DRY OPERATION.................................. “

The function of this program is to decrease the 
humidity in your room with the minimum tem-
perature decrease.

Micro computer automatically determines 
TEMPERATURE and FAN SPEED.

This system does not go into operation if the 
room temperature is below 16°C.

 Refer to figure 3 on page [1] 

For cooling only type, “COOLING”, “FAN” and 
“DRY” operation are able to select.

 ON/OFF

Press ON/OFF button

OPERATION lamp lights up or goes off and the sys-
tem starts or stops OPERATION.

[EXPLANATION OF HEATING OPERATION]

DEFROST OPERATION

As the frost on the coil of an outdoor unit increase, 
heating effect decreases and the system goes 
into DEFROST OPERATION.

The indoor unit fan stops and the remote control-
ler display shows “

”.

After 6 to 8 minutes (maximum 10 minutes) of 
DEFROST OPERATION, the system returns to 
HEATING OPERATION.

Regarding outside air temperature and heat-
ing capacity

The heating capacity of the air conditioner 
declines as the outside air temperature falls. In 
such a case, use the air conditioner in combina-
tion with other heating systems.

A warm air circulating system is employed, and 
therefore it takes some time until the entire room 
is warmed up after the start of operation.

An indoor fan runs to discharge a gentle wind 
automatically until the temperature inside the air 
conditioner reaches a certain level. At this time, 
the remote controller displays “

”. Leave it 

as it stands and wait for a while.

When the warm air stays under the ceiling and 
your feet are cold, we recommend that you use a 
circulator (a fan to circulate the air inside the 
room). For details, consult your dealer.

For programming TEMPERATURE and FAN 
SPEED, follow the procedure shown below.
