TFFT02598A
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 2.
Put pump operator's panel PUMP COOLER switch to OFF position (WP 0004). If
system air pressure is below 85 psi (586 kPa), start vehicle engine and allow system air
pressure to build to at least 85 psi (586 kPa) (TM 9-2320-347-10). Then shut off
engine (TM 9-2320-347-10). Open pump house panel A (WP 0539). While an
assistant puts pump operator's panel FOAM FLUSH switch to ON position (WP 0004),
check if foam flush valve operates to open position.
If foam flush valve does not operate to open position, go to Step 6.
Step 3.
While an assistant puts pump operator's panel FOAM FLUSH switch to OFF and back
to ON position (WP 0004), check if eductor valve operates to open position.
If eductor valve does not operate to open position, go to Step 5.
