Before starting the pump, make sure that it is completely immersed in water. 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! We recommend you read the Feka VS instruction manual (also available on our DNA software) for all information on the use of the product.
