NOTE

• Do not place appliances which produce open fire 

in places exposed to the air flow from or under the 
indoor unit.

• It takes some time for the room to warm up from 

the time the unit is started since the unit uses a 
hot-air circulatory system to warm the entire 
room.

• If the hot air rises to the ceiling, leaving the area 

above the floor cold, we recommend using the cir-
culator (the indoor fan for circulating air). Contact 
your dealer for details.

PROGRAM DRY OPERATION

• The function of this operation is to decrease the 

humidity in your room with a minimum tempera-
ture decrease.

• The microcomputer automatically determines 

temperature and fan speed.

• The system does not go into the operation if the 

room temperature is low.

• The microcomputer automatically controls the 

temperature and fan speed, so these cannot be 
set by using the remote controller.

• This function is not available if the room tempera-

ture is 20°C or lower.
