Alternative measuring method
Adjusting the air flow may only be carried out by authorized personnel.
Use a home made U tube manometer, a hose (max. outer ⌀ 10 mm and min. outer ⌀ 5 mm), with water. Insert one
end of the hose in the hole (A) (after the NTC-sensor has been removed), hold the hose according to the picture so
that the water is in level.
Start the machine and measure the difference between the water in one of the hose ends with the other.
1 mm = 10 Pa.

sition with the wing nut.
Remount the front panel and insert the filter drawer.
