When outdoor temperature is low and humidity is high, the
unit sometimes performs defrosting automatically. Please
wait. During defrosting, water or steam may escape from the
outdoor unit.
The indoor fan may stop to prevent re-evaporation of
dehumi ed moisture and to save energy.
This is caused by refrigerating liquid moving within the unit.
This is caused by heat expansion or contraction.
This is caused by the operation of the refrigerant control
valves or electric components.
The noise means that the revolution speed of the compressor
is increasing or decreasing.
This is the sound when operation of another indoor unit is
stopped.
Restart is blocked for 3 minutes after you have stopped the
operation to protect the unit.

very high. It disappears as soon as the temperature and
humidity decrease.

tobacco or cosmetics adhering to the unit.

automatically. Use the remote control to start the operation
again.

section is exposed to direct sunlight or other bright light.
