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.

After the unit is connected to power it will automatically begin 

operating. With the doors closed, the temperature of the 

cabinet should reach 0°F (-18°C) on freezers 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 -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.
When the mechanical timer initiates a defrost cycle, 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.
