INSTALLATION & USE
Installing Your K5520 Inline Filter
- Shut off water supply and relieve pressure from the system before installation.
- Connect inlet and outlet using 1/4" FPT threaded connections or 1/4" quick-connect fittings, ensuring flow direction matches any arrows on the filter housing.
- Turn on water supply slowly and check all connections for leaks, then flush filter for 3-5 minutes before use.
- Replace filter every 12 months or 2500 gallons, whichever comes first, or when flow rate decreases noticeably.
COMPATIBILITY
Where the K5520 Fits
This Omnipure K-Series filter works with reverse osmosis systems (as a post-filter), ice makers, refrigerators, beverage dispensers, drinking fountains, and under-sink filtration setups. The 1/4" FPT and QC fittings are standard in residential and light commercial applications. Note that 1/4" NPT threads measure approximately 0.540" in actual diameter, not 0.25" as measured with a ruler.
🔧 Pro Tip: When replacing your K5520, mark the installation date on the filter body with a permanent marker. Carbon block filters lose effectiveness gradually, so replacing on schedule ensures consistent chlorine and taste removal even if flow rate seems fine.
