3 Calculate the height of

the system chamber (D)

Now determine the required chamber depth for

underground installation or for installation in

the floor slab. Take the inlet depth from the top

surface of the cover to the bottom of the inlet pipe

from your drainage plan.

Height

of systems chamber

(Installation depth D)

Subtract the height of the system base (height

from top to the lower edge of the inlet) from the

inlet depth taken from the drainage plan and

you have the height of the required engineering

chamber. Now you can select a module with the

corresponding height and the required cover

from the article list. Please note the maximum

permissible total installation depth of 5.000

mm and the groundwater resistance of KESSEL

engineering chambers of 3.000 mm.

Note: check on-site max groundwater levels

4 Note: Connection pipe for

cables and ventilation

During planning, please also note the following:

• The maximum cable length is 30 m.

• Stipulate that the ventilation pipe and the cable

conduit must be laid with a continuous incline

(to allow water to flow back into the pump station).
