again turn off for an additional 30 sec and the outdoor fan for 40
sec. When the Quiet Shift is in OFF position, only a brief 30 sec
cycle will be observed.
If it is desirable to observe a complete defrost in warmer weather,
the defrost thermostat must be closed as follows.
1. Turn off power to outdoor unit.
2. Disconnect outdoor fan motor lead from OF2 on control board
(See Fig. 18). Tape to prevent grounding.
3. Restart unit in heating mode, allowing frost to accumulate on
outdoor coil.
4. After a few minutes in heating mode, liquid line temperature
should drop below closing point of defrost thermostat (ap-
proximately 30 degree F).
NOTE:
Unit will remain in defrost until defrost thermostat
reopens at approximately 80 degree F coil temperature at liquid
line or remainder of defrost cycle time.
5. Turn off power to outdoor and reconnect fan motor lead to
OF2 on control board after above forced defrost cycle.
