The foot is positioned on the bottom of the tank and fixed with expansion screws of suitable dimensions. The pipe guide bracket must be
positioned at the top of well or borehole and inserted in the end of two 3/4” pipes (not supplied), which act as a slide. The two pipes connect
the bracket to the foot. Position the base bracket in contact with the pump suction strainer near the delivery aperture, secure everything to
the strainer cover with the screws provaided to lock the strainer cover.
Remove the top screw from the flange on the delivery side ( I ). Assemble the anti-rotation bracket ( G ). Replace the screw ( I ).
Extract the slide from the coupling foot and connect it to the delivery port of the pump.
Using the screw F and the nut H, fix the slide to the pump as indicated in the figure.
Reposition the slide/pump assembly on the foot (Fig.2).
5. ELECTRIC CONNECTION
Caution: always follow the safety regulations!
5.1 Single-phase motors are provided with built-in thermal overload protection and may be connected directly to the mains. N.B. If the motor
is overloaded it stops automatically. Once it has cooled down it starts again automatically without any need for manual intervention.
5.2 Three-phase pumps must be protected with motor protectors suitably calibrated according to the values on the data plate of the pump to
be installed. The plug on the pump must be connected to an EEC socket complete with isolating switch and fuses.
5.3 Do not damage or cut the power cable. If this should occur accidentally, have it repaired or replaced by skilled and qualified personnel.
6. CHECKING THE DIRECTION OF ROTATION (for three-phase motors)
The direction of rotation must be checked each time a new installation is made.
Proceed as follows (Fig.3):
1. Place the pump on a flat surface.
2. Start the pump and stop it immediately.
3. Carefully observe the kick-back on starting, looking at the pump from the motor side. The direction of
rotation is correct, that is clockwise, if the protection cap moves as in the drawing (anti-clockwise).
If it is not possible to check as described above because the pump is already installed, check as follows:
1. Start the pump and observe the water flow rate.
2. Stop the pump, switch off the power and invert two phases on the supply line.
3. Restart the pump and check the water flow rate again.
4. Stop the pump.
The correct direction of rotation will be the one in which the flow rate and electric absorption are LOWER!
7. STARTING UP
Models with a float switch start up automatically when the water level rises; models without a float are started by means of a switch located
upstream from the socket (not supplied).
Adjusting the float switch
Lengthening or shortening the cable between the float and the fixed point (slot provided in the handle - Fig.4)
adjusts the START or STOP level of the pump. Be sure that the float can move freely.

PRECAUTIONS
8.1 The intake strainer must always be in place during pump operation.
8.2 The pump should not be started more than 20 times in one hour so as not to subject the motor to excessive thermal shock.
8.3 DANGER OF FROST: When the pump remains inactive for a long time at temperatures of less than
32°F (
0°C
)
, it is necessary to ensure that
there is no water residue which could freeze and cause cracking of the pump components.
8.4 If the pump has been used with substances which tend to form a deposit, rinse it after use with a powerful jet of water so as to avoid the
formation of deposits or scale which would tend to reduce the yield of the pump.
