6. Assembly/Installation
6.1 Installation
– Fig. 1: Installation of a pump with monophase
motor, float switch and optional overflow audible
signal.
– Fig. 2: Fixed installation of 2 pumps connected to
a collector for twinned pumps and operating-
contol by 4 float switches.
NOTE:
Cut-out level:
For intermitted duty:
H min = 40 mm short-term,
For continuous duty:
H1 min = 230 mm (Fig. 1-2)
The shaft should be of ample size, so that the
motor does not start too often.
NOTE :
Lower the pump into the sump using a chain (or a
rope) hooked to the handle, never by its power-
or float switch cable.
Take care not to damage the power cable of the
motor during the going down in the sump.
Avoid placing the regulators near the outlet of
the pipe through which the water enters the
sump, since this could mover them.
Keep the lowest regulator away from the pump
suction port so that it will not be sucked in.
If the installation is outside protect the discharge
pipes, the isolating and check valve, and the elec-
tric controls from frost. Connect the cables to the
overload release or to the control box.
6.2 Hydraulic connections
– Diameter of discharge pipe (1 1/2")
– The non-return valve must be connected to the

7.1 Filling and venting
7.2 Starting
upper side of the discharge pipe before the full-
bore isolation valve.
– Provide a 4 mm diameter hole on the discharge
pipe before the check valve for a possible vent-
ing following a draining (Fig. 1-2, pos. B).
– Installation of twinned pumps to a collector,
connect each discharge pipes to a check valve
and an isolation valve (Fig. 2).
– Seal pipe connections carefully with appropriate
products.
WARNING! Electrical connection should be made
by a qualified electrician. Current national and
local regulations must be observed (e.g. VDE reg-
ulations in Germany).
– Make sure that the electric installation is in com-
pliance with the standard IEC 364 and that the
line power supply has a high-sensitivity earth
fault breaker (max. 30 mA).
– The electrical connections have to be done
before the pump is lowered into the sump.
– Check that the type, voltage and frequency of
the electric line power supply complies with the
indications mentioned on the name plate.
– The pump with monophase motor is delivered
with a 3 wires cable equipped with a standard-
ised plug (2 poles + earth). Connect obligatory
the cable on a socket with 2 poles + earth.
7. Commissioning
– Fill up the sump,
– Check that the float switch or the level regula-
tors operate freely.
– Make sure that the sump is full of water.
ATTENTION! The pump must never run dry. Dry-
running will damage the mechanical seal.
– Open the discharge valve,
– Start the pump,
– The functioning is now controlled automatically
by the float switch or the level regulators.
