Efficient Use
6 EFFICIENT USE
6.1 EFFICIENT USE OF INDOOR UNIT
•
Do not leave a window or a door open.
The operating efficiency will be decreased.
It may cause dew condensation of the indoor unit. (Ventilate
a room sufficiently too.)
•
Attach a curtain or a blind to a window.
Direct sunlight is prevented and the cooling efficiency will be
increased.
•
Do not use heating appliances during the cooling operation
as possible.
6.2 EFFICIENT USE OF COOLING AND HEATING
1 Air flow direction: the appropriate air outlet angle is approx
Aº. If the cooling is not sufficient, change the air flow
direction. Pay attention to dew drop which may occur due to
the long cooling operation with low louver angle.

2 Air flow volume: "MED" should be usually used. If the air
flow volume is set as "HIGH", the air flow will be spread
wider than "MED".
3 Temperature: the recommended set temperature is 26 to
28ºC. If the cooling is not sufficient, set the lower temperature

About Multi-Split system
When the number of indoor unit or the operating mode is changed, the
air outlet temperature may be changed and the indoor temperature is
changed. In this case, set as follows.
•
During cooling: lower slightly the temperature setting.
•
During heating: raise slightly the temperature setting.

The cooling efficiency will be decreased. It may cause dew
condensation and dropping dew.
•
Use a circulator if warm air stays around ceiling.
The comfortability will be increased. Contact your distributor
for the detail.
•
Turn OFF the main power source if the indoor unit is not
used for a long time.
If not, the standby electricity charges will have to be paid
even if the indoor unit is unused.

8.1 RECOMMENDED AIR FLOW DIRECTION SETTING"
The louver angle is changed automatically during the heating
operation.

When the heating operation starts
•
When the defrost operation starts
When the discharge temperature is higher than 30ºC, the louver
angle is automatically returned to the setting condition.
