Cause/Remedy
¡ Check to see if the unit is on a slope or uneven surface.
➝ Move to a sturdy even surface.
¡ Check to see if the pre-filter is clogged.
→ Clean according to the maintenance procedures.
¡ Operating the unit in small rooms or in tight spaces sometimes
causes the sound to reverberate.
➝ Place a mat underneath the unit.
¡ The sound increases when the compressor activates (3
minutes after turning on the unit or during One-touch
dehumidifier and Automatic modes).
¡ The volume of the sound differs depending on the angle of the louvre.
¡ This is the sound of the refrigerant.
The sound can be heard while the refrigerant stabilizes after
the unit turns on, changes modes, or stops.
¡ 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.)
¡ The heat converter heats rapidly causing a brief odour. This is
not a malfunction.
¡ 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
¡ Check to see if the power cord is plugged into the power
socket properly.
➝ Plug the power cord into the power socket properly.
¡ Check to see if anything is blocking the air outlet.
➝ Remove the obstruction, and plug the power cord into the
power socket again.
¡ Check to see if the pre-filter is clogged.
➝ Clean according to the maintenance procedures.
¡ Malfunction
➝ Take note of the error message, unplug the power cord, and
seek service assistance using the number on the next page.
