RECOMMENDATIONS COULD RESULT IN DAMAGE TO THE INTERIOR OF THE

REFRIGERATION CYCLE
REFRIGERATORS: During the refrigeration cycle, the evaporator fans wilt run
continuously even when one or more doors are open. The door switch will activate
the lights when opened. Every 6 hours, the unit will turn off to let the evaporator
coil clear up the ice. The controller now displays the defrost symbol. When the
coil temperature reaches 41°F or after 20 minutes of defrost, the unit will turn on
again. The factory setting of the temperature range is 34 to 38°F.
FREEZERS: During the refrigeration cycle, the controller supplies power to the
condensing unit and evaporator fan motors. The evaporator fan will run at any time
when the evaporator coil temperature is below 54°F and it will cycle off during
the defrost period. Every 6 hours, the unit will turn off and the defrost heater will
work to clear up the ice. 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. Anti-Condensation heaters on the door frames work in conjunction with
the compressor. The factory setting of the temperature range is -7 to -3°F
