Step 1: Select an Installation Site
This RO System was designed compact enough to fit under most kitchen sinks. However, the RO System may easily be installed in a
basement, closet, crawl space, or wherever it's most convenient. If a basement installation is selected, note that additional tubing,
hardware, and fittings may be needed, and that a hole must be made from inside the cabinet through the floor to the basement.
When determining the best location to mount the RO System, there must be access to a cold water line and a drain line. Never
install in an area of the home where temperature is freezing as it may result in damage to the system. The water storage tank may
weigh over 35 pounds with a 4 gallon tank, when full of water. Be sure to place it on a firm, level surface.
The exact placement of the RO System and its accessories will vary with each installation. The installer and customer must
coordinate together on determining the most convenient placement of the dispenser faucet, RO System, and storage tank.
Always consider easy maintenance and servicing when choosing an installation site. It's recommended to mount the RO System at
least 4" off the ground. This will allow ample room to remove the filter housings. However, if the mounting wall is not solid, the
system may sit on the floor with screws used to keep it against the cabinet/wall in a vertical position.
Consideration for an ice maker or additional connections should also be made at this time. Extra routing, tools, fittings, and tubing
may be required.
IMPORTANT: For basement installations, please see the APPENDIX at the end of this section for additional information.
Step 2: Faucet Installation
When selecting a location for your faucet, be sure the stem of the faucet will be accessible for making all connections. Always take
special care and consideration if drilling a new hole for a faucet. We cannot accept any responsibility for damage to sinks or
countertops when you are drilling a hole for your dispenser faucet. The following are only guidelines to aid with the installation for
your dispenser faucet.
Under the counter installations generally require that the faucet be installed with the air gap module. In basement installations, the
air gap module can be eliminated only if one is provided elsewhere in the drain line.
NOTE: The Uniform Plumbing Code dictates that there must be an air gap between the RO line and the waste drain. It is the
responsibility of the installer to ensure compliance with all State and Local laws and regulations
IMPORTANT: For basement installations, please see the APPENDIX at the end of this section for additional information.
Drill Hole for Faucet
Most sinks are predrilled with a hole that's commonly used for a sprayer or soap dispenser. This could be used for a RO faucet
instead, with no need to drill a new one. However, if your installation site does not have a properly sized hole, or it's already being
used, an additional hole will need to be drilled. Always check below the sink to make sure nothing will interfere when drilling, and
that a 2" flat surface is available on your sink for mounting the faucet. The faucet should be aesthetically located, positioned to flow
directly into the sink, and able to swivel freely for convenience.
Drilling a Stainless Steel Sink
The faucet opening should be centered between the back splash and the edge of the sink, ideally on the same side as the
vertical drainpipe.
1) Mark the center and drill a 1/4" pilot hole.
2) Continue to enlarge hole with increasingly larger drill bits until the hole is 1/2" in diameter.
3) Smooth any rough edges and sweep away chips.
Note: Air Gap faucets require a 7/8" hole.
Drilling a Porcelain Sink
Porcelain sinks are extremely hard and can crack or chip easily. Always use proper tools and extreme caution when drilling.
1) Place a piece of masking tape over the area to be drilled to help avoid chipping.
2) Mark the center of the hole on the tape.
