CONDITION
CAUSES OR CHECK POINTS
After an operation stop, the air
conditioner does not perform a
restart immediately.
• This is normal. A protective function (3 minutes delay) is active
to avoid damages to the compressor each time the air conditioner
must be restarted after a stop condition.
Various noises are emitted from the
Indoor Unit.
• When Cooling is started or Heating is stopped, a swishing or a
gurgling noise may be heard. This noise is generated while the
refrigerant is flowing in the air conditioner.
• When starting or stopping operation, a cracking noise may be
heard. This noise is generated by the Indoor Unit’s parts because
of temperature changes.
• A whooshing noise may be heard when operating mode
is changed (from Cooling to Heating or vice versa) and the
air conditioner is running. This noise is generated when the
refrigerant changes direction inside the refrigerant circuit.
Air does not flow out of the Indoor
Unit or airflow speed cannot be
changed.
• During operation in Dry mode, the fan speed is always set to
“LO”, to prevent excessive cooling.
• During start-up in Heating mode, air does not flow out until the
indoor heat exchanger is warm enough to prevent emission of
cold air drafts into the room.
• During the thawing (de-icing of the outdoor unit heat exchanger),
air may not flow.
Cooling/Heating effect is not
sufficient to satisfy the user’s
comfort needs.
• The air conditioner could not work efficiently if the air filters are
clogged or dirty.
• Make sure the room temperature has not yet reached the desired
level: compare the room temperature with the set temperature.
• Make sure the airflow speed is not set to “LO”.
• Make sure the air inlet or outlet on both Indoor and Outdoor
Units are not blocked by any obstacles.
• If the rating power of the air conditioner is not adequate because
the room is too wide or the outdoor temperature is too low, add
other appliances.
The transmission indicator on the
remote controller does not light up
at all or dims when sending signals
to Indoor Unit.
• Make sure the dry batteries (2 batteries, “AAA” type) have
enough charge. Replace both batteries with new ones if
necessary.
• Make sure the batteries are inserted in the right direction with
regard to polarity indicated on the remote controller itself.
Misting on the surface of the Indoor
Unit.
• During operation in Cooling mode. This indicates that the room
temperature is already at a very low value.
Steaming from the Outdoor Unit.
• During operation in Heating mode. This indicates that de-icing
is being performed on the outdoor unit heat exchanger.
Unit does not start.
• Check if electric power is available and whether the Unit is
correctly connected to the power source.
• Check whether the batteries in the remote controller are
charged.
• If Timer has been set, check if settings are correct.
