3.4 Installation
Bottom section, complete floor/yard drain
A horizontal surface is made with compacted crushed
stone, gravel, etc. in the prepared excavations. The layer
thickness should be about 30 cm.
A layer of around 5-10 cm grit must be placed on the
compacted crushed stone, gravel layer in order to install
the full area of the bottom section (not if a complete
KESSEL System 400 floor/yard drain is installed).
If additional horizontal inlets are required, they must
be attached accordingly (see "Connection of additional
inlets", page 27) - (not if a complete KESSEL System
400 floor/yard drain is installed).
Place the bottom section or the complete floor/yard drain
on the prepared base of the excavations and connect the
inlet / inlets as well as the outlet. (If stoneware or cast
pipes are used, standard adaptors must be used).
Then align the bottom section or the floor/yard drain with
a spirit level and backfill the excavations with crushed
stone or gravel.
