ENGLISH
- The box delivered with the single-phase pumps allows the dry run
safety through a float switch adaptation (see § 6.3) or an on-off
control through a pressure switch connection (see FIG. 4).
- Control box suggested for three phase version allows the dry run-
ning protection by use of a float switch, also the automatic running
by pressure switch (see Fig. 5).
6.2 hydraulic connections
During the use of L pump, fill the section hose with
TTENTION!
water before starting the pump (see FIG. 8).
- The quason pumps are not self-priming.
- The pipework diameter cannot be inferior to the pump's one.
- In case of a semi rigid pipework the pump must be hung by a cable
fixed to the lifting ring situated on the discharge casing.
- The installation of a non return valve in pump outlet and before the
isolation valve is obligatory.

6.3 Electrical connections

W RNING! Electrical shock hazard
The electrical connections and the inspections have to be
done by a qualified electrician and comply with the appli-
cable local standards.
The power supply of the pump must include a circuit having
a residual current difference device (earth fault breaker)
acting at no more than 30 m .
In case of cord damaged, make it replace by a qualified
electrician.
- Control the kind of current and the network voltage.
- Observe the specifications of the pump nameplate.
DO NOT FORGET TO CONNECT THE E RTH.
- The three-phase pump is delivered with a 20 m long cable to be
connected with a protection mechanism or a connection box
(electrical connection: see installation and operating instructions of
the switching device).
- The motors must be protected by a circuit-breaker set to the current
mentioned on the nameplate of the motor. Provide a fuse discon-
necting switch (type aM) to protect the mains supply.
Nota : the single-phase pumps have an overcurrent protection, inte-
grated into the box.
- The pump with single-phase motor is cabled and delivered with a
capacitor box and a thermal protection. This box has to be
connected to the supply network with the cable provided to that
effect.
- Connection of a float switch or a pressure switch.
Disconnect the pump from the network before opening the
box.
Remove the strap and connect in its place the feed cable of the
on/off switch and the earth cable if provided.
Please refer to the terminal diagram inside the terminal box for
details of the electrical connection.
- Levels setting: to ensure that in off position, the water level is always
150 mm minimum over the suction sieve (see FIG. 3a).
7. ST RTING UP

7.1 Direction of rotation

Nota: The pressure measured at the borehole outlet with closed
valve corresponds to the head of the pump at zero output minus
the height between ground level and water level.
Single-phase 230 V : No reverse risk.
Three-phase 400 V : To determine the right direction of rotation of
the unit, to compare the delivery pressure, and bear in mind that
the right direction of rotation corresponds to the highest pressure.
Or by measuring the pressure, delivery valve closed and compare it
to the required one. In case of reverse direction of rotation, inter-
change the two phase wires inside the box or circuit breaker.
7.2 Operation
Never allow the pump to run dry or operate with
TTENTION!
the shut-off valve closed. The manufacturer's gua-
rantee does not cover damage to the pump caused by dry running.
- During the filling of the sump or installation of the pump in this one,
take care that the float switch can move freely.
- Once again check all the electric connections, electric protection,
rating of the fuse(s).
- Measure the current in each phase and compare with the nominal
values mentioned on the nameplate.
Do not exceed the nominal current of the motor.
- fter being submerged, the pump should be switched on and off
several times to allow it to be ventilated.
- It is necessary to realize a hole Ø 3 mm in the piping (see FIG. 3 -
item 13) to improve the air evacuation.
- Measure the power supply voltage with motor running.
Nota: See 5.2 for allowed tolerance.
8. M INTEN NCE
Isolate from power supply before checking the
TTENTION!
pump.
- The pump does not require particular maintenance.
- If the sieve is obstructed, the flow rate decreases significantly, you
must carry the pump back, dismantle the cover.
- The repairs on the pump and the modifications of the electric
connection will be realized by a specialist or a after sales member
only.
- It is advisable to mention the nameplate specifications at the time
of a spare parts order.
