Cleaning
Before carrying out any cleaning, disconnect the power supply to the dehumidifier. Clean the dehumidifier at regular
intervals, as dust and dirt reduce the capacity and may cause overheating and give rise to the risk of fire. Remove the
filter and clean it in running water. Blow the cooling circuit clean using compressed air.
The following cleaning should be carried out by a specialist:
If necessary, release the top cover, and remove it in order to gain access for vacuum cleaning the bottom plate on which
the compressor is mounted. Prior to mounting the top cover, check that the sealing gasket is undamaged, as the water
ingress protection otherwise may be impaired and water come in contact with live parts. Reassemble the top cover.
Pressure limiter
Following shall be carried out by a specialist:
The dehumidifier is equipped with a pressure limiter with manual reset on the high pressure-side of the cooling circuit.
This will stop the compressor if the condensing pressure for some reason would be too high. Release the top cover, remedy
the fault.
Reset the pressure limiter located behind the rubber cap, refer Fig. F and replace the rubber cap. Prior to mounting the
top cover, check that the sealing gasket is undamaged, as the water ingress protection otherwise may be impaired and
water come in contact with live parts. Reassemble the top cover.

Temperature limiter for E models
The following work should be carried out by a specialist:
A dehumidifier with built-in electric heater has two temperature limiters (one of which has manual reset) that are
designed to trip the power supply to the heater in the event of overheating. If the manual temperature limiter has
tripped, disconnect the power supply to the heater and leave the heater to cool. Remove the top cover, correct the fault
and reset the temperature limiter.
Prior to mounting the top cover, check that the sealing gasket is undamaged, as the water ingress protection otherwise
may be impaired and water come in contact with live parts. Reassemble the top cover.
Transport
Before the dehumidifier is transported or moved, any water or ice on the evaporator should run off and the collecting
container should be emptied. Secure the dehumidifier firmly for transport. If transported in the horizontal position,
Position the dehumidifier as shown in Fig. G. The dehumidifier must not be transported in any other position. After
horizontal transport, the dehumidifier should be left upright for at least 30 min before it is started.
