3. Adjust Air Flow Direction from the Main Menu.
• If the connected indoor unit model does not include
oscillating louvers this function will not be available.
4. When the On/Off Button is pressed again, the system will
stop operating and the operation lamp will turn off.
NOTE: To prevent water damage or system failure, do not
immediately remove power from the indoor unit following
system operation. Wait at least five minutes for the condensate
pump to finish draining residual water from the unit.
CHARACTERISTIC OF DRY MODE
The Dry Mode dehumidifies the space at reduced cooling capacity
to prevent the room temperature from dropping to uncomfortable
levels.

7. OPTIMUM OPERATION

Observe the following precautions to ensure the system operates:
• Adjust the room temperature properly for a comfortable
environment. Avoid excessive heating or cooling.
• Prevent direct sunlight from entering a room during cooling
operation by using curtains or blinds. Ventilate the room
regularly. Using the unit for long periods of time requires
attentive ventilation of the room.
• Keep doors and windows closed. If the doors and windows
remain open, air will escape and diminish cooling or heating
operation.
• Never place objects near the air inlet and the air outlet of the
unit. It may cause deterioration in the effect or stop in the
operation.
• Turn off the main power supply switch when it is not used for
long periods of time. When the main power switch is turned
on, some watts of electricity is being used even if the system
is not operating. Turn off the main power supply switch for
saving energy. When reoperating, turn on the main power
supply switch 6 hours before operation for smooth running
(Refer to MAINTENANCE).
English
• When the display shows "Time to clean filter'', ask a qualified
service person to clean the filters (Refer to MAINTENANCE).

8. MAINTENANCE (FOR SERVICE PERSONNEL)

• Only a qualified person is allowed to perform
maintenance without daily maintenance.
• Before touching any of the connection wirings, be sure
to turn off all power supply switches.
• For installation of optional parts, only a qualifited person
is allowed to do so.
Be sure to use optional parts specified by the manufacturer.
Installation in your own manner may result in water leakage,
electric shock or fire.
• Do not use flammable material (e.g. hair-spray or insecticide)
near the product.
• Only proceed with the unit cleaning after stopping the
operation and turning the power supply off.
Failure to do so may result in electric shocks or injury.
• Do not wash the heat pump or air handler with water.

inside of the air handler.
Wrong cleaning procedures may break plastic parts or cause
water leakage or electric shock.

season when cooling or heating is required, clean the air
conditioner or heat pump.)
• If the area around the indoor unit is very dusty, use a dust
proof cover (local procurement).
