The sound of water flowing can be heard before, during or
immediately after operation. When it starts working for 2-3 minutes,
the sound may become louder, which is the sound of the refrigerant
flowing or the condensed water draining.
During operations, the air conditioner may make a cracking sound,
which is caused due to temperature changes or the slight dilation of
the heat exchanger.
The terrible smell caused from walls, carpet, furniture, clothing,
cigarette and cosmetics, attaches on the conditioner.
When switching it on again after power failure, turn on the manual
power switch and the operating indicator flashes.

refrigerate while other indoor units are heating. When the operator pre-
sets it to refrigerating or heating mode, but the operation is contrary to
the setting, the awaiting indication is displayed.

units, refrigerant flows in quickly and one can hear the sounds.
Otherwise, when other indoor units perform heating, white steam
