z If the symptoms persist even after following the prescribed remedies, or the error message does not
disappear, unplug the power cord, and seek service assistance using the number on the next page.
z If the supply cord is damaged, it must be replaced by the manufacturer, its service agent or similarly
qualified persons in order to avoid a hazard.
Cause/Remedy
z Check to see if the unit is on a slope or uneven surface.
→ Move to a sturdy even surface.
z Check to see if the pre-filter is clogged.
→ Clean according to the maintenance procedures.
z Operating the unit in small rooms or in tight spaces sometimes
causes the sound to reverberate.
→ Place a mat underneath the unit.
z The sound increases when the compressor activates (3 minutes
after turning on the unit or during One-touch dehumidifier and
Automatic modes).
z The volume of the sound differs depending on the angle of the
louvre.
z This is the sound of the refrigerant.
The sound can be heard while the refrigerant stabilises after the
unit turns on, changes modes, or stops.
z This is the sound of the compressor.
In modes that monitor the humidity level or during drying inside,
the compressor operates intermittently causing the sound to be
heard occasionally.
The compressor does not activate after turning the unit off, or for
3 minutes after plugging the unit into a power socket. (This is to
protect the compressor from damage.)
z The heat converter heats rapidly causing a brief odour. This is not
a malfunction.
z The moisture expelled from inside the unit may smell due
to odorants that were not caught by the photocatalytic filter
dissolving in the water. This is not a malfunction.
Cause/Remedy
z Check to see if the power cord is plugged into the power socket
properly.
→ Plug the power cord into the power socket properly.
z Check to see if anything is blocking the air outlet.
→ Remove the obstruction, and plug the power cord into the
power socket again.
z Check to see if the pre-filter is clogged.
→ Clean according to the maintenance procedures.
z Malfunction
→ Take note of the error message, unplug the power cord, and
seek service assistance using the number on the next page.
