FOR SAFETY: Before leaving or servicing machine, stop on level surface, set parking brake (if so equipped), and turn off machine.

The water conditioning cartridge is required to be replaced when it reaches its maximum water usage or expiration time of when the cartridge was activated, which ever comes first. The ec-H2O system indicator light will blink green/red when it’s time to replace cartridge.

Depending on machine usage, on average, a new cartridge can last anywhere from 12 months for heavy machine usage to 24 months for light machine usage.

ATTENTION: During first time use and after replacing the water conditioning cartridge, the ec-H2O system will automatically override the selected solution flow rate for up to 75 minutes.

Lift the solution tank and remove the front cover from machine to access the cartridge. Drain solution tank before lifting.

Disconnect the two hose connectors from cartridge by pressing the gray collars inward and pulling the connectors outward. Lift cartridge to remove.
