Leave
all outlet valves closed.
z
Turn on stopcock and open inlet ballvalve, both pressure gauges on
inlet and PRV will start to show movement as the mains pressure fills the
system.
z
Check for leaks on all joints made.
z
Dependant on the incoming mains pressure the Mainsboost vessel will
start to fill with water.
z
Switch on the power to the pump, it will sense the pressure in the system
and if less than 3 bar will start to assist filling of the system.
z
Close Mainsboost vessel isolation valve
z
Allow the pump to continue running until air has been completely purged
from the system, all outlets will have to be opened and closed.

Once the system is completely full the pump will stop and only start again
if the Mainsboost vessel pressure drops below set point minus the differential
of the pump control.
