4.4 Ventilation pipe
For exposed installation, make sure that the preassembled vent valve incl. activated carbon filter (1) is screwed on tightly.
For use in the chamber, dismantle the vent valve and route the ventilation hose above the backwater level.
Connecting the ventilation pipe
To ensure the function in all use cases in the chamber in the
event of flooding, the ventilation pipe must be routed at least
15 cm above the backwater level.
The ventilation pipe must be laid so that it does not hinder
access for maintenance purposes or the other pipe connec-
tions (pressure pipe/cable conduit).
Unscrew the vent valve (1) from the pump unit (2).
Fix the ventilation pipe onto the connection (3) of the vent
valve (1/2 inch thread)
Make sure the seal between the ventilation pipe and the
drain body fits properly.
4.5 Setting up the pressure pipe connection
Remove the sealing plug (2) from the drain body (3).
Insert the seal (1).
Mount the connector (4) from inside the drain body to the
intermediate section (3) and tighten the nut (5) from the
outside to approx. 10 Nm.
Connect the on-site pressure pipe to the connector.
