6. Start-up
6.1 General
Before start-up, it is vital that the unit is filled with the delivery
medium and ventilated. Close to the inlet nozzles of the pump,
it should also be the required minimum intake pressure.
The system can be ventilated via the pump. The pump itself
is self-ventilating.
6.2 Operational control
After switching on the power supply the pump must start up
independently: the Biral impeller turns and flashes green.
The pump runs according to basic settings
(see paragraph 7.8)
