Step 7: Install the Filter Cartridges

While some models may have filter cartridges pre-installed, it's important to verify this in order to prevent permanent damage to RO
membrane upon start-up.
1) Using the filter-housing wrench provided with the RO System, unscrew the filter housing
sumps.
2) If not already installed, please remove the filter cartridges from their packaging, and insert the
filter cartridges into their appropriate housing sump.
IMPORTANT: Your RO System may be suitable for a variety of filter cartridges. Always ensure
that the appropriate filters are installed for proper pre-filtration.
3) Make sure that they slip down over the standpipe in the bottom of the filter housing sumps.
4) Verify that the o-ring is properly seated in the groove of the housing sump.
5) Turn the sumps, with the cartridges inside, back onto the appropriate cap – designated by the
corresponding label. Firmly tighten, but do not over tighten.

Step 8: Mount RO System

The mounting bracket of the RO System, has pre-drilled slots for easy mounting.
Depending on the location chosen, additional support may be needed to provide a
firm and solid mounting of the system. To allow for future system maintenance,
ensure there's at least 4" from the floor.
IMPORTANT: For basement installations, please see the APPENDIX at the end of this
section for additional information.
1) Using the bracket as a template, mark the mounting screw locations.
2) Drill 1/8" holes at each mark.
3) Install the screws and tighten them until the heads are about 1/8" from the
wall
4) Hang the RO System on the mounting screws and hand- tighten up against
the wall.
5) Keep the system in place while making the tubing connections.

Step 9: Make Tubing Connections

Complete all prior steps before making the tubing connections. The RO System has colored plugs inserted into the fittings for easy
identification of the system connections. Please reference "Getting to Know Your System" and "Flow Diagram" in an earlier section
to more easily identify the correct placement of tubing.
IMPORTANT: For basement installations, please see the APPENDIX at the end of this section for additional information.
When making tubing connections, follow these helpful tips:
 Attempt to keep tubing lines long enough to service the system later.
 Do not cut tubing at an angle. Cuts should be perfectly square.
 Insert tubing until it seats against stop inside of fitting. See "How to Make a Proper Quick Connect Tubing Connection" for more
information.
 Only remove colored plugs from the fitting when you are ready to make the connection. Make one connection at a time,
removing the colored plugs as you go.
Feed Water Connection (RED Plug)
1) Go back to the feed water valve you chose to install on the cold water supply line.
2) Using the coil of RED 1/4" tubing provided with the Parts Packet, connect one end into the feed water valve. Ensure
connection is secure.
NOTE: If connection uses a compression nut, it's recommended to use a 1/4" tube insert. The insert is pushed into the end
of the tubing, which supports it from collapsing.
3) Locate the Feed Water Inlet on your RO System. This should be identified with a 1/4" RED plug.
