pump.
• Prior to assembly, all construction and connection measurements
should be checked and compared with the dimensions of the sys-
tem. Here you should pay special attention that the constantly

4.3 HYDRAULIC CONNECTION
NOTICE
The pumping station must not be used as a control
point for piping.
Prop up the pipes upstream from the pumping station.
Make connections without constraints.
Use suitable means to compensate for thermal expan-
sion of the piping.
4.3.1 Inlet
IMPORTANT
It is recommended that you mount check valves and stop valves on
the inlet pipes. These must be mounted so that they do not hinder
disassembly of the pumping station.
NOTE
All piping connections must prevent the propagation of noise and
The piping is supported.
1. Choose the connection openings to use.
Maintain a minimum slope of 3% on the inlet pipes to ensure proper
2. To connect the inlet pipes, saw the opening of the inlet pipe to be
used. The rear inlet of the double lift system must be opened with a

IMPORTANT
Preferably use the upper inlet.
If it is not possible to use the upper inlet, use the rear inlet located

NOTE
Using inlets lower than the 250 mm inlet can lead to dirt deposits in
the inlet lines and in extreme cases to blockage of the line. Therefore,
the higher inlet should be used whenever possible.

IMPORTANT
According to the recommendations of EN 12050-1, it must be
equipped with a vent above the roof. The pumping station must
