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 immunodeciencies.
The EPA has stated that they do not know the signicance 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 Certied 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 lter cartridges, including wearing protective gloves, to avoid direct contact with the
exhausted cartridges.
*For complete specications, refer to the Performance Data Sheet.

SECTION I. INTRODUCTION
Your new Reverse Osmosis (R.O.) Drinking Water
System uses a combination of ltration 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–The Sediment
Module has been designed to reduce the larger
particles such as silt, rust and scale. Its 5 micron
(equal to 0.0002 inch) nominal rating
give maximum life to the R.O. Membrane.
helps to
ACTIVATED CARBON–The Activated Carbon
Module 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. The activated
carbon in the Module is designed to reduce any
chlorine that may be present in the feed water.
This pretreatment is necessary for membrane
protection.
REVERSE OSMOSIS MEMBRANE–The R.O.
Membrane is the heart of the ltration 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 lm, and is classied 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.
IN–LINE ACTIVATED CARBON POST FILTER–
The In–Line Activated Carbon Post Filter is
located after the Holding Tank and has been
designed to reduce the tastes and odors that
may pass through the system. It adds a nal
polish to the water.
AUTOMATIC SHUTOFF VALVE–The ASO
Valve senses when the Holding 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 Water
Quality Monitor has been integrated into the
faucet base 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.
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 Holding 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.
IMPORTANT NOTICES:
This reverse osmosis system contains replaceable treatment components critical for effective performance. It is the
user's responsibility to, and the manufacturer strongly recommends that the user, periodically test the product water
to verify the system is performing satisfactorily. See the test kit(s) for sampling instructions.
This system is acceptable for treatment of inuent concentrations of no more than 27 mg/L nitrate and 3 mg/L nitrite
in combination measured as N and is certied for nitrate/nitrite reduction only for water supplies with a pressure of
280 kPa (40 psig) or greater.
This system conforms to NSF/ANSI Standard 58 for pentavalent arsenic reduction. See the Performance Data
Sheet and Arsenic Facts section for an explanation of reduction performance.
DO NOT USE WITH WATER THAT IS MICROBIOLOGICALLy UNSAFE OR OF UNkNOWN qUALITy, WITHOUT
ADEqUATE DISINFECTION BEFORE OR AFTER THE SySTEM.
Systems certied for cyst reduction may be used on disinfected water that may contain lterable cysts.

Industry standards measure R.O. Membranes performance with no backpressure on the product water, at 65 psig (448kPa) and 77°F
(25°C). Further conditions on the above are 250 ppm TDS. Production rate and TDS reduction gures are for a new Membrane that
has been rinsed for 24 hours. The production rate of a new Membrane can decrease by 10% per year or more, depending upon the
scaling and fouling tendencies of the Feed Water.

Measured at 50 psig, 77°±2° F, 750±40 mg/l TDS per section 6 of NSF/ANSI Standard 58. Recovery rating means the percentage
of the inuent water to the membrane portion of the system that is available to the user as reverse osmosis treated water when
the system is operated without a storage tank or when the storage tank is bypassed. Efciency rating means the percentage
of the inuent water to the system that is available to the user as reverse osmosis treated water under operating conditions that
approximate typical daily usage. This reverse osmosis system contains a replaceable component critical to the efciency of
the system. Replacement of the reverse osmosis component should be with one of identical specications, as dened by the
manufacturer, to assure the same efciency and contaminant reduction performance.

C. Site Selection for Major System Components
The R.O. System was designed to t under a
sink, however, because of space limitations
or other reasons, the system’s exible design
allows for other locations. When determining the
location remember that access to a cold water
tap line, the household drain, and ease of lter
replacement are important considerations.
All components and tubing should be located in
an area not exposed to freezing temperatures. If
winter temperatures are severe, the area should
be above the minimum temperature listed in
Table B, page 4 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
(lling 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 at 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 best the choices.
If a longer run of tubing is required, the
tubing 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 rm, 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 are 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 ood 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 overow.
7
Page 8
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 rst. Allow adequate tubing lengths
for any nal component position.
A. Faucet With Water Quality Monitor Installation
The faucet contains an anti–siphon air gap.
While the system is producing water, the drain
water ows 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.
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.
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.
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. The hole in the Monitor Housing should be
centered on the mounting hole. If cutting or drilling
a mounting hole, please note that the Monitor
Housing is elliptical and the hole which runs through
it is off center from front to back.
• 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 lings,
if left in place, can cause rust stains.
4. Feed the Monitor Cord through the 1 ¼”diameter
Monitor Housing opening so that it is positioned
above the Monitor Housing.
Assemble the 1/8” Screws & Toggle Wings into the
Monitor Housing. Adjust the Wings approximately
1” plus the thickness of the mounting surface away
from the bottom of the Monitor Housing.
8
Page 9
5. Place the Toggles of the Monitor Housing
Assembly through the mounting hole on the sink or
counter top.
Drop the handle of the Wrench through the Monitor
Housing opening. This will separate and orient the
Toggle Wings. Position the Monitor Housing so that
the display is facing forward.
Tighten the 1/8” Screws with a Phillips tip
screwdriver. When the Toggle Wings make contact
with the mounting surface, adjust the Monitor
Housing to the exact desired position. Tighten the
1/8” Screws an additional 2 –3 turns while holding
the Monitor Housing in place.
Drop the Monitor Cord back through the Monitor
Housings opening.

HOSE BARBS
7. Determine which direction the handle should
face (right or left). With the handle facing the
chosen direction, slide the fastened Polytubes
through the Monitor Housings 1 ¼” diameter
opening and slide the Faucet Assembly into the
Monitor Housing, lining up the tabs of the Faucet
with the slots on the Housing. The Faucet Assembly
may have to rotate slightly to get the tabs into the
slots. When aligned, apply firm downward force
to get the Faucet to fully seat. After the Faucet
Assembly is seated, lock it into place by rotating it
clockwise about 30 degrees.

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.)
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.
• 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 ts into the hole.
• Assemble and tighten the brass screw.
• Turn the Valve Handle clockwise (inward)
until rmly 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 ush any debris caused by the installation.
• Close the faucet and check the Feed Water
Saddle Valve for leaks.
3/8" DRAIN CLAMP ASSEMBLy
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 rmly
seated in the clockwise direction, the
copper tube is pierced and the valve is
closed.
Figure 4
C. Drain Clamp Installation
The following are instructions for discharging
into the sink drain pipe. (Refer to Fig. 1.)
1. Position the Drain Clamp on the sink drain
pipe above the drain trap. Allow room for
drilling. Tighten securely.
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 connected
to the Dispensing Faucet. Route to the tubing
to the Drain Clamp and trim to length.
10
Page 11
NOTE: When cutting the polytubing make
clean, square cuts, failing to do so could
result in poor connections and possible
leaks.
4. Locate the ¼" yellow tubing with the tee
attached to one end. Remove the yellow plug
from the tting labelled "Out" on the manifold
and insert the tubing.
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 owing to drain.
Insert the tubing into the Drain Clamp. Make
sure the tubing is pressed in all the way.
D. R.O. Manifold Assembly Installation
Various installation sites will require different
types of mounting fasteners; be sure the
fastener selected will provide a rm, 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 lter housings to
accommodate lter 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 tting 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.)
Refer to Fig. 3. 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 connected
to the Dispensing Faucet. Remove the black
plug from the tting 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 green drain
restrictor in it.
5. Locate the 3/8" Blue Product Water Tubing
attached to the Dispensing Faucet. Firmly
press one end into the tee. (Refer to Fig. 1.)
The ttings 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.
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 towards the faucet.
Firmly press in the tubing. The ttings will
grab the tubing and hold 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.)
3. Wrap Teon tape 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.) The ttings 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.

F. Start Up
1. Installing the modules and membrane and
sanitizing the holding tank.
•Open the Dispensing Faucet and close the
Holding Tank Shut–Off Valve (the handle
should be perpendicular to the valve body).
When the Faucet is rst opened, expect air
and carbon nes (very ne black powder)
from the In–Line and Activated Carbon Post
Filters to be rinsed out. This is normal for
the rst tank of water or after the Activated
Carbon Post Filters are changed.
•Remove the plug on the underside of the
manifold labelled “SEDIMENT”. Unwrap the
Sediment Module. Make certain the Module
O-ring is pressed rmly in the groove.
Engage and rmly tighten the module hand
tight only.
•Remove the plug labelled “ACTIVATED
CARBON” from the underside of the
manifold. Unwrap Activated Carbon
Module. Make certain Module O-ring is
rmly pressed in groove. Engage and rmly
tighten the module hand tight only.
•Remove the plug labelled "Membrane"
from the underside of the manifold. Trim
top of membrane bag, exposing the white
plastic seal. While holding onto bag, insert
membrane rmly into manifold. (The
O-rings should be up towards the manifold.)
Remove the bag from the membrane. Take
the remaining housing and insert housing
O-ring into its groove. Engage and rmly
tighten housing hand tight only.
•Close the Holding Tank Valve.
•Disconnect the yellow product water tubing
that runs from the Holding Tank to the
Tee (see Fig. 1). Put 50 drops of bleach
(this is ½ tsp. or 3 ml) into the tubing and
reconnect the Tee.
2. Rinsing the system:
•Slowly open the Feed Water Saddle Valve
fully counter clockwise.
•Open the Holding Tank Valve.
•Check the Air Gap on the Dispensing Faucet
to be sure that the drain water is owing.
The R.O. System is now making water.
•Do not open the Faucet for at least 8 hours.
•Do not use the rst three full tanks of water.
CAUTION: The R.O. Membrane is shipped
with a preservative in it. To ensure proper
rinsing of the R.O. Membrane it is important
to wait at least 8 hours before emptying
each tank.
SECTION V. OPERATION & MAINTENANCE
A. Normal Operation
1. It is normal for the Total Dissolved Solids
(TDS) of the water to be higher than normal
during the rst 5 gallons of operation; this is
due to the sanitizing solution and the new
Post Filters. After this water is rinsed to drain,
the removal rate should stabilize at a value of
greater than 75%. The Water Quality Monitor
was designed to measure water quality when
the R.O. system is making water. In order to
assure you are getting an accurate reading,
empty the holding tank, wait 15 minutes until
the system begins making water, and then
test the TDS with the monitor.
2. R.O. systems produce drinking water at
relatively slow rates; it can take up to 5 hours
or more to ll the Holding Tank. Normal
operation is to let the Holding Tank ll with
water and then draw water as is needed.
When the pressure in the Holding Tank falls
to a given pressure (as the water is being
used) the Automatic Shut–Off Valve (ASO
Valve) will start water production and the
system will rell the Holding Tank. When the
Holding Tank is full and no water is being
used, the ASO Valve will automatically shut
off the feed water to conserve water. The
more water that is used (up to the capacity
of the system) the better the R.O. system
will function. Other uses for the water are
owers, pets and rinsing glassware.
With each use it is recommended that you
run the faucet for at least 10 seconds prior to
using water. This is especially important if the
system has not been used daily. After periods
of non–use, such as a week of vacation, it is
better to empty the Holding Tank and allow
the system to produce fresh water for use. If
the system is not used for
3–4 weeks or longer, it is a good idea to
resanitize the system and to change the
prelter and post lters.

THIS R.O. SYSTEM CONTAINS MODULES
WHICH MUST BE REPLACED AT REGULAR
INTERVALS TO MAINTAIN PROPER
PERFORMANCE. USE ONLY FACTORY
APPROVED MODULES.
All individuals should take adequate precautions
when changing the lters, including wearing
protective gloves, to avoid direct contact with the
exhausted lters.
The recommended interval for changing the
modules (not the R.O. Membrane) is every
six (6) months. Typical T.F.C. Membrane life
expectancy is three years. Local conditions may
dictate more frequent changes.
NOTE: If the R.O. Membrane is to be replaced,
see Sec. IV, F.1–2, for the proper procedure.
Use a drip pan to catch any water that may spill
when the Filter Modules are removed. Refer to
Fig. 1 for component location.
1. Close the Feed Water Saddle Valve by
turning fully clockwise and open the
Dispensing Faucet. Allow the Holding Tank to
empty.
NOTE: Now is the convenient time to
change the In–Line Activated Carbon Post
Filter, see Sec. V, C.1–6.
•Slowly open the Feed Water Saddle Valve.
When water begins dripping out of the
Dispensing Faucet, in the following order,
close the Faucet and then open the Holding
Tank Valve.
•Do not open the Faucet for at least 8 hours.
•Discard the rst three full tanks of water
produced, they will contain chlorine.

2. Loosen and remove the Sediment Module
and the Activated Carbon Module. Discard
the modules.
3. To sanitize the system and replace the
modules:
•Unwrap the new Sediment Module.
•Using an eyedropper put 5 ml (this is
approximately 1 tsp.) of a good quality
unscented 5¼% liquid household chlorine
bleach down the center tube of the Module.
•Check the Module O-ring for proper position
in its groove, engage and tighten the
Module hand tight only.
•Unwrap the new Activated Carbon Module.
•Check the Module O-ring for proper position
in its groove, engage and tighten the
Module hand tight only.
•Close the Holding Tank Valve.
•Disconnect the yellow product water tubing
that runs from the Holding Tank to the Tee
(see Fig. 1, page 5). Put 50 drops of bleach
(this is ½ tsp. or 3 ml) into the tubing and
reconnect it to the Tee.

C. Changing the In–Line Activated Carbon Post
Filter
1. Close the Feed Water Saddle Valve by
turning fully clockwise.
2. Close the Holding Tank Valve and then
open the Dispensing Faucet to release the
pressure.
3. Remove the In–Line Activated Carbon Post
Filter. Disconnect the used Post Filter by
pressing in the connector’s collar and at the
same time pulling the tube out of the tting.
4. Firmly reconnect the polytubes to the new
Post Filter. (Refer to Fig. 5.) Make sure the
tubing is pressed all the way in to create a
pressure tight connection.
5. Slowly open the Feed Water Saddle Valve.
6. When water begins dripping out of the
Faucet, in the following order, close the
Faucet and open the Holding Tank Valve.
When the Faucet is rst opened, expect air
and carbon nes (very ne black powder),
from the new Post Filter to be rinsed out. This
is normal for the rst tank of water.
