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, the 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).
After unit stop, indoor fan will go on running until indoor unit cools down.
