CAUTION! When cleaning, monitor foam in the machine’s tank. Areas cleaned with other cleaning
equipment or chemicals may cause excessive foam to collect in the tank.
WARNING! EXCESSIVE FOAM IN THE TANK MAY CAUSE VACUUM MOTOR FLOODING AND MACHINE DAMAGE.
Pour one to two ounces of Defoam for use with these extractors directly into the tank or into the vacuum
hose while the vacuum is running. Defoamer for use with these extractors has been specially formulated to
work with this machine.
When finished cleaning, perform the daily maintenance procedure. Be sure that all filters are cleaned
thoroughly and replaced in machine. Leave lid off for drying.

9. Attach hose assembly to machine, connect fluid hose to the quick-disconnect found on the front of
machine and connect vacuum hose cuff to recovery inlet fitting.
10. Attach the desired tool to the valve end of the hose assembly.
11. Turn on vacuum and pump switches.
12. Turn on heater switch if desired. Heater only available with the ECO 500 AWH Series units.
13. Clean surface with tool attached to hose assembly.

shut off the vacuum motors. Should such case happen, drain the tank so the fluid level is much below the
high float switch.
