What Your Reverse Osmosis System Will Do

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 meas
ured in water as total dissolved solids (TDS).

The system includes replaceable pre and postfilter sedi
ment-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.

Plan Your Installation

PLAN YOUR INSTALLATION

It is recommended to read through the entire manual
before beginning your installation. Follow all steps exact
ly. 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.

NOTE: For best system performance, the feed water to
the system should be softened or less than 10 grains
per gallon hard.

The postfilter reduces any tastes and/or odors that may
remain in the water, after passing through the RO mem
brane, 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 fin
gertips eliminates the need to buy bottled water. The
storage tank holds over 2 gallons of RO product water
for your needs.

Tools Needed

UNDER THE SINK EOCATION

The Reverse Osmosis Filter Assembly and storage tank
are normally installed in a kitchen or bathroom sink cab
inet. See Figure 2.
A suitable drain point is needed for reject water from the
Reverse Osmosis filter.

REMOTE EOCATION

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

step 1 - Install Supply Water Fitting

CHOOSE TYPE OE WATER EITTING TO INSTATE

Locate the cold water line in the sink cabinet. It is recom
mended, 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 com
pression 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 fit

ting 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 plumb
ing code 248-CMR of the Commonwealth of
Massachusetts before proceeding with the installation.

INSTATE 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.

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 possi
ble leaks.

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 cop
per tubing or plastic pipe.

IMPORTANT: Before starting, close the hot and cold

water shutoff valves (See Pigure 5).

2. If installing on iron pipe, drill a 1/8" hole for the pierc

ing 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-clock
wise) 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.

step 2 - Install RO Under Sink

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 installa
tions. 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 plumb
ing 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 posi

tion). 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 con
necting fitting.

7. Tighten all connections, but do not over tighten plastic
connections.

Under The Sink Installation

Single trap

IMPORTANT: Locate drain adapter so when the black drain tube

from the Reverse Osmosis Faucet is installed later on,
it will make a straight run to the adapter, without
dips, loops, low spots or kinks.
