Caution:
Never expose your body directly to cool air for a long time. Excessive ex-
posure to cool air is bad for your health, and should therefore be avoided.
Dry operation
The dry is a microcomputer-controlled dehumidifying operation which controls
excessive air-cooling according to the room temperature of your choice. (Not us-
able for heating.)
1. Until reaching room temperature of your choice
The compressor and indoor fan function is linked motion according to the
change of the room temperature and automatically repeat ON/OFF.
2. When reaching room temperature of your choice
Both the compressor and indoor fan stop.
When stop continues for 10 minutes, the compressor and indoor fan are

Regarding displays during heating operation "DEFROST"
Displayed only during the defrosting operation.
"STAND BY"
Displayed from the start of heating operation until the moment warm air blows
out.
Caution:
• When the air-conditioner is used together with burners, thoroughly
ventilate the area. Insufficient ventilation can result in accidents due to
oxygen deficiency.
• Never place a burner at a place where it is exposed to the airflow from
the air-conditioner.
Doing so can result in imperfect combustion of the burner.
• The microcomputer functions in the following cases: *
• Air does not blow out when heating starts. *
- To prevent any cool air from escaping, the indoor fan is gradually switched
in sequence from faint airflow/weak airflow/set airflow according to the
temperature rise of the blown out air. Wait a moment until the airflow
comes out naturally.
• The fan is not moving at the set speed. *
- In some models, the system switches over to faint airflow when the tem-
per-ature of the room reaches the set temperature. In other cases, it stops
to prevent any cool air from escaping during the defrosting operation.
• Air flows out even if operation is stopped. *
- Approximately 1 minute after the stop of operation, the indoor fan some-
times rotates to eliminate extra heat generated by the electric heater, etc.
The fan speed comes to low or high.
* Except PEFY-P-NMHU-E-F.
