Safety Information
Read through the safety information and operating instructions before using your Waterous Foam
Manager.
WARNING
!
Death or serious personal injury might occur if proper
operating procedures are not followed. The pump op-
erator, as well as individuals connecting supply or dis-
charge hoses to the apparatus must be familiar with
these pump operating instructions as well as other
operating instructions and manuals for the apparatus,
water hydraulics and component limitation.
WARNING
!
Pressure Hazard. May result in personal injury.
Prior to connection or removal of hoses, caps or other
closures with pump intake or pump discharge connec-
tions, relieve pressure by opening drains or bleeder
valves. Bleeder valves should also be used while filling
a hose connected to an intake with water.
WARNING
!
Scalding Water Hazard. May result in serious burns.
When operating the pump, be sure to open at least
one discharge valve slightly to prevent the pump from
overheating. If the pump runs for a few minutes com-
pletely closed, it may heat the water enough to scald
someone when the valve is opened. Overheating can
damage the packing, seals and other pump parts. If
the apparatus builder has installed a by−pass system
or other provision designed to prevent overheating,
opening a discharge valve may be unnecessary.
WARNING
!
Hose Pressure Hazard.
May cause serious personal injury.
Use only fire hose that is rated at 200 PSI or higher
working pressure.

Introduction
System Overview
NOTE: Read and understand the operating instruc
tions for the Foam Manager System prior to operating.
(Refer to Figure 1 for system components.)
The Foam ManagertSystem consists of an Aquist
Foam Proportioning System mounted on a Waterous CM
or CS fire pump.
Aquist2.5 Foam Proportioning System
The Aquis foam proportioner from Waterous delivers a
level of performance and reliability typically reserved for
more expensive Class A foam proportioners. Aquis 2.5
features a non-corroding brass body pump as well as
sensors that measure water temperature and water flow to
create the ideal water to concentrate ratio for superior
foam.
Foam Pump
The 12 or 24-volt, electric motor driven, positive displace
ment triplex plunger foam pump is equipped with an alu
minum crankcase, ball bearings, forged brass pump body
and manifold, solid ceramic plungers, stainless steel
check valves and piston guides, Buna packing and preset
thermal and pressure relief valves.
The foam pump is rated at 2.5 GPM @ 150 psi (9.46 l/min
@ 10 bar) with operating pressures up to 450 psi (32 bar).
Maximum electrical load of 40 amps @ 12 VDC and 21
amps @ 24 VDC.
A pump motor electronic driver, located inside the control
ler housing, receives signals from the microcontroller and
powers the 1/2 hp (.4 kW) electric motor in a variable
speed duty cycle to ensure that the correct amount of
foam concentrate set by the pump operator is injected into
the water stream.

AquistFoam Pump Operation
Upon power up, the software revision number will be dis
played. The unit will then display the flow rate.
The software will perform a linear interpolation to determ
ine values to use for flow rates that are in between flow
rates entered in the data array.
Figure 2. Operator Interface Terminal
IL3437
During normal operation, the OIT (Operation Interface Terminal) will display flow rate, percent mix, total water or total
product.
SELECT Selects data to display. The default is to display flow rate. Pressing the SELECT button will
scroll through the list, then wrap back around to the top of the list. The associated LED will
light to indicate what data is being displayed.
Flow Rate
Mix Percentage
Total Water
Total Product
Holding the SELECT button for more than two (2) seconds will lock the display to the current
position. Pressing the SELECT button again will unlock.
UP ARROW When the Mix Percentage is displayed, the current mix setpoint will be displayed. Sub
sequent presses of the UP ARROW button will increase the Mix Setpoint by 0.1%. After a ten
(10) second timeout, the display will return to the Flow Rate display.
DOWN ARROW When the Mix Percentage is displayed, the current mix setpoint will be displayed. Sub
sequent presses of the DOWN ARROW button will decrease the Mix Setpoint by 0.1%. After
a ten (10) second timeout, the display will return to the Flow Rate display.
Pressing both UP and DOWN simultaneously when the Total Water is displayed resets the
Total Water accumulator to Zero.
Pressing both UP and DOWN simultaneously when the Total Product is displayed resets the
Total Product accumulator to Zero.
Pressing both UP and DOWN simultaneously for two (2) seconds, when the Flow Rate is
displayed enters the MANUAL mode of operation. See Manual Mode operation below.
Pressing both UP and DOWN simultaneously while in Mix % will go to the preset default %.
FOAM Pressing the FOAM button will alternately start and stop the foam operation. When the con
troller is running, the FOAM LED will be lit. The FOAM LED will blink when the motor control
output is active.
MANUAL MODE If the display is showing the flow rate and the two ARROW keys are pressed simultaneously,
held for two (2) seconds, the % MIX LED will light and the display will show a default value of
2.0. Use the UP and DOWN arrow keys to increase or decrease this value in steps of 0.5.
NOTE: Pump output is based on a theoretical ratio of foam to water at 50 GPM.
Pressing both ARROW keys again exits the MANUAL mode and stops the pump.
While in manual mode, you can pause the motor by pressing the RED FOAM button (once).
You can increase or decrease the foam percentage at this time. Resume foam flow by press
ing the RED button once.
Pressing both ARROW keys again exits the MANUAL mode and stops the pump.
NOTE: Motor/Pump Assembly will operate in MANUAL mode whether or not there is a
water flow. If the INJECT/BYPASS valve is in the INJECT position, foam concentrate
will be injected into the system, which will waste foam concentrate.
AUTO RUN The system is equipped with an AUTO RUN feature. If the voltage (+12 or 24 VDC) is ap
plied to position 1 on the terminal strip, it will have the same effect as pressing the Red
FOAM button. This will start the Foam system. The system will not inject foam until water is
flowing.

Troubleshooting Guide
It is important to know what to do if your foam system in not operating properly. This troubleshooting guide should help
you diagnose, isolate and fix the problem encountered.
Problem Cause Fix
Poor foam solution (wet or dry)
Using wetting agent in place of foam Flush system and install Class “A” foam.
Lack of foam
Check if the Foam Pump is on. Check if there is
foam in the reservoir. Make sure the foam supply
valve is on and the Y strainer clean.
Foam in water system
Foam dumped into the water tank Flush water tank and pump until foam is cleared.
Foam cell is leaking into water tank
Condition applies to tanks utilizing a common
wall(s) between the foam tank and the water
tank. If a leak is confirmed, repair the foam tank
and flush the water tank and pump until foam is
cleared.
Foam proportioning manifold check valve mal-
function
If the above conditions have been corrected, the
final cause for foam in the water tank may be the
result of a malfunctioning foam manifold check
valve. To troubleshoot, cap off one foam dis-
charge that is plumbed to the foam manifold,
open that discharge valve and increase the
pump discharge to 30−40 PSI. Disengage the
pump and monitor the corresponding discharge
PSI gauge, looking for a drop in discharge pres-
sure. If the PSI drops, it indicates the foam man-
ifold check valve is leaking and requires repair.
Foam manifold drain plumbed into master drain Supply a separate drain for foam manifold.
