Thank you for your purchase of a state of the art W atts Premier Reverse Osmosis (RO) water treatment system. W ater
quality concerns are becoming more of a focus for the public. You may have heard about contaminants in the drinking water
such as Arsenic, Perchlorate, Chromium, Cryptosporidium or Giardia. There may also be some local water issues such as
high levels of Lead and Copper. This Watts Premier water treatment system has been designed and tested to provide you
with high quality drinking 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 only certain particles
like clean drinking water, but not other particles like arsenic and lead.
Reverse osmosis uses a semi permeable membrane; however, by applying pressure across the membrane, it concentrates
contaminants (like a strainer) on one side of the membrane, producing crystal clear water on the other. This is why RO
systems produce both clean drinking water and rinse water that is ushed from the system. This reverse osmosis system also
utilizes carbon block ltration technology, and can therefore provide a higher quality drinking water than carbon ltration
systems alone.
Your system is a four stage RO which is based upon separate treatment segments within the 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 – Carbon lter, recommended change 6 months.
The second stage contains a ve micron 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 2-5 years.
Stage three is the heart of the reverse osmosis system, the 50GPD (Gallons Per Day) RO membrane. This semi
permeable membrane will effectively remove TDS, Sodium and a wide range of contaminants such as Percholate,
Chromium, Arsenic, Copper, Lead as well as Cysts, such as Giardia and Cryptosporidium. 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- Carbon post lter, recommend change 12 months.
The nal stage is a high quality carbon lter. Drinking water enters this lter after the water storage tank and it is
used as a nal polishing lter.
Note: Filter & Membrane life may vary based upon local water conditions and/or use patterns.
System Maintenance
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.
It is important to change out your lters at the recommended intervals as indicated in this system manual. When replacing
the lter elements, pay special attention to any cleaning instructions. Should you have any further questions please refer to
our web site at www.wattspremier.com or call our customer service department at 1-800-752-5582.
With proper installation and maintenance, this system will provide you with high quality water for years to come.
All of Premier’s water enhancement products are rigorously tested by independent laboratories for safety and reliability.

Operational Parameters
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.
Operating Temperatures: Maximum 100°F (37.8°C) Minimum 40°F (4.4°C)
Operating Pressure: Maximum 100 psi (7.0 kg/cm
2
) Minimum 40 psi (2.80 kg/cm
2
)
pH Parameters: Maximum 11 Minimum 2
Iron: Maximum 0.2 ppm
TDS (Total Dissolved Solids) < 1800 ppm
Turbidity < 5 NTU
Hardness Maximum 10 Grains Per Gallon *
Hardness: Recommended hardness not to exceed 10 grains per gallon, or 170 parts per million.
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.
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.
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.

Drill a Hole for the Reverse Osmosis Faucet
Marble Counter-top
We recommend contacting a qualied contractor for drilling a hole in a marble counter-top.
Counter Top / Porcelain & Stainless Steel Sink
Note:
Step 1
Step 2
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.
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.
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).
Step 3
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 4
After drilling, remove all sharp edges and make sure the surroundings
of the sink are cooled before mounting the faucet.
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.
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.
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.
Fitting grips before it seals. Ensure tube is pushed into
the tube stop.
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.

Helpful Installation Tips for the Watts Top Mount Faucet
During shipping/handling the toggle bolt on your new faucet may
push up out of position. Prior to the
install, hold the faucet as shown in
the picture and pull down on the
wing nut. This will ensure that the
O-rings are in their proper position
and that your faucet will have a
good seal.
Disassembling your faucet is never
recommended as this could void
your warranty. If it is necessary to
remove the fitting at the end of the
toggle bolt you must follow the following procedure for re-assembly.
Prior to re-connecting the fitting
to the toggle bolt, you must insert
the 3/8” blue tube into the fitting.
There are small O-rings inside of
the fitting that could be pushed out
of position if the blue tube is not
fully inserted first. Failure to do so
may cause the faucet to leak.
