Before asking for servicing or repairs, check the following points.
The FILTER indicator turns on.
• This indicator turns on after PURE operation has been performed for approximately 1000 hours.
• The indicator may turn on if the front panel is not firmly closed.
• The indicator may turn on if the plasma pure filter is not securely attached.
Sounds made from the indoor unit
• The plasma pure filter may make a humming, clicking, or buzzing sound when it is dirty.
• When the power is turned on or the air conditioner is stopped, the vertical air louvers may make a rattling sound or shuttling
sound.
• Some parts may expand or shrink due to temperature fluctuations, and this can result in a slapping sound.
• When the refrigerant is flowing, a hissing sound or gurgling sound can result.
• A hissing sound can be made when the air conditioner is switched to defrosting operation during heating operation.
Sounds made from the outdoor unit (heat pump models)
• A rustling sound can be made when the air conditioner is switched to defrosting operation during heating operation.
COOL, DRY, or HEAT operation cannot be performed. (For multi outdoor unit connection)
• When the unit in other room operates previously in different mode, FAN ONLY operation is performed because of first-push
priority control. (COOL operation and DRY operation can be concurrently performed.)
