3.6. Start-up

Once the connections have been made and before
running the pump the leaktightness of joints must be
checked. Switch on the water supply to the pump and
eliminate any air left inside the pump by using the
bleed devices on the pump.
Start up the pump. Press "Start" on the electrical
panel and press the pneumatic pump-start button.
The pipe valves must be fully open during
!
pump operation and must never be closed
while it is running. Shutting off or quickly
reducing the passage of water can give rise
to pressure surges that could lead to
equipment breakage.
Leave the pump running for a few minutes and check
that the equipment has been correctly installed.
