4.2.2 Connecting the inlet pipe
All pipe connections must be flexible to reduce
resonance.
Install an isolating valve in the inlet pipe.
Many installations require an inlet below the standard
inlet 700 mm above the floor. You can fit a lip seal on
site. Use the following accessories:
Product number

91712026

Do not stand on the lifting station.
Make sure that the weight from the inlet,
outlet and vent pipes does not rest on the
tank. Long pipe sections and valves must
be supported.
The internal diameter of the inlet pipe must be the
same as the internal diameter of the inlet port.
1. Cut open one of the inlet ports to be used and/or
connect pipes to the second tank.
2. Fit the DN 150 socket seal in the inlet port or the
optional DN 160 socket if the bottom inlet is
chosen.
3. Insert the inlet pipe into the socket seal.
To facilitate maintenance and service of the
product, we recommend that you fit an isolating
valve between the inlet port and the inlet pipe.
Required size: DN 100 or DN 150.
