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
airflow 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.
Prevent any obstruction from blocking the outlet or inlet of airflow.
Outside Cabinet
Be sure that the unit has adequate air circulation around it. 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
Levelling the cabinet is necessary so that 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
to place. Failure to meet this requirement can cause compressor failure and
unit damage.
Warranty Repairs will be declined if problems are caused by improper
installation.
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.
- 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 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,
NEVER USE STEEL PADS, WIRE BRUSHES OR SCRAPERS!
DANGER
- 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.
- CAUTION 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.
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.
