Tools Needed
Adjustable Wrench
Phillips Screwdriver
Drill & Drill bits, if required
Large Adjustable Jaw Pliers or Pipe Wrench
Flathead Screwdriver
Tape Measure
Your Reverse Osmosis (RO) Drinking Water System is a
water treatment unit. It uses household water pressure to
reverse a natural physical process called osmosis. Water,
under pressure, is forced through a semi-permeable
membrane where minerals and impurities are filtered
out. Clean drinking water goes to the faucet or storage,
while minerals and impurities are sent to the drain with
RO waste water. The minerals and impurities are measured in water as total dissolved solids (TDS).
The system includes replaceable pre and postfilter sediment-carbon cartridges. The prefilter reduces sand, silt,
dirt, rust particles, other sediments, and chlorine from
the water supply before it can enter the RO membrane.
The postfilter reduces any tastes and/or odors that may
remain in the water, after passing through the RO membrane, and just before going to the RO faucet. To prevent
water waste, an automatic shutoff valve closes when the
RO faucet is closed and the storage tank is full.
Your reverse osmosis system gives you a continuous
supply of sparkling clear, delicious water for drinking,
cooking and other uses. Foods will look and taste better
too. Having high quality RO product water at your fingertips eliminates the need to buy bottled water. The
storage tank holds over 2 gallons of RO product water
for your needs.
PLAN YOUR INSTALLATION
It is recommended to read through the entire manual
before beginning your installation. Follow all steps exactly. Reading this manual will also help you get all the
benefits from your system.
Your Reverse Osmosis Drinking Water System can be
installed under a sink or in a remote location. Typical
remote sites are a laundry room or utility room. Review
the location options below and determine where you are
going to install your system.
UNDER THE SINK LOCATION
The Reverse Osmosis Filter Assembly and storage tank
are normally installed in a kitchen or bathroom sink cabinet. See Figure 2.
A suitable drain point is needed for reject water from the
Reverse Osmosis filter.
REMOTE LOCATION
You can also locate the Reverse Osmosis Filter Assembly
and storage tank in a remote location away from the
Reverse Osmosis Faucet. You will need a nearby water
source and drain point.
See Figure 3.
CHECK SPACE REQUIREMENTS
Check size and position of items for proper installation
into location chosen.
TOOLS NEEDED
Review the tools needed list. See Figure 1. Gather needed tools before proceeding with the installation. Read
and follow the instructions provided with any tools listed here.

Step 1 - Install Supply Water Fitting
CHOOSE TYPE OF WATER FITTING TO
INSTALL
Locate the cold water line in the sink cabinet. It is recommended, but not required, that the cold water line be soft
water. You can use the saddle valve provided with your
unit to tap into the cold water line. See Fig. 5. Or you can
purchase standard pipe fittings locally such as a compression fitting. The fitting must provide a leak-tight
connection to the Reverse Osmosis 1/4" tube.
NOTE: Local code may dictate which type of water fitting is used. Consult a plumber if you are not familiar
with local codes or plumbing procedures.
NOTE: Codes in the state of Massachusetts require
installation by a licensed plumber and do not permit the
use of saddle valves.
If you live in the state of Massachusetts, review plumbing code 248-CMR of the Commonwealth of
Massachusetts before proceeding with the installation.
INSTALL SADDLE VALVE
(Included with your package)
This fitting will be installed on the cold water pipe. The
fitting must provide a leak-tight connection to the
Reverse Osmosis 1/4" tubing.
Complete the following steps to install the saddle valve
assembly.
1. Review Fig. 5 and familiarize yourself with all parts of
the saddle valve. This valve will self-tap a hole in copper tubing or plastic pipe.
IMPORTANT: Before starting, close the hot and cold
water shutoff valves (See Figure 5).
2. If installing on iron pipe, drill a 1/8” hole for the piercing pin.
IMPORTANT: If a battery-powered hand drill is not
available and an electric drill is used, ensure that the
drill is properly grounded.
3. Place the seal on the inside of Clamp X. See Fig. 5.
Turn the valve handle all the way out.(counter-clockwise) Be sure the piercing pin does not stick out
beyond the seal.
4. Place Clamp X and Z around the pipe. Secure in place
with two screws. Tighten both screws evenly. Do not
over tighten screws. See Fig. 5.
5. Turn the valve handle all the way in. (clockwise) This
will pierce the wall of the pipe. See Fig. 5.
Figure 5
6. Do not connect the tubing to the fitting at this time.
This will occur later in the installation.
NOTE: Once the saddle valve is installed, the nut near
the handle may need to be tightened to prevent possible leaks.

Step 2 - Install RO Drain Under Sink
Figure 6
Figure 7
Figure 8
INTRODUCTION
A suitable drain point is needed for the reject water from
the Reverse Osmosis Filter. You have two options to
choose from:
• Install the Drain Adapter included with your unit
See Figures 6, 7 & 8. This is used in under the sink
installations. The drain adapter kit is installed onto
your sink drain pipe above the P-trap. See Figure 6.
• Use another existing drain in your home
This is usually used in remote location type installations. The drain tube from the Reverse Osmosis Filter
runs directly to an open drain. See Figures 9 & 10.
NOTE: Local code may dictate which type of drain
installation is used. Other than local code, either drain
installation types may be used. Consult a plumber if you
are not familiar with plumbing procedures.
INSTALL DRAIN ADAPTER KIT
(Under sink Installation)
In an under the sink installation, you normally use the
P-trap drain adapter. A drain adapter kit is included in
your package. Review the drain adapter kit parts in
Figure 8. The drain adapter is always installed in the
sink drain pipe, above or ahead of the P- trap. See
Figures 6 & 8. Be sure to comply with your local plumbing codes. The drain adapter fits 1-1/2" sink drain pipes.
Other drain pipe fittings, purchased locally, may be
needed in addition to the adapter.
1. Slowly disassemble the sink drain pipe between the
sink P-trap and the sink tailpiece. See Figures 6 & 8.
2. Clean the sink tailpiece to assure a leak-tight fit.
3. Install drain adapter directly onto the sink tailpiece
using the ferrule and nut. Snug the nut, but do not
tighten. See Figure 7.
4. Assemble the drain tubing connector to the drain
adapter using the ferrule and nut. Snug the nut, but
do not tighten. See Figure 7.
NOTE: Locate so drain tubing from the Reverse
Osmosis faucet will make a straight run to the adapter,
without dips, loops, low spots or kinks. See Figure 8.
5. Turn the connector to about 45° (10:00 or 2:00 position). See Figure 7. Tighten the nut securely.
6. Assemble the P-trap to the drain adapter, and other
drain pipe fittings as required to complete the drain
run. See Figure 6.
NOTE: If needed, you can cut the unthreaded end of
the adapter to make it fit. Do not cut too short or the
adapter will not make a leak-tight seal with the connecting fitting.
7. Tighten all connections, but do not over tighten plastic
connections.
