Installation and Operation Manual
System 2000
Simulated Flow Operation
The Simulated Flow function of the system allows the
operator to control the foam pump manually. The water
flow rate and the concentrate injection percentage
rate can be set by using the display readout and the
rate adjustment buttons on the Digital Display Control
Module. This function provides the manual control
requirement of NFPA. This function also allows the
operator to empty the foam concentrate tank for
cleaning or changing foam types. It also provides a
means of checking the operation of the foam pump at
all normal rates of flow and injection without running the
water pump.
Warning: When operating the FoamPro in the
Simulated Flow function, an outlet for the foam
concentrate injection 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.

How to Display Action
1. Make sure the lamp below
FLOW is illuminated. Press
both the
and buttons at
the same time. The FoamPro
Display will read to the
left of the flow, meaning the
system will “simulate” the
displayed water flow rate.
(The default value of flow
may be set to any value, see
Section 11).
CAUTION: Be certain that an
outlet is provided for the foam
concentrate when the foam
pump is started.
2. Press the SELECT button

2. Change the injection rate
while in Simulated Flow
Function.
3. Change the Simulated Flow
Rate while in the Simulated
