Before starting up, check that the pump is properly primed; fill it completely with clean water by means of the hole provided after having removed the filler cap on the discharge body. This ensures that the mechanical seal is well lubricated and that the pump immediately starts to work regularly. The filler cap must then be put back in place. Dry operation causes irreparable damage to the mechanical seal and the stuffing box seal; - the auxiliary circuits have been correctly connected; - all the moving parts have been protected with suitable safety systems; - the electrical connection has been made as indicated previously; - pump-motor alignment has been correctly performed. We recommend you read the instruction manual of the KDN (also available in our DNA software) for all information on the product.

Switch on the power and check that the motor is turning in the right direction, that is clockwise when viewed from the fan side. This check must also be performed after having fed the pump, activating the main switch with a fast start-stop sequence. If the motor is turning in the wrong direction, invert any two phase leads, after having disconnected the pump from the mains. We recommend you read the instruction manual of the KDN (also available in our DNA software) for useful information for all information on the product.
