Possible Causes
Corrective Action
• When the room temperature decreases,
this phenomenon will disappear
• This symptom requires installing a drain
hose under the base pan. Contact the
installer.
• These are normal symptoms. The noise will
stop.
• If the smell does not disappear, you need
to wash the filter. If this does not work,
contact the service center to clean your
heat exchanger.
• This symptom is normal. Please wait until
the unit has generated enough warm air to
blow through the indoor unit.
• In Heating Mode, ice/frost is built up on the
coils when the outside temperature falls.
This function removes a layer of frost on the
coil, and it should finish in approximately 15
minutes.
• The heating effect may not be sufficient.
