Using Your Filter Cartridge: Installation & Maintenance Tips
- Check your setup: confirm you have an Ace PNP (Swing & Twist) undersink system installed. If not, choose the with bracket option for a fresh install.
- Flush before use: run water through the cartridge before first use (or after long inactivity).
- Turn off the water: shut off your cold-water supply before changing cartridges.
- Remove the old cartridge: Swing & Twist to release it. The system’s shut-off helps stop the flow when removed.
- Install the new cartridge: align and Twist-lock firmly by hand (no tools needed).
- Turn water back on: check for leaks, then flush again for a few minutes until the water runs clear.
- Set a reminder: replace at 6 months or 1900L (whichever comes first), or sooner if taste/flow changes.

- Use on cold water only (do not connect to hot water lines).
- Replace filters on schedule to maintain water quality and flow.
- Store spare cartridges sealed in a cool, dry place until ready to use.
- A 350kPa pressure-limiting valve is required to protect your system.
