System Overview
The following information describes the components the are used in a typical foam system setup. Your application may not include all, or contain additional
components than the ones described below. Contact Waterous for more information.
Component/Accessory Component/Accessory Description Description
1 OIT or HMI The operator interface terminal (OIT) or a human machine interface (HMI) controls the foam system,
depending on your configuration. An OIT used with a traditional CAFS or a foam only (non CAF) system and
an HMI when you use it with a ONE STEP or an Eclipse GEN 2.0 CAFSystem.
2 OIT/HMI cable This cable connects the OIT or HMI to the control box.
3 Tank level sensor wire This wire connects the level sensor to the control box.
4 Tank level sensor This sensor alerts the operator when the supply reaches a predetermined level in the supply tank. It is
available as a horizontal or vertical mount.
5 Supply tank The supply tank contains the foam concentrate.
6 Tank shutoff valve The shutoff valve stops the concentrate from transferring into the supply hose.
7 Supply tank hose The supply hose transfers the concentrate from the supply tank to the pump.
8 Wye fitting with strainer The wye fitting with strainer traps debris that is in the concentrate.
9 Foam pump The foam pump transfers pressurized concentrate from the supply tank into the waterway.
10 Inject/bypass valve The inject/bypass valve directs the concentrate into the waterway, or removes it from the foam system.
11 Injector hose This hose transfers the concentrate from the pump to the injector.
12 Injector check valve This valve is installed in-line with the injector hose and prevents the concentrate from reversing direction.
13 Flowmeter sensor cable This cable connects the flowmeter to the control box.
14 Flowmeter tee The flowmeter tee measures the amount of water flowing through the waterway.
15 Master waterway check valve with injector This valve is installed in-line with the waterway and prevents the concentrate from reversing direction. The
injector is installed on the valve and directs the concentrate into the waterway.
16 Foam manifold The foam manifold is an assembly that contains a waterway check valve, injector and flowmeter.
17 Waterway supply line The waterway supply line is the line that is connected to the fire pump.
18 Foam solution The foam solution is the product created when the concentrate is combined with the water from the fire pump.
19 Bypass hose The bypass hose transfers the concentrate from the pump to an external container.
20 Drain line Drain lines are provided by the apparatus manufacture and are used to drain your system.
