7. OPTIMUM OPERATION

Observe the following precautions to ensure the
system operates.
• Adjust the room temperature properly for a com-
fortable environment. Avoid excessive heating or
cooling.
• Prevent direct sunlight from entering a room dur-
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.

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 6hours before operation for smooth
