INSTALLATION
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.
Stabilizing
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.
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 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.
• For efficient operation, keep the condenser surface free of dust, dirt, and lint.
• We recommend cleaning the condenser coil at least once per month.
• Clean the condenser with a commercial condenser coil cleaner and a soft brush, available from any
commercial refrigeration equipment retailer, or vacuuming the condenser with a shop vac or use CO2.
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 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.

Service and Installation Manual

MAINTENANCE
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 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.
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.
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.
