7. OPTIMUM OPERATION

Observe the following precautions to ensure the air
conditioner operates.
• Prevent direct sunlight from the window by using
curtains or blinds during the COOLING
OPERATION.
• Keep doors and windows closed. If the doors and
windows remain open, room air will flow out and
decrease the effect of cooling and heating.
• Never place objects near the air inlet and the air
outlet of the air conditioner. It may decrease the
effect or stop the operation.
• Adjust the room temperature properly for a
comfortable environment. Avoid excessive
heating or cooling.
Not doing so wastes electricity.
• When the display shows "
filter", ask a qualified service person to clean the
filters.
(Refer to "8. MAINTENANCE" on page 9.)
Operating the indoor unit with stained air filter
may decrease capacity or cause malfunction.
• 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.

" or "Time to clean
• Turn off the power circuit breaker when it is not
in use for a long period. When the power circuit
breaker is turned on, small amount of power is
consumed even if the air conditioner is not in
operation. (*1)
Turn off the power circuit breaker for saving
energy. When reoperating, turn on the power
circuit breaker 6 hours before operation for
smooth running.
(Refer to "8. MAINTENANCE" on page 9.) (*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.)
• Fully use the function of airflow direction adjust.
Cold air gathers on the floor, and warm air
gathers under 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.
• Use the TIMER OPERATION effectively.
It takes some time until the indoor temperature
reaches the set temperature. It is advisable to
start operation in advance using the TIMER
OPERATION.
