5. INSTALLATION
Two standard cases:
• FIG. 1: Pump in suction
• FIG. 2: Pump under pressure from storage tank (item 9) or town
water supply (item 10), with dry-running protection system.
5.1 Installation
Install the pump in a place that is easy to reach, protected from frost,
and as close as possible to the place from which water is drawn.
For heavy pumps, provide a point of attachment (lifting hook, item
12) in the pump centreline to facilitate removal.
Install the pump on a concrete foundation block (item 13) at least 10 cm
high and attach by anchor bolts (for installation surface, (See FIG. 3).
Place an insulating material (cork or reinforced rubber) under the
concrete block to avoid transmitting noise and vibrations to the rest
of the installation.
Before final tightening of the anchor bolts, make sure that the pump
centreline is quite vertical; use shims if necessary.
Bear in mind that the altitude of the place of ins-

5.2 Hydraulic connections
Pump with oval flange pump casing: by threaded pipes screwed
directly into the tapped oval counter-flanges (supplied).
Pump with round flange pump casing: by pipes welded or screwded in
the counter-flanges (counter-flanges as accessories - See § 4.4).
Pump with rapide house coupling: with bracket, to be installed with an
end to fix on the hose (bracket and threaded as accessories - See § 4.4).

The diameter of the pipe must never be smaller than that of the
counter-flange.
Limit the length of the suction pipe and avoid all features that cause
losses of head (tapers, bends, valves, etc.).
Connections has to correctly sealed. No air entrance is allowed on
the suction pipe which is showing a mounting declivity (2%)
(See FIG. 1).
Use supports or collars so that the pump does not bear the weight of
the pipes.
An arrow on the in the identification label of the pump shows the
direction of fluid flow.
Pump under pressure: connect a check valve to the pump dischar-
ge to protect it from any ram effects.
Note: To pump water with a large air content or hot water, we recom-
mend installing the By-Pass (BP) kit (See FIG. 1).
5.3 Electrical connections
The electrical connections and checks must be made by a
qualified electrician and comply with applicable local stan-
dards.
For the electrical connections and starting of the motor varia-
tor fitted on MULTI-VE pumps, see specific electronic leaflet.
Refer to the motor data plate for its electrical characteristics (fre-
quency, voltage, nominal current). Check if the motor it complies with
the mains supply used.
The motor must be protected by a circuit-breaker set to the current
marked on the motor data plate.
Provide a fuse disconnecting switch (type aM) to protect the power
supply.
Line power
Use a electrical cable meeting standard board.
• THREE-PHASE:
4 conductors (3 phases + earth)
The position of the terminal box can be changed a quarter turn by
removing the motor attachment screws (if necessary, remove the
coupling guards) and turning the motor to the desired position.
Refit the attachment screws of the motor and the coupling
guards.
If necessary, cut an opening in the terminal box, fit the cable gland
stuffing box, and connect the motor as shown by the diagrams inside
the cover of the motor terminal box (or See FIG. 4).
A connection error would damage the motor. The power
cable must never touch the pipe or the pump; make sure that
it is away from any moisture.
The electric motors used with pumps can be connected to a fre-
quency converter.
Strictly follow the directions given by the manufacturer's data sheet.
The converter must not generate voltage peaks at the motor termi-
nals higher than 1000 V and dU/dt (Voltage/Time variation) higher
than 2500 V/µs. If the value of the voltage signal are higher than
those, risk of damage the motor are to forecast.
If it does, place an LC (inductance-capacitance) filter between the
converter and the motor.
It must be connected to the motor with a minimum length cable,
armoured if necessary.
DO NOT FORGET TO CONNECT THE EARTH.
6. STARTING UP
6.1 Prior cleaning
An hydraulic test is carried out for each pump in our factory.
If some water stays inside them. It is recommended for hygien
reasons to clean the pump before using it with potable water
supply.
