Maintenance
Cartridge Replacement

2. Close the tank shut-off valve.
3. Open the dispensing faucet to relieve system pressure. Close dispensing faucet when flow has stopped.
4. Remove the cover from the front of the system. Remove the retaining clip. Pull the cartridge off the system evenly at
top and bottom. Dispose of used cartridge.
6. Install the new cartridge, rocking gently from side to side as necessary until the cartridge tubes are properly engaged in
the unit connectors. Install the retaining clip, ensuring the slide locks snap into place in the slots. If the clip does not snap
easily into place through the slots it means the cartridge is not fully inserted into the connectors. Press the top or bottom of
the cartridge to engage the connector so that it snaps fully into place. Failure to properly install the retaining clip will result
in accidental leaks and flooding.
