Cause / Solution
This is for protection of the system. After a stop, the sys-tem does
not start operation for approx. 3 min
This is because the system circulates smells from the interior air
such as the smell of cigarettes, cosmetics, the walls or furniture.
When cooling is started or heating is stopped, a swishing or a
gurling 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 casing expanding or
shrinking because of temperature changes.
A whooshing noise may be heard during operation of the system.
This noise is generated when the refrigerant changes direction.
During the dry mode operation, air may not flow out, to prevent
excessive cooling.
During the heating operation, air does not flow out until the air
is heated enough to prevent cold air flow. During the thawing in
heating, air may not flow.
The cooling/heating function may not work effectively when the
air filter is clogged with dust and dirt.
Make sure the room temperature has not yet reached the
designated level.
Make sure the air flow speed is not set at "LO".
Make sure the inlet or outlet of the outdoor unit is not blocked.
When the room temperature has not reached the required level
because of low ambient temperature, add other heating
facilities.
Make sure if the dry batteries have enough charge. Use dry R-03
(AAA) batteries. Replace worn dry batteries with a new pair
batteries.
Make sure the dry batteries are set in the right polarity
directions.
It is caused by chilled air in cooling operation.
It is caused by defrosting of outdoor unit in heating operation.
