Page 17: Operation
A typical venting allowance is 0.3 bar, added to the static height to give the cold fill pressure. The Differential setting represents the allowable pressure loss before the pump activates and restores the cold fill pressure. The Differential setting must not be greater than the system venting allowance. flowpress Direct O&M Manual... - Page 18 This will ensure that the system remains fully flooded during normal topup conditions. Once commissioned, the pressurisation unit should operate without any user intervention. Under normal operating conditions, the display will show the current system pressure in Bar. For an overview of the main operation screens, see image below. A clarification of menu icons, function and location can be found in Appendix 1: Icon library Home screen While the unit is filling, the display will show the current status of the unit and its actuators (valves).
