grounded.The
appliance should always be plugged intoitsownindividualelectricaloutletwhichhasa voltagerating
that matchestheratinglabelon the appliance. This provides the best performance and also prevents overloading

RECEIVING AND 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 formally reported to the
delivering carrier as soon as possible within 10 days.
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.

APPLIANCE INSTALLATION
Remove Packaging Materials
IMPORTANT:
Do not remove any permanent instruction labels or the data label on your appliance.
•Remove tape and glue from your appliance before using.
•To remove any remaining tape or glue, rub the area briskly with your thumb. Tape or glue residue can also be
easily removed by rubbing a small amount of liquid dish soap over the adhesive with your fingers. Wipe with
warm water and dry with a soft cloth.
•Do not use sharp instruments, rubbing alcohol, flammable fluids, or abrasive cleaners to remove tape or glue.
These products can damage the surface of your appliance.
NOTICE:
LOSS OR SPOILAGE OF PRODUCTS IN YOUR APPLIANCE IS NOT COVERED BY WARRANTY. IN ADDITION TO
FOLLOWING RECOMMENDED INSTALLATION PROCEDURES. PLEASE RUN THE APPLIANCE 24 HOURS PRIOR
TO USAGE.
Location Requirements
•Appliances 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 as a fully
loaded unit can weigh as much as 800 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" (51mm) from any wall, and a max door swing clearance of
60.5 in (1537mm).
WARNING
Excessive Weight Hazard
Use two or more persons to move and install appliances.
Failure to do so may result in back or other injury.
