Installing the
mounting plate
with pump
11
Turn the fan until the connecting rod is at top dead center. Then screw
the new membrane with the spacer(s) on the connecting rod (clockwise)
and tighten it by hand.
12
Separate the ribbed plate and intermediate plate. To do so, remove the
screw caps (pos. 7) using a small screw driver, undo the screws (pos.
8), and remove the disk springs (pos. 9) and washers (pos. 10).
13
Remove the valve plates (pos. 11) from the intermediate plate.
14
Check that the valve seats, intermediate plate and ribbed plate are free
from dirt. Replace them if they are deformed, scratched or corroded.
Contact WTW in this case.
15
Insert the new valve plates in the valve seats of the intermediate plate.
The valve plates for the pressure and intake side are identical. Check
that the valve plates are not deformed by moving them gently sideways
in their seats.
16
Place the ribbed plate on the intermediate plate in the position indicated
by the felt-tip line marking (M). Check that the ribbed plate is centered
by moving it gently sideways.
17
Screw together the ribbed plate and intermediate plate. For correct ori-
entation of disk springs (pos. 9) see detail drawing. Torque: 2.5 Nm.
Then install the screw caps (pos. 7) on the screw heads.
18
Turn the fan until the membrane is at top dead center.
19
Place the pump head on the housing with the correct orientation. Then
tighten the screws (pos. 3) with the washers (pos. 4) gently, evenly and
diagonally.
20
Turn the fan to check that the pump rotates freely. Turn the fan again to
bring the membrane to top dead center and tighten the screws by hand
diagonally (torque 3.5 Nm).
21
Screw the capacitor on the mounting bracket. Make sure the nut sits
tightly and the cable routing is correct.
22
Insert the mounting plate with the mounted components in the housing
and fix it at the corners with the four hexagon socket head screws.
23
Connect the two blue hoses to the pump head (pressure side at the
front!).
24
Connect the power cable and control line to the terminal strip. While
doing so, pay attention to the specifications on the label located on the
right side of the terminal strip.
25
Close the enclosure of the Cleaning Air Box.
