Make sure that you turn off the power supply when connecting the cables of the pump
Please check the turning direction of three-phase motors following each connection. If this does
not correspond to the arrow on the motor two connections in the junction must be reversed.
Every motor must be permanently grounded.
Connections which do not conform to the above mentioned safety instruction are not
covered by the warranty.
Section 6
Servicing
The pumps are designed to operate for many years without servicing. If a failure does occur, it
most likely will be a moving part of the pump.
Always disconnect the power supply to the pump before servicing.
The replacement of the electrical motor must be done by a professional.
