Optimum Operation; Maintenance (For Service Personnel) - Daikin FAA71AUVEB Operation Manual

7. OPTIMUM OPERATION

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 "
filter", ask a qualified service person to clean the
filters.
(Refer to "MAINTENANCE" on page 9.)
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. When the power circuit
breaker 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 cir-
cuit breaker 6 hours before operation for smooth
running.
(Refer to "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
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.

WARNING
• Do not use flammable gas (such as hair sprays
and insecticides) near the air conditioner.
Do not wipe the indoor unit with benzine or thin-

This may cause cracking, electric shock, or fire.
CAUTION
• Do not wash the air conditioner with water.
Doing so may result in an electric shock and fire.
• To clean the air conditioner, be sure to stop oper-
ation, and turn the power circuit breaker off. It may
cause electric shock or injury.
• Be careful of your footing when working at high
places.
Unstable footing may cause the person to fall and
get injured.
NOTE
• Do not remove the air filter except for during
cleaning. Doing so may damage the unit.
• Do not install anything (such as kitchen paper)
other than the approved air filters on the air inlet.
Doing so may lower operation efficiency and
cause freezing or leakage.
HOW TO CLEAN THE AIR FILTER
