ing 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, room air will flow out and
cause to decrease the effect of cooling and heating.
• Do not place other heaters directly below the
indoor unit.
They may deform due to the heat.
• Never place objects near the air inlet and the air
outlet of the unit. It may cause deterioration in the

• 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 6hours before operation for smooth
running (Refer to MAINTENANCE).
• When the display shows “ ” (TIME TO CLEAN
AIR FILTER), ask a qualified service person to
clean the filters (Refer to MAINTENANCE).
• Fully use the function of air flow direction adjust.
Cold air gathers on the floor, and warm air gathers
in the ceiling.
Set the air flow direction parallel during cooling or
dry operation, and set it downwards during heat-

• It takes time for the room temperature to reach the
set temperature.
We recommend starting the operation in advance
using timer operation.
