Adjusting the dryer
Adjusting the air flow may only be carried out by authorized personnel.
The dryer is pre-set for optimal air flow with up to 15 m equivalent pipe length. For longer pipes it is necessary to ad-
just the dryer according to the following instructions.
For default settings from factory, check the label attached on the damper.
Adjust the dryer by demounting the lower back panel and measure the pressure in the fan housing.
Demount the lower back panel.
Demount the heating sensor (NTC sensor) (A) and insert the measuring device. Make sure the connection is tight to
prevent air leakage.
Loosen the screws on the damper and open the damper (B) as much as possible.

Measure with a pressure measuring instrument (manometer) with an empty drum and with a program without heat.
By opening and closing the damper (B) the pressure at the heating sensor (NTC sensor) (A) is either lowered or
raised.
The optimum drying performances are achieved when the measured static pressure correspond to the value listed in
the following table.
