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)
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 "8. MAINTENANCE" on page 7.). (*2)
*1 The consumed power while the outdoor unit is not in
operation depends on the model.
*2 The setting before the power circuit breaker is cut off
is stored. (The timer setting is cleared.)
•
When the display shows "TIME TO CLEAN AIR FILTER"
ask a qualified service person to clean the filter
(Refer to "8. MAINTENANCE" on page 7.).
• 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 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
temperature.
We recommend starting the operation in advance using
timer operation.
