INSTALLATION
Note: Plumbing systems are always unique and may cause small deviations
in the factory calibration. It is recommended that the calibration procedure
be performed after installation.
Install Control Module
1. Measure and mark mounting location for control module panel cutout and
mounting screw holes. Make sure there is clearance behind the panel before
cutting holes. Refer to Figure 3 for layout and dimensions.
2. Cut out a 3.75-inch diameter hole and drill four holes for 10-32 mounting
screws.
3. Place the control module in position and secure with four screws.
Install Metering Valve Assembly and Eductor
Four (4) piping connections must be made. (Refer to Figure 4.) Recommended
interconnecting pipe diameters for FSA120 are 2.0" and for FSA015/030/060 use 1.5".
Note: It is important that the metering valve assembly and the eductor be
mounted below the bottom of the foam tank.
Note: The metering valve assembly must be mounted so that the motor
assembly is on top.
1. Connect the pump discharge to the eductor inlet (A). Reinforced hose may
be used. If the water flow to the eductor needs to be shut off, a valve may be
placed in this line. This valve should have a 2.0" (1.5" for FSA015/030/060 )
throat and should be at least six (6) inches away from the eductor.
2. Connect the metering valve assembly outlet to the eductor foam inlet (B).
Piping must have groove couplings.
3. Connect the pump suction to the eductor discharge (C). Reinforced hose
may be used.
4. Connect the foam tank to the metering valve assembly foam inlet (D).
Reinforced hose may be used. (The metering valve assembly inlet is the side
where the two foam flow sensors are located). The piping into the metering
valve assembly inlet must have a straight run of at least eight (8) inches. A
check valve must be placed in this line at least one (1) foot away from the
metering valve assembly inlet. A swing-check valve is preferred.
