FREQUENT ENQUIRIES
Q: Why does the dehumidier seem to collect less water in winter?
• In winter, because the temperature is lower than in summer, the eect of the
dehumidier is greatly reduced. Although only a little water collects in the tank,
this is not a malfunction.
Q: Why doesn’t the dehumidier operate? Why does the unit stop operating
suddenly?
• This dehumidier 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 dehumidier may be in“dehumidication mode”, the ambient
temperature is lower or higher (dehumidication cannot be performed when
the ambient temperature is <5°C or >32°C / <41°F or >89.6°F).
The ambient temperature for operation of the dehumidier is 5-32°C or
41°F-89.6°F, and the relative humidity is 30%-80%. The optimal temperature for
use is 16-32°C or 60.8-89.6°F;
Q: Why is hot air blown out from air supply outlet?
• This dehumidier extracts the air in the room, and the dehumidication unit
cools the air, the temperature decreases below the condensation point, the air
condenses into water drops, which falls into water tank nally, and the dehu-
midied air is heated by the temperature returning unit. This can reduce energy
consumption and also accelerate dehumidication, therefore, hot air is blown
out, and this not a fault.

INSTALLATION
• Drain the water tank before use.
• Refrain from opening doors/windows during operation.
• When the dehumidier is installed, a certain space must be reserved around this
dehumidier, the minimum distance above is 50cm, and the minimum distance
in front/rear and left/right is 20cm as required, as shown in gure below.
• Theres loud noise during operation:
Place the unit on top of a mat. This reduces vibration and noise. It also prevents
leaving depressions on carpets.
1. HEPA FILTER INSTALLATION
The HEPA lter screen is installed in the lter frame to purify the air.
• Remove the rear lter frame.
• Install the equipped HEPA lter into the lter frame.
• Install the lter frame back into the machine.

the dehumidier turns o automatically. After the setting is completed, if the Timer
key does not act at all within 5s, the set time is conrmed. In timer o state the key
lamp on the [Timer key] is normally on.
SETTING TIMER ON
When the dehumidier is in standby state, the method for adjustment of setting
time by the [Timer key] is the same as timer OFF. After the setting is completed,
if the Timer key does not act at all within 5s, the set time is conrmed. In timer ON
state the key lamp on the [Timer key] is normally on, and the set time is displayed
on control panel.
AUTO MODE
Select AUTO dehumidication, if the room humidity is high than the set humidity
or is between +5% or -5% of the set humidity, the compressor will starts and the
fan will run at the set speed. If the room humidity is lower than the set humidity by
-5%, then the compressor will stop but the fan will run at the set speed.
The default set humidity value is 50%.
CONTINUOUS MODE
Select CONTINUOUS dehumidication, no matter how the relative humidity in the
room is, the compressor starts, the fan runs at high speed in default, and the air
speed can be regulated via the air speed key.
INSIDE DRYING MODE
Press the [Inside drying key] to start drying in the dehumidier, and the
