Recommended airflow direction positions
We recommend using the airflow in the position
listed above when fixing the airflow direction.
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 " " or "Time to clean
filter", ask a qualified service person to clean the
filters.
(Refer to "
MAINTENANCE (FOR SERVICE
PERSONNEL) " on page 8.)
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.
• 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 "
MAINTENANCE (FOR SERVICE
PERSONNEL) " on page 8) (*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.
Cooling
Heating
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.
8. MAINTENANCE
(FOR SERVICE PERSONNEL)
ONLY A QUALIFIED SERVICE PERSON IS
ALLOWED TO PERFORM MAINTENANCE
WARNING
• Do not use flammable gas (such as hair
sprays and insecticides) near the air
conditioner.
• Do not wipe the air conditioner with benzine or
thinner.
It may cause cracks, electric shocks or a fire.
• Never put your fingers or rods in the air inlet,
air outlet or horizontal blade. The fan is
rotating at high speed, so you would get
injured.
CAUTION
• Do not wash the air conditioner with water.
It may cause electric shocks or a fire due to
leakage.
• Make sure to turn off the air conditioner when
taking care of the air conditioner and
disconnect the power supply breaker.
Unless the power supply is disconnected, it
may cause electric shocks and injuries.
• When working at a high place, give caution to
your footing.
If the scaffold is unstable, it may cause
injuries due to fall and stumbling.
NOTE
• Do not remove the air filter unless for
cleaning. It may cause failure.
• Do not attach substance (such as paper
towels) other than the specified air filter to the
air inlet. The performance may drop and
cause freeze-up/water leakage.
