DEIONIZATION CARTRIDGE MAINTENANCE AND REPLACEMENT
Materials Required:
Filter wrench and DI cartridges
NOTE:
In order to receive an accurate reading, the system must be producing water for at least 10 minutes before
reading the TDS meters.
Maintenance for MaxCap
®
DI Cartridge:
When the reading on the right-hand TDS meter (set to “IN”) displays 50% (or greater) of the reading on the left-hand
TDS meter (set to “OUT”), it is time to replace the MaxCap
®
DI cartridge.
1. Disconnect power to the system and shut down the water supply line.
2. Unscrew the third clear housing and insert the new Cartridge. Discard the old one to the trash.
NOTE: at this time leave the fourth clear housing empty.
3. Make sure the DI cartridge is installed in the correct direction as marked on the cartridge shell and be sure that
the top seal is securely attached to the top of the cartridge.
4. Tighten the cartridge housing by rotating it clockwise and hand tighten.
5. Turn the supply line back on, plug the power back in, and redirect the product water to drain. Allow water to run
through the MaxCap
®
DI Cartridge until the reading on the right-hand meter (set to “IN”) is “000”.
6. Check system for leaks.
NOTE:
When replacing DI cartridges, ALWAYS flush the MaxCap
®
DI with the downstream cartridge removed.
