1. Loosen the diaphragm (15) by turning to
the left - use pliers if necessary.
2. If the threaded rod (16) has come loose
together with the diaphragm, unscrew
the diaphragm from the threaded rod
(turning to the left) - using pliers if nec‐
essary.
3. Screw the threaded rod into the con‐
necting rod thread and use a flat wrench
(SW9) to tighten securely at the width
across flats.
4. Position the backplate (14) on the pump
housing.
5. Screw the diaphragm onto the threaded
rod and tighten manually. Ensure that
the backplate no longer moves from
side to side, although it should still be
able to turn slightly.
6. Place the dosing head (2) with the
screws (1) onto the diaphragm (3) and
the backplate (4) - ensure that the suc‐
tion connector points downwards in the
pump's subsequent fitting position.
7. Gently tighten the screws (6a) and then
tighten cross-wise.
