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 air 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 Easy 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, 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 an odour. This is not
a malfunction.
¡ 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 air filter is clogged.
➝ Clean according to the maintenance procedures.
¡ Malfunction
➝ Unplug the power cord, take note of the error message,
and contact the place of purchase.
