1. Mark the inlet point on the pump chamber.
2. Use the supplied hole saw to cut the hole for the inlet into the pump chamber wall.
When drilling holes on the pump chamber, observe the following points:
- Observe the dimensions of the inlet surfaces. CAUTION! The drilled hole must
be completely within the marked inlet surfaces!
- Max. speed of the drill: 200 rpm.
- Check the hole diameter: DN 100 = 124 mm (5 in). NOTICE! Drill the connection
carefully. Impermeability of the connection depends on the drilled hole!
- Make sure the excess material in the drill bit is removed completely! If the excess
material removal rate decreases, the material will heat up too quickly and melt.
⇒ Stop the drilling process, allow the material to cool down 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 50 mm (2 in) into the pump chamber.
8. Connect the inlet seal and pipe firmly to the pipe clamp. Tightening torque: 5 Nm
(3.7 ft·lb).
▶ Inlet connected. Next step: Connect the aeration and venting.
The connection of an aeration and venting line is a specified requirement. Observe the
following points when connecting the aeration and venting line:
ƒ
For building installation: Guide the aeration and venting line over the roof.
ƒ
All connections must be completely tight.
