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
in about one hour.
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.
Continuous opening and closing of the doors will hamper the
unit’s ability to maintain optimum refrigeration temperature.
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.
Service Alert
During normal operation the evaporator fan may cycle
and/or pulse independently of the compressor. Consult
the service manual or contact Technical Support at
1-888-732-2446 if you are unsure of the proper function.
