CAUTION:
The Centers for Disease Control and Prevention (CDC) and the Environmental Protection Agency (EPA) have issued guidance to people with severely
weakened immune systems who may want to take extra precautions to reduce the risk of infection with Cryptosporidium from drinking water. This guidance
pertains to people with HIV/AIDS, patients receiving treatment for cancer, recipients of organ or bone marrow transplants, transplant patients taking
immunosuppressive drugs, and persons who have congenital immunodeficiencies.
The EPA has stated that they do not know the significance of drinking water compared to other possible sources of Cryptosporidium to determine how most
people become infected. The CDC-EPA guidance suggests that immunosuppressed individuals discuss their risks with their health care provider.
This drinking water system is tested and Certified by NSF International to NSF/ANSI Standard 58 for cyst reduction. It meets the NSF/ANSI standard of
reducing at least 99.95%* of cysts (including Cryptosporidium), however, because this is not 100%, immunosuppressed individuals should take the extra
precaution of boiling their drinking water. According to the CDC-EPA, bringing water to a rolling boil for one minute is the most certain approach for killing
Cryptosporidium.
All individuals should take adequate precautions when changing the filter cartridges, including wearing protective gloves, to avoid direct contact with the
exhausted cartridges.
*For complete specifications, refer to the Performance Data Sheet.

SECTION I. INTRODUCTION
Your new Reverse Osmosis (R.O.) Drinking Water
System uses a combination of filtration technologies
to reduce unwanted contaminants in a water supply.
The following steps combine to give you the best in
clear sparkling drinking water:
MECHANICAL FILTRATION/ACTIVATED
CARBON–The sediment prefilter will remove the
larger particles such as silt, rust and scale. Its
5 micron (equal to 0.0002 inch) nominal rating
helps to give maximum life to the R.O. Membrane.
The activated carbon in the Prefilter will remove
any chlorine that may be present in the feed water.
This pretreatment is also necessary for membrane
protection.
REVERSE OSMOSIS MEMBRANE–The R.O.
Membrane is the heart of the filtration system.
It is designed to reduce the dissolved mineral
content of the water. Minerals picked up in the
environment by the water are measured as Total
Dissolved Solids (TDS). In the Reverse Osmosis
process, dissolved minerals are separated from
the incoming water (Feed Water) to produce the
product water (the Permeate). The excess minerals
are rinsed to drain (the Reject Water).
The membrane is a specially constructed, fully
aromatic polyamide film and is classified as a Thin
Film Composite (T.F.C.).
The spiral wound construction of the R.O.
Membrane provides maximum surface area for
water production and is less susceptible to fouling
by particulate matter, turbidity and colloidal
materials.
ACTIVATED CARBON–The Activated Carbon
Post Filter contains carbon particles with a vast
network of pores. The tremendous surface area
of these pores (typically 800–1200 square meters
per gram of carbon) gives the carbon very good
adsorptive sites for substances that contribute to
tastes and odors.
IN–LINE ACTIVATED CARBON POST
FILTER–The In–Line Activated Carbon Post
Filter is located after the Holding Tank and
reduces the tastes and odors that may pass through
the system. It adds a final polish to the water.
AUTOMATIC SHUTOFF VALVE–The
ASO Valve senses when the product water tank
is full and closes the feed water supply to prevent
excess reject water from going to drain when the
unit is not producing water.
WATER QUALITY MONITOR–The optional
Water Quality Monitor has been integrated into

the system cover for instant monitoring at the
touch of a button. The monitor compares the level
of the total dissolved solids in the incoming (feed)
water versus the product water and calculates
the percent rejection. The monitor is preset to
indicate a level of 75% rejection.
NSF/ANSI Standard 58 requires a 75% total
dissolved solids rejection to pass the requirement
of the standard.
A green light indicates that the percent rejection
is at or above the set (desired) value and that the
system is producing quality water.
An amber light indicates that the product
water quality is less than acceptable. Because
the Water Quality Monitor was designed to
operate best while the system is making water,
a false reading may occur if tested when your
R.O. drinking water system is not making water.
Please empty the storage tank, wait 15 minutes
for the system to begin making water, and test
your water quality again. If the Water Quality
Monitor light is still amber, please contact a water
treatment professional for service. The Water
Quality Monitor requires a 9 volt battery, which
is included. Systems not equipped with a Water
Quality Monitor contain a water quality test kit.

19. Bicycle hand air pump.
20. Small bottle of liquid chlorine bleach.
21. Graduated measuring cylinder.
22. Paper towels, wisk broom and assorted clean up
materials.
C. Site Selection for Major System Components
The R.O. System was designed to fit under a sink,
however, because of space limitations or other
reasons, the system’s flexible design allows for
other locations. When determining the location
remember that access to a cold water tap line, the
household drain, and ease of filter replacement are
important considerations.
All components and tubing should be located
in an area which is not exposed to freezing
temperatures. If winter temperatures are severe, the
area should be above the minimum temperature
listed in Table B, page 5 for proper performance.
Do not expose unit or tubing to direct sunlight.
1. Dispensing Faucet–The faucet should be
placed near the sink where drinking water is
normally obtained. Convenience of use (filling
of water pitchers and glasses), and an open area
beneath the faucet under the sink for attaching
product and drain tubing are considerations.
A 2" diameter flat surface is required above
and below the installation site. The thickness
of the mounting surface should not exceed
1¼". Watch for strengthening webbing on the
underside of cast iron sinks.
2. Drinking Water Holding Tank–The Holding
Tank may be placed where it is convenient
within 10 feet of the faucet; under the sink or
in an adjacent cabinet are the best choices. If
a longer run of tubing is required, the tubing

7
should be the 3/8" diameter OD size to prevent
a high pressure drop. Remember, these tanks
can weigh up to 30 pounds when full of water;
a firm, level area is required.
3. R.O. Manifold Assembly–The manifold can
be installed on either the right or left side of
the under–sink area or a cabinet. The right
side is recommended because all the tubing
will be to the back of the cabinet and out of
the way. Installation in the basement is also
an option, one location is near the laundry/
utility sink where cold potable water and drain
access is handy. The mounting location should
allow adequate clearance and accessibility for
cartridge changes.
4. Feed Water Connection–The Feed Water
Saddle Valve should be located as close to
the manifold assembly as possible. USE A
POTABLE COLD WATER SUPPLY ONLY.
Softened water is preferred as it will extend the
life of the R.O. Membrane.
5. Drain Connection–The waste water must go to
drain through an anti–siphon air gap. The air
gap is provided for in the base of the faucet. If
discharging into a utility sink or standpipe, an
air gap of greater than 1" above the flood rim
must be provided.
Do NOT connect the system drain line to the
dishwasher drain or near the garbage disposal.
Backpressure from these units may cause the air
gap to overflow.
SECTION IV. INSTALLATION STEPS
All plumbing should be done in accordance with state
and local plumbing codes.
NOTE: Some codes may require installation by a
licensed plumber; check with the local plumbing
authority prior to installation.
In restricted under–sink areas, it may be easier to
install the faucet first. Allow adequate tubing lengths
for any final component position.
A. Faucet Installation–The faucet contains an
anti–siphon air gap. While the system is producing
water, the drain water flows from the R.O.,
through the air gap and then to the household
drain. The purpose of the air gap is to prevent
water in the drain from backing up into the R.O.
Drinking Water System.
NOTE: For proper installation the Air Gap
Faucet has a critical level line “CL”marked on its
body and should be mounted so that the “CL”line
is at least one (1) inch (26mm) above the flood
level rim of the sink.
The easiest installation is to use an existing
spray attachment hole. If the spray faucet hole is
not available, then the sink top must be drilled.
Choose a convenient location as described in
Sec. III, C.1, page 6.
1. Mark the location of the center of the faucet
base.
2a. Drilling a stainless steel sink:
•Center punch the hole to provide a starting
point for the drill.
•Start with a smaller drill as a pilot, and then
drill a ½" diameter hole to accept the bolt
of a 1¼" Greenlee Hole Punch (1¼" chassis
punch).
•Clean away any chips.
•Install the punch and tighten the nut to cut
the hole.
•Deburr any sharp edges.
2b. Drilling a porcelain sink:
It is best to use a special 1¼" diameter cutter
designed for porcelain. A carbide tipped
masonry bit is a second choice.
•Place a piece of tape over the area to be
drilled to help prevent chipping.
•Drill a pilot hole for the porcelain cutter.
Use the pilot drill supplied with the kit or a
carbide tipped drill.
•When drilling the 1¼" hole, drill slowly and
carefully; the porcelain chips easily.
•After drilling, clean the area well. Iron filings,
if left in place, can cause rust stains.
2c. Drilling a counter top:
NOTE: The counter top must be less than 1¼"
thick. Treat ceramic tile as porcelain until the
tile is penetrated, then use the carbide tipped
metal cutter.
Formica counter tops may be drilled with a
good 1¼" wood bit; drilling a 3/32" pilot hole
will help keep the bit going straight.

3. Assemble and attach the Faucet (refer to
Fig. 2 above).
•Assemble the Body and Spout by removing
the plastic shipping plug from the Body and
then firmly pressing in the Spout.
•In the following order, place the Face Plate
(Escutcheon) on the 7/16" stud.
•From the top of the counter place the stud
through the mounting hole.
•From the bottom of the counter top, in the
following order, assemble the Slotted Washer,
the Plastic Spacer (with open end upwards),
the 7/16" Washer and the 7/16" Hex Nut.
•To the end of the 7/16" stud screw on the 3/8"
Polytube Quick Connect Fitting. Once snug
by hand take a pair of pliers and tighten the
fitting an additional half turn. Don’t over
tighten.
•Rotate the Spout and Body into position.
Align the Slotted Washer and the Spacer to
allow access to the Hose Barbs, and tighten
the Hex Nut while holding the faucet in
alignment with a padded Crescent wrench.
Do not over tighten.
B. Feed Water Saddle Valve Installation
Decide on location. Do NOT connect to a hot
water feed line. If you are not sure of the supply,
run the hot water and feel the supply piping.
Water over 100°F may cause permanent damage to
the R.O. Membrane. (Refer to Fig. 3 below.)
1. Shut off the water supply and drain the line.
2a. To install on (soft) Copper Tubing supply
line:
•Turn the Handle of the Feed Water Saddle
Valve counter clockwise (outward) until the
lance does not protrude from the gasket. It
may have to be pushed in.
•Assemble the Feed Water Saddle Valve on
the tubing.
–for 3/8" OD tubing use the back plate side
with the small groove to prevent distortion of
the tubing.
–for larger tubing (up to 5/8" OD) use the large
groove of the back plate.
•Assemble and tighten the brass screw.
•To pierce the tubing, turn the Valve Handle
fully clockwise (inward). A small amount of
water may escape from the outlet until it is
fully pierced.
•When you feel the Valve Handle firmly
seated in the clockwise direction, the copper
tube is pierced and the valve is closed.
2b. To install on (hard) Steel or Brass Tubing
supply line.
•The supply line should now be drained. Use a
battery powered or properly grounded drill to
avoid shock hazard.

2. Use a battery powered or properly grounded
drill. Using the Clamp port as a drill guide,
drill a 7/32" hole through the wall of the drain
pipe. Do NOT penetrate the opposite side of
the pipe.
3. Locate the 3/8" Black Drain Tubing which is
shipped loose in the box.
NOTE: When cutting the polytubing make
clean, square cuts, failing to do so could result
in poor connections and possible leaks.
CAUTION: The lowest point of the line
should be the point of connection to the Drain
Clamp. There should be no sag in the line as
this may cause excessive noise as the reject
water is flowing to drain.
Firmly press one end of the tubing over the
3/8" drain outlet hose barb on the Dispensing
Faucet. Allow the tubing to relax, then press
firmly again to insure proper seating. No
connectors are required when attaching hose
to Hose Barbs. Route the tubing to the Drain
Clamp and trim to length.
•Refer to Fig. 4, below. Insert the tubing into
the Drain Clamp. Make sure the tubing is
pressed all the way in to create a pressure
tight connection.
NOTE: If you want to pull the tubing out for

•Drill a 3/16" hole in the supply line; (do not
drill through the opposite wall).
•Turn the handle to expose the lance no more
than 3/16" beyond the rubber gasket.
•Place the body of the valve over the hole so
that the lance fits into the hole.
•Assemble and tighten the brass screw.
•Turn the Valve Handle clockwise (inward)
until firmly seated. The valve is closed.
3. With the Feed Water Saddle Valve closed,
open the sink faucet and the water supply and
allow the water to run for a few minutes to
flush any debris caused by the installation.
•Close the faucet and check the Feed Water
Saddle Valve for leaks.
C. Drain Clamp Installation
Choose the drain outlet location per Sec. III, C.5,
page 7.
The following are instructions for discharging into
the sink drain pipe. (Refer to Fig. 1, page 3.)
1. Position the Drain Clamp on the sink drain
pipe above the drain trap. Allow room for
drilling. Tighten securely.

10
some reason, push the ring around the tubing
in and pull the tubing out.
D. R.O. Manifold Assembly Installation
Locate the site per Sec. III, C.3, page 7. Various
installation sites will require different types of
mounting fasteners; be sure the fastener selected
will provide a firm, solid mounting. A support
panel may be necessary on thin cabinet walls or
to span between wall studs on particleboard or
drywall.
Do not drill through exterior cabinet walls or
leave sharp wood screw points exposed in readily
accessible cabinet interiors.
The close proximity of a dishwasher or a trash
compactor may require special fabrication of a
mounting plate.
1. The mounting bracket will accept either
#10 or #12 (5mm) mounting screws spaced
on 6" (15 cm) centers. Allow at least 4" (10
cm) of clearance beneath the filter housings
to accommodate filter changes. Mark the
two locations (the bracket can be used as a
template). Install the screws and tighten them
until the heads are about 5/8" from the wall.
2. Locate the ¼" Red Feed Water Tubing.
Remove the red plug from the fitting labelled
“In”on the manifold and insert the tubing.
Reference the special supplement sheet in
the carton for proper connection of all tubing
and removal of plugs. Run the tubing along its
course to the Feed Water Saddle Valve, trim to
length. (Refer to Fig. 1, page 3.)
Refer to Fig. 3, page 8. To the end of the red
polytube install the Compression Nut, the
Plastic Ferrule, and the Insert. Connect to the
Feed Water Saddle Valve.
3. Locate the ¼" Black Drain Tubing. Remove
the black plug from the fitting labelled “Drain”
on the manifold and insert the tubing. The
end of the Black Drain Tubing that should
be inserted into the “Drain”port will have a
yellow drain restrictor in it. Run the tubing
along its course to the ¼" Hose Barb on the
Dispensing Faucet, trim to length and connect
by firmly pressing over the barb. Allow the
tubing to relax, then press firmly again to
insure proper seating.
4. Locate the ¼" yellow tubing with the tee
attached to one end. Remove the yellow plug
from the fitting labelled "Out" on the manifold
and insert the tubing.
5. Locate the 3/8" Blue Product Water Tubing.
Firmly press one end into the tee and the other
end into the faucet connector. (Refer to Fig.
1, page 3.) The fittings will grab the tubing
and seal it in place. Make sure the tubing is
pressed all the way in to create a pressure tight
connection.
NOTE: If you want to pull the tubing out for
some reason, push the ring around the tubing
in and pull the tubing out.
6. Hang the Manifold Assembly on the
mounting screws and tighten. DO NOT
OVERTIGHTEN.
7. Remove the wrapping from the
In–Line Activated Carbon Post Filter. Slice
the 3/8" Blue Polytube where it would be
convenient to install and change the In–Line
Filter. Make a clean straight cut to insure
proper connections. The “Out”port on the
In–Line Filter should be toward the faucet.
Firmly press in the tubing. The fittings will
grab the tubing and seal it in place. Make sure
the tubing is pressed all the way in to create a
pressure tight connection.
E. Position the Drinking Water Holding Tank and
Make the Final Hose Connections.
1. Check the tank precharge pressure. Make sure
it is between 5 to 7 psig. If not, use a bicycle
hand pump or other pump to bring the pressure
up to the 5 to 7 psig range.
2. Pull the cap/plug off the top of the tank where
the Tank Shut–Off should go. (Refer to Fig. 1,
page 3.)
3. Wrap the white teflon tape, included in the
box, three times around the ¼" male outlet
thread. Wrap in the direction of the threads
(clockwise when looking down on the Holding
Tank). The tape will act as a thread sealant.
Screw on the Holding Tank Shut–Off Valve.
4. Locate the 3/8" Yellow Tubing. Firmly press one
end into the Holding Tank Shut–Off Valve
and the other end into the tee. (Refer to Fig.
1, page 3.) The fittings will grab the tubing
and seal it in place. Make sure the tubing is
