FTXM20~4 FTXM20~71R2V1B
Daikin room air conditioner
4P518786-5F – 2020.06

9.1.6 Symptom: A clapping sound is heard

This  sound  is  generated  when  an  external  device  sucks  air  out  of  the  room  (e.g.
exhaust fan, extractor hood) while the doors and windows in the room are closed.
Open the doors or windows, or turn off the device.

9.1.7 Symptom: White mist comes out of a unit (Indoor unit, outdoor unit)

When  the  system  is  changed  over  to  heating  operation  after  defrost  operation.
Moisture generated by defrost becomes steam and is exhausted.

9.1.8 Symptom: The units can give off odours

The unit can absorb the smell of rooms, furniture, cigarettes, etc., and then emit it
again.

9.1.9 Symptom: The outdoor fan rotates while the air conditioner is not in operation

After  operation  has  stopped.

  The  outdoor  fan  continues  to  rotate  for  another

30 seconds for system protection.

While the air conditioner is not in operation.

 When the outdoor temperature is

very high, the outdoor fan starts to rotate for system protection.

9.1.10 Symptom: Indoor unit fan speed does not correspond with the setpoint (during low

ambient cooling operation in Multi system)

During  low  ambient  cooling  operation  in  Multi  system,  indoor  unit  may  change
fan speed to high regardless of the user setting to defrost the indoor unit heat
exchanger.

9.2 Solving problems based on error codes

Fault diagnosis by user interface

If  the  unit  runs  into  a  problem,  you  can  identify  the  fault  by  checking  the  error
code  by  the  user  interface.  It  is  important  to  understand  the  problem  and  take
measures  before  resetting  the  error  code.  This  should  be  done  by  a  licensed
installer or your local dealer.
