4.2 Chamber installation
Insert the chamber and align it horizontally.
If necessary, fix the chamber in place vertically using lean concrete.
When installed in groundwater, secure the chamber against buoyancy.
Backfill the remaining space (see "Fig. 1: Soil excavation", page 29) in sections using 0/16 fill material. After every 30 cm
compact to DPr = 97%, up to the height of the ground edge or standard road structure.
4.3 Pipe connection
Connect inlet pipe (note gradient, use socket if necessary)
Insert cable duct.
Insert ventilation pipe (route pipe to above the roof).
4.4 Fit on the vertically adjustable upper section
Fit vertically adjustable upper section provisionally.
Adjust the upper section according to the ground level (if
it rests on the cable duct, shorten accordingly, e.g.with jig
saw).
Position the cover plate with suitable load class.
Fix polymer cover plates to ensure child/third party safety.
4.5 Connect pump and riser pipe
Push the seal onto the pressure pipe connection.
Fit the riser pipe onto the pressure pipe connection of the
pump.
Lower the pump incl. riser pipe into the chamber using
the handle.
Close the one-handed closure.
If necessary, adjust the height of the riser pipe:
Loosen the hose clamp.
Align the backflow preventer (horizontal pipe) vertically.
(Faulty installation impairs the performance of the back-
flow preventer and leads to increased wear.)
Tighten hose clamp.
Pull the mains connection cable of the pump through the
cable duct.
