The following symptoms are not faults. Please continue to use it without fear.
Troubleshooting
Is it faulty?
Hot air and water coming
out from the outdoor unit
during heating operations.
● When the outdoor temperature is low and humidity is high, frost will collect
at the outdoor unit. The defrosting causes them to turn into hot air and
water.
No, it is okay
The room has a peculiar
odour.
● The “environmental odours” derived from walls, carpets, furniture, clothes and etc.,
are being circulated in the ventilation system.
ODOUR WASH LAMP BLINKING
● The accumulated odour from the interior of the air conditioner had permeated the
air. Open all windows while operating the unit and the ventilation system.
ODOUR WASH lamp
blinking
● Odour removing operation in progress for 20 minutes, the lamp blinks. (Page 16)
● Timer setting of odour clear operation in progress for 50 minutes, the lamp blinks.
(Page 17)
Indoor unit operation
lamp blinking.
● Starting of automatic operations
The lamp will be blinking when certain types of operating modes are being selected.
On confirmation of certain type of operating mode, the lamp will be on.
● Starting of heating operations
The lamp will be blinking when air outflow has been stopped to prevent cold air from
coming out.
● During heating operations
When the outdoor temperature is low and humidity is high, frost will collect at the
outdoor unit. During defrosting (Defrosting operations), the lamp will be blinking.
Please wait for 12 minutes for the operation to complete.
Air outflow do not come
out.
Air outflow stopped.
COOLING • DRY (During automatic fan speed mode with the ODOUR WASH lamp on)
● Starting of heating operations..... No air outflow for approximately 40 seconds (Page 16)
To prevent the outflow of air that carries those
environmental odours.
● Operations in progress………..…There are times when there is air outflow and
stopping of air outflow due to energy saving mode
activated when the room temperature reaches the
set temperature.
DRY (fan speed setting)
● To prevent extreme cooling, there are times when the air outflow is stopped.
The air outflow will resume after the room temperature has increased.
HEATING
● Starting of heating operations…..There may be no air outflow yet to prevent cold air
from being blown out.
● During defrosting operations…....There may be no air outflow to allow the outdoor
unit to defrost.
Immediately no outflow of
cold air or warm air.
● On resumption of operations after stopping, the air outflow will be on hold for 3
minutes, to protect the air conditioner.
There is noise.
● Occasionally there is a knocking sound.
This is the sound caused by the switching over of refrigerant gas in the system
during defrosting and end of operations.
● “Pitt” sound:
Caused by shrinkage of the resin made parts of the air conditioner due to change in
temperature.
● Sound of flowing water:
Caused by the flow of refrigerant gas through the air conditioner system.
Presence of condensate
during cooling operations.
● Caused by the condensation of the water vapour found in the room air, upon contact
with the cold air outflow from the air conditioner.
Air outflow continues
even after operation has
stopped.
● Extraction of remaining heat in the indoor unit. (Maximum duration: 30 seconds)
Vertical louvres closed
during operations
● During heating
The vertical airflow direction louvres are closed to prevent the outflow of cold air.
