INTRODUCTION
A wrong utilisation and an inadequate manipulation of the pump will cause unsatisfactory
performances and early troubles. Therefore, please read this instruction manual carefully
before operating.
PRECAUTIONS BEFORE OPERATING
1. Power supply
Check the power supply voltage and frequency by referring to the identification plate on
the pump.
Operation of the pump on a different power voltage from the specified voltage will cause
impossibility of pumping up and motor burning.
2. Grounding
Make sure to connect the pump correctly to the earth. The earth-cable is the green and
yellow coloured one.
3. Rotation direction
As to the rotating direction, counterclockwise rotation viewing from the suction intake side
(lower side of the pump) is the correct way of rotating. The rotation direction is mentioned
on the identification plate of the pump.
After connecting the pump, let it turn out of the liquid to be pumped for an instant, in order
to check the direction of the motor by observing the agitator. Attention, the agitator could
detach itself when turning in opposite direction.
You only need to invert two of the three alimentation wires whenever the electric motor
turns in the wrong direction.
Rotation without being submerged for a longer period of time causes damages to the
seals.
The rotating direction of the agitator can be verified instantaneously.
Never drive the pump in opposite direction, as this causes early damages to the pump.
4. Protection of electric motor
In any case, it is necessary to protect the pump with a correctly calibrated thermal
protection to avoid any overload and to install a start-stop switch.
Pumps going up from 15 HP and more will have to be set up with a reactor starter box.
The supplier of the pump can advise you the adequate material.
