OPTIMUM OPERATION

Observe the following precautions to ensure the system oper-
ates.
• 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, 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 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 supply
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).
• When the display shows "
FILTER), ask a qualified service person to clean the filter
(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 heating operation.
Do not let the air blow directly to a person.
• It takes time for the room temperature to reach the set tem-
perature.
We recommend starting the operation in advance using
timer operation.

• Only a qualified person is allowed to perform mainte-
nance without daily maintenance.
• Before touching any of connection wirings, be sure to
turn off all power supply switches.
