Control vessel
Air Charge Pressure. The correct charge pressure provides reliable operation of the system and a prolonged
lifetime of the diaphragm. This should be checked regularly to avoid problems such as unstable pump operation.
1. To adjust air charge pressure: switch off the pumpset, release system pressure on water side by opening a
system outlet, and leave open. The water inside the bladder will be pushed back by the air charge pressure.
Remove cap on the filling valve, set air charge pressure refilling using dry air or nitrogen. Screw cap firmly on
filling valve. Close the system outlet. Close pumpset discharge valve, switch pumpset back on and slowly
open discharge valve to the system.
