Maintenance (For Service Personnel) - Daikin FHQ35CBVEB Operation Manual

• 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 oper-
ation. (*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 "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 OPERA-
TION.
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.
