GENERAL DESCRIPTION OF SYSTEM
This under counter reverse osmosis water treatment system includes three major components identified as the
Reverse Osmosis Head Assembly, the Storage Tank and the Long Reach Faucet.
The REVERSE OSMOSIS HEAD ASSEMBLY is comprised of three to five separate filtering stages, determined
by your water treatment requirements. Each stage is designed to remove a particular type of impurity and are
identified as:
A) The sediment filter which reduces suspended matter from tap water by passing it through a cartridge
filter preparing the water for the reverse osmosis membrane.
B) Precarbon which contains activated carbon to reduce chlorine. In systems with TFC membrane,
chlorine will damage membrane.
C) The Reverse Osmosis Membrane which is a semi-permeable membrane and is the heart of the
system. Here, the remaining suspended solids and most of the dissolved impurities are separated
from the water molecules and flushed down the drain.
D) The postfilter which contains activated carbon, removes any residual taste and odor from the product
water.
The STORAGE TANK is designed to store up to 2 ½gallons of product water. The storage tank is shipped
pressurized (5-7 psi when empty) to force the water up to the long reach faucet when it is opened.
The LONG REACH FAUCET provides a convenient means to draw water from the R.O. storage tank. It is a
compact, chrome plated fixture with a two position black handle that allows either continuous flow when lifted
up or an intermittent flow when the handle is pushed down. NOTE: some models may have a faucet with a
chrome rotating handle to regulate the flow.
This system can be used to supply water to an ice maker or additional remote faucets. If such an arrangement is
desired, contact the distributor for further information.

INSTALLATION PROCEDURE
This reverse osmosis unit is designed to operate at water pressure in the range from 40 psi to 70 psi.
At lower pressures the reverse osmosis membrane will produce lower quantity and quality drinking water and
severe damage to the system may result. Low pressure boost pumps are available from your dealer and will
quietly supply the required pressure to the reverse osmosis unit for optimum performance and life.
If local water pressure exceeds 70 psi, a pressure regulator should be installed, reducing the water pressure into
the system. Operating the system at pressure exceeding 70 psi voids the warranty on the system.
PREPARATION FOR INSTALLATION
This reverse osmosis unit is compactly designed to fit under most kitchen sinks. Before proceeding with the
installation, the optimum positioning of components must be determined. The following guidelines should be
considered in making this determination.
A) The REVERSE OSMOSIS HEAD ASSEMBLY will free stand alone or may be mounted against a vertical
surface in a position to allow access for service and filter cartridge changing. The reverse osmosis head
assembly should be relatively close to the sink drain and the long reach faucet location to maximize flow
rate.
B) The STORAGE TANK should be located where it can be removed, if necessary, without taking away
needed storage space. The storage tank can be placed in any position, including on its side, without
affecting the performance of the system. The storage tank can also be located up to fifteen feet (15’) away
from the reverse osmosis head assembly with nominal pressure loss.
C) The LONG REACH FAUCET location should be convenient and positioned to assure a free flow pattern
into the sink. It must also be in a location that allows ready accessible from the sink with clear access for
the mounting hardware. If the faucet stud will not be of sufficient length, an extension is available.

INSTALLATION OF WATER SUPPLY CONNECTOR
WARNING: CONNECT TO COLD WATER ONLY.
CONNECTING THE REVERSE OSMOSIS HEAD ASSEMBLY TO
HOT WATER WILL DAMAGE THE MODULE AND VOID THE
WARRANTY.
1. Turn off the cold water supply to the sink faucet by locating the round or oblong handle on the right side
of the sink cabinet and turning clockwise until water supply is off. If you are not sure which is the cold
water line, turn on the hot water for a few minutes and feel the pipes.
NOTE: Some mixing type faucets may require that the hot water by shut off as well. If the cold water shut-off
valve fails to turn off the water, the house water supply can be turned off at the main.
2. The water supply adaptor can be installed at the faucet connection of the cold water line or at the shut-
off valve connection. Typical installations below:
3. Disconnect the threaded nut at the connection and thread the water supply adaptor, with the flat washer
and cone washer in place, onto the connection and tighten. Connect the tubing to the water supply to the
sink faucet and check for leaks.

INSTALLATION OF SADDLE VALVE ASSEMBLY
TO INSTALL THE “SADDLE TAPPING VALVE” ON COPPER TUBE
CAUTION: Do not turn handle before or while installing the saddle valve. Also confirm the piercing lance
does not protrude beyond the rubber gasket.
1. Locate the cold water shut off valve on the cold water line under your sink.
2. Assemble the saddle valve on copper tube.
A-For 3/8” O.D. tubing use “Pat. Pend.” Bracket with side projections to prevent distortion of the
tubing.
B-Use “V” side of bracket for all larger sizes of tubing.
3. Tighten screws evenly keeping the brackets parallel to one another.
4. Make the water connection to the outlet of the saddle valve. Should you fail to do this before piercing
the tube a small amount of water will escape from outlet until you are fully pierced.
5. Turn the handle clockwise until you feel it is firmly seated.
NOTE: You have now pierced the copper tube and the valve is closed.
6. Turn the handle counterclockwise to open the valve.
7. Tun on cold water shut off valve to check installation for leaks. Allow water to run from sink faucet for
a few minutes to clear any debris in the line caused by installation.

TO INSTALL THE SADDLE VALVE ON STEEL OR BRASS PIPE
1. Shut off water supply and drain the line.
2. Drill a 3/16” hole in pipe. Use a hand drill to avoid shock hazard.
3. Turn handle to expose lance beyond the rubber gasket no more than 3/16”
4. Place body of valve over hole so that lance fits into the hole.
5. Tighten bottom clamp evenly-Brackets should be parallel.
6. Turn handle clockwise to close valve.
7. Open the water supply and allow water to run from sink for a few minutes to clean any debris in the line
caused by installation.
8. Turn handle counter clockwise to open valve.
INSTALLATION OF DRAIN SADDLE
1. The drain saddle should be installed above the trap on the vertical or horizontal tailpipe.
2. Drill a ¼” hole into the drain pipe observing the above positioning.
NOTE: If positioning on the horizontal pipe (preferred location) the hole for the drain saddle should be drilled
at a slight incline to avoid noise.
To avoid noise on the vertical pipe, position the drain saddle low above the trap.
3. Mount drain saddle, aligning holes.
4. Carefully tighten the bracket screws evenly keeping the brackets parallel.

INSTALLATION OF LONG REACH FAUCET
NOTE: This system includes a standard sink top long reach faucet without an air-gap. In localities where
plumbing codes require installation of an air-gap, contact the distributor to obtain an air-gap faucet.
It is recommended that the system representative be consulted for proper tools, techniques and other assistance
in performing the following procedure.
The units manufacturer accepts no responsibility for sink top damage resulting from this installation.
SAFETY GLASSES should be worn to protect your eyes while drilling the faucet hole.
1. For best results a ½” carbide tipped masonry drill bit should be used to drill the sink hole for the long
reach faucet.
2. Carefully select the faucet location confirming it will have a neat water fall pattern and that the faucet
stud will be accessible from below once the hole is completed.
NOTE: If the faucet stud will not be long enough, an extension is available from your distributor.
3. PORCELAIN SINKS: Before starting the drill motor, apply firm downward pressure on the drill bit
until a crunching occurs. This will help keep the drill bit from walking when starting the hole.
4. STAINLESS STEEL SINKS: Before using the ½” carbide drill bit, an indent should be made with a
center punch to keep the drill bit from walking. A small pilot hole will cause excessive wear on the bit
and progress will be slow.
5. Keep steady firm downward pressure while drilling the hole. Too little during the start of the hole will
cause excessive wear on the bit and progress will be slow.
6. Once the hole is completed, immediately clean the area of metal chips and roughness around the hole.
Metal chips will stain porcelain sinks.

Assemble the faucet as shown:
The faucet shown has two operating positions. The black handle can be pushed downward for intermittent
water flow or lifted up into a locking position for continuous flow.
MOUNTING THE REVERSE OSMOSIS HEAD ASSEMBLY
1. Using the bracket as a template, mark the screw location at the desired position.
2. Screw two hex screws into the sidewall leaving enough protruding to allow the bracket to slide over
them.

CONNECTING THE FITTINGS
The following types of fitting for tubing connections may be found upon the reverse osmosis drinking water
system.
BRASS COMPRESSION - To complete the tubing connections using brass compression fittings:
1. Slide the compression nut onto the tubing
2. Slip a white plastic onto the tubing with the small beveled end towards the end of the tubing. DO NOT
use brass sleeves with plastic tubing.
3. Insert a brass insert into the tubing end
4. Bottom the end of the tubing completely into the brass fitting and tighten with a wrench.

PLASTIC COMPRESSION FITTINGS - To complete the tubing connections using plastic compression
fittings:
1. Cut the tubing squarely without burrs.
2. Slip the compression nut over the tubing.
3. Fully insert the tubing into the fitting body until the tubing bottoms. Holding the tubing in place, begin
to tighten the compression nut onto the fitting.
4. Hand tighten the compression nut and then tighten with a wrench 1 ½- 2 turns.
5. All nuts must be retightened when the system reaches projected operating temperature.

QUICK CONNECT FITTINGS - To complete the tubing connections using quick connect fittings:
1. Confirm the tubing ends are cut squarely not at an angle and without burrs.
2. Firmly insert the end of the tubing into the quick connect fitting until the tubing bottoms. The tubing
will insert into the fitting approximately 5/8”.
3. To remove the tubing from the quick connect fitting, press firmly and evenly on the protruding collet
with your fingers or 3/8” wrench. The gripping mechanism will release and the tubing may be
withdrawn.
NOTE: If the quick connect fitting slightly weeps water after connecting, Remove the tubing squarely and
insert again.
TUBING CONNECTIONS below designate tubing color and the label on the reverse osmosis head assembly
associated with the fitting connection point.
A. Connect the BLACK tubing to the DRAIN
B. Connect BLUE tubing to long reach FAUCET stud.
C. Connect WHITE tubing to shut off valve fitting on the storage TANK.
D. Connect ORANGE tubing to the cold FEED water supply connector.

START-UP PROCEDURE
1. Check to see all connections are made.
2. Check that all of the pre-filter and postfilter housings are secure.
3. Slowly turn on the water by turning the needle valve counterclockwise.
4. The valve handle on top of the tank should be in the open position, parallel to the valve body.
5. The black handle of the long reach faucet should be perpendicular to the spigot (closed).
6. Check for leaks.
7. The reverse osmosis drinking water system processes drinking water at a slow rate and may require 6 to
8 hours before water is readily available from the long reach faucet on a continual basis. It will take
longer if also connected to a refrigerator ice maker.
CAUTION FOR YOUR SAFETY BEFORE USING THE WATER FROM YOUR UNIT READ THE
FOLLOWING INSTRUCTIONS
DO NOT use the first tank of water. Drain the first full tank of water to the drain in order to purge entrapped
air from the system and rinse down the new carbon filter. This process prepares the system to produce quality
water.
NOTE: The first few tanks of water may have very small air bubbles in the processed water. It will clear itself
with normal use or you may drain the tank additional times.
N O T I C E: THE PERFORMANCE OF YOUR WATER SYSTEM IS AFFECTED BY WATER
TEMPERATURE AND WATER PRESSURE.
Your water system has been tested to verify that it will reject at least 90% of the total dissolved solids in the tap
water and produce the required gallons of quality water in a 24 hour period. These tests were performed at
standard conditions in which the tap water was at approximately 68 degrees Fahrenheit (20 degrees C) with a
water pressure of 60 psi. Actual performance in your home will vary if the water temperature and pressure are
different from these standards.
At temperatures lower than 68 degrees Fahrenheit the amount of water produced will decrease by about 0.1
gallons for each degree of temperature less than 68 degrees Fahrenheit.
At pressures lower than 60 psi, the amount of water produced will decrease by about 0.1 gallons for each 1 psi
lower than 60 psi.
