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.
RECEIVINGAND 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. 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.

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. 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 required that the unit be installed no closer than 3" from any wall including the back 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. 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, ease of cleaning underneath and for mobility.
Casters are mounted using 3 bolts in each. 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.All models must be on a dedicated 20 amp circuit. Units
using a shared electrical circuit or outlet maynot be subject to standard unit warranties. Use of extension
cords is prohibited and will immediately void the unit warranty.
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, tryammonia and
water or a nonabrasive liquid cleaner.

Do not use an abrasive cleaner because it will scratch the paint 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 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 procedureswill 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.
NEVERUSE STEEL PADS, WIRE BRUSHES OR SCRAPERS!
MAINTENANCE
Cleaning solutions need to be alkaline based or non-chloride based. 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 exterior can be done with soap and water. Extreme stains or greaseshould 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 steels protective layer.
Never use an acid based cleaning solution！Many food products have an acidic content
which can deteriorate the finish. Be sure to clean the 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

ServiceandInstallationManual

sharp tools or knives to scrape or cleanthe gasket which could possiblytear thegasket 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 can cause water to back up and overflow the drain pans.
Warranty service calls for water issues that are not a result of manufacturing issue will not be covered
and will be responsibility of customer.
