Installation
The permitted installation positions with vertical motor shaft are shown in Fig. 9.
All installation positions except for "motor facing down" are allowed.
The motor impeller unit can be arranged in four different positions relative to the pump
housing (each offset by 90°).
With twin-head pumps, it is not possible to turn both insertion sets in the direction of
each other to the shaft axes due to the dimensions of the electronic modules.
The motor impeller unit consists of an impeller, lantern and motor with electronic mod-
ule.
Turn of motor impeller unit relative to pump housing
NOTICE
To make the installation work easier, it can be helpful to install the pump in the pip-
ing. Do not connect the pump electrically or fill the pump or system.
1. Leave two transport lugs (Fig. I, Item 30) on the motor flange.
2. Attach motor impeller unit (Fig. 4) to the transport lugs with suitable lifting equip-
ment for protection. To prevent the unit from tipping, place a belt loop around the
motor and adapter of the electronic module as shown in Fig. 6. When attaching,
avoid damaging the electronic module.
3. Loosen and remove the screws (Fig. II, Item 29).
NOTICE
To unscrew the screws (Fig. II, Item 29), use an open-end spanner, angle spanner or
socket wrench with ball head, depending on the type.
We recommend that you use two installation bolts instead of two screws (Fig. II,
Item 29). The installation bolts are screwed diagonally to each other through the
drilled hole in the lantern (Fig. I, Item 36) into the pump housing (Fig. I, Item 24).
The installation bolts make it easier to avoid damaging the impeller when dismant-
ling the motor impeller unit and then reinstalling it.
WARNING

Danger of injury!

Installation bolts alone do not provide sufficient protection against injury.
• Never use without lifting equipment!
4. Loosen the screw (Fig. I and Fig. III, Item 10) to remove the holder for the differen-
tial pressure sensor (Fig. I, Item 13) from the motor flange. Suspend the differential
pressure sensor (Fig. I, Item 8) with the holder (Fig. I, Item 13) from the pressure
