Tennant/Nobles - 4025507 - Cartridge, Ec-H2O Nanoclean Wcm, 270Ml (Replaces Tennant 9013646)

Tennant 4025507 is the ec-H2O NanoClean water conditioning cartridge, 270 mL (9.1 fl oz), also listed as 9013646. Tennant says it protects the plumbing from scaling, and it is used on ec-H2O NanoClean machines such as the 5680, 5700, T7, T300, T500 and T600 and the matching Nobles Speed Scrub models.

Typical cartridge life is 12 to 24 months depending on use, and the machine shows a code when it is due. Unused, it keeps for 1 year from the manufacture date on the label. After installing a new one, write the date on the label and reset the ec-H2O module timer. For up to 75 minutes afterward the system overrides your solution flow setting, which is normal.
