6. FOAM SYSTEM AUXILIARY FUNCTIONS
Final Installer Mobile System: Mobile System Auxiliary
Foam Functions
The foam system shall be supplied with “auxiliary function” components to provide several supplemental operations
of the foam system. This equipment can be provided and installed by the assembler of the system and/or certain assemblies
can be provided by Foam Pro as ‘optional’ equipment.
To assist the installer, the following section outlines:
1. OEM supplied and installed auxiliary foam functions
2. Foam Pro provided FOAM-AUX components and display system
“Simulation Mode”: Operating Foam System for Auxiliary Functions
The operation of the “simulation mode” is outlined in the SET-UP and OPERATION section of this manual. Careful
operator training and visible instructions must be in place for such operations. The “simulation mode” operation of a foam-
line-injector is required for OEM auxiliary foam operation. 1.5”/40mm size (for up to 150GPM/560LPM flow) or 2”/50mm
size for (300GPM/1125LPM flow) should be installed on FILs.
• It is extremely important all operators are trained in the operation of the “simulation mode” of a foam-line-injector. A
large instruction plaque shall be installed at the pump panel to denote the step-by-step set-up of this mode.
• When operating the FoamPro AccuMax System in the “Simulated Mode” function, an outlet for the foam concentrate
must be provided. Otherwise, dangerous excessive pressure may be built up in the apparatus water piping and/or hoses.
This outlet for the foam concentrate can be provided by turning the “CAL/INJECT” valve to the “CAL” position. A
suitable container must be provided to collect the foam concentrate. Or, The foam concentrate discharge or foam tank
refill line can be operated.
Final Installer Supplied: Auxiliary Foam Functions and Installation
The OEM supplied “Auxiliary Functions” could be as follows:
1. Valve and control of the foam tank-to-foam pump control valve (noted previously under INTAKE PLUMBING)
(Specify Size: _____inches/_____mm)
2. External foam concentrate intake valve (known as OFF-BOARD). Refer to section #15 on this installation.
(Specify Size: _____inches/_____mm)
3. Flushing of the foam system (Noted below)
4.
(*) If specified, foam tank refill system (Specify Size: _____inches/_____mm)
5. (*) External foam concentrate discharge control. Refer to section #16 on this installation.
(Specify Size: _____inches/_____mm)
6. Note: opening item #1 and #4 would allow the foam concentrate to be re-circulated.
Functions #4 and #5 (*) require special plumbing and installation of three-way valves to be installed AFTER the
foam-line-injector (FLI) assembly. These three-way valves shall be the same size as the FLI and shall be separately
controlled with an ON/OFF bypass switch and diverter control switch: foam tank refill or foam concentrate discharge
(open outlet – without cap). Refer to the drawing on a typical installation arrangement.
