5. Installation
5.1 Electric connections
The electrical connections and inspection
should be made by a qualied electrician and
comply with the standards in force.
Make sure that the electric installation is in com-
pliance with the standard IEC 364 and that the
line power supply has a highsensitivity 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 is delivered with a 3 wires cable equip-
ped with a standardised plug (2 poles + earth).
Connect obligatory the cable on a socket with 2
pole + earth.
5.2 Installation
Installation of a pump with monophase motor,
oat switch and optional overow audible signal.
The sump should be of ample size, so that the
motor does not start too often.
They operate automatically, when the oat swit-
ch switches the pump on from a certain water
level «h» and switches it off at a minimum water
level «h1».
In manual mode (oat switch in vertical position),
the minimal residual level is «h2».

ATTENTION!
• In continuous service: h1 min. = 240 mm
• Lower the pump into the sump using a chain
(or a cable) hooked to the handle, never by its
power 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 electric controls from frost.
5.3 Hydraulic connections
Discharge pipe 40/49 (1” 1/2).
The ball check valve must be connected to the
upper side of the discharge pipe before the full
bore isolation valve.
Provide a 4 mm diameter hole on the discharge
pipe (Fig. 1, item A) before the check valve for a
possible venting following a draining.

6. Starting
6.1 Filling - Degassing
• Fill up the sump.
• Check that the oat switch or the level regula-
tors operate freely.
6.2 Starting
• Make sure that the sump is full of water.
The pump must never run dry!
• Open the discharge valve,
• Start the pump.
• The functioning is now controlled automatically
by the oat switch or the level regulators.
7. Servicing
No special servicing while the pump runs but cle-
aning the impeller.
ATTENTION! Before any intervention disconnect
the pump.
