INSTALLATION

Installation must be carried out by competent, skilled personnel in possession of the technical qualifications

required by the specific legislation in force. The term skilled personnel means persons whose training,

experience and instruction, as well as their knowledge of the respective standards and requirements for

accident prevention and working conditions, have been approved by the person in charge of plant safety,

authorizing them to perform all the necessary activities, during which they are able to recognize and avoid all

dangers. (Definition for technical personnel IEC 364)

The appliance may not be used by children under 8 years old or by persons with reduced physical, sensory or

mental capacities, or who lack experience or knowledge, unless they are under supervision or after they have

received instructions concerning the safe use of the appliance and the understanding of the dangers involved.

Children must not play with the appliance.

First of all, the power supply cable must be examined carefully, to exclude with absolute certainty the presence

of any damage. In particular, it must be checked that the cable has not been twisted, bent or crushed. Never

use the power cable to carry the pump or to lower it into the well. Lower the pump into the well using a

suspension cable. The end of the power cable must be protected from moisture. The installation depth of the

pump must be studied according to the dimensions indicated on the well drawing.

1. The pump can be lowered into wells with diameter 4" or

more.

The diameter of the well must remain constant to allow a

total descent without excessive pressure.

It is possible to install the pumps in tanks and cisterns as

long as the pump is always in a vertical position and

immersed in water. In case of horizontal installation,

consider the use of a cooling jacket.

2. The pump must be lowered into the well by means of a

nylon or steel suspension cable. No traction of any kind

must be exerted on the electric cable of the motor. The

electrical cable must be secured with plastic clamps every

two or three metres along the delivery pipe. In the case of

flanged delivery pipes, the flanges themselves must be

provided with recesses with well-rounded edges to

accommodate the cable.

3. If the delivery line consists of pipe sections screwed

together, make sure that they are safely tightened to prevent

the pipe becoming unscrewed by the torque force due to

motor kickback when starting.

4. Install the pump at a distance of at least 30 cm from the

bottom of the well in order to prevent sand getting into the

motor and the suction of impurities.

The pump must be completely submerged when operating.

If the water level is susceptible to frequent changes, the

system should be equipped with a water shortage protection

system to avoid the risk of dry running. When the pump is

installed in a borehole with a diameter slightly larger than its

own, make sure that the descent is not prevented by

obstructions.

ELECTRICAL CONNECTIONS

For the electrical connections, please refer to the SAFETY INSTRUCTIONS BOOKLET EN-60335-1

The mains voltage must be the same as that on the motor data plate.

Connect to the mains with a two-pole switch, with contact opening distance of at least 3 mm.

Correctly size the cross section of the power supply cable in relation to the length to avoid voltage losses.

Install a high-sensitivity differential switch (0.03A) as additional protection or compatible with the control

equipment (e.g. Inverter).
