6.1. Start-up

ATTENTION

6.2. Electric board controls

Before starting the unit, verify that the motor shafts of the motor-driven pumps rotate
freely.
In case of three-phase motor-driven pumps, verify that the rotation direction
corresponds to that indicated by the arrows placed on the pump bodies or on the fan
covers; on the contrary, invert the connections of two phases of the electric power
supply cable.
Perform the full priming of the pumps by carrying out the following operations:
1. Loosen the cap on the intake collector.
2. Open all collectors motor-driven pumps connection valves.
3. Completely fill with water.
4. Close the cap.
5. Open the motor-driven pumps priming caps and carry out similar operation.
6. Close the caps and the flow valves.
7. Start the pumps from the electric board with manual control.
8. Slowly open the flow valves so as to eliminate the trapped air bubbles (if necessary,
stop the pumps and repeat the priming operation, to fill the spaces left empty by
the air).
9. Eventually repeat the manual start-up operations a few times for a short time to
allow the bleeding of the trapped air.
10. Completely open the flow valves and switch to automatic functioning of the
pumps, by acting on the selector switches on the electric board.
