INSTALLATION & USE
Q-Series Twist-Off Replacement
- Verify you have an existing Omnipure Q-Series head with 1/4" Quick-Connect, 1/4" NPT, or 3/8" NPT fittings installed in your system.
- Twist the old Q5540 filter counter-clockwise to disconnect from the head. The T40 valve will automatically shut off water supply during removal.
- Align the new Q5540 cartridge with the head and twist clockwise until fully seated and locked.
- Flush the filter for 3-5 minutes to remove carbon fines and activate the media before normal use.
COMPATIBILITY
Applications & System Requirements
The Q5540 requires an existing Omnipure Q-Series head and works in ice makers, refrigerators, beverage equipment, drinking fountains, under-sink systems, and reverse osmosis pre- or post-filtration stages. The twist-off T40 design simplifies replacement in tight spaces without shutting off supply lines. This filter is ideal for municipal water applications where chlorine removal and taste improvement are priorities.
🔧 Pro Tip: The T40 twist-off valve lets you replace the filter without turning off your main water supply, but always keep a towel handy for residual water in the housing. Replace annually or when you notice a decline in flow rate or taste.
