CORRECTIVE ACTION
FOAM FLUSH INDICATOR DOES NOT ILLUMINATE (PUMP OPERATOR'S PANEL)
NOTE
Ensure system air pressure is at least 85 psi (586 kPa) when operating foam flush valve
during this procedure. System air pressure is required to activate valves.
Do not engage water pump engine during this procedure. Valve operation 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 will ensure that foam flush system is operating properly or if fault exists in lamp,
indicator, or wires leading to indicator.
