If the doors are out of alignment on the cabinet, the doors can be adjusted. This can be
accomplished by opening the door(s) and loosening the screws that hold both the top and
bottom hinges to the cabinet. After adjusting the door so that it is aligned correctly, tighten
the screws to securely hold the hinges in place.
ELECTRICAL
Check the proposed outlet to be used to insure that the voltage, phase and current carrying
capacity of the circuit from the electrical panel correspond to the requirements of the
cabinet. NEVER use an extension cord to wire any unit. On permanently connected units,
those not furnished with a plug-in service cord, all inter-wiring between the electrical panel
and the unit must be done in accordance with the National Electric Code and all state and
local codes. Refer to the serial tag for all pertinent electrical information.
Observe all Warning Labels. Disconnect power supply to eliminate injury from
electrical shock or moving parts when servicing equipment.
GENERAL OPERATION
The refrigerators and freezers employ a unit cooler evaporator located outside the cabinet
as the heat removing source. Through the refrigeration process, heat is captured in the
evaporator, transferred to the condensing unit on top of the cabinet, and expelled to the
surrounding outside air. It is extremely important to allow a four (4) inch clearance on the
top, rear, and sides of the unit for the refrigeration process to function properly.
These refrigerators and freezers utilize a programmable controller to control the
temperature and defrost settings. The controller, which is located on the facade of
the unit, is factory set. Please see the default settings sheet and separate
instructions that are included on the operation of this controller.
REFRIGERATORS
During the operation of a refrigerator unit, frost will periodically form on the coil surface.
Each time the compressor cycles "off", the evaporator fans will continue to run, which will
keep the internal temperature uniform and at the same time remove any frost build up on
the coil. The water produced will collect in the unit cooler drain pan and travel down the
drain tube to the condensate vaporizer.
FREEZERS
After shutting the door on freezer models, a short amount of time must be allowed before
the door can be reopened. This is due to the tight seal maintained between the door and
the cabinet. Waiting a few moments for the pressure to equalize permits the door to be
opened easily.
A positive defrost is required to remove frost from the coil in freezer models. This is
accomplished by energizing heaters during the defrost cycle that are positioned on the coil
surface. The programmable controller is factory set to allow four defrosts per day.
