CHARACTERISTICS OF THE HEATING 

OPERATION (HEATING OPERATION AND 

AUTOMATIC HEATING OPERATION)

START OF OPERATION

It generally takes a longer time for indoor 
temperature of the HEATING OPERATION to 
reach the set temperature compared to the 
COOLING OPERATION. It is advisable to start 

 

capacity decrease and discharge of cool air.

AT THE START OF OPERATION AND AFTER 

THE DEFROST OPERATION

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.

The 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.
(The remote controller displays the fan speed that 
is set.)

The airflow direction becomes horizontal to 
prevent a draft of cool air to the inhabitants.
(The remote controller displays the airflow 
direction that is set.)

DEFROST OPERATION

(Frost removal operation for the outdoor 

unit)

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

The indoor unit fan stops and the remote 
controller display shows “           ”.
With the wireless remote controller, the warm air 
stops, and the DEFROST OPERATION lamp on 
the light receiving unit turn on. (The remote 
controller displays the fan speed that is set.)

After maximum 10 minutes of the DEFROST 
OPERATION, the air conditioner returns to the 
HEATING OPERATION.

The airflow direction becomes horizontal. (The 
remote controller displays the airflow direction 
that is set.)

During or after the DEFROST OPERATION, white 
mist comes out from the air inlet or outlet of the air 
conditioner.
(Refer to “

4.

” on page 14.)

A hissing and “Shuh” sound may be heard during 
this particular operation.

Regarding outside air temperature and 

heating capacity

The heating capacity of the air conditioner 
declines as the outside air temperature falls. 
In such a case, use the air conditioner in 
combination with other heating systems.
(When a combustion appliance is used, ventilate 
the room regularly.)
Do not use the combustion appliance where the air 
from the air conditioner is blown directly toward it.

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 local dealer.

When the indoor temperature exceeds the set 
temperature, the indoor unit discharges a gentle 
breeze (switches to gentle wind). The airflow 
direction becomes horizontal. (The remote 
controller displays the fan speed and airflow  
direction that are set.)

CHARACTERISTICS OF THE PROGRAM 

DRY OPERATION

This operation lowers the humidity without 
lowering the indoor temperature. The indoor 
temperature when the operation button is pressed
will be the set temperature. At this time, the fan 
speed and temperature are set automatically, so 
the remote controller does not display the fan 
speed and set temperature.
To efficiently lower the indoor temperature and 
humidity, first use the COOLING OPERATION to 
lower the indoor temperature, and then use the 
PROGRAM DRY OPERATION. When the indoor 
temperature is lowered, airflow from the air 
conditioner may stop.

When operating continuously at downward airflow 
direction, air blows in the automatically set 
direction for a period of time to prevent condensation
on the horizontal blade. (The remote controller 
displays the airflow direction that is set.)

If the PROGRAM DRY OPERATION is used when 
the indoor temperature is low, frost forms the heat 
exchanger of the indoor unit. In this case, the air 
conditioner automatically switches to the 
DEFROST OPERATION for a while.
The low fan speed or a gentle wind is used to 
prevent the discharge of melt water.

operation in advance using the TIMER OPERATION.

Perform the following operation to prevent heating
