Introduction
Please read this entire service guide prior to
beginning installation.
The Valueline reverse osmosis drinking water system has been designed for quick and simple installation and
maintenance . By carefully reading this instruction manual and following the operational guidelines you will insure a
successful installation and reliable operation. Routine maintenance is essential to the longevity and performance of
the system. Filters should be changed every six to twelve months depending on the quality of the feed water supply.

Note: Do not tamper with the air valve on the storage
tank. It has been preset and screwed on with blue cap
by the manufacturers.
(1) Wrap the threads on the top of the water storage tank 3
times with plumbers (teon) tape only. Make sure it is tight,
but not over tight.
(2) Connect the tank ball valve assembly to the top of the
water storage tank.
(3) Connect the tube from the RO module to the water storage
tank.

Starting Your Installation
Preparation
Check the following list of components to ensure that all
parts are packed with your system.
1 - Storage Tank
1 - RO System
1 - Faucet
1 - Installation Kit
Determine the location for the installation of the RO
system. Avoid locations where the system might come
in contact with hot water pipes or other hazards.
Determine the location for the faucet. Check to see that
drilling the faucet hole will not damage pipes or wires
running underneath the sink.
Fittings and Tubing
Compression ttings are used throughout the system.
To insure a optimal seal, tubing should be cut with the end
square. An angled cut or distortion of the tubing will not
provide an efcient seal and may cause leaks.
To Install a tube, push in the collet until it seats rmly. To
remove a tube, push in the collet and pull out the tube.
Determine the location for the storage tank. A maximum
distance from tank to faucet of 15 feet is possible. The
system will produce a faster ow at the faucet with the
shortest tubing run from tank to faucet.

Source & Drain Water Saddle Valve
Shut Off the Water
Locate the water shut-off valve for the cold water feed
line you choose to use for the supply. Accidentally
hooking up the system to the hot supply line will
permanently damage the membrane (See Conditions
for operation). To assure you are using the cold
water line, turn on both the hot and cold faucet. After
the water is warm to the touch, feel the pipes under
the sink. It will be easy to identify the hot and cold
pipes.
Close the cold water valve. Turn on the cold water
faucet only to assure that the line is completely shut
off and the line is drained.. If no shut off valve is
located under the sink, turn off the main supply at
the entry to the house.
Installing Supply Feed
(A) Flex Line: Loosen nut and separate cold water
riser tube from faucet shank. Gently bend riser tube
so that slip joint ts onto faucet shank. Replace the
existing cone washer with new washer provided in
installation kit onto cold water riser tube. Reinstall
riser tube onto slip joint adapter and tighten.
(B) Solid Copper Riser Tube: Same procedure as
ex tubing except you must cut a piece of the riser
tube about 3/4” to 1” so the slip joint adapter can t
between faucet and riser tube (Teon tape must be
used on slip joint adapter to prevent leaks).
Installing the Drain Clamp
Select a location for the drain hole based on the design of the
plumbing. Position the drain outlet saddle on the drain pipe.
Allow adequate space for drilling. Tighten the bolts evenly on
both sides. Avoid overtightening.
Using the opening in the drain outlet saddle as a guide, drill a
1/4” hole in the drain pipe. Clean debris from the saddle and
threads.
NOTE: Some states require the use of an air gap faucet. Check
your local plumbing code to assure compliance. Locate the
drain connection away from the garbage disposal to prevent
potential contamination and system fouling.

Installation - Product Water Faucet
Drilling the Faucet Hole
The product water faucet may be installed on any at
surface at least 2” in diameter. Check the underside of
the location for interference.
Porcelain/Enamel Sinks
A 3/8” variable speed drill is recommended for this
procedure.
A spring loaded Relton style drill set is strongly
recommended to prevent chipping.
The plastic sleeve supplied on the pilot drill is to be
positioned on the drill bit against the drill chuck. This
prevents the chuck from contacting the porcelain after
the pilot hole has been completed.
Avoid high motor RPM during the initial cutting of the
porcelain as this can cause chipping.
Using a carbide tipped drill bit, drill a pilot hole completely
through the porcelain and the material underneath.
Place the spring loaded porcelain saw into the drill chuck.
Make sure the pilot guide is inserted tightly. Insert the
pilot guide into the pilot hole. Push down gently on the
drill motor to apply light pressure to the porcelain surface.
Start the drill motor turning as slowly as possible.
After the initial cut has started, motor speed may be
gradually increased. The cut may require three to
four minutes to complete. Going faster could result in
excessive chipping. This saw is used to cut the porcelain
only. Be sure a complete ring has been cut through the
porcelain to the metal underneath.
Place the nish hole saw into the drill chuck. Make sure
the pilot guide is inserted tightly. Insert the pilot guide
into the pilot hole. Begin cut using a slow speed and light
pressure until the metal has been penetrated.
Stainless Steel Sink
Make a small indent to mark the desired drilling location
using a center punch. Drill a pilot hole with a 1/8” metal
drill bit. Enlarge the hole using a 3/8” metal drill bit.
Tile Counter Top
Follow the procedures outlined in the Porcelain/Enamel
Sinks section.
Faucet Installation
Once the hole has been drilled in the sink, the faucet may
be located in the hole. Be sure the faucet body, faucet
base, and the rubber faucet base washer are in place
above the sink.
Install the star lock washer and nut, then tighten rmly
while aligned faucet in the desired direction.
Additional Point of Use Connection
NOTE: Icemakers typically use 1/4” tubing as the water
feed line. Use a reducing union tting to make this
connection
To connect an additional point of use (icemaker, extra
faucet, etc.), place a ‘T’ connector in the 1/4” line between
the faucet and the RO system.
Drilling with the recommended Relton cutter

Activation, Troubleshooting, Maintenance
Activating the System For the First Time
Make sure all water supply/drain lines are secure and
free from leakage.
Slowly turn the saddle valve counterclockwise until fully
open. Check stem seal for leakage. If necessary tighten
stem nut lightly.
Turn storage tank valve one quarter turn counterclockwise
to open the valve (the handle should be in line with the
tubing as it enters the connection).
Open the product water faucet and let the water ow until
all the air has been expelled from the system. This will
take about an hour.
Close the product water faucet. In 30 minutes, check the
connections for leaks and correct if necessary.
Maintenance- Imperative to follow the sequence as outlined
Note that lters are labeled for easy servicing.
1) Open the RO faucet and let the tank drain completely. Leave the faucet open until the
lter change is complete.
2) Remove the pre-sediment cartridge.
3) Remove the pre-carbon cartridge.
4) Remove the membrane cartridge - The membrane may be reused indenitely as long
as the TDS level and other troubleshooting guidelines are met.
4) Remove the post-carbon cartridge.
5) Install the new lters.
6) Turn on the system and inspect for leaks.
7) Drain the rst tank of water after changing the lters before drinking. When the membrane
is changed, drain the rst two tanks of water before drinking.
Do Not Use the First Two Reservoirs of Water
Allow the reservoir to ll for 4-6 hours. Dispense this water to drain. This process removes the factory installed sanitizing
solution from the entire system and sends it to the drain. Repeat this process one more time. Allow the tank to ll for
4-6 hours and dispense this water to the drain.
