Operational States (continued)
Operational State
Description
24-Hour Flush
A 24-hour flush occurs once the system has been in an idle state (no outlet flow) for twenty-four (24)
consecutive hours.
This is an automatic operation which does not require any additional action.
Dormant Flush
A dormant flush occurs once the system has been in an idle state (no outlet flow) for one (1) or four
(4) consecutive hours, based on the system settings.
This is an automatic operation which does not require any additional action.
Drain Cycle
The drain cycle opens all drain valves along with the flush valve and is used to drain the system
during service and/or maintenance.
This is a manual operation which is typically performed by a qualified technician.
Filter Flush
The filter flush cycle is intended to be used after replacing filters during routine maintenance. It is
designed to flush the air from the filters and prepare the system for normal operation.
This is a manual operation which is typically performed by a qualified technician.
High Inlet Pressure
Dump
A high inlet pressure dump opens the drain valves for 3 seconds in order to relieve excessive
(above 85 psi) internal or external pressure.
This is an automatic operation which will occur repeatedly if the inlet pressure is above the system
specifications.
High Outlet Pressure
Shutdown
The high outlet pressure shutdown turns off the pump and opens the drain valves to release
excessive internal pressure.
This is an automatic operation which will remain in effect until the outlet pressure is below 70 psi.
