Check that the supply voltage and frequency
correspond to the values stated on the nameplate.
Single-phase motors incorporate a thermal switch
and require no additional motor protection.
Three-phase motors must be connected to an
external mains switch and a motor-protective circuit
breaker.
Notes or instructions that make the job
easier and ensure safe operation.
Warning
The system in which the product is
incorporated must be designed for the
maximum pump pressure.
The default setting can be found in the
quick guide.
Warning
The electrical installation should be
carried out by an authorised person in
accordance with local regulations.
Warning
During electrical installation, make sure
that the power supply cannot be
accidentally switched on.
Warning
The unit must be connected to an
external mains switch with a minimum
contact gap of 3 mm in all poles.
As a precaution, the pump must be
connected to a socket with earth
connection.
We recommend to fit the permanent
installation with an earth leakage circuit
breaker (ELCB) with a tripping current
≤
30 mA.

Caution
Note
English (GB)
The ejector valve is supplied separate with the
pump.
Remove the plug (V), see fig. 1, and fit the ejector
valve into the hole.
The O-ring must be fitted to the ejector
valve.
Tighten the valve using fingers only.
Pos. 2
Turn the valve to the right (in).
Select pos. 2 when the pump has been primed, and
a large quantity of water and a low pressure are
required.

5.1 Ejector valve setting
The ejector valve in the plug hole (V) can be turned
to two positions. See fig. 3.
Figure 2 shows an example of how the ejector valve
position may affect the QH curve.

Pos. 1
Turn the valve to the left (out).
Select pos. 1 when the suction pipe is empty and the
pump is to be primed.
Select also pos. 1 when a small quantity of water and
a high pressure are required.

6. Start-up
Do not start the pump until it has been
filled with liquid. See the quick guide.
We recommend to fit a non-return valve
on the suction side of the pump.
6.1 Shaft seal run-in
The seal faces are lubricated by the pumped liquid,
meaning that there may be a certain amount of
leakage from the shaft seal.
When the pump is started up for the first time, or
when a new shaft seal is installed, a certain run-in
period is required before the leakage is reduced to
an acceptable level. The time required for this
depends on the operating conditions, i.e. every time
the operating conditions change, a new run-in period
will be started.
Under normal conditions, the leaking liquid will
evaporate. As a result, no leakage will be detected.
