LAF
Electrical connections
Connect the electric cable to an earthed 230V power outlet. Requisite fuse: See overview of range.To start the LAF 50-150 dehumi-
dier, set the switch to position I (see Fig. C). e electronic control system delays start by about 5 seconds.

e LAF 50E-150E dehumidiers incorporate an electric heater and a two-position switch (see Fig. D).
Position I Dehumidication
Position II Dehumidication + heating
e electric heater will be switched o when the preset room temperature has been reached (set at the factory to 21°C).
e value can be adjusted on the electronic circuit board to between 10°C and 26°C (see the arrow in Fig. E), which should be
carried out by a specialist.
Fig. E
If the ambient temperature is lower than +3°C or higher than +30°C, the dehumidier will be stopped (indicated by the LED). It
will restart automatically when the temperature rises to 5-6°C resp. sinks to 27-28°C. If frost should occur on the evaporator, the
dehumidier will be automatically defrosted once an hour.
