Before mounting the new diaphragm, clean the insert as well

section (3) and wipe off any oil.
Mounting is carried out in the reverse order.

30Nm, then crosswise with 70Nm.
2. Before starting up leave the pressure control valve in the
open position for about 2 minutes while the motor is run-
ning (bleeds the unit). Only then close it until the noise of
the inlet valve can be heard.
