Possible Causes
TROUBLESHOOTING
Corrective Action
• Allow the Auto Clean function to continue since
it removes any remaining moisture inside the
indoor unit. If you do not want this feature, you
can turn the unit off.
• 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.
