4.3 Deeper installation and waterproofing layer
A
With deeper floor slab installations, an additional extension section (Art. no. 83070)
must be fitted between the upper section and the tank (fig. A). A maximum instal-
lation depth of 650 mm to the top surface of the functional unit (e.g. the pump)
should be observed for the installation in the floor slab. This way, the necessary
parts can be reached for maintenance and servicing.
Art. no. 83075 should be used (fig. B) for waterproofing layer against water pres-
sure (e.g. with waterproof concrete).
