By threaded tubes to screw directly on the oval
tapped counterflanges delivered with the pump.
The diameter of the pipe must never be smaller
than the one of the counterflange.
Limit the length of the suction pipe and avoid all
features that cause losses of head (bends, valves,
tapers...).
AUTION ! Connections has to correctly sealed:
C
No air entrance is allowed on the suction pipe
which is showing a mounting declivity (2 %)
(fig. 1).
Use supports or collars so that the pump does
not bear the weight of the pipes.
- The circulation sense of the fluid is indicated on
he identification label of the pump.
t
- Connect the non-return valve to the pump
discharge to protect it from hammer blow
effects.
To pump water with a large content of air or hot
water,we recommend installing the by-pass kit
(fig. 1).
5.3 Electrical connections
The electrical connections and the inspections
have to be done by a qualified electrician and
comply with the applicable local standards.
- The electrical characteristics (frequency, voltage,
nominal current) of the motor are mentionned on
the name plate).
- check if the motor it complies with the mains
supply used.
- The motors must be protected by a circuitbreaker set to the current mentionned on the
name plate of the motor.
- Provide a fuse disconnecting switch (type aM) to
protect the mains supply.
Supply network
- Use an electrical cable conforming with the
National Electric Supply Company.
Three-phase: 4 conductors (3 phases + earth).
If necessary, cut an opening in the terminal box,
fit the cable gland stuffing box and connect the
motor as shown by the diagram inside the cover
of the terminal box (fig. 4).
DO NOT FORGET TO CONNECT TO EARTH.
CAUTION ! A connection error would damage
the motor. The power cable must never touch
the pipe or the pump; make sure that it is sheltered from any humidity.
The electric motors used on the pumps can be
connected to a frequency converter. Strictly follow the instructions given by the data sheet of
the converter's manufacturer.
The converter must not generate voltage peaks
at the motor terminals higher than 850 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.
n the contrary provide a LC filter (inductance –
I
capacitor) between the converter and the motor.
It must be connected to the motor with a minimum length cable, armoured if necessary.

- Close the discharge valve (3),
- Open the venting plug (5), and the suction valve
(2) and completely fill the pump.
Close the venting plug only after water flows out
and complete air exit.
WARNING ! In hot water, a stream of water
may escape from the venting port. Take all
required precautions as regards persons and
motor.
Pump in suction
Two possible cases:
1st CASE (fig. 5-1):
- Close the discharge valve (3), open the suction
valve (2).
- Remove the venting plug (5).
- Unscrew the bottom drain-priming plug (6)
located on the pump casing 4 to 5 turns.
- Put a funnel into the venting plug port and completely fill the pump and the suction pipe.
- After water flows out and total air exit, filling is
complete.
- Screw the venting plug and the bottom drainpriming plug back in.
2nd CASE (fig. 5-2):
Filling can be made easier by fitting on the suction pipe of the pump, a vertical pipe fitted with
a Ø

D
To ensure that the pump is always primed,we
recommend to protect it with a pressure switch
or a float switch.
6.3 Check the motor sense of rotation
- With an open-end screwdriver placed in the slot
of the shaft on fan side,make sure that the pump
urns freely without sticking.
t
Three-phase motor
- Switch on the motor by short pressing on the
motor-overload release and check that it turns in
he direction indicated by the arrow located on
t
the identification label of the pump.
- In the opposite case and if the motor had three
phase, cross two phase wires on motor terminal
block or on the switch.
Single-phase motor
The single-phase motors and motors variatiors
are designed for operating in the correct sense of
rotation.
The sense of rotation is adjusted when assem
bling the product and is independent from the
network connection.
6.4 Starting
WARNING ! Depending on conveyed fluid and
running of pump, surface temperature can
exceed 68°C. Take necessary means to avoid
injuries.

. Maintenance
ANGER ! Before any operation, switch off the
D
pump(s).
o special maintenance in operation.
N
Keep the pump and the motor perfectly clean.
In case of prolonged stopping, if there is no risk
of frost, it is best not to drain the pump.
The bearing holding the coupling is lubricated for
its total lifetime and does not require any lubrication.
Motors
The bearings are lubricated for their lifetime and
do not require any lubrication.
Mechanical seals
The mechanical seal does not require any main-
enance in operation.
t
It must never operate dry.
Replacement frequencies
The replacement frequency of the mechanical
seal depends on the operating conditions of the
-
pump:
- Temperature and pressure of the conveyed fluid
for the mechanical seal.
- Starting frequency: continuous or intermittent
running.
The replacement frequency of the other components depends on the operating conditions of
the pump like load and ambient temperature.
CAUTION !
flow (closed discharge valve) for more than 10
minutes with cold water (T° C < 40° C) and more
than 5 minutes above 60° C.
We recommend to ensure a minimum flow of
about 10 % of the nominal flow of the pump to
avoid the formation of a vapour lock at the top
of the pump.
- Keep the discharge valve closed.
- Start the pump.
- Open draining plug to drain air. If no water leaks
within 20', close the plug and stop the pump,
then wait 20' to allow air to settle.
- Start again the pump.
- If necessary (particularly if the suction height
exceeds 5 m) repeat these operations.
- If water leaks at draining plug (it means the
pump delivers its pressure), slowly open the dis
charge valve. The pump has to be primed.
- Check pressure stability at discharge with a
manometer, if instability, perfect air draining.
- In case of failure, do the filling in again and start
the operation again.
- To perfect air draining, close the discharge valve
and the draining plug, then stop the pump 20',
start the pump again and open the draining plug.
Do it as long as air comes out.
- Open the discharge valve in order to have the
wished working point.
- Check that the current input does not exceed
the value indicated on the motor data plate.
The pump must not operate at zero
