Observe the following precautions to ensure the
system operates.
•
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
decrease the effect of cooling and heating .
•
Never place objects near the air inlet and the air
outlet of the unit. It may deteriorate the effect or
stop the operation.
•
Adjust the room temperature properly for a com-
fortable environment. Avoid excessive heating or
cooling.
Not doing so wastes electricity.
•
When the display shows “
” or “Time to clean
filter”, ask a qualified service person to clean the
filters.
(Refer to “MAINTENANCE” on page 10.)
Operating the 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.
•
Turn off the power circuit breaker when it is not in
use for a long period (only for R410A refrigerant).
When the main power switch is turned on, small
amount of power is consumed even if the system
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
“MAINTENANCE” on page 10.) (*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
in the ceiling.
Set the air discharge to horizontal direction during
COOLING or PROGRAM DRY OPERATION, and
set it downwards during 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 TIMER OPERA-
TION.
