TFFT03767
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 fluid flow.
Step 1.
Turn battery disconnect switch to ON position (WP 0007). 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). Shut off vehicle
engine (TM 9-2320-347-10). Push and release agent discharge button on roof turret
control handle (WP 0004), check if roof turret valve operates to open position.
If roof turret valve does not operate, go to Step 3.
