The horizontal installation of the group must be

specied to the oder,bearing in mind that:the

pump axis must be 0,5m over the bottom,the

air of the planet could easily evacuate,an ex-

ternal non -return valve must be installed.

ELECTRICAL

CONNECTION

After installing the unit check again the feeding

cable following the CABLE CONNECTION

instruction and connect it to the control panel

(1) that must be tted, according to the actual

rules, with:

• an omnipolar device for switching-off/sepa-

ration of the net(minimum opening contacts

3mm).

• a protection against short circuits (Am fuse)

and magnetothermics, rated in compliance

with the current plate.

• Possible devices against: lack of phases,

electric dissipations, lack of water, atmospheric

discharges and functioning-failure indicators.

ATTENTION

ALL THE ELETRIC MASSES MUST BE

CONNECTED TO THE EARTH OF THE

PLANET.

ALL THE CONNECTIONS MUST BE

EXECUTED ACCORDING TO THE LAW BY

QUALIFIED STAFF.

FIRST RUNNING

• With discharge gate (5) complitely opened

nomore air should leak from the pipings. Clo-

se almost complitely the gate and start the

electropump waiting for the exit of clean water

without air bubbles.Close the gate and control

on the pressure-gauge (4) that the maximum

pressure data corresponds to the one shown in

our catalogue,it not, revers the sense of rota-

tion of the motor only for three phase types.

• Gradually open the gate and run the pump

until clean water is coming out. If the well has

correctly been builted and previously bleeded,

clean water will come out in 15 min.

• During the previous instructions control voltage

ad current; admitted intermittent rush of current

of ±6% for voltage and current reffered to plate

data.

STANDARD RUNNING

Execute the hydraulic connection of the group to

the distributing plant,check during some working

cycles voltage and current data; if necessary

retouch the delivery,pressure and electric pro-

tection setting.

ATTENTION

• NEVER RUN THE PUMP DRY

CLOSED GATE FOR MORE THAN 2MIN.

• NEVER LET PUMP RUN IN THE OPPOSITE

DIRECTION FOR MORE THAN 30 SEC.

MAINTENANCE

Often control the plant trying to eliminate

disturbing causes such as sand, lime, ecc.

Keep efficient the parts exposed to dama-

ges (valves,lters,detectors and protections).

For interventions always call qualied techicians.

In case of long rests provide to often start the

electropump.
