5. Turn the drive to the desired position.
6. Screw in the screws (Item 10) again.
7. Reassemble the holder of the differential pressure sensor. Tighten the screws (Item 10)
firmly. Observe torques. Reconnect the connection cable of the differential pressure
sensor in the electronic module, if necessary.
8. Attach the differential pressure sensor to one of the screws on the holder (Item 13).
Slide the holder under the head of one of the screws (Item 29). Finally, tighten the
screw (Item 29).
9. Reconnect the connection cable of the differential pressure sensor.
If the electronic module has been disconnected, reconnect all cables.
⇒ Further steps for pumps according to Fig. II and Fig. III:
10. Loosen and remove the screws (Fig. II, Item 29 and Fig. III, Item 10).
11. Loosen the screw (Fig. II, Item 29 and Fig. III, Item 10) to remove the holder for the dif-
ferential pressure sensor (Fig. I, Item 13) from the motor flange.
Suspend the differential pressure sensor (Fig. I, Item 8) with holder (Fig. I, Item 13) from
the pressure measuring lines (Fig. I, Item 7).
Disconnect the connection cable of the differential pressure sensor in the electronic
module, if necessary.
12. Remove the motor impeller unit (Fig. 4) from the pump housing. Use the two threaded
holes M10 (see Fig. 99) and use suitable screws provided on-site (e.g. M10 x 20 mm).
The slots (see Fig. 99, Item 2) can also be used for pressing off.
13. Loosen the connected cable of the differential pressure sensor.
If the electronic module is electrically connected, loosen all connected cables or detach
the electronic module from the adapter plate and secure it.
14. Securely place the motor impeller unit on a suitable workstation.
15. Fig. II: Loosen screws Item 10b.
Fig. III: Loosen screws Item 10a.
16. Turn the lantern to the desired position.
NOTICE
The screws Fig. II, Item 10b and Fig. III, Item 10a are factory-fitted auxili-
ary screws that are no longer needed. They can be fitted again or dis-
pensed with.
17. Attach motor impeller unit (Fig. 4) to the transport lugs with suitable lifting equipment
for protection.
To prevent the unit from tipping, place a belt loop around the motor (Fig. 6). When at-
taching, avoid damaging the electronic module.
18. Insert the motor impeller unit into the pump housing with the air vent valve facing up-
wards. Observe the permitted installation positions of the components when doing
this.
The use of installation bolts is recommended (see section "Accessories" [} 135]).
If the motor impeller unit has been secured with at least one screw (Item 29), the fixa-
tion material can be removed from the transport lugs.
19. Screw in the screws (Item 29) but do not tighten them all the way.
20. Secure the differential pressure sensor to one of the screws on the holder (Fig. I,
Item 13). Slide the holder under the head of one of the screws (Fig. I, Item 29). Finally,
tighten the screw (Fig. I, Item 29).
21. Reconnect the cable of the differential pressure sensor.
If the electronic module has been disconnected, reconnect all cables.
If the electronic module has been removed from the adapter plate, re-mount the elec-
tronic module.
