2. Foam concentrate tank control valve should be in the CLOSED position (final installer valve or
FOAM-AUX CONTROL).
3. Following standard fire and foam system operating manuals and procedures, start the power source, engage the
fire pump, engage the hydraulic pump system PTO or power source and establish water-flow through all foam/
water solution discharges.
4. Manually OPEN the flush water supply valve from fire pump discharge or outside water source (see drawing)
or operate the FOAM-AUX function #3 to OPEN the electric water supply valve.
5. Turn ON the foam system (by using the Fury or Fusion display) and allow the hydraulic motor-driven foam pump
to operate.
6. OPEN all foam/water discharge valves
7. Auxiliary Functions—Final Installer Supplied System:
a) Operate the 3-way diverter valve “B” to the foam concentrate discharge outlet position
b) Operate the 3-way diverter valve “A” to ON, which diverts flushed water to the “B” diverter valve.
8. Auxiliary Functions: Foam Pro FOAM-AUX system:
a) FOAM-AUX display — turn on display and push Function #3 FLUSH
9. OPEN the external foam concentrate intake valve and CLOSE valve when clear water has been discharged
10. Continue to operate FLUSH SYSTEM until all water/foam discharges are flowing clear water and external
foam concentrate discharge flows clear water.
11. Operate the system for 5 to 10 minutes until all foam concentrate is ‘flushed’ from the system.
12. To shut-down the system:
a) Turn OFF the foam system on the display
b) Reduce RPM on power source, disengage fire pump, and hydraulic pump system
c) Close flush valve, or select the OFF position for the FOAM-AUX display
d) Disconnect potable water supply to fire pump
e) Let all water drain from discharges outlets, bleeder valves, and master fire pump drain system.
f) Restore all discharge adapters and caps.
Foam Line Intake Strainer Cleaning
The AccuMax II foam system has a in-line strainer, installed upstream of the specified foam pump. The function of
this strainer is to prevent debris or thick foam scum from entering the foam pump. The strainer requires periodic cleaning
of the internal strainer. As noted in the photos below, the strainer has a removable cap or plug for access to the strainer
assembly. This should be removed to wash the strainer assembly so that all debris can be cleaned out and then replaced.
The strainer should be cleaned every six (6) months, or after each major fire incident before being placed back in service.
