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 refrigerator 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.
Prevent obstruction by locating large boxes and tall stacks of product to the bottom of the cabinet.
Outside cabinet:
Be sure that theunit has access to ample air. Avoidhot corners and locations near stoves and ovens.
It is recommended that the unit beinstalled no closer than 6" from any wall with at least 12" ofclear space above
the unit. Should it become necessary 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 requirement can
cause compressor failure and unit damage.
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 contents 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. Because the unit is supplied with
casters, no adjustments are available. Ensure the floor where the unit is to be located is level.
Stabilizing
Models are supplied on casters for your convenience, ease of cleaning underneath 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.
Standard warranties will be voided due toimproper 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. A protected circuit of the correct voltage and amperage must
be run for connection of the line cord or permanent connection to the unit.
The ON/OFF switch must be turnedto OFF and the unit disconnected from
the power source whenever performing service, maintenancefunctions or
cleaning the refrigerated area.

OPERATION
Do not throw items into the storage area. Failure to heed these recommendations could result in
damage to the interior of the cabinet.
Refrigeration cycle
Refrigerators:Every 6 hours, the unit will shut off to allow the evaporator coil to defrost and the controller will
display the defrost symbol. When the coil temperature reaches 41°F or after 20 minutes, the unit returns to the
refrigeration cycle.The factory setting for temperature range is 34° to 38°F.
Freezers: During the refrigeration cycle the controller supplies power to the condensing unit and evaporator fan
motors. The evaporator fans will run at any time when the evaporator coil temperature is below 54°F andthey will
cycle off during defrost period. Every 6 hours, the unit will shut off and the defrost heater will defrost the
evaporator coil and the controller will display the defrost symbol. When the coil temperature reaches 45°F or
after 20 minutes, the unit returns to the refrigeration cycle.
1. Anti-Condensation heaters on the door frames work in conjunction with the compressor.
2. The factory setting for temperature range is -7°F to -3°F.
On/Off Switch:
An on/off switch is located on the front of the bottom shroud. When the unit is on, the switch will glow green.
Light Switch:
A light switch is located next to on/off switch on the front of the bottom shroud.
