4. START-UP INSTRUCTIONS

QUESTIONS PRIOR TO START-UP
• Before starting up the pump, carry out the following operations:
1. Open the pre-filter cover (See Fig.5).
2. Fill the pump with water through the pre-filter until it dips into the suction
tube.
3. If, during these operations the basket should have been taken out, do not
forget to replace it inside the pre-filter so as to prevent large particles from
entering the inside of the pump and thus blocking it
4. Check that voltage and network power corresponds to those indicated on
the pump specification board.
• Put the cover on the pre-filter and close it, without forgetting to place the joint in its
housing. (Fig.5)
• Under no circumstances should pumps work without previously having filled the
pre-filter with water. If this is not done, the mechanical joint could be damaged thus
producing water loss through this.
• In three-phase motors check that the motor rotation direction is correct, by means
of the fan located in the rear part of the motor, seen through the peephole in the fan
cover. (Fig.6)
• Check that the pump axle turns freely.
