Optimum Operation; Maintenance (For Service Personnel) - Daikin FBQ60EVE4 Operation Manual

• If the PROGRAM DRY OPERATION is used
when the indoor temperature is low, frost forms
the heat exchanger of the indoor unit. In this case,
the air conditioner automatically switches to the
DEFROST OPERATION for a while.
The low fan speed or a gentle wind is used to
prevent the discharge of melt water.

• Sound pressure level is less than 70 dB(A).

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.
• Set the airflow flap of the air discharge grille
horizontally not to obstruct the wind.
Otherwise, the wind will not come out and a
failure may result.
• 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 this page.)
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 8. MAINTENANCE on this page.) (*2)
*1 The consumed power while the outdoor unit is
