2. Installation
2.5 Installation in high groundwater areas
(Sealing set Article Number 83023)
If the Aqualift F extends below the basement slab
into the ground, it is equipped with a perimeter
flange which can be connected to a waterproof
membrane. (See illustrations 9 and 10). As seen in
Illustration 8, the waterproof membrane is cut pro-
perly and placed over the base of the sealing flange.
The top flange portion is then placed over the flange
base and secured tight with the provided screws.
2.5.1 Installation in a membrane seals
basement slab
The waterproofing membrance can be connected
directly between the two flanges on the system
.
2.5.2 Installation in a waterproof concrete
basement slab
For this application the elastomer sealing mem-
brane (optionally available as spare part) should be
installed between the flange and the counter flange
and secured with the included screws. Before instal-
ling the membrane the pressure pipe connection
must be removed and then reconnected after mem-
brane installation is complete. Screws should be
tightened to a torque of 10 Nm. Any piping (such as
inlet piping or cable conduit piping) which penetrates
the waterproof concrete should be installed in a
completely watertight method.
