If the dehumidifier is not functioning correctly, shut it down immediately
Use this table to localize and solve a possible problem or fault:
Fault
The dehumidifier does
not start when power
is connected
The unit was switched
off automatically
The evaporator coil
has iced up and the
unit does not separate
water
The LED on the front
panel lights up in red
and the water tank is
empty
The water tank is full
and yet the dehumidi-
fier is not switched off
If you cannot find the reason for the fault, switch off the unit immediately in order to pre-
vent further damage. Contact a service technician or a Dantherm Air Handling repre-
sentative.
• Check external fuses
• Check that the power supply to the units is correct
• Check that the switch on the side is ON
• Check the built-in hygrostat by setting it on a lower rela-
tive humidity. This is done by turning the hygrostat knob
clockwise. If the unit does not start, check the built-in
hygrostat for faults
If it starts after 44 minutes, but switches off again shortly af-
terwards, check the following:
• Check that the fan is running when the unit starts after
44 minutes
• Check whether the condenser coil is dirty
• Check whether the filter is dirty
• Check whether the room temperature is above 30 °C. If
the unit has not been switched off automatically at a
room temperature above 30 °C, it should be switched
off.
• Check that the air inlet on the front and the air outlet
through the grill on the sides are not blocked.
• Check whether the room temperature is below 3 °C. If
so, and the unit has not automatically been switched off,
it should be switched off.
• Check that the air inlet on the front and the air outlet
through the grill on the sides are not blocked
• Check that the float is lying loose in the water tank and
that it can move freely up and down. Check that the float
is not damaged
• Check that the water tank is placed in the water tank
cabinet and that the float is turned towards the magnetic
switch
• Check that the float is lying loose in the water tank and
that it can move freely up and down. Check that the float
is not damaged
