After the unit is connected to power it will automatically begin
operating. With the doors closed, the temperature of the
cabinet should reach 36°F to 40°F (2°C to 4°C) on refrigerators
or 0°F (-18°C) on freezers in about one hour.
Temperature control instruction
Refrigerators: A thermostat located in the evaporator housing
on interior rear of the unit, controls the temperature in the box.
The factory setting for the control is “4” and maintains about
38°F (3°C) in the box. Set toward “1” for higher temperatures
and toward “7” for lower temperatures.
Freezers: A thermostat located in the evaporator housing on
interior rear of the unit, controls the temperature in the box.
The factory setting for the control is “4” and maintains about -
3°F (-18°C) in the box. Set toward “1” for higher temperatures
and toward “7” for lower temperatures.
Continuous opening and closing of the doors will hamper the
unit’s ability to maintain optimum refrigeration temperature.

Adjusting door hinges
Doors have been adjusted at the factory. If it becomes
necessary to adjust a door, follow these instructions:
1) If the door needs lowering at the handle, use a 5/16” wrench
to loosen the hinge screws and install a spacer outside of
the hinge (see illustration 1). Tighten the screws.
2) If the door needs to be higher at the handle, use a 5/16”
wrench to loosen the hinge screws and install a spacer
inside of the hinge (see illustration 2). Tighten the screws.
Refrigerators
Refrigerators defrost automatically with every cycle of the
compressor. The water generated is routed to a pan on the
rear of the unit and is evaporated by the heat given off by the
compressor.
Freezers
When defrost control goes into defrost, power to the condensing
unit and evaporator fans is interrupted and the defrost heater
is energized. The defrost heater warms the evaporator coil
thereby melting all frost accumulated during the previous
refrigeration cycle. Once all frost is eliminated, the temperature
of the coil continues to rise until it reaches 27 minutes. The
defrost control switches to refrigeration mode. Defrost will
initiate every six hours.
Turn the screw ONLY in a clockwise direction,
turning the screw counter-clockwise will break
the cam motor.
