Installation and operating instructions • Wilo-Stratos GIGA2.0-I, Wilo-Stratos GIGA2.0-D • Ed.02/2022-07
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 module.
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 piping. 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 equipment
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 dam-
aging the electronic module.
3. Loosen and remove the screws (Fig. I/II/III, Item 29).
NOTICE
To unscrew the screws (Fig. I/II/III, 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 mounting bolts instead of two screws
(Fig. I/II/III, 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
dismantling the motor impeller unit and then reinstalling it.
WARNING

Danger of injury!

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