Filling an Empty DI Cartridge




Unscrew the cartridge cap and remove the foam ring


Pour the new DI resin into the cartridge and pack it down as hard as possible


Tapping the cartridge on a table will help settle the resin


Continue to add resin until level with the top and you are satisfied that no more resin will fit


Replace the foam ring inside the screw cap and on the cap


Replace the cartridge to the RO system making sure the arrow on the cartridge points up



Special Note: Properly filling a DI cartridge will ensure optimal performance by preventing RO water from channeling through DI Resin.
