During unit operation, a cracking noise may be heard.This noise is
A cracking noise is heard generated by the casing expanding or shrinking because of
temperature changes.
The is because the system circulates smells from the interior air
Smells are generated
such as the smell of furniture, paint, cigarettes.
During COOL or DRY operation, indoor unit may blow out mist.
Mist or steam are blown out
This is due to the sudden cooling of indoor air.
To avoid frosting on the heat exchanger of the indoor unit, the air
