CAUTION
Failure to heed this warning involves a
risk of damaging the pump or the
installation.
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 pumping out water. The electric
motor is cooled by the discharged water.
They are designed for irrigation or transfer of clean water or water con-
taining few foreign bodies (maximum Ø of particles in suspension =
8 mm) from a well, tank or swimming pool at a maximum temperature
of 35
o
C.
CAUTION. Correctly following the installation and use
instructions ensures good operation of the pump.
HAZARD. Failure to heed the instructions in this manual can
lead to overloading of the motor, under-performance of the
technical characteristics, reduced pump life and other conse-
quences 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 water.
2. INSTALLATION
2.1. Securing
The pump must be set upon a firm and flat base or else suspended
from a cable or the like.
The pump can be used in vertical, horizontal or inclined position
with the discharge mouth at the top part of the pump [Fig.1]. On the
automatic versions with level switch (versions A and N), ensure that
the vertical position is maintained or that maximum inclination does
not exceed 10
o
.
If there is mud or sludge in the bottom of the tank it is advisable to place
the pump on a higher base (such as brick), or to suspend it from a cable
through the hole in the handle provided for the purpose [Fig. 2].
Under no circumstances should it be suspended by the electrical
cable or by the impeller tubing.
On the automatic version, with level float (version A), if so wished
the level of water for pump starting and stopping can be set by sli-
ding the float cable by its hook. Check that the level float can move
freely [Fig. 3].
together with the words "hazard"
The max. and min. water levels for starting and stopping the auto-
matic pump (version N) are specified in Fig. 4.
The maximum depth of immersion is m.
2.2. Fitting the impeller tubing
The pumps are supplied with 1 1/4" female gas thread in the impeller
section.
The weight of the tubes must not rest on the pump.
It is advisable to fit a check valve to prevent the tubes emptying.
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 inco-
rrect 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 natio-
nal regulations currently in force.
The electrical connection will be made by plugging the
power-supply plug into a socket with the corresponding
earth contacts.
The protection of the system will be based on a high-sensi-
tivity circuit-breaker switch (I n = 30 mA) together with a
multiple sectioning device with contact opening of at least
3 mm.
The motor has built-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 voltage and frequency coin-
cide with those stated on the technical specifications plate.
Ensure that the pump is submerged as shown in Fig. 1.
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 socket. In the automatic versions the
pump will start running as long as there is a suitable 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 faults and the possible
solutions for them as set out in the pages which follow.
4. MAINTENANCE
For correct 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.
IIf the pump is to be left for a lengthy period unused, it is
recommended that it be taken out of the tank, cleaned and
kept in a dry and well-ventilated place.
CAUTION: n the event of fault, the electrical cable should be
replaced or repair work carried out on the pump only by an
authorised technical service centre.
When the time comes to dispose of the pump, this equipment
contains no toxic or contaminating materials. The main com-
ponents are duly marked so that the pump can be selectively
dismantled to recycle the materials.
