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.

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.

the result of room smells ( furniture, tobacco, ect. ) which have
been taken into the air conditioner.

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.

AUTO operation.
