Problem
If the unit is stopped and then immediately started again, the
2-way/3-way will not operate for about 3 minutes, in order to
prevent fuse blowouts.
Whenever the power plug is disconnected and then reconnect-
ed to a power outlet, the protection circuit will operate for about
3 minutes, preventing unit operation during that period.
During operation and immediately after stopping the unit, the
sound of water flowing in the air conditioner's piping may be
heard. Also, noise may be particularly noticeable for about 2 to
3 minutes after starting operation .
During operation, a slight squeaking sound may be heard. This
is the result of minute expansion and contraction of the front
cover due to temperature changes.
Some smell may be emitted from the indoor unit. This smell is
the result of room smells ( furniture, tobacco, ect. ) which have
been taken into the air conditioner.
During Cooling or Drying operation, a thin mist may be seen to
emit from the indoor unit. This results from the sudden
cooling of room air by the air emitted from the air conditioner,
resulting in condensation and misting.
The fan may operate at very low speed during Drying mode or
AUTO operation.
In AUTO operation, the fan will operate at very low speed.
