Page 38 SmartFOAMWhen properly mounted, the flow sensor and checkvalve/injector fitting are on the side of the manifold and oneof the drain ports is on the bottom. The flow sensor shouldpoint upwards slightly to allow drainage of water andsediment. See Figure 19: Flow Sensor Tee PositionRange.OPTIONAL HALE PIPING COMPONENTSHale piping components, such as 3” (76mm) and 4”(102mm) wafer-type check valves, 115 and 2433 seriesflanges, mini manifold, etc. are available to simplifyinstallation of water and foam solution discharge piping.The arrangement shown in Figure 17: Typical MidshipPump Installation provides accurate proportioning acrossa wide range for up to four discharges from the minimanifold.The Hale mini manifold provides a 1” NPT tap forinstallation of the check valve/injector fitting.The Hale mini manifold and elbow components offer 4-3/8”diameter bolt circles and minimize fabrication and pipework. After installation, make sure all pipes, hoses andtubes are supported using the best industry practices.Figure 18: Typical 4 Inch Check Valve Installation(Midship Pump) shows a suggested installationarrangement using Hale 4” (102mm) check valves, pipeand Hale 2433 flanges.Figure 17: Typical Midship Pump Installation
