off automatically
The evaporator coil
has iced up and the
unit does not separate

The LED on the front
panel flashes in red and

Fault
• 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 cab-
inet 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
