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.
• 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.
• 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.
• Install TVS, radios, and stereos 1 m or more away from
the indoor unit and remote controller.
Images may become fuzzy and noise may be generated.
• 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. (*1)

Cold air gathers on the floor, and warm air gathers in the
ceiling.
Set the air direction to horizontal during the COOLING or
PROGRAM DRY OPERATION, and set it downwards
during the HEATING OPERATION.
Do not let the air blow directly to a person.
• It takes time for the room temperature to reach the set
