28CLEAN CHEMICAL FEED FILTER & FOOT VALVE:(If so equipped)Part of the optional Auto Fill & Chemical Feed system, the Filter & Foot Valve is on the end of the chemicalfeed hose that is placed in the chemical jug as part of the chemical feed system.Regularly examine the filter and clean as needed.To test the Foot Valve:• Remove the Filter & Foot Valve from the end of the chemical feed hose and rinse in fresh water.• Blow through the valve from the filter side of the barb.o If the Foot Valve is functioning, air should move freely from the filter side, but will not flow fromthe barb side of the filter.o If valve is not functional, clean or replace as needed.Heavy chemical build-up can be removed with a mild acid rinse and/or the use of a brush and compressedair.CLEAN VACUUM SHUTOFF ASSEMBLY SCREEN:Inside the recovery tank, on top of the stand pipe, is the Vacuum Shutoff Assembly. It functions to preventdebris and water from being sucked into the vacuum motors. Operating the MX3-500 without the VacuumShutoff Assembly or with a poorly maintained assembly will greatly decrease the life of the vacuum motorsand will void the warranty.If debris builds up on this filter, it will reduce the vacuum air flow and may cause a significant decrease in therate of water recovery. If debris prevents the float ball from moving or seating inside the assembly, it may notstop the airflow when the tank fill with water, and the water will be sucked into the vacuums and blown outthe exhaust. Use defoamer to prevent foam or moisture from entering vacuums (See Page 14).To clean:• Do not pull up on top of cap. Carefully pull up from the bottom of filter cap assembly to pull theassembly off of the stand pipe. Then pull float off of riser pipe.• Pull fibers and lint off and rinse filter cap assembly and float with clean water.• Place the float back on the riser pipe then push the filter cap assembly back onto the stand pipe andreplace the recovery tank lid.Flow DirectionFlow DirectionVacuum ShutoffAssemblyFilter & Foot ValvePDE100-11PChemical Feed HoseFilter Cap AssemblyVacuum Shutoff Float |
