1x inlet seal
1x pipe clamp
1. Mark the inlet point on the collection reservoir.
2. Use the supplied hole saw to cut the hole for the inlet into the reservoir wall.
When cutting holes on the collection reservoir, observe the following points:
- Observe the dimensions of the inlet surfaces.
- Max. speed of the drill: 200 rpm.
- Check the hole diameter: DN 100 = 124 mm.
NOTICE! Drill the connection care-
fully. Impermeability of the connection depends on the hole diameter!
- Make sure the excess material in the drill bit is removed completely! If the excess
material removal is reduced, the material will heat up excessively and melt.
⇒ Interrupt the drilling process, allow the material to cool and clean the hole
saw!
⇒ Reduce the speed of the drill.
⇒ Vary the feed pressure when drilling.
3. Deburr and smooth the cut surface.
4. Insert the inlet seal into the hole.
5. Push the pipe clamp onto the inlet seal.
6. Coat the inner surface of the inlet seal with lubricant.
7. Push the inlet pipe into the inlet seal.
Push the inlet pipe 10...20 mm into the collection reservoir.
8. Connect the inlet seal and pipe firmly to the pipe clamp.
Max. tightening torque:
5 Nm.
▶ Inlet connected. Next step: Connect the vent.

Connecting the vent
Connection of a ventilation line is a specified requirement and essential for correct
function of the lifting unit. Observe the following points when connecting the ventila-
tion line:
▪ Guide the ventilation line over the roof.
▪ Ensure all connections are completely tight.
‡
Ventilation line is properly installed.

Installation materials available:
1x pipe clamp
1. Open the connection port: Pull the strip on the Konfix connector and open the
connection port.
2. Put the pipe clamp on the connection port.
3. Attach the ventilation pipe to the connection port.
4. Secure the ventilation pipe on the connection port with the pipe clamp.
Max.
tightening torque: 5 Nm.
▶ Lifting unit is installed. If required, further drainage fixtures or a diaphragm hand
pump can be connected to the additional connection port.
6.4.9
Connecting additional inlets
In general, all drainage fixtures are connected centrally to the lifting unit via an inlet
pipe. However, because this is not always possible, the lifting unit has two additional
connections:

180 mm
1:50

Inlet connection with seal
▪ DN 40 connection on the front longitudinal side
For fixed connection of a diaphragm hand pump.
NOTICE! When drainage fixtures are
connected on the longitudinal side, it is possible that drainage problems will arise
for physical reasons. Install inlet with a pipe loop! The inlet height of the pipe loop
must be 180 mm!
▪ DN 40 connection next to the ventilation connection piece
To connect additional drainage fixtures.
When using additional connections, observe the following points:
▪ Connect the inlet pipe only at the connection port.
▪ Avoid an inlet surge and air intake in the collection reservoir. Route the inlet properly.
CAUTION! Inlet surges or air intake in the collection reservoir can cause malfunc-
tions of the lifting unit!
▪ Ensure all connections are completely tight!
▪ Install gate valve in the inlet!
