Cartridge Replacement
A. Turn off water supply to filter. Depress red pressure-relief button on top of filter. Use
wrench to unscrew bottom of housing.
NOTE: If turning off water supply to filter will also turn off water supply to the rest of the
home, be sure to fill a bucket of water first to allow you to clean housing after it has been
removed.
B. Locate and remove large O-ring, wipe clean of lubricant and set aside. Discard used
cartridge. Rinse out bottom of housing and fill about 1/3 full with water. Add about 2
tablespoons of bleach and scrub cap and bottom of housing with nonabrasive sponge or
cloth. Rinse thoroughly. Lubricate O-ring with clean silicone grease. Insert O-ring back
into groove and smooth into place with finger. Insert new cartridge over standpipe in
bottom of housing.
C. Screw bottom of housing onto the cap and hand-tighten. DO NOT OVER-TIGHTEN.
Turn on water supply slowly to allow filter to fill with water. Depress red pressure-relief
button to release trapped air. Check for leaks before leaving installation.
NOTE: After installation, flush the cartridge for 10 minutes, wait one hour, then flush again
for 10 minutes before using the water.
