Installation instructions
Installation with lip seal (included in the delivery contents of the attach-
ment piece) In the case of floor constructions without sealing sheet, or
wherever the penetration of wastewater flowing back from the pipe into
the floor construction is to be avoided, the KESSEL lip seal must be
mounted between the attachment piece and the drain body or adapter,
in accordance with DIN EN 681-1.
The seal is pressed into the groove in the drain body. This prevents
the seal being pulled out when the attachment piece is adapted to
the required height..
Installation with seepage water
If seepage water is to be expected in extremely wet areas, for
example, the lip seal must be removed. This allows the seepage
water to be discharged safely between the attachment piece
and drain body or adapter into the drain.
Flexible level adjustment
The attachment piece can be tilted and has telescopic height
adjustment for adaptation to the floor level, and it can be turned
to match the tile pattern (1). Minimum installation height thanks
to sawing to size (2). The installation depth can be enlarged by
a maximum of 120 mm using a KESSEL extension piece (3).).
Fitting the pressure sealing flange (Art.-Nr. 48402)
When pressing the sealing sheets, the torques listed in the table
below must be heeded.
For installation in water load, the sealing sheet must have a thickn-
ess of at least 1.8 mm in accordance with DIN EN 18195-5.
Note: Max. load on pressure sealing flange and drain body is 70 kg.
Pipeline connection in accordance with DIN 19522
( ML pipe connection):
DN 50 70 100
DA 50 75 110
Construction debris cover
During construction work, the KESSEL floor/roof drain Practicus
can be protected against the penetration of dirt, e.g. mortar, con-
crete etc. using the construction debris cover provided
