During unit operation or at stop, a swishing or
gurgling noise may be heard. This noise is generated
by refrigerant flowing in the system.
Unit will not restart after stop.
During unit operation, a cracking noise may be heard.
This noise is generated by the casing expanding or
shrinking because of temperature changes.
This is because the system circulates smells from the
interior air such as the smell of cigarettes or the
painting on the furniture.
When unit is running at places like restaurant, etc. where
dense edible oil fumes always exist, this will happen.
To prevent frost from accumulating on indoor heat
exchanger, unit will switch to blowing 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.
Please wait 3 minutes
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)
