Installation and operating instructions • Wilo-Stratos GIGA2.0-I, Wilo-Stratos GIGA2.0-D • Ed.02/2022-07
NOTICE
If the differential pressure sensor is turned, do not interchange the dis-
charge and suction sides on the differential pressure sensor!
For additional information about the differential pressure sensor, see
"Electrical connection" [} 150] section.
DANGER
Risk of fatal electrical shock!
Immediate risk of fatal injury if live components are touched.
• Before commencing work, switch off the power supply and secure it
from being switched on again.
The drive consists of a motor and an electronic module.
Turn of the drive relative to pump housing
The lantern position is maintained, the air vent valve points upwards.
NOTICE
For the following steps, observe the screw tightening torque specified
for the respective thread type! See "Screws and tightening torques
[} 145]" table.
✓ Steps 1. and 2. are the same for all pumps according to Fig. I ... Fig. III.
1. Leave two transport lugs (Fig. I, Item 30) on the motor flange.
2. Attach drive 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).
Avoid damage to the electronic module during attachment.
NOTICE
To unscrew the screws (Fig. I and Fig. III, Item 10), 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. I and Fig. III, Item 10). The installation bolts are screwed diagonally
to each other through 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!
⇒ Further steps for pumps according to Fig. I
3. Loosen and remove the screws (Fig. I, Item 10).
4. Loosen the screw (Item 10) to remove the holder for the differential pressure sensor
(Item 13) from the motor flange.
Suspend the differential pressure sensor (Item 8) with holder (Item 13) from the pres-
sure measuring lines (Item 7).
Disconnect the connection cable of the differential pressure sensor in the electronic
module, if necessary.
