This dehumidifier may be full of water or water tank is not installed
properly, drain the water in water tank, or re-install water tank in
correct way.
At the moment the dehumidifier may be in the “dehumidification mode”,
the ambient temperature is lower or higher (dehumidification cannot be
performed when the ambient temperature is ＜5℃or ＞32℃).
The ambient temperature for operation of the dehumidifier is 5-
32 ℃
, and the relative humidity is 30%-80%. The optimal temperature
for use is 16-32℃;
Why has the dehumidifier stopped working/
won’t work?
Q:
Frequent enquiries
Q: Why is hot air blown out from air supply
outlet?
⚫ This dehumidifier extracts the air in the room, and the
dehumidification unit cools the air, the temperature decreases below
the condensation point, theair condenses into water drops, which
falls into water tank finally, and the dehumidified air is heated by the
temperature returning unit. This canreduce energy consumption and
also accelerate dehumidification, therefore, hot air is blown out, and
this not a fault.

◆ Please drain the water fromwater tank before operating.
◆ During operation please keep windows and doors short when
possible as the unit works best in sealed conditions.
◆ When the dehumidifier is installed, a certain space must be
reserved around this dehumidifier, the minimum distance
above is 50cm, and the minimum distance in front/rear and
left/right is 20cm as required, as shown in figurebelow.
◆ If a vibration sound is present during operation of this
dehumidifier:
It is recommended inserting pads or damping rubber sheets,
etc. below this dehumidifier, this can reduce vibration and
noise, and can also reduce sinking of wood floor or carpet.
