4.2 Deeper installation
For deeper floor slab installation, an additional extension section (art. no.
830070) must be inserted between the upper section and the drain body. For
installation in the floor slab a maximum installation depth of 650 mm up to the
upper edge of the function unit (e. g. pump) must be carried out. This way, the
necessary parts can be reached for maintenance and servicing.
