O-Rings
4. Install the Filter Cartridge
IMPORTANT! For the K-77686: Two identical filter cartridges are
used. For future filter cartridge replacement, replace both cartridges
at the same time to maintain proper performance.
Write the installation date on the new filter cartridge label.
Remove and discard the cap from the filter cartridge.
Inspect the filter cartridge for damage.
Verify that both sets of O-rings are present and are positioned
correctly in the grooves.
NOTE: The filter cartridge will only engage into the filter head one
way. Do not force the components.
Align the filter cartridge so the label is to the left, and press
upward so the filter cartridge key engages into the filter head.
Use your hand to rotate the filter cartridge counterclockwise 90°
until it stops and is securely engaged into the filter head.
