the lights when opened.
1. Every 6 hours, the unit will turn off and to allow the evaporator coil to defrost. The
controller now displays defrost symbol. When the coil temperature reaches 41°F
or after 20 minutes of defrost, the unit will turn on again.
2. Anti-condensation heaters on door frames work in conjunction with the
compressor.
3. The factory setting for the temperature range is 34°F to 38° F.
Freezers:
During the refrigeration cycle, the controller supplies power to the
condensing unit and evaporator fan motors. The evaporator fans will run at any time
when the evaporator coil temperature is below 54°F. They will also keep running
when door is open but cycle off during a defrost period. The door switch will activate
the lights when opened.
1. Every 6 hours, the unit will turn off and electric heater will turn on to defrost. The
controller now displays the defrost symbol. When the coil temperature reaches
45°F or after 20 minutes of defrost, the unit will turn on again.
2. Anti-condensation heaters on door frames work in conjunction with the
compressor.
3. The factory setting for temperature range is -7 to -3°F
