Solution
Wait until the voltage re-
sumes normal.
Clean the fi lter.
Adjust temperature
proper range.
Close door and window.
Disconnect power,
back power, and then turn
on the unit again.
The noise is the sound of
refrigerant fl owing inside
the unit, which is a normal
phenomenon.
This is the sound of fric-
tion caused by expansion
and or contraction of panel
or other parts due to the
change of temperature.
Disconnect the power for
3s and then connect the
power; if the problem still
exits, disconnect the pow-
er, reinstall the air guide
louver (install the upper
air guide louver and then
install the lower air guide
louver) and then connect
the power.
