OPERATION

Refrigerated Cabinets

After the cabinet is connected to the power source it will automatically begin operating. With the covers and doors closed, the temperature of the cabinet should reach 36°F to 40°F (2°C to 4°C) in about one hour. Temperature on salad top will maintain 33°F to 41°F (1°C to 4°C) with pans recessed 2.5” (6.5cm) at 86°F ambient room temperature for a period of four hours, meeting NSF-7 requirements. The temperature control on a flat top unit is located on the back panel inside the refrigerator and can be adjusted to meet the current conditions. The temperature control on a salad top unit is located in the rear of the unit, 14" to 16" above floor in access hole.

Refrigerated cabinets with two evaporators have counter-rotating fans to ensure even airflow throughout the cabinet. The left evaporator has a CCW motor and a clear fan blade and right evaporator has a CW motor and a black fan blade.

Temperature Control Instruction for Flat Top Units

A thermostat located in the evaporator housing on the interior rear of the cabinet controls the temperature inside the box (see Figure 4). The factory setting for the control is “4” and maintains about 38°F (3°C) inside the box. Set toward “1” for higher temperatures and toward “7” for lower temperatures.

Temperature Control Instruction for Salad Top Units

A thermostat located in rear of cabinet controls the temperature inside the box (see Figure 5). The factory setting for the control is 5 and maintains about 34°F(1°C) to 36°F (2°C) inside the box. Set toward 1 for higher temperatures and toward 9 for lower temperatures.

CAUTION

Cabinets with pans should be operated with pans in place. Operating the cabinet without all pans in place will lessen efficiency and may damage the cabinet.

Continuous opening and closing of the door will hamper the cabinet’s ability to maintain optimum refrigeration temperature.

Top section is not intended for overnight storage. Product should be removed from pans. Pans can remain in cabinet while empty.

Defrosting

Refrigerators defrost automatically with every cycle of the compressor. The water generated is routed to a pan on the rear of the cabinet and is evaporated by the heat given off by the compressor.
