On the version provided with a float switch, ensure that the float can move freely.
Ensure that the minimum dimensions of the borehole are as in the figure below. The dimensions of the borehole must also be calculated with relation to the quantity of water arriving and to the pump flow rate so as not to subject the motor to excessive starting operations. When the pump is to be in a fixed installation, with a float, a check valve must always be fitted in the delivery pipe. This is also advisable on pumps with manual operation.

The direction of rotation must be checked each time a new installation is made.
Proceed as follows:
Place the pump on a flat surface.
Start the pump and stop it immediately.
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:
Start the pump and observe the water flow rate.
Stop the pump, switch off the power and invert two phases on the supply line.
Restart the pump and check the water flow rate again.
Stop the pump.
The correct direction of rotation will be the one in which the flow rate and electric absorption are LOWER! The product manual available here on our site or here in our DNA software provides more information for this product usage and maintenance.

If the power cable is damaged in any way it must be replaced and not repaired (use cable type H07RN-F
diam. 9 – 9.5 mm. with minimum length 10 metres for the portable version, with a UNEL 47166-68 plug
for the SINGLE-PHASE version and with an EEC plug for the THREE-PHASE version).
This must be done by skilled personnel, in possession of the qualifications required by the regulations in force. The product manual available here on our site or here in our DNA software provides more information for this product usage and maintenance.
