• The fan operation functions to circulate the air in the room.
• The temperature of the room cannot be set by fan operation.
Caution:
Never expose your body directly to cool air for a long time. Excessive expo-
sure 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 ex-
cessive air-cooling according to the room temperature of your choice. (Not usable
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.

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 venti-
late the area. Insufficient ventilation can result in accidents due to oxy-
gen 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 tempera-
ture 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 temper-
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.
