D. Defrost
DANGER
Risk of Fire or Explosion Flammable Refrigerant Used
• Do not use mechanical devices to defrost.
• Do not puncture refrigerant tubing. Risk of re or explosion due to puncture of
refrigerant tubing; follow handling instructions carefully.
Risque De Feu Ou D'Explosion Le Frigorigène Est Inammable
• Ne pas utiliser d'appareils mécaniques pour dégivrer le réfrigérateur.
• Ne pas perforer la tubulure contenant le frigorigène. Risque de feu ou d'explosion si la
tubulure contenant le frigorigène est perforée; suivre les instructions de manutention
avec soin.
1. Undercounter and Worktop Refrigerators
Off-Cycle Defrost: Undercounter and worktop refrigerators defrost naturally between run
cycles.
2. Prep Table Refrigerators and Undercounter and Worktop Freezers
Prep tables and freezers use a heated, time-initiated, temperature-terminated defrost.
• Prep tables have a defrost interval of 6 hours and freezers have a defrost interval of
8 hours. The defrost timer starts when power is supplied to the appliance.
The minimum defrost time is 5 min.
The maximum defrost time is 45 min. for prep tables and 1 hour for freezers.
• When the defrost thermistor warms to 46°F (7.7°C) on prep tables and 50°F (10°C)
on freezers, defrost terminates.
• On prep tables, the compressor energizes 1-min. after defrost heater de-energizes
(drip time) and the evaporator fan motor(s) energize 30-sec. after the compressor
energizes. Note that the 30-sec. evaporator fan motor delay time is a maximum;
ifthe defrost thermistor cools to 40°F (4.4°C) before the 30-sec. evaporator fan
motor delay timer terminates, the evaporator fan motor(s) will energize.
• On freezers, the compressor energizes 3-min. after defrost heater de-energizes
(drip time) and the evaporator fan motor(s) energize 4-min. after the compressor
energizes. Note that the 5-min. evaporator fan motor delay time is a maximum; ifthe
defrost thermistor cools to 25°F (-3.8°C) before the 5-min. evaporator fan motor
delay timer terminates, the evaporator fan motor(s) will energize.
To manually initiate or terminate a defrost cycle: Turn the cabinet temperature control
dial to 7, pause for 3 to 10 sec., then return the cabinet temperature control dial to any
position below 7. Defrost initiates or terminates within 5 sec.
Note: When defrost is manually initiated it continues through the normal defrost cycle
unless manually terminated.
