NOTE
Pumping stations should not be installed near bedrooms and
living rooms (noise from the pumping station). (c section 3.11,
page 17)
Fitting the pumping station on anti-vibration mounts ensures
sufficient insulation against structure-borne sound with respect
to the pumping station.
Do not fit the pumping station in direct contact with the walls
to avoid transmission of the pumping station's vibrations.

4 .4 Pipe connections

4 .4 .1 Inlet pipes
wThe pumping station must not be used as a control point
for piping.
w Prop up the pipes upstream from the pumping station. Make
connections without constraints.
w Use suitable means to compensate for thermal expansion of
the piping.
NOTE
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.
✓ The piping is supported.
1. Choose the connection openings to use.
2. Cut the tip of the corresponding boss with a saw
NOTE
All piping connections must prevent the propagation of noise
and be flexible.
4 .4 .2 Discharge piping
Improper fitting of the discharge pipe.
Leaks and flooding of the installation room!
wThe pumping station must not be used as a control point
for piping.
wDo not connect other drain pipes to the discharge pipe.
NOTE
To prevent the risk of back-flow of water from the sewer, install
the discharge pipe in a «loop» so that its base, at the highest
point, is located above the back-flow level.
Fit a shutoff valve behind the check valve .
The check valves are equipped with a lever for emptying the
discharge pipe into the tank.
4 .4 .3 Ventilation pipe
Insufficient ventilation .
Risk that the pumping station will not work!
wDo not connect to a mechanically controlled ventilator
w Ventilation must remain free
w Do not block the vent outlet
w Do not install an air intake valve (diaphragm valve) .
According to the recommendations of EN 12050-1, it must be equipped
with a vent above the roof. The pumping station must always be ventilated
so that the tank is always at atmospheric pressure. The ventilation must be
completely free and air must flow in both directions (no diaphragm valve
fitted).
The vent pipe must not be connected to the vent pipe on the inlet side of a
grease trap.
Connect the ND 50 or ND 70 vent pipe (depending on the model) vertically
to the vent opening with the flexible couplings. The connection must be
smell-proof.

4 .5 Cellar drying

Automatic drying:
For automatic drainage of the installation room (in case a sump is installed,
for example), especially in case of risk of water infiltration or flooding, a
submersible pump for contaminated water must be fitted.

COMMISSIONING / DECOMMISSIONING

5 .1 Commissioning

5 .1 .1 Prerequisites for commissioning
Before commissioning the pumping station, make sure that the electrical
connection for the pumping station and all protective devices has been cor-
rectly performed.

5 .2 Application limit

Pressure and temperature limits exceeded .
Leakage of hot or toxic fluid!
w O bserve the operating specifications in the documentation.
w A void running the pump with the valve closed.
wDry running, without pumped fluid, must be avoided.
When in use, observe the following parameters and values:
Parameter
Max. allowed temperature
of the fluid
Max. room temperature
pH
Operating mode

5 .3 Starting frequency

To prevent engine overheating and excessive stress on the engine, seals and
bearings, limit the number of starts to 60 per hour.

5 .4 Commissioning with the control box

Operations required for commissioning
1. Perform a functional and sealing test of the pumping station: Once the
hydraulic and electrical connections are made, check the connections for
leaks by running water successively through each inlet used. Ensure the
device is operating properly and there are no leaks by performing a water
test and observing several start cycles.
2. Check the various points on the checklist (c section 7.4, page 20)
