This is caused by heat expansion or
contraction of plastics
Air blown out from the indoor unit
sometimes smells. The smell results from
smells of furniture, paint , tobacco
absorbed by indoor unit.
During operation, white fog comes out of
indoor unit.
When in COOL or DRY mode, a thin water
fog can be seen blown out of unit ,this is
the condensed fog because the suddenly
cooled indoor air is blown out.
