Stopping the system

6

Press the ON/OFF button once again. 

 

The operation lamp goes off and the system 
stops operation.

NOTICE

•  Do not turn off the power immediately 

after the unit stops, but wait for at least 

 

5 minutes.

•  The system need at least 5 minutes for 

residual operation of drain pump device. 
Turning off the power immediately will 
cause water leak or trouble.

Explanation of heating operation

It may take longer to reach the set temperature for 
general heating operation than for cooling operation.
The following operation is performed in order to 
prevent the heating capacity from dropping or cold 
air from blowing.

Defrost operation

•  In heating operation, freezing of the outdoor 

unit’s air cooled coil increases over time, 
restricting the energy transfer to the outdoor 
unit’s coil. Heating capability decreases and the 
system needs to go into defrost operation to be 
able to deliver enough heat to the indoor units:

•  When an outdoor unit is operating defrost, 

 

the indoor unit will stop fan operation, the 
refrigerant cycle will reverse and energy from 
inside the building will be used to defrost the 
outdoor unit coil.

•  The indoor unit will indicate defrost operation on 

the displays “ 

 ”.

Hot start

In order to prevent cold air from blowing out of an 
indoor unit at the start of heating operation, the 
indoor fan is automatically stopped. The display of 
the user interface shows “ 

 ”.  

It may take some time before the fan starts. This is 
not a malfunction.

INFORMATION

•  The heating capacity drops when the 

outside temperature falls. If this happens, 
use another heating device together with 
the unit. (When using together with 
appliances that produce open fire, 
ventilate the room constantly). 

 

Do not place appliances that produce 
open fire in places exposed to the air flow 
from the unit or under the unit.

•  It takes some time to heat up the room 

from the time the unit is started since the 
unit uses a hot-air circulating system to 
heat the entire room.

•  If the hot air rises to the ceiling, leaving 

the area above the floor cold, we 
recommend that you use the circulator 
(the indoor fan for circulating air). Contact 
your dealer for details.

6.2 

Program dry operation

•  The function of this program is to decrease the 

humidity in your room with minimal temperature 
decrease (minimal room cooling).

•  The microcomputer automatically determines 

temperature and fan speed 

 

(cannot be set by the user interface).

•  The system does not go into operation if the 

room temperature is low (<20°C).
