Filter Cartridge Replacement
(A) 1. Turn off water supply to filter.
2. Depress red pressure-relief button on top of filter.
3. Unscrew and remove bottom of housing.
(B) Locate and remove large o-ring, wipe clean of lubricant and set aside. Discard used cartridge.
Rinse out bottom of housing and fill 1/3 full with water. Add about 2 tablespoons of bleach and
scrub cap and bottom of housing with non-abrasive sponge or cloth. Rinse thoroughly.
Lubricate o-ring with clean silicone grease. Insert o-ring back into groove and smooth into place
with finger.
NOTE: This step is important to ensure a proper housing seal. Make certain o-ring is seated level
in the groove.
Insert new cartridge over standpipe in bottom of housing. Cartridges with one gasket should be
inserted with the gasketed end towards the threads of the housing. (gasketed end would point
upwards if housing is mounted as shown in illustrations).
(C) 4. Screw bottom of housing onto the cap and hand-tighten. DO NOT OVER-TIGHTEN.
5. Turn on water supply slowly to allow filter to fill with water.
6. Depress red pressure-relief button to release trapped air.
Check for leaks before leaving installation.
NOTE: A drinking water cartridge may contain carbon fines (very fine black powder). After
installation, flush the cartridge for 5 minutes to remove the fines before using the water. You
should run the tap at least 20 seconds prior to using the water for drinking or cooking purposes.
