Symptom: Air Blow Direction Is Not As Specified; Symptom: White Mist Comes Out Of A Unit (Indoor Unit); Symptom: Noise Of Air Conditioners (Indoor Unit); Symptom: Dust Comes Out Of The Unit - Daikin FBA35A2VEB Operation Manual

▪ The air conditioner does not restart immediately when the
temperature setting button is returned to its former position after
pushing. It does not restart immediately because one of its safety
devices actuates to prevent the air conditioner from being
overloaded. The air conditioner will turn on again automatically
after 3 minutes.
▪ The outdoor unit has stopped. This is because the room
temperature has reached the set temperature. The unit switches
to fan operation. " " (external control icon) is displayed on
the user interface and the actual operation is different from the
user interface setting. For multi-split models, the microcomputer
executes the following control depending on the operation mode
of other indoor units.
▪ The fan speed is different from the setting. Pressing the fan speed
control button does not change the fan speed. When the room
temperature reaches the set temperature in heating mode or the
unit's maximum capacity is reached, the outdoor unit will stop
operation and the indoor unit will operate in fan only mode (low
fan speed). In case of multi-split, the indoor unit alternately
operates in fan stop mode and fan only mode (LL= low fan
speed). This is to prevent the cool air from being blown directly
onto anyone present in the room.
6.1.2 Symptom: Air blow direction is not as
specified
Actual air blow direction is not as shown on the user interface.
Automatic swing setting does not work.
Refer to the manual of the user interface.
6.1.3 Symptom: White mist comes out of a unit
(Indoor unit)
▪ When humidity is high during cooling operation (in oily and dusty
places). If the interior of an indoor unit is extremely contaminated,
the temperature distribution inside a room becomes uneven. It is
necessary to clean the interior of the indoor unit. Ask your dealer
for details on cleaning the unit. This operation requires a qualified
service person.
▪ When the air conditioner is changed over to heating operation
after defrost operation. Moisture generated by defrost becomes
steam and exits.
6.1.4 Symptom: Noise of air conditioners
(indoor unit)
▪ A "ringing" sound is heard after the unit is started. This sound is
generated by the temperature regulator working. It will quiet down
after about a minute.
▪ A continuous low "hissing" sound is heard when the system is in
cooling or defrost operation. This is the sound of refrigerant gas
flowing through both indoor and outdoor units.
▪ A hissing sound which is heard at the start or immediately after
stopping operation or defrost operation. This is the noise of
refrigerant caused by flow stop or flow change.
▪ A "squeaking" sound is heard when the system is in operation or
after the stop of operation. Expansion and contraction of plastic
parts caused by temperature change makes this noise.
