 Unscrew screws (pos. 1)
 Remove the pressing plate (pos. 2) and metering head (pos. 3).
 Unscrew the diaphragm (pos. 4) together with the intermediate ring (Item 5) in an
anticlockwise direction.
 If they are stiff, press two metering head screws approximately 15 – 20 mm into the
intermediate ring in order to improve the grip (see Fig. 10.5 "!").
 Remove diaphragm, intermediate ring and protective diaphragm (pos. 6).
 Slide on a new protective diaphragm and press the intermediate ring against it.
 Screw on a new delivery diaphragm in a clockwise direction and hand-tighten it, holding
the intermediate ring in such a way that the delivery diaphragm is pressed against the
intermediate ring with the thumbs.
 Turn the intermediate ring clockwise so that the drain hole points downwards.
 Place on a new metering head and pressing plate and insert metering head screws.
 Tighten metering head screws crosswise.
Tighten each screw in steps of one rotation.
