The temperature in the room may be set by means
of the control knob (Fig. 8). Once the pre-set tem-
perature is produced, the thermostat will automati-

beyond the pre-set value, the system will switch the
heating elements on again.

of time, clean it before shoving by blowing the inside

dry and clean place. Before you start using it again
make sure the power supply cable has not been da-
maged. In the case of any doubts contact the seller
or approved service centre.
