Handling Handling Handling Handling
Use suitable equipment. Respect the accident-prevention regulations.
Lift and handle the product with care using suitable lifting equipment.
When you receive the pump, check the outside of the packing to ensure there is no
visible damage.
If the product shows signs of damage, inform our dealer within 8 days of delivery.
The product must be safely slung in order to be lifted and handled.
Do not use the eyebolts on the motor, if fitted, to move the whole pump; only use
them to move just the motor, if it needs replacing, after disconnecting it from the
pump.
This pump has been designed to be installed over the tank with the pump body immersed in the liquid.
The motor-pump support with delivery port includes the flange to be attached to the tank.
If necessary, the pump can be installed against a wall of the tank and positioned horizontally. In this case
make sure that the seal between the flange and the tank wall is watertight.
Immersion Immersion Immersion Immersion
To ensure proper operation and long-lasting efficiency, the immersion depth of the
pump body must not be less than the one shown in fig. 4.
6. 6. 6. 6. Electrical connection Electrical connection Electrical connection Electrical connection
Connection of the motor to the power supply must be executed by a qualified electrician in compliance
with current electrical standards.
Install a high sensitivity differential switch (0.03A) for extra protection against
electric shock in the event of inefficient grounding.
Make sure that the rated voltage is compatible with the line voltage.
Install a master switch between the mains and the electric pump. This switch must
be turned off before conducting any maintenance operations on the pump.
For easier motor connection the terminal board can be set in one of the four 90° positions shown in fig.
2.
To change the angle of the terminal board, in models with coupling (SVI….S .. and SVI….N…), remove,
whenever necessary, the coupling guard and loosen the 4 screws that fasten the motor to the spider,
turn the motor to the required position and re-tighten the 4 fastening screws.
To change the angle of the terminal board (at 90 or 120° for power up to 0.45 kW) in close-coupled
models (SVI…E..) please contact our Sales and Service Department.
Then remove the junction box cover and make the connections as shown on the inside of the cover as
well as in figs. 3 and 4.
Connect the ground wire first.
