03. Appliance description
The appliance is designed for continuous automatic air dehumidification. It can be trans-
ported and installed easily due to its compact dimensions.
The appliance is equipped with a self-contained, hermetically-sealed cooling unit, a low-
noise and low-maintenance fan, an operating hour meter, a mains switch and a connecting
cable with plug.
The appliance works on the condensation principle (see figure A). The moist room air
is drawn in by the fan and fed through the evaporator and the condenser which lies be-
hind it. Heat is extracted from the air in the cold evaporator. The room air is cooled to
below the dew point and the water vapour in the air condenses as condensate, frost or
ice on the lamellae of the evaporator. The condensate is removed from the appliance
via the water outlet.
The dehumidified, cooled air is warmed up again on the condenser (heat exchanger)
and exhausted into the room by the fan.
The dryer air produced in this way mixes with the room air again. Due to the constant
circulation of the room air through the appliance, the humidity in the room where it is in-
stalled is continually reduced.

04. Installation
For optimum, economic and safe operation of the appliance, it is essential to follow the
instructions below (see also figure B).
• The appliance must be installed in a stable, upright position in order
to ensure that the condensate can drain out without hindrance.
• Install the appliance as far as possible in the centre of the room
to ensure optimum air circulation.
• It is essential to maintain a minimum distance of 50 cm to walls.
• If several machines are installed simultaneously, care must be taken
that the room space is divided evenly between the appliances.
• Make sure that air can be drawn in at the front air inlet and exhausted
at the rear air outlet without hindrance.
• Do not install the appliance near to radiators or other sources of heat.
• Keep the room to be dried or dehumidified closed to the outside air.
• Keep windows and doors closed and avoid entering
and leaving the room frequently.

Important information about the electrical connection
• The appliance must be connected to an electricity supply point with an earth
leakage breaker in accordance with DIN VDE 0100, Part 704.
• If the appliance is installed in wet areas such as laundry rooms, bathrooms
or similar, the appliance must be protected on the site side by an earth leakage
breaker in accordance with regulations.
• Check the specifications on the appliance’s type plate and confirm before
connecting the appliance that the voltage and current rating of the electricity
supply conform to these requirements.
• If a generator is used to supply the power, its rating must be at least 4 KW,
since the required start-up current of the dryer can exceed its nominal rated
current by four to five times.
