TROUBLESHOOTING
Problem
Possible cause
Solution
The unit does
not work
1. power is abnormal
2. water tank
displaced or full
3.room temperature is too high
or air-outlet is covered
1. contact an electrician to perform
a repair.
2. check water tank placement or empty
water tank.
3. lower room temperature.
Poor
performance
1. Filter is dirty
2. Door & window are open
3. air-inlet or out-let is blocked

surface.
2. Filter is blocked.
1. Place the unit on the flat surface. add
carpet or rubber mat underneath.
2. clean the filter.
The device
does not
dehumidify
The relative humidity in the
room where the dehumidifier is
operating is too low
The dehumidifier dries down to the target
relative humidity set and then goes into
fan only mode until the relative humidity
goes above the set point again
The
dehumidifier
works, but
relative
humidity is
still high
1. The place is too large.
2. There are too many
sources of moisture.
Bathing, washing, drying
clothes and cooking all puts
moisture into the air
3. Paraffin or calor gas heating
can add too much moisture
into air
1. we recommend using a dehumidifier
with a great capacity. Call customer
service line for advice
2. we recommend using a dehumidifier
with greater capacity
3. consider using an alternative heat
sources
The window
s
were clear
and now
condensation
has returned
The outside air temperature
has dropped significantly and
the windows are colder
Set the dehumidifier to 40%RH and run
for longer
I can not
remove the
condensation
from my
window,even
in continuous
or laundry
function
The surface temperature of
the windows is too low for
a dehumidifier to prevent
condensation. Common with
single glazed windows or
poorly insulated houses when
the outside temperature
drops below 0
o
C
Keep running the dehumidifier on
Laundry 24hours a day and if the air
temperature outside increases the
condensation on windows may clear
Dehumidifier
is blowing out
warm air
The dried air is passes over
a heating element before it is
blown into the room as part of
the dehumidification process
This is normal and helpful especially in
the cold weather, a dehumidifier is not
an air cooler.
