3.1.1 Installation of the product in a frosty environment
Protect the product from freezing if it is to be installed outdoors
where frost may occur.
3.1.2 Ambient temperature during operation
The ambient temperature must not exceed 55 °C.
3.2 Mechanical installation
WARNING
Electric shock
Death or serious personal injury
‐ Switch off the power supply before you start any work
on the product.Make sure that the power supply cannot
be switched on accidentally.
CAUTION
Crushing of feet
Minor or moderate personal injury
‐ Wear safety shoes when handling the product.
CAUTION
Impurities in the water
Minor or moderate personal injury
‐ Before the pump is used for supplying drinking water,
flush the pump thoroughly with clean water.
3.2.1 Mounting the product
• Place the product in a horizontal position with a maximum
inclination angle of ± 5 °. The base plate must be facing

Ambient temperature
Up to 40
°C
The pump can run continuous operation.
The overheating protection ensures that the pump
runs intermittent operation when the air temperature
40 to 55
°C
is too high to cool the motor efficiently.
Example of intermittent cycle: the pump runs for 20
minutes and stops for 40 minutes before it starts
again. See the table below.

3.1 Location
3.1.3 Minimum space
Ensure sufficient space for service and maintenance and for motor
cooling.
• We recommend a clearance of 0.5 m on three sides of the
product.
• The motor is fan cooled, so do not block the fan cover.

3.2.3.1 Maximum system pressure
Make sure that the system in which the pump is installed
is designed for the maximum pump pressure.
The maximum inlet pressure depends on the head at the actual
duty point. The sum of the inlet pressure and the head must not
exceed the maximum system pressure.
TM072419
We recommend that you install a pressure-relief valve to protect the
pump so that the outlet pressure does not exceed the maximum
system pressure.
3.2.3.2 Inlet and outlet pipes
Please follow these general precautions when connecting the inlet
and outlet pipes.
Do not let the pump support the pipes. Use pipe hangers
or other supports at proper intervals to provide pipe
support near the pump.
English (GB)
TM064532
Fig. How to attach the lifting handle on the pump
3.2.3 Connecting the pipe system
Install the product so that it is not stressed by the pipe
system.
Pipe dimensions:
• The diameter of the inlet pipe must be larger than 1",
if the inlet pipe is longer than 10 m, or if the suction lift
exceeds 4 m.
• If a hose is used as inlet pipe, it must be noncollapsible.
We recommend that you install isolating valves on both
the inlet and outlet side of the pump.
1. Seal the pipe fittings with thread sealing tape or similar.
2. Connect pipes to the inlet and outlet port on the pump. Do not
let the pump support the pipes.
Use a pipe wrench or similar tool.
3. Fit a foot valve to the inlet pipe if the pump is installed above
the liquid level, for example if you pump from a well, tank or
reservoir. We recommend a foot valve with strainer.
4. We recommend that you install a filter on the inlet side to
protect the pump from sand, gravel or other debris if the pump
is to be used for pumping rainwater or well water.
5. Make sure that the inlet pipe has a gradual upward slope of 5 °
towards the pump to avoid air pockets, especially under
suction-lift conditions.
TM072480
The internal diameter of the pipes must never be smaller
than the diameter of the pump ports.
• Install the pipes so that air pockets are avoided, especially on
the inlet side of the pump.
• Use eccentric reducers with the tapered side down.
• Make sure the pipes are as straight as possible to avoid
unnecessary bends and fittings. We recommend long-radius 90
° pipe bends to decrease friction loss.
• Run the inlet pipe as direct as possible and, ideally, make sure
the length is at least ten times the pipe diameter.
• If possible, run a horizontal inlet line. We recommend a gradual
upward slope to pumps operating in suction-lift conditions, and
a gradual downward slope to pumps operating in positive inletpressure conditions.
Fig.
Recommended pipe installation to avoid friction and air
pockets
• A short pipe must be the same diameter as the inlet port or
larger.
• A long pipe must be one or two sizes larger than the inlet port,
depending on the length.
