10 Filling and Venting the System

The system must be thoroughly flushed before
Note
the pump is started up to prevent contami-
nants or foreign bodies from remaining in the
system.
Fill and vent the system correctly. To vent the
pump, loosen the indicated screw by turning it
anti-clockwise. Caution! Hot water may escape
here, depending on the system's operating state.
Then tighten the union nut with 30 Nm torque.
Afterwards, you can start the pump in the desired mode.
Incomplete venting can lead to noises in the pump and sys-
tem.
Warning! Risk of burns!
The entire pump can be very hot,
depending on the operating state of the system.
Tighten the union nut with 30 Nm torque.
Use filter wrench.
