INSTALLATION

If the system is used for the domestic water supply, respect the local regulations of the authorities responsible for the
management of water resources.
Choosing the installation site verified that:
- The voltage and frequency on the pump's technical data plate correspond to the values of the power supply system.
- The electrical connection is made in a dry place, far from any possible flooding
- The electrical system is provided with a differential switch with I Δn ≤ 30 mA and that the grounding system is efficient.
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.
For installation in tanks and tanks is strongly recommended the vertical
position and immersed in water.
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 meters along the delivery pipe.
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.
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 can operate partially submerged. 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.
