AUTOMATIC DEFROST
UPRIGHT REFRIGERATOR - R600A
DEFROST CONTROL
The defrost period will vary dependent on the heater on time, with a maxi-
mum of 60 minutes. There is a 4 minute idle (drip time) time after the heater
turns off before the evaporator fan and compressor will turn on. During the
defrosting period a temperature sensor monitors the evaporator temperature
and the main control board turns the defrost heater off after the frost on the
evaporator has melted.
A manual defrost can be activated by simultaneously pressing and holding
+
and
AIR FILTER

a few seconds indicating manual defrost is activated. A beep will be heard,
and then the unit will display the last set point. There may be up to a 3 minute
delay before the defrost heater is energized.
Specifications subject to change without notice. For complete perfor-
mance data by model, refer to service manual. Options shown are not
