2. Use the two mounting clips and snap them onto the existing filter. Position mounting clips at opposite ends

of the filter to hold the Specialty filter firmly.

3. Snap your specialty filter onto the mounting clips.

4. If your specialty filter has any plugs in the ports, please be sure to remove them before making tubing

connections.

5. Optional: Use the two ¼” elbows to connect onto the specialty filter if needed. Please note the elbows

connect to Quick Connect ¼” type of fittings
