Airflow has stopped to prevent blowing out of cold air until the indoor
heat exchanger has warmed up. (2 to 5 min.) (HOT KEEP program)
When outdoor temperature is low and humidity is high, the unit some-
times performs defrosting automatically. Please wait. During defrost-
ing, water or steam may escape from the outdoor unit.
Airflow is not blown out when starting the DRY operation.
(RUN light is on)
The indoor fan may stop to prevent re-evaporation of dehumified
moisture and to save energy.
Some steam escapes during COOL operation.
This may occur if the room's temperature and humidity are very high.
It disappears as soon as the temperature and humidity decrease.
Restart is blocked for 3 minutes after you have stopped the operation
to protect the unit.
The three-minute protection timer in the microcomputer automatically
starts it up again.
Please wait for
three minutes.
