Installation and operating instructions Wilo-Yonos GIGA2.0-I/-D
Installation
The permitted installation positions with vertical motor shaft are shown in Fig. 10.
All installation positions except for "motor facing down" are allowed.
The motor impeller unit can – relative to the pump housing – be arranged in various
positions.
ƒ
DN 32 ... DN 80: eight different positions (8x45°)
ƒ
DN 100 ... DN 125: four different positions (4x45°)
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. I/II, Item 29).
NOTICE
To unscrew the screws (Fig. I/II, Item 29), use an open-end wrench, Allen key or
socket wrench with ball head, depending on the type.
4. Loosen the screw (Fig. I, Item 29, Fig. II, Item 10) to remove the holder for the dif-
ferential pressure sensor (Fig. I, Item 13) from the motor flange. Suspend the dif-
ferential pressure sensor (Fig. I, Item 8) with the holder (Fig. I, Item 13) from the
pressure sensing lines (Fig. I, Item 7). Disconnect the connection cable of the dif-
ferential pressure sensor in the electronic module, if necessary.
CAUTION
Material damage due to bent or kinked pressure sensing lines.
Improper handling can damage the pressure sensing line.
When turning the motor impeller unit, do not bend or kink pressure sensing lines.
