unit may result in fluctuation of the sound. → Clean the air
filters in time.

is normal, if feeling uncomfortable, please deactivate the
"Strong wind" function.
• W hen ambient humidity is high, water drops will be
accumulated around the air outlet or the panel, etc. → This
is a normal physics phenomenon.
• P rolonged cooling run in open space produces water drops.
→ Close the doors and windows.
• T oo small opening angle of the louver blades may also
result in water drops at the air inlet. → Increase the angle of
the louver blades.

happens sometimes. → This is because the indoor air
is cooled rapidly. After it runs for some time, the indoor
temperature and humidity will be reduced and the mist will
disappear.
