COOLING
HEATING
1
Air flow direction: the appropriate air outlet angle is approx.
35º. 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 louvre angle.

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.
5 MAINTENANCE
!
D A N G E R
•
Turn OFF the power source before the maintenance work. If not, it may cause a fire or an electric shock.
•
Perform the maintenance work with stable footing. If not, it may cause falling or injury.
!
C A U T I O N
Hold the air filter and the air inlet grille securely by hand when opening, closing, attaching or removing them. If not, it may cause the product falling,
resulting in an injury.
?
N O T E
Do not operate the system without the air filter, to prevent the indoor unit heat exchanger from being clogged.
