- Remove Cartridge: Twist the existing 4HC‑H cartridge counterclockwise until it releases from the manifold head.
- Install New Cartridge: Insert the replacement 4HC‑H cartridge into the manifold and twist clockwise until secure.
- Flush System: Turn the water supply back on and flush at least 5 gallons of water through the new cartridge to remove carbon fines and air bubbles.
- Check For Leaks: Inspect all connections and fittings to ensure there are no leaks before resuming normal operation.

FAQ
Q: What Ice Machines Are Compatible with the H9320‑51?
