1. GENERAL CONSIDERATIONS
The purpose of the instructions we provide is to give information about
correct installation and optimum performance of our pumps.
These are single-stage pumps for household pumping out applications.
The electric motor is cooled by the discharged water.
They are designed f or watering or the tr ansfer of w ater with solids in
suspension (maximum Ø of solids in suspension = 35 mm) from w ells,
tanks or swimming pools and at a maximum temperature of 35° C.
CAUTION. Correctly f ollowing the installation and use instr uc-
tions ensures good oper ation of the pump . Failure to heed the
instructions giv en in this man ual can lead to o verloading the
motor, underperformance of the technical char acteristics, redu-
ced pump life and other consequences of all kinds, for which we
decline all responsibility.
HAZARD, risk of electrocution. The pump must not be used in a
swimming pool while there are bathers in the w ater.
HAZARD.
Never put the hands or any other object into the suc-
tion or discharge mouth, as the rotating turbine can
cause serious injury/damage.
2. INSTALLATION
2.1 - Securing
The pump must be set upon a fir m and flat base. If there is mud or slud-
ge in the bottom of the tank, it is advisable to place the pump on a raised
base (a brick, for example), or to suspend it from a cable through the hole
in the handle provided for the purpose [Fig. 3].
Under no circumstances should it be suspended by the electrical cable or
by the discharge tubing.
The pump can be used in v ertical, horizontal or inclined position with the
discharge mouth at the top par t of the pump . On the automatic v ersions
with level float (v ersions A and N), ensure that the v ertical position is
maintained or that maximum inclination does not exceed 10° [Fig. 2].
On the automatic version, with level float (version A), if so wished the level
of water for pump star ting and stopping can be set b y sliding the float
cable by its hook. Check that the level float can move freely [Fig. 1].
The max. and min. water levels for star ting and stopping the automatic
pump of version N are specified in Fig. 4.
The maximum depth of immersion is 7 m.

2.2 - Fitting the impeller tubing
The pumps are supplied with connector for installation onto 1 1/2" gas pipes.
The weight of the tubes must not rest on the pump.
It is advisable to fit a check valve to prevent the tubes emptying.The check valve
must permit passage of the solids and must be designed to prevent blockage by
incrustations and deposits.
Ensure that the tube is not bent and that it is correctly fitted onto the outlet piece,
as an anomaly in either of these points can lead to incorrect attachment and
reduced output flow.
2.3 - Electrical connection
HAZARD. Risk of electrocution. The electrical installation must be
effectively earthed and must comply with the national regulations
currently in force.
The electr ical connection will be made b y plugging the po wer-
supply plug into a socket with the corresponding ear th contacts.
The protection of the system will be based on a high-sensitivity cir-
cuit-breaker switch (
The motor has b uilt-in thermal protection which disconnects the
power supply in the event of overload.
2.4 - Checks prior to first start-up
CAUTION. Check that the mains v oltage and frequency coincide
with those stated on the technical specifications plate .
Ensure that the pump is submerged [Fig. 2].
THE PUMP MUST NEVER BE OPERATED DRY.
3. STARTING THE PUMP
Open all the flow valves in the tubing.
Connect the plug into the mains soc ket. In the automatic v ersions
the pump will star t r unning as long as there is a suitab le level of
water. The water may take a few seconds to travel the entire length
of the tubing.
If the motor does not run, or if no water is extracted, try to trace the
fault through the list of the most common f aults and the possib le
solutions for them as set out in the pages which f ollow.
HAZARD. Contact with the rotating turbine can
cause serious injury/damage.
4. MAINTENANCE
For correct pump maintenance, follow the instructions below:
HAZARD. Risk of electrocution. Disconnect the pump from
the mains electricity supply before carrying out any repair or
adjustment work on it.
Under normal conditions these pumps are maintenance-free.
If the pump is to be left f or a length y per iod un used, it is
recommended that it be tak en out of the tank, cleaned and
kept in a dry and well-ventilated place.
CAUTION: In the event of fault, the electrical cable should be replaced
or repair work carried out on the pump only b y an authorised technical
service centre.
When the time comes to dispose of the pump , this equipment contains
no to xic or contaminating mater ials. The main components are duly
marked so that the pump can be selectiv ely dismantled to recycle the
materials.
