrigerated area.

Stainless Steel Care and Cleaning
To prevent discoloration of rust on stainless steel several important steps need to be
taken. Stainless steel contains 70-80% iron which will rust. It also contains 12-30%
chromium which forms an invisible passive film over the 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 break down 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 cleaners. Any cleaner
containing chlorides will damage the protective film 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 repeatedly and dry thor-
oughly upon completion.
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
Never use a high pressure water wash for this cleaning pro›

cated near or at the condenser coil.
NEVER USE STEEL PADS, WIRE BRUSHES OR SCRAPERS!
denser coil.If heavy grease is present there are de-greasing agents available for re-
frigeration use and specifically for the condenser coils. The condenser coil may re-
quire 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 com-
pressor.
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 con-
denser with a vacuum cleaner or stiff brush. If extremely dirty, a commercially avail-
able condenser cleaner may be required.

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 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 re-
store 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. Also, never use sharp tools or knives to
scrape or clean the gasket which could possibly tear the gasket and rip the bel-
lows.Gaskets can easily be replaced and do not require the use of tools or author-
ized 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
ver time and with heavy use doors the hinges may become loose. If it is noticed
that the door is beginning to sag, it may become necessary to tighten the screws
that mount the hinge brackets to the frame of the unit. If the doors are loose or sag-
ging this can cause the hinge to pull out of the frame which may damage both the
doors and the door hinges. In some cases this can require qualified service agents or
maintenance personnel.
Drain Maintenance
Each unit has a drain located inside the unit which removes the condensation from
the evaporator coil and evaporates it at 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 is collected underneath the unit you may want to check the conden-
sate evaporator drain tube to be sure it is still located inside the drain pan. The level-
ing 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 typically food product is found blocking drain lines caus-
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.
