e) Pressure pipe
The pressure pipe is connected to the threaded joint G 1 ¼"(external thread). A non-return valve is already
assembled inside of the pressure joint. The pressure pipe must be guided through a backwater level locally
defined (see example of installation page 11)
f) Ventilation
The device is ventilated through a connection DN 50 (pipe Ø 50 mm) already installed. The supply cable is
also led outside through it. (The ventilation may also be separately guided outwards by assembling a 2
connection DN 50) (see example of installation page 11).
5.2 Fitting/commissioning
After assembling all pipelines, a functional test with tightness control should be effected.
After insertion of the mains plug, the unit is ready for operation so that the floating switch activates the pump
automatically with the inlet of water.
In the attachment piece available as accessory, the installation depth (tank: 432 mm) can be increased
continuously between min. 498 mm and max. 618.5 mm. (see installation example 11/12)
This attachment piece has the same reception for grid/cover plate and siphon as the basic tank. The sealing is
ensured using an O-ring.
By sawing the pipe, the installation depth in the above mentioned section can be varied and due to the
flexibility, every position of the attachment piece can be achieved.
Finally, the tank (and/or tank with attachment piece) will be grouted into the concrete bed.
