Unscrew the mounting plate from the enclosure (4 hexagon socket
head screws in the corners) and remove it completely with all mounted
components.
5
Remove the capacitor by undoing the nut at the mounting bracket. Do
not disconnect the wiring!
6
Mark the position of the ribbed plate (pos. 1) and intermediate plate
(pos. 2) by a drawing line with a felt-tip marker (M). This helps to avoid
incorrect assembly later.
7
Undo the 4 screws (pos. 3), remove the washers (pos. 4) and remove
the entire pump head from the pump housing.
8
Turn the fan to bring the membrane (pos. 5) to top dead center. Lift the
edge of the membrane and, gripping it on opposite sides, unscrew it by
turning anti-clockwise.
9
Take the spacer(s) (pos. 6) of the threaded bolt of the membrane and
screw them on the new membrane.
10
Check that all parts are free from dirt and clean them with a cloth or blow
them out with compressed air if necessary.
