1- STORAGE AND HANDLING

Storage temperature: -15°C to +50°C. The non-packaged pump must be stored according to the diagram

in Fig.1 to prevent possible misalignment. The pump must not be exposed to direct sunlight.

Any operation required on the pump must be carried out by qualified personnel after

disconnection from the mains.

If the pump is not used in a vertical position, it must be handled with care and using the appropriate lifting

equipment in order to prevent damage (fig. 2).

2- USER

The submersible pumps for 4” wells offer a wide range of flow rates and heads making them ideal for water

raising, pressurisation and distribution in civil and industrial systems, for supplying autoclaves and tanks,

for fire-fighting and cleaning, for hobbies and for irrigation systems.

The pumps are designed to pump clean water, without solid particles or fibres, and not explosive liquids.

The maximum quantity of sand tolerated is 120 g/m3.

The metal and plastic components of the pumps are of the approved type for use with alimentary liquids.

3- CONNECTION OF THE PUMP TO A SUBMERSIBLE MOTOR FOR 4” UNASSEMBLED PUMPS

The pump can be coupled with a 4” submersible motor in compliance with NEMA regulations.

For correct assembly, proceed as follows (fig. 3):

Remove the cable cover (1) from the outer jacket of the pump (7) by unscrewing the fastening screws (2).

b) Ensure that the shaft, the joint and the coupling surfaces are clean.

c) Position the motor (3) vertically.

d) Connect the pump to the motor, aligning the “grommet” aperture of the lower support with the motor

cable output.

e) Tighten the nuts (4) on the tie rods (5), fixing the pump to the motor in a diagonal sequence with a

tightening torque of 16-20 Nm (inox) / 11-12 Nm (tecnopolymer).

f) Lay the motor cable (6) along the outer jacket (7), cover it with the cable cover (1) and secure it by

means of the screws (2).

4- OPERATING LIMITS

Maximum temperature of the pumped liquid: 40°C (O2-O3-OT), 30°C (H2-H3-HTF) • Maximum depth below

water level: 150 m (O2-O3-OT), 350 m (H2-H3-HTF) • Maximum number of starts per hour: 150 • Pro-

tection: IP 68 • Installation: for correct motor operation must be guaranteed a flow of water around the

motor casing of at least 8 cm/s • For use of the pump in swimming pools and garden pools, compliance

with the CEI 61-69 (EN 60335-2-41) standard must be guaranteed.

5- INSTALLING THE PUMP (Fig. 4)

The pump is designed to operate in a vertical or horizontal position.

You are recommended to fit a non-return valve on the delivery line to prevent water hammering; be careful

not to damage the supply cable when lowering it into the well and fasten it to the delivery pipe at intervals

of approximately 3 m.

5.a- Installation in the well

The pump can be lowered into wells with a diameter of 4” or larger. Ensure that the motor does not rest

on the bottom of the well and that the pump is fully submerged in the water.

Protect the pump from running dry by means of level probes if there is the danger of lowering of the water bed.

Dry operation will seriously damage the pump.

Never test the pump out of the water.

5.b- Installation in collecting tank or reservoir

To prevent damage, the tank or reservoir must be sized to avoid more than 150 pump starts per hour.

5.c- Suspension cord

You are advised always to use a steel or nylon suspension cord

MNE

SRB

fastened to one of the connection holes on the head whether using

plastic or metal delivery pipes.

6- ELECTRICAL CONNECTION

The motor must be only started by trained and expert personnel.

The electrical connections must be performed by expert personnel.

The O3-H3 PSC single-phase motors require a starting capacitor (Fig. 3a).

The proper capacitor type is shown on the rating plate on each motor.

On the O2-H2 2-Wire motors, the capacitor is already built-in.

For the correct electrical connection, refer to the rated values and the wiring diagram shown on the

motor rating plate, as well as the safety instructions described below. The following information only

refers to the motor and does not provide any indications on the control devices installed upstream.

Fuses and motor protection devices

1- An external switch must be fitted (Fig. 16) so as to be able to isolate system at any time;

2- An emergency stop device must be fitted;

3- Suitable fuses must be fitted for each phase;

4- The O2-H2 2-Wire motors (Fig. 5a), on the other hand, can be connected directly to the power supply

line, being fitted with a built-in motor protector; for the O3-H3 PSC motors (Fig. 5a) and OT-HTF

three-phase motors (Fig. 5b), a motor protector must be fitted in the control panel.

- By lacking of motor protection warranty expired;

- Motor protection in accordance with EN 60947-4-1;

- Trip time <10 s to 5 x In;

- Calibration at working current (max. In).

Earth connection

For the sizing of the ground connection, the power of the motor must be calculated according to IEC

364-5-54 and EN 60034-1

– The motor must be ground connected.

– Ensure the good contact of the ground wire connection.

It is recommended to fit lightening protection on the system control equipment.

7- SAFETY INSTRUCTION

Fig. 6, caution: carefully read the instructions for use, in particular the operating limits.

Fig. 7: please check that the tension and the frequency of the motor is correct for the power supply.

Fig. 8: the mains and earth connections must be made by qualified personnel.

Fig. 9: the pump is not suitable for pumping flammable or dangerous liquids.

Fig. 10: do not operate the pump dry. The pump must be fully submerged in order to avoid damage.

Fig. 11: you are forbidden to use the supply cable for raising the pump from the well or transporting it.

Fig. 12: all sand and solid particles must be bled from the well; the motor will not operate correctly if it is

partially or totally submerged in the sand.

Fig. 13-17: caution: the section of the electrical cable running downwards must be sized according to its

length and the current absorbed by the motor.

Fig. 14: caution: the pump can fall into the well. You are advised to use a safety cable at all times.

Fig. 15: use the pump within the limits of the Q-H rating plate specifications.

8- MAINTENANCE

Disconnect the pump from the mains before performing any repair or maintenance operation.

During normal operation the pump does not require any type of programmed maintenance.

You are advised to periodically check the pressure supplied and the current absorption.

A reduction in the pressure supplied may be due to wear of the pump whereas greater current absorption

indicates abnormal mechanical friction in the motor or pump.
