Defrost
Frost gradually builds-up on evaporator coils as a result of normal operation. The unit uses hot refrigerant to defrost the evaporator coil. Hot refrigerant gas passes through the evaporator coil and melts the frost. The water flows through collection drain tubes onto the ground. The methods of defrost initiation are Automatic and Manual.
Manual Defrost: In Manual Defrost mode, the operator initiates a defrost cycle.
Note The unit will not perform a Manual
Defrost Cycle unless the unit has been turned on with the ON key,
the unit is running in Continuous or CYCLE-SENTRY Mode (or shut down
in CYCLE-SENTRY Null Mode), and the coil temperature is below 7°C (45°F).
