During unit start and operation or at stop, a swishing
or gurgling noise may be heard. This noise is generated
by refrigerant flowing in the system.
During unit operation, a cracking noise may be heard.
This noise is generated by the casing expanding or
shrinking because of temperatuer changes.
This is because the system circulates smells from the
interior air such as the smell of cigarettes or the
painting on the unit.
When unit is running at places like restaurant where
dense edible oil fumeis always exist, this will happen.
To prevent frost from accumulating on indoor heat
exchanger, unit will switch to fan operation for a while
then resume cooling operation.
Though ON/OFF button is set
to ON, unit won't resume cooling,
dry or heating operation
in 3 min after it is stopped, this
is because of 3-min-delay
protection circuit.
Unit will reduce fan speed repeatedly and automatically
if room temp. is too low in dry operation.
This occurs when frost accumulated
on the outdoor unit is removed.
(during defrosting operation)
After unit stops, indoor fan will go on running
until indoor unit cools down.
