Thank you for your purchase of a state of the art Watts Reverse Osmosis (RO) water treatment system. Water quality
concerns are becoming more of a focus for the public. This Watts water treatment system has been designed and tested to
provide you with high quality water for years to come. The following is a brief overview of the system.
Your Reverse Osmosis System:
Osmosis is the process of water passing through a semi permeable membrane in order to balance the concentration of
contaminants on each side of the membrane. A semi permeable membrane is a barrier that will pass some substances like
clean water, but not other substances such as salts and minerals.
Reverse osmosis uses a semi permeable membrane; however, by applying pressure across the membrane, it concentrates
contaminants on one side of the membrane, producing clean water on the other. This is why RO systems produce both clean
drinking water and waste water that is ushed from the system.
Your system is a Four Stage RO which is based upon four separate treatment segments within one complete water ltration
system. These stages are as follows:
Stage 1 – Sediment lter, recommended change 6 months.
The rst stage of your RO system is a ve micron sediment lter that traps sediment and other particulate matter
like dirt, silt and rust which affect the taste and appearance of your water.
Stage 2 – Pre-Carbon lter, recommended change 6 months.
The second stage contains a carbon block lter. This helps ensure that chlorine and other materials that cause bad
taste and odor are greatly reduced.
Stage 3- Membrane, recommended change 1-2 years.
Stage three is the heart of the reverse osmosis system, the RO membrane. This semi-permeable membrane will
take out salts, minerals, metals, bacteria, viruses, cysts, and much more. Because the process of extracting this high
quality drinking water takes time, your RO water treatment system is equipped with a storage tank.
Stage 4- Post Carbon Filter, recommend change 12 months.
The post carbon lter is a granular activated carbon (GAC) cartridge using coconut shell carbon. This lter
provides nal polishing and assures good tasting drinking water.
System Maintenance
The Reverse Osmosis system contains a replaceable treatment component critical for effective reduction of total dissolved
solids. The product water should be tested periodically to verify that the system is performing satisfactorily. Just because
you can not taste it, does not mean that it is not there. Contaminants such as lead, chromium, and arsenic are undetectable
to the taste. Additionally, over time if you do not replace the lter elements, other bad tastes and odors will be apparent in
your drinking water. This is why it is important to change out your lter at the recommended intervals as indicated in this
system manual. Should you have any further questions please contact the dealer that you purchased the unit from.
With proper installation and maintenance, this system will provide you with high quality water for years to come.
All of Watts water enhancement products are rigorously tested.
NOTE: This manual is used for several variations of the same system. Your system may
vary slightly from the pictures or descriptions contained in this manual.
It is end users responsibility to ensure that this system is installed according to all
local codes and regulations.

Page 3
Installation must comply with State and local plumbing regulations. Do not use with water that is micro
biologically unsafe or of unknown quality without adequate disinfection before or after the system.
System is intended to be installed using the cold water supply only.

* System will operate with hardness over 10 grains but the membrane life may be shortened.
Addition of a water softener may lengthen the membrane life.
Copper Tube: Reverse Osmosis water should not be run through copper tube as the purity of the
water will leach copper causing an objectional taste in water and pin holes may form in the tube.
Water Pressure: The operating water pressure in your home should be tested over a 24 hour
period to attain the maximum pressure. If the incoming water pressure is above 100 psi then a
water pressure regulator is required. A booster pump is needed for incoming water pressure
under 40psi.

After drilling, remove all sharp edges and make sure the surroundings
of the sink are cooled before mounting the faucet.
Step 3
Step 4
Determine desired location for the RO faucet on your sink and place
a piece of masking tape over where the hole is to be drilled. Mark the
center of the hole on the tape.
Step 1
Using a variable speed drill set on the slowest speed, drill a 1/8“ pilot
hole through both porcelain and metal casing of sink at the marked
center of the desired location. Use lubricating oil or liquid soap to keep
the drill bit cool (If drill bit gets hot it may cause the porcelain to crack
or chip).
Using a 1 ¼” diamond tip hole saw, proceed to drill the large hole. Keep
drill speed on the slowest speed and use lubricating oil or liquid soap
to keep the hole saw cool during cutting.
Step 2
Counter Top / Porcelain & Stainless Steel Sink
Note: Most sinks are pre drilled with 1 ¼” diameter hole that you can use for your RO faucet.
(If you are already using it for a sprayer or soap dispenser, see step 1)
Porcelain sinks are extremely hard and can crack or chip easily.
Use extreme caution when drilling. Watts accepts no responsibility for
damage resulting from the installation of faucet. Diamond tip bit recommended.
Marble Counter-top
We recommend contacting a qualied contractor for drilling a hole in a marble counter-top.

How to use the Quick Connect Fittings
To make a connection, the tube is simply pushed into the tting. The unique locking system holds the tube rmly in place
without deforming it or restricting ow. Use the steps below in reference to any quick connect tube connections.
It is essential that the outside diameter be free of score
marks and that burrs and sharp edges be removed before
inserting into tting.
Fitting grips before it seals. Ensure tube is pushed into
the tube stop.
Push the tube into the tting, to the tube stop. The collet
(gripper) has stainless steel teeth which hold the tube
rmly in position while the O-ring provides a permanent
leak proof seal.
Pull on the tube to check that it is secure. It is a good practice
to test the system prior to leaving site and /or before use.
To disconnect, ensure the system is
depressurized before removing the tube. Push in the col-
lect squarely against face of tting. With the collet held
in this position, the tube can be removed. The tting can
then be reused.

Turn off the cold water supply to the faucet by turning the angle stop valve completely off.
Open cold water sink faucet to relieve pressure.
Step 5
Step 6 Choosing the conguration that ts your plumbing, attach the adapt-a-valve as illustrated in
the four photos above.
Adapt-a-Valve Installation
Do not use Teon tape with the Adapt-a-Valve.WARNING:
Caution: Water supply line to the system must be from the cold water supply line only.
Hot water will severely damage your system.
Make sure that the black collet is installed in to the 1/4” opening on the Adapt-a-valve.
Don’t forget to install the white compression washer with the 3/8” conguration.
Brass adapter (A) does not need to be tightened with a wrench, only nger tight.
TIPS:
Mount the Reverse Osmosis Faucet
Refer to installation instructions found on faucet box.
If installing an Air-Gap faucet, connect tubes to the faucet prior to mounting:

Drain Saddle Installation - Fits standard 1 ¼” – 1 ½” drain pipes
Step 8
Step 9
Step 10 The drain saddle must be installed at least 1 ½” above the nut of the
P-Trap elbow or cross bar from the garbage disposal to insure proper
drainage. Using the 1/4” drill bit, drill into the drain pipe at best available
location as specied above, for drain saddle installation. Take extreme
caution to only drill through one side of the drain pipe.
The small square black foam gasket with a circle cut out of the middle
must be applied to the inside of the drain saddle. Remove sticky tape
backing and stick to the drain saddle. (See Picture to Right)
Locate the correct drain saddle kit in the parts bag.
If you have a garbage disposal, do not install the drain saddle near it. Installation
of the drain saddle must be either above the garbage disposal, or if a second sink
drain is available, install it above the cross bar on the second drain. Installation
of the drain saddle near a garbage disposal may cause the drain line to plug.
Caution:
P-Trap
Elbow
Step 7 Determine if a 1/4” tube connection or 3/8” tube connection drain saddle
should be installed. For air-gap RO faucets (3 tubes) use larger 3/8” tube
connection drain saddle. For non air-gap RO faucets (1 tube) use 1/4”
tube connection drain saddle.
Assemble the drain saddle around the drain pipe and align drain saddle
tting opening with the hole drilled in the previous step - you may
use a small screwdriver to feed through the drain saddle into the drain
pipe to aid with the alignment. Using a Phillips screw driver tighten the
drain saddle bolts evenly and securely on both sides.
Step 11 1.5”
Caution: Do not over tighten the screws. It may crack the drain saddle.
Follow all local plumbing codes for your installation.

The 3/8” drain tube must be as SHORT and STRAIGHT as possible from the RO
faucet to the drain saddle, making a downward slope from faucet to drain saddle to
allow for proper drainage. This is a gravity fed line and if there is any bend or dip
in the tube, the rinse water will not ow into the drain properly. Water may back
up and come out the air gap hole in the back of the faucet.
Locate the 3/8” drain tube attached to the RO faucet.
Measure the 3/8” drain tube from the RO faucet to the drain
saddle mounted on the drain pipe and make a straight cut
to the correct length per note above. Insert the open end
of the 3/8” black tube into the drain quick connect tting on
the drain saddle.
