NOTE
Ensure system air pressure is at least 85 psi (586 kPa) during this procedure. System air
pressure is required to activate valves.
Do not engage water pump engine during this procedure, except when performing
complete system checks. Valve operations can be checked without water pump
operation.
Valve operations can be checked by observing valve shaft rotation. Valves are open when
tabs or yellow paint tabs are aligned with direction of fluid flow.
Step 1.
Turn battery disconnect switch to ON position (WP 0007). If system air pressure is
below 85 psi (586 kPa), start engine and allow system air pressure to build to at least
85 psi (586 kPa) (TM 9-2320-347-10). Then turn engine off (TM 9-2320-347-10). Open
pump house access door A (WP 0539). While an assistant puts pump operator's panel
FOAM SYSTEM switch to on position (WP 0004), check if eductor valve operates open
position.
If eductor valve does not operate to open position, troubleshoot Foam Not
Delivered From All Systems (Bumper Turret, Ground Sweeps, and Manual
Metering Controls) or System Does Not Shut Off (WP 0094).
