Operation

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.

Door Maintenance

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.

Defrosting

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.
