                                   5.     Installation and assembly

5.4   Routing connections
All feed and overflow pipes must be routed
with a decline of at least 1 % in the direction of
flow (possibly, subsequent settling must be
taken into consideration in this case). If the
tank overflow is connected to a public sewer,
this must be protected against reflux by
means of a lifting station (mixed sewer) or
reflux seal (pure rainwater sewer) according to                                                   >1%
DIN 1986.
All suction, pressure and control lines must be                     >1%
                                                       Kanal
                                                       Sewer
routed in an empty pipe, which must be routed
as straight as possible, without bending, to the
tank with a decline. Necessary bends must be
formed using 30° moulded sections.
Important: The empty pipe must be connected to an aperture above the max. water level.

                                                                          Domschacht
                                                                          Dome shaft
2.0 inch steps (see sketch). To allow the minimum soil covering of
the tanks of only 535 mm (21.1 inch), the telescopic attachment
must be slightly shortened.
The sealing ring is placed in the highest remaining complete              Dichtringring
                                                                          Sealing
groove and the telescopic attachment is pushed on (first lubricate
the sealing ring). The telescopic attachment must be well
supported with back fill material to ensure that it will not sink when
under load.
For assembling, the extension riser is placed loosely on the tank
opening. It gains its final stability without further fastening when
the pit is filled up and compressed.




6.2   Assembly of PE Cover
                                                                             Schraube M 8 x 60
The PE Cover must remain locked (child proof) in position                               screw

except when working in the tank.
