TYPICAL T.F.C.–400 UNDER SINK INSTALLATION DIAGRAM
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 Prelter
has been designed to reduce 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.
ACTIVATED CARBON–The Activated Carbon
Prelter 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 Prelter has been
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 classied 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.

SECTION II. SPECIFICATIONS
TABLE A – QUALIFIED SYSTEM PERFORMANCE
Because the performance of an R.O. Membrane is highly dependent upon pressure, temperature and TDS, the
following should be used for comparison purposes only.
U.S. Metric
Membrane Production140-60 gpd 151–227 lpd
Membrane TDS Reduction193% minimum 93% minimum
Drain (reject water) Flow 3–5 x product ow 3–5 x product ow
Empty Storage Tank Precharge 5–7 psig air 35–48 kPa air
1Industry 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 600 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.

SECTION III. 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 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.
•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.
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 the 1/8” Screws & Toggle Wings
into the Faucet Base. Adjust the Wings
approximately 1” plus the thickness of the
mounting surface away from the bottom of
the Faucet Base.

7
4. Place the Base Assembly through the
mounting hole on the sink or counter top.
Drop the handle of the Wrench through the
Faucet Base opening. This will separate and
orient the Toggle Wings. Position the Faucet
Base so that the arrows are pointing in the
direction that the faucet handle will face.
Tighten the 1/8” Screws with a Phillips
screwdriver. When the Toggle Wings make
contact with the mounting surface, adjust the
Faucet Base to the exact desired position.
Tighten the 1/8” Screws an additional 2 –3
turns while holding the Faucet Base in place.

Connect Fitting. Push the Black 3/8” Polytube
onto the large Hose Barb. Push the Black ¼”
Polytube onto the small Hose Barb.
6. Determine which direction the handle
should face (right or left). As shown, it can
be mounted in two directions. With the
handle facing the chosen direction, slide
the fastened Polytubes through the Faucet
Base and slide the Faucet Assembly into the
Faucet Base, lining up the tabs on the Faucet
with the slots on the Base. The Faucet
Assembly may have to rotate slightly to get
the tabs into the slots. When aligned, apply
rm downward pressure 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.)
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.
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.

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.

9
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 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.
NOTE: 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.
Route the tubing to the Drain Clamp and
trim to length. Insert the tubing into the Drain
Clamp. Make sure the tubing is pressed all
the way in.
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 labeled
“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 labeled “Drain” on the
manifold. The end of the Black Drain Tubing
that should be inserted into the “Drain” port
will have a drain restrictor in it.
4. Locate the ¼" yellow tubing with the tee
attached to one end. Remove the yellow plug
from the tting labeled "Out" on the manifold
and insert the tubing.
5. Locate the 3/8" Blue Product Water Tubing
connected to the faucet. Firmly press one
end into the tee. (Refer to Fig. 1.) The tting
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.

10
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 Teon 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
At time of start up and each time the lters are
changed the system should be sanitized (also
see Operation and Maintenance Sec. IV, B.1–4).
1. Sanitizing the system and installing the
Sediment Prelter. Use a drip pan to aid
clean–up.
NOTE: The system should be sanitized
BEFORE installing the Activated Carbon
Prelter and the RO Membrane.
•Use a good quality unscented 5¼% liquid
chlorine household bleach.
•Open the Dispensing Faucet and open the
Holding Tank Shut–Off Valve (the handle
should be parallel with the valve body).
•Remove the plug on the underside of the
manifold labeled “SEDIMENT”. Pour one
capful of bleach (this is approximately
2 tsp. or 10 ml) into one of the white
Housings. AVOID GETTING BLEACH
ON THREADS AND O-RINGS. Unwrap
Sediment Prelter and install prelter
(O-rings up toward manifold.) Insert a
Housing O–ring into the Housing groove,
(press rmly in place). Engage and rmly
tighten the Housing hand tight only.
•Remove the plugs labeled “ACTIVATED
CARBON” and “MEMBRANE” from the
underside of the manifold. To each of the
remaining white Housings, add one capful
of bleach. AVOID GETTING BLEACH ON
THREADS AND O-RINGS. Insert a Housing
O–ring, engage and rmly tighten the
Housings hand tight only.
•Slowly open the Feed Water Saddle Valve
(turning counter clockwise).
•As soon as the water begins to come out of
the Dispensing Faucet, close the Faucet.
•Let stand for 15 minutes.
NOTE: During this time, check the system
carefully for leaks.
•At the end of 15 minutes, CLOSE the
Feed Water Saddle Valve and open the
Dispensing Faucet.
•Allow the Holding Tank to completely drain.
Then remove the Activated Carbon Prelter
Housing (the middle one), empty, and install
the Activated Carbon Prelter. Firmly tighten
the Housing hand tight only.
2. Installing the R.O. Membrane:
•Remove the R.O. Membrane Housing, (the
closest of the three to In/Out ports), and
empty.
•Insert the Membrane up into the manifold.
(The O–rings should be up toward the
manifold.) Check the Housing O–ring for
proper position in its groove, engage and
rmly tighten the Housing hand tight only.
3. Rinsing the system:
•Slowly open the Feed Water Saddle Valve
fully counter clockwise.
•The Holding Tank Valve should be open.
•Check the Air Gap Window 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.

11
When the Faucet is rst opened, expect air
and carbon nes (very ne black powder)
from the In–Line Activated Carbon Post
Filter to be rinsed out. This is normal for the
rst tank of water or after the In-line lter is
changed.
SECTION IV. 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%.
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 rell 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 prelter and post
lters.
B. Changing Filters
THIS R.O. SYSTEM CONTAINS FILTERS
WHICH MUST BE REPLACED AT REGULAR
INTERVALS TO MAINTAIN PROPER
PERFORMANCE. USE ONLY FACTORY
APPROVED FILTERS.
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
lters (not the R.O. Membrane) is every
6 to 12 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. III, F.1–3 for the proper procedure.
Use a drip pan to catch any water that may spill
when the Filter Housings 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.
2. Loosen and remove the Sediment Prelter
and the Activated Carbon Prelter Housings.
Discard the lters.
3. Wash the inside of the Housings using a
mild detergent and a soft cloth. Do not use
abrasive cleaners or pads. Thoroughly
rinse all soap from the Housings before
reassembly.
4. To sanitize the system and replace the lters:
NOTE: The system should be sanitized
before installing the Activated Carbon
Prelter.
•Use a good quality unscented 5¼% liquid
chlorine household bleach.
•Add one capful of bleach (this is 2 tsp. or
10 ml) to the Sediment Prelter Housing
and install the Sediment Prelter. AVOID
GETTING BLEACH ON THREADS AND
O-RINGS. Check the Housing O–ring for
proper position in its groove, engage and
rmly tighten the Housing hand tight only.
•Add one capful of bleach to the Activated
Carbon Prelter Housing. AVOID GETTING
BLEACH ON THREADS AND O-RINGS.
nstall the Housing without the Activated
Carbon Prelter.

12
•The Dispensing Faucet should be open,
slowly open the Feed Water Saddle Valve.
•As soon as water begins to drip out of the
Dispensing Faucet, close the Faucet.
•Let the system stand for 15 minutes.
•At the end of 15 minutes, in the following
order, close the Feed Water Saddle Valve,
close the Holding Tank Valve and open the
Dispensing Faucet to release the pressure.
•Remove the Activated Carbon Prelter
Housing and empty. Remove the wrapping
and install the Activated Carbon Prelter.
Firmly tighten the Housing hand tight only.
•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 it to the Tee.
NOTE: Now is the convenient time to
change the In–Line Activated Carbon Post
Filter, see Sec. IV, 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.

R.O. DRINKING WATER SYSTEM
FIVE/ONE YEAR LIMITED WARRANTY
What Does This Warranty Cover?
This warranty covers any defects in materials and workmanship of the R.O. Drinking Water System when
installed and operated within recommended parameters, with the exceptions stated below.
How Long Does The Coverage Last?
The manufacturer will warrant its R.O. Drinking Water System (except for the reverse osmosis membrane), for
a period of ve years from the date of purchase. The reverse osmosis membrane is warranted for one year from
date of purchase. All implied warranties including merchantability and tness for a particular purpose are limited
to ve years from the date of purchase for the R.O. Drinking Water System, except for the reverse osmosis
membrane which is limited to one year from date of purchase. Some states do not allow limitations on how long
an implied warranty lasts, so the above limitations may not apply to you.
What Will The Manufacturer Do?
The manufacturer will repair or replace at its discretion any defective component. You must pay any labor
charges. You must also pay for shipping or travel charges to return the defective part(s).
What Does This Warranty Not Cover?
This warranty does not cover the disposable sediment and carbon lters whose service life depends on feed water
conditions. In addition, the membrane is only warranted if the required feed water conditions are met.
The above warranty will also not apply to any part of the R.O. Drinking Water System that is damaged because
of neglect, misuse, alterations, accident, misapplication, physical damage, or damage caused by re, acts of
God, freezing or hot waters or similar causes. Consequential and incidental damages are not recoverable under
this warranty. Some states do not allow the exclusion or limitation of incidental or consequential damages, so the
above limitation or exclusion may not apply to you.
We recommend that you use only the manufacturer's replacement parts since improper parts or incorrectly
performed maintenance or repair voids this warranty.
How Do You Get Service?
In order to be eligible for service under this warranty you must (a) contact your local dealer who supplied the
unit.
How Does State Law Apply?
This warranty gives you specic legal rights and you may also have other rights which vary from state to state.
