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/Carbon Module 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
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.
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 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 influent concentrations of no more than 27 mg/l nitrate and 3 mg/l nitrite in
combination measured as N and is certified for nitrate/nitrite reduction only for water supplies with a pressure of 40 psig
(280 kPa) 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 certified for cyst reduction may be used on
disinfected water that may contain filterable cysts.

B. Tools Recommended for Installation
The following tools will cover most of the
installation sites encountered:
1. 3/8" variable speed electric drill.
2. Extension work light with outlet.
3. Safety glasses.
4. 1¼" porcelain hole cutter kit.
5. 1¼" Greenlee hole punch and 1/8" and
½" metal drill bits for pilot hole.

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 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
(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 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 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 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 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.

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 first. Allow adequate tubing lengths
for any final 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 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 7.
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, Water
Quality Monitor Faucet Base and tubing (refer
to Fig. 2A & 2B, page 9.)
•Assemble the Body and Spout by removing
the plastic shipping plug from the Body and
then firmly pressing in the Spout.
Locate the ¼" Black Drain Tubing which
is shipped loose in the box. Connect the
Black Drain Tubing to the ¼" Hose Barb on
the Dispensing Faucet by firmly pressing
over the barb. Allow the tubing to relax,
then press firmly again to insure proper
seating. The end of the Black Drain Tubing
that should be inserted into the "Drain" port
on the R.O. Manifold will have a blue drain
restrictor in it. DO NOT attach this end to
the Dispensing Faucet.
Locate the 3/8" Black Drain Tubing which is
shipped loose in the box. Firmly press one
end of the tubing over the 3/8" drain outlet
hose barb on the Dispensing Faucet. Allow
tubing to relax, then press firmly again to
insure proper seating. No connectors are
required when attaching tubing to Hose
Barbs.
Slide Water Quality Monitor Faucet Base
over ¼" Black Drain Tubing, 3/8" Black Drain
Tubing and 7/16" stud screw and seat with
Amber/Green LED's aligned under Air Gap
Window on Dispensing Faucet. (See Figure
2A, page 9.)
Assemble the Plastic Spacer (with open
end upwards and facing tubing), the 7/16"
Washer and the 7/16" Hex Nut onto the 7/16"
stud screw. Do Not tighten at this point.

•From the top of the counter place the stud,
tubing and Water Quality Monitor Connector
Cable through the mounting hole. See
Figure 2B, page 9.
•From the bottom of the counter top slide the
Slotted Washer between the counter top
and the Plastic Spacer with the open end
towards the tubing.
Tighten the 7/16" Hex Nut to hold everything
in place.
•Rotate the Spout and Body into position
making sure the faucet body is square and
properly aligned with the Water Quality
Monitor Faucet Base. 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.
•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.
Locate the 3/8" Blue Product Water Tubing.
Firmly press one end into the 3/8" Polytube
Quick Connect Fitting.
Note: If you want to pull the tubing out for
some reason, push the ring around the
tubing in and pull the tubing out.
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
page 11.)
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.
•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 5.)
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

11
to the Dispensing Faucet. Route to the tubing
to the Drain Clamp and trim to length.
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.
•Refer to Fig. 4, page 12. 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
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 5.)
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 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 blue drain
restrictor in it. If tubing needs to be trimmed

drain restrictor. Allow the tubing to relax, then
press drain restrictor 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
attached to the Dispensing Faucet. Firmly
press one end into the tee. (Refer to Fig.
1, page 5.) 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 towards the faucet.
Firmly press in the tubing. The fittings 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,
page 5.)
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 5.) 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.
F. Start Up
1. Installing the modules and membrane and
sanitizing the holding tank.
•Open the Dispensing Faucet by lifting the
black handle and close the Holding Tank
Shut–Off Valve (the handle should be
perpendicular to the valve body).
•Remove the plug on the underside of the
manifold labelled “SEDIMENT/CARBON”.
Unwrap the Sediment/Carbon Module.
Make certain the Module O-ring is pressed
firmly in the groove. Engage and firmly
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 into manifold. (The O-rings
should be up towards the manifold.) Take
the remaining housing and insert housing
O-ring into its groove. Engage and firmly
tighten housing 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
firmly pressed in groove. Engage and firmly
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 ½tsp. 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 Window on the
Dispensing Faucet to be sure that the drain
water is flowing. (Refer to Figure 2A, page
9.) The R.O. System is now making water.
•Do not open the Faucet for at least 8 hours.
•Do not use the first 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.
When the Faucet is first opened, expect air
and carbon fines (very fine black powder)
from the In–Line and Activated Carbon Post
Filters to be rinsed out. This is normal for
the first tank of water or after the Activated
Carbon Post Filters are changed.
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 first 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 fill the Holding Tank. Normal
operation is to let the Holding Tank fill 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 refill 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 flowers,
pets and rinsing glassware.
With each use it is recommended that you
run the tap for at least 10 seconds prior to
using water. Thi s is especially important
if the water tap 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

14
prefilter and post filters.
B. Changing Modules
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 filters, including wearing
protective gloves, to avoid direct contact with the
exhausted filters.
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, page 13, 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 page 3 for component location.
1. Close the Feed Water Saddle Valve by
turning fully clockwise and open the
Dispensing Faucet by lifting the handle. Allow
the Holding Tank to empty.
2. Loosen and remove the Sediment/Carbon
Module and the Activated Carbon Module.
Discard the modules.
3. To sanitize the system and replace the
modules:
•Unwrap the new Sediment/Carbon 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 ½tsp. or 3 ml) into the tubing and
reconnect it to the Tee.
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 first three full tanks of water
produced, they will contain chlorine.
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 fitting.
Unscrew the fittings on the In–Line, re–Te flon
tape them and install them on the new Post
Filter. Do not over tighten the fittings.
4. Firmly reconnect the polytubes to the new
Post Filter. (Refer to Fig. 5, page 15.)
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 first opened, expect air
and carbon fines (very fine black powder),
from the new Post Filter to be rinsed out. This
is normal for the first tank of water.
SECTION VI. TECHNICAL DATA
A. Water Quality
Water quality is normally measured with a
special meter that measures the water’s ability
to conduct electricity. The more dissolved solids
in the water, the higher the conductivity. The
results are usually reported in Parts per Million
(ppm) or Milligrams per Liter (mg/l) of Total
Dissolved Solids (TDS). (Although technically

15
they are not exactly equal, in most discussions
ppm = mg/l.)
R.O. Membranes are rated by the amount of
dissolved solids that are rejected. This rating is
a ratio of the TDS in the feed water to the TDS
in the product water and is reported as Percent
Rejection. If the feed water contained 100 ppm
of TDS and the product water contained 10 ppm
of TDS, 90 ppm have been rejected and the
reject ratio is 90%.
Percent Rejection =
Feed TDS–Product TDS x 100%
Feed TDS
EXAMPLE: Feed water is 500 ppm TDS and the
product water is 75 ppm TDS.
Percent Rejection = 500 –75 x 100%
500
Percent Rejection = 0.85 x 100% or 85%
B. Water Quantity
Water quantity is termed Flux or Product Water
Rate and is measured as the amount of water
produced in one day. It is reported as Gallons
per Day (gpd) or Liters per Day (lpd).
The flow of water to drain is the Reject Water
Rate and is measured as Gallons per Day (gpd)
or as Milliliters per Minute (ml/min).
Milliliters per minute x 0.38 = gallons per day
EXAMPLE: The drain flow will fill a graduated
cylinder to the 150 ml mark in one minute.
150 ml/min. x 0.38 = 57 gpd
If the container available measures ounces, use
the following conversion:
Ounces per minute x 11.2 = gallons per day
EXAMPLE: The product flow will fill 2½ounces
in two minutes.
2.5 oz. ÷2 min. = 1.25 oz./min.
1.25 oz./min. x 11.2 = 14 gpd
The Reject Ratio is the amount of water
produced compared to the amount of
water flowing to drain.
Reject Ratio = Reject Rate_
Product Rate
EXAMPLE: The product rate is 14 gpd and the
reject rate is 56 gpd.
Reject Ratio = 56 ÷14
Reject Ratio = 4 or 4–to–1
The Percent Recovery is another way to
measure the amount of water produced as
compared to the amount actually used.
% Recovery = Product Rate x 100%
Feed Rate
NOTE: The total flow or feed water rate into the
system is the sum of the product flow and the
drain flow.
EXAMPLE: The product water rate is 14 gpd and
the drain water rate is 56 gpd
Feed Rate = 14 gpd + 56 gpd = 70 gpd
% Recovery = 14 gpd x 100%
70 gpd
% Recovery = 0.20 x 100% or 20%
C. Net Pressure Differential
Most R.O. Membranes are rated at a
standardized condition of 77°F (25°C) and
65 psig (450kPa) discharging to atmospheric
pressure.
Product water quality and quantity greatly
depend upon the Net Pressure Differential
(Dp) across the R.O. Membrane. This pressure
differential is a summation of the feed water
pressure at the Membrane, which tries to push
the water through, the pressure in the Holding
Tank, which tries to push the water backwards
and the osmotic pressure, which also tries to
push the water backwards.
The Osmotic Pressure is in proportion to the

dissolved minerals in the water and can be
approximated by 1 psig for each 100 ppm of TDS
EXAMPLE: A feed water with 1500 ppm of TDS
would exert a backward pressure of about 15
psig on the membrane.
Net Pressure Differential =
Feed Water Pressure –Holding Tank Pressure –
Osmotic Pressure
The higher the net pressure differential,
the higher the quantity and quality of water
produced.
Some loss of production is normal when using a
pressurized Holding Tank.
