CLEAN CHEMICAL FEED FILTER & FOOT VALVE:
The Filter & Foot Valve is on the end of the chemical feed 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.
oIf the Foot Valve is functioning, air should move freely from the filter side, but will not flow from the barb side of the filter.
oIf valve is not functional, clean or replace as needed.

CLEAN VACUUM SHUTOFF ASSEMBLY SCREEN:
Inside the recovery tank, on top of the stand pipe, is the Vacuum Shutoff Assembly. It functions to prevent debris and water from being sucked into the vacuum motors. Operating the M1200 without the Vacuum Shutoff Assembly or with a poorly maintained assembly will greatly decrease the life of the vacuum motors and 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 the rate of water recovery. If debris prevents the float ball from moving or seating inside the assembly, it may not stop the airflow when the tank fill with water, and the water will be sucked into the vacuums and blown out the exhaust. Use defoamer to prevent foam or moisture from entering vacuums.
To clean:
•Twist to loosen and pull the assembly off of the stand pipe.
•Pull fibers and lint off and rinse with clean water.
•Push the assembly back onto the stand pipe and replace the recovery tank lid.
