FREEZER SYSTEM AND ADJUSTMENT
All self-contained value line and designer line standard freezers and low- temperature freezers are designed and factory set to maintain an average cabinet temperature of 0` f and -15`f respectively. All freezers are designed for the purpose of holding pre-frozen food and although they are capable of freezing small quantities of fresh food, they are not to be used as fast or blast freezers. Do not attempt to freeze bulk quantities of fresh foods. The temperature control is accessible from the top of the electrical console box located on the cabinet top behind the front grill (see figure 6).if an adjustment is necessary to maintain the above temperature range only on standard freezers, place a screwdriver into the thermostat slot and turn clockwise for a colder cabinet temperature or counterclockwise for a warmer cabinet temperature. On low-temperature freezers, place a screwdriver into the right thermostat adjustment screw (do not turn the left differential adjustment screw) and turn clockwise for a colder cabinet temperature or counterclockwise for a warmer cabinet temperature. Further adjustments out of the factory design temperature range must be made by a qualified refrigeration mechanic only.
DEFROST OPERATION
All freezer models are equipped with an automatic, electric defrost system consisting of an electric evaporator coil and drain pan heater, automatic electric defrost time clock, defrost high limit switch, and a fan delay switch. The defrost system is time initiated by the time clock and temperature terminated by the high limit switch. The time clock is factory preset for three (3) defrost periods per day at eight (8) hour intervals and a fail safe cut-off time of 32 minutes. These settings should be adequate for most conditions, however, depending upon use and climate conditions a fourth defrost may be required.
The defrost time clock is located in the electrical console box where a window allows access to the timer dial. To set the time of day on the defrost time clock, turn the knob on the center dial of timer face counterclockwise as the arrows indicate until the correct time of day is lined up with the "time" arrow on the upper left corner of the clock (see figure 8). It will be necessary to reset the time of day on the timer if the freezer is turned off or has loss of power. To relocate and/or add a defrost period, simply unscrew the defrost pins located around the outer dial and screw them into the desired time slots (an additional pin is located in a storage slot on the right side of the dial).
Important Note: All freezers have a unique, energy-saving defrost cycle. It is time initiated, temperature terminated, with an automatic, auxiliary time cut-off safety to minimize electrical consumption and provide for the shortest possible heating cycle. This safety time cut-off is factory set at 32 minutes and should not require any further adjustment.
