Troubleshooting
• The unit does not operate if it is turned on
immediately after it is turned off. This is to protect
the unit. You should wait about 3 minutes to
restart.
• Be sure the unit is in the correct mode and within
it's designed operation limits. If temperatures
outside are too low the unit may not operate.
• Some odors may be emitted from the indoor
unit. This maybe the result of room smells (such
as furniture, tobacco, etc.) which have been
taken into the air conditioner's intake and are
being exhausted back out.
• Consult authorized service center for cleaning if
the odors still exist after any sources of odor in
your home have been removed.
• A swishing noise, like water flowing is the
refrigerant flowing inside the unit. This is a
normal noise during operation.
• During cooling operation, a thin mist may
be seen emitted from the indoor unit due to
high room temperature and humidity. The
mist will disappear, as the room temperature
and humidity decreases. This is normal
under high room temperature and humidity
conditions.
• This is the sound caused by expansion and/
or contraction of panel or other parts due to
the change of temperature. This is normal.
