Mounting the supply pressure regulator
3.2.1 Turning the supply pres-
sure regulator
The supply pressure regulator can be turned
on its connecting plate to allow the set point
screw to face either up or down.
1. Unscrew the two fastening screws and lift
the supply pressure regulator off its con-
necting plate.
2. Pull the diverting gasket out of the regu-
lator and keep it in this position.
3. Turn the regulator 180 degrees and rein-
sert the gasket. In this way, you keep the
bore assignment of the gasket for supply
air input and regulator outlet.
Î The long rubber nger of the gasket must
always point in the direction of the regu-
lator outlet (reduced supply pressure).
4. Fasten the supply pressure regulator onto
the connecting plate.
