Multi Split System
Problem
Possible Causes
Both the indoor unit and outdoor unit make
noises
A low hissing sound may occur during operation. This is normal
and is caused by refrigerant gas flowing through both the indoor
and outdoor units.
A low hissing sound may be heard when the system starts, has
just stopped running or is defrosting. This noise is normal and is
caused by the refrigerant gas stopping or changing direction.
The outdoor unit makes noises
The unit will make different sounds based on its current
operating mode.
Dust is emitted from either the indoor or
outdoor unit
The unit may accumulate dust during extended periods of
non-use, which will be emitted when the unit is turned on.
This can be mitigated by covering the unit during long periods
of inactivity.
The unit emits a bad odour
The unit may absorb odours from the environment (such as
furniture, cooking,cigarettes, etc.) which will be emitted during
operations.
The unit’s filters have become mouldy and should be cleaned
The fan of the outdoor unit does not operate
During operation, the fan speed is controlled to optimise
product operation.
NOTE: If your problem persists after performing the checks and diagnostics above, turn off your unit immediately and
contact ActronAir on 1800 119 229 for technical support or warranty.
