Thank you for yourpurchase of a state of the artWatts Premier Reverse Osmosis (RO) watertreatment system.Water
quality concerns are becoming more of a focus for the public. You may have heard about contaminants in the drinking water
such as Arsenic, 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 5 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 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 cannot 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.

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
marksand that burrs and sharpedges 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.
Pullonthe tubeto checkthat itissecure. It isa goodpractice
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.

Helpful Installation Tips for the Watts Top Mount Faucet
During shipping/handling the tog-
gle 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 fol-
lowing 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.

Drain Saddle Installation
Step 7
Step 8
Step 9 The drain saddle must be mounted at least 1 ½” above the nut of the
P-traporcross barfrom thegarbagedisposal toinsureproper drainage.
Assemble the drain saddle around the drain pipe at the best available
location. UsingPhillips screwdrivertighten screwsevenly andsecurely
on both sides of the drain saddle. Keep the plastic compression nut off
at this time.
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 as shown.
1 Black compression nut 1 Semicircle bracket with opening
2 Screws 1 Foam gasket
2 Nuts for screws 1 Semicircle bracket
Gather the pieces of the drain saddle:
Caution: Do not over tighten the screws. It may crack the drain saddle.
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. If no other installation of drain line is available, Watts
Premieroffers drain lineinstallationkit (part number 164020)thatcan be used
with garbage disposals.
Caution:
Drill hole and Connect 3/8” Black Tube from Faucet to the Drain Saddle
The black 3/8” drain tube must be as SHORT and STRAIGHT as possible 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.
IMPORTANT:
With the drain saddle secured onto the drain pipe, using a 1/4”
drill bit installed in your electric drill, insert the drill bit through the
opening in the drain saddle and drill into the drain pipe.
Step 10
Caution: It is very important to keep the drill centered to prevent
damage of the drain saddle while drilling.
Measure the 3/8” black tube from faucet to the drain saddle on the
drain pipe and make a straight cut to the correct length.
Slip black tube through black compression nut. Insert black tube
into the opening in the drain saddle and hand tighten the black nut,
and add 1/4 turn with a wrench.

Startup Instructions
If you have connected your RO system to a refrigerator / ice maker, make sure the ice maker is
off (do not allow water to ow to the ice maker) until ushing (Step 4) is complete and the tank
has been allowed to ll completely. Connection from the RO to the ice maker system should
have an in-line valve installed before the ice maker so it can easily be closed to prevent water
owing to the ice maker during start up and periodic maintenance. Your storage tank must be
allowed to ll up fully in order for the ice maker system to work properly.
After the storage tank has lled open the RO Faucet to ush the tank completely. You will
know that the tank is empty when the ow rate from the RO faucet is down to a trickle. Repeat
this step two more times. The fourth tank can be used for drinking.
Open the RO faucet and leave it open until water begins to trickle out (this may take a few
minutes and the water will come out slowly).
Step 4
Turn on the incoming cold water at the angle stop valve and the
Adapt-a-Valve. Check the system for leaks and tighten any ttings
as necessary. (Check frequently over the next 24 hours to ensure
no leaks are present).
Step 3
Step 2
Note:
Step 1
Close the RO faucet allowing the storage tank to ll with water. It may take 3 to 6 hours to
ll the tank completely depending on the production capability of the membrane, local water
temperature and water pressure.
Flushing of the tank 3 times is only necessary during the initial startup and after replacing the
membrane.
During the ll period you may hear water trickling which is a normal occurrence.
Note:
Note:
Congratulations!
You have completed the installation of your new Reverse Osmosis system.
Please Follow the Startup Instructions.
The ushing process should take about a day to complete.

Place a towel under the RO module to catch any excess water that
may drip out from the lters during the changeover.
Step 1
Your RO module is equipped with valve heads which will automatically turn off the water supply to each
lter when the lter is released, thus you do not need to turn off the incoming water supply at the Adapt-
a-Valve. The RO faucet must be off when lters are replaced. To make the removal of the lter cartridges
easier, the heads & cartridges may be swiveled up to 90 degrees as shown in the pictures below.
Step 2
To install a lter cartridge: Remove the seal cap and insert
the cartridge into the valve head until you hear an audible “click”
(the button does not need to be pressed to install new lters).
Step 3
To remove a lter cartridge: Push & hold the button on the
valve head above the lter. Pull cartridge downward (from the
head) to remove. Release button and discard old lter.
Changing The Filter Cartridges
Membrane Replacement (2 - 5 Years)
√ One Membrane (50 GPD Green Label P/N: 105331)Replace:
Membranes have a life expectancy between 2 and 5 years, depending on the incoming water conditions
and the amount the RO system is used. This reverse osmosis membrane is critical for effective reduction of total
dissolved solids (TDS). The product water should be tested periodically to verify that the system is performing
satisfactorily.
Normally, a membrane would be replaced during a semiannual or annual lter change. However, if at any
time you notice a reduction in water production or an unpleasant taste in the reverse osmosis water, it could be
time to replace the membrane. Watts Premier recommends replacing the membrane when TDS reduction falls
below 75%.
A water sample may be sent to Watts Premier for a free diagnosis of your membranes performance. To
send a water sample, use 2 clean containers and ll 1/2 cup of tap water in one container and 1/2 cup of RO
water in 2nd container. Clearly label each sample. Send the samples to the address listed on the cover of this
manual attention “Water Samples”. Watts Premier will test the water and mail or call you with the results.
To reset the electronic monitor during replacement of lters, simply
slide out the battery from the base of the faucet and reinsert.
Note:
This reverse osmosis system contains a replaceable component (the RO membrane) which is critical to the
efciency of the system. Replacement of this reverse osmosis membrane should be with one of identical speci-
cations as dened by Watts Premier to assure the same efciency and contaminant reduction performance.
Annual Maintenance-(Sanitization Recommended See PG.16)
√ One sediment lter (Red Label P/N: 105311)
√ One carbon pre-lter (Yellow Label P/N: 105351)
√ One carbon post-lter (Blue Label P/N: 105341)

6 Month System Maintenance
Tip: This is a good time to check the air pressure in your storage
tank. For instructions please see page 16.
Flush rst tank full after completing the annual maintenance.
Note:

Page 16
Annual Sanitization
Using a clean eye dropper insert ½ teaspoon of hydrogen peroxide or
common household bleach into the blue tube. This will ow into the
tank once water is turned back on to unit. Reattach blue tube to the
ball valve. Follow startup procedure and drain two full tanks of water.
Replace carbon Post-lter.
Turn off the water supply to your RO system at the adapt-a-valve and
open the RO faucet to drain the storage tank.
Sanitization procedure must be performed before a lter change.
Note:
Step 1
Step 3
Step 2 Disconnect the blue tube from the ball valve on the storage tank (see
page 7 for quick connect tting use instructions).
Once all water in the tank is purged, check air pressure using an air pressure gauge, it should
read between 5 - 7 PSI. (Digital air pressure gauge is recommended)
Check Air Pressure in the Tank
Important:
Step 3
Check air pressure only when tank is empty of water!
Step 1 Turn off the incoming water supply to the RO.
Open the RO Faucet and allow water to drain from the tank until
it is completely empty.
Step 2
Check air pressure in the storage tank when you notice a decrease in available water from
the RO system. Air can be added with a bicycle pump using the schrader valve that is located
on the lower side of the tank behind the blue plastic cap.
Tip: When water from the RO faucet slows to a trickle, with the faucet still in the open
position, you may add air to the tank to purge any left over water, this will ensure that
the tank is completely empty.

Procedure for Extended Non-Use (More than 2 months)
Turn off the water supply to your RO system at the adapt-a-valve and open the RO faucet to
drain the storage tank. Once the storage tank is empty, remove all lter cartridges (order not
important), place them into a sealed plastic bag and store in your refrigerator.
DO NOT FREEZE
To Restart System:
If you have connected your RO system to a refrigerator / ice maker, make sure the ice
maker is off (do not allow water to ow to the ice maker) until the tank has been allowed
to completely ll.
After the Tank has lled, open the RO Faucet to ush the tank completely. You will know that
the tank is empty when the ow rate from the RO faucet is down to a trickle. The second tank
can be used for drinking.
Open the RO faucet and leave it open until water begins to trickle out (it will come out
slowly).
Step 5
Turn on water supply to the system at the Adapt-a-Valve.
(Check frequently over the next 24 hours to ensure no leaks are present).
Step 4
Step 3
Note:
Step 2
Close the RO faucet allowing the storage tank to ll with water. It may take 3 to 6 hours to
ll the tank completely depending on the production capability of the membrane, local water
temperature and water pressure.
Reinstall all lters on to the RO unit. Filters are color coded to match the lter heads they
snap in to. Refer to page 15 step three for cartridge installation procedure.

TROUBLE SHOOTING
Problem Cause Solution
1. Low/Slow Production Low Water Pressure Assure a minimum of 40 psi incoming water pressure.
Premier sells a booster pump if home water pressure is
low. Make surewater supplyis turnedonandfeedwater
valve is all the way open.
Crimps in tubing Check tubing and straighten or replace as necessary.
Clogged pre-lters Replace pre-lters.
Fouled membrane Replace membrane.
2. Milky colored Water Air in system Air in the system is a normal occurrence with initial
start up of the RO system. This milky look will
disappear during normal use within 1-2 weeks. If
condition reoccurs after lter change, drain tank 1 to 2
times.
3. Water constantly Low water pressure See #1 Above
running, unit will not
shut off Crimp in supply tube Check tubing and straighten or repair as necessary.
High water pressure Check incoming water pressure to make sure it does
not exceed 80 psi. A pressure relief valve may be
necessary.
High pressure in Tank Empty storage tank of water. Set tank air pressure
between 5-7 psi. See previous page.
Low Pressure in Tank Use a Digital Air Gauge for best results. The empty
tank pressure should be 5-7 psi. See page 16.
4. Water from faucet Crimp or restriction Check tubing and straighten or repair as necessary.
vent hole or noise from in drain line Straighten all drain lines. Clear blockage. Cut off any
drain. Excess tubing
Drain tube clogged Caused from dishwasher or garbage disposal.
Disconnect the 3/8” black line at the drain, clean the
3/8” black line out with a wire, then reconnect. Blowing
air through the line will not always remove the clog.
5. Small amount of water in System starting up Normally it takes 4-6 hours to ll tank. Note: low
storage tank incoming water pressure and/or temperature can
drastically reduce production rate.
Low water pressure See #1 above.
Too much air in tank Tank air pressure should be 5-7 psi when empty of water.
If below 5 psi add air or bleed if above 7 psi.
Check only when tank is empty of water.
See previous page.
6. Low water ow from faucet Check air pressure in tank Use a Digital Air Gauge for best results. The empty
tank pressure should be 5-7 psi. See page 16.

This system has been tested according to NSF/ANSI 58 for reduction of the substances listed below. The concentration of the indicated substances in water
entering the system was reduced to a concentration less than or equal to the permissible limit for water leaving the system as specied in NSF/ANSI 58. This
system has been tested for the treatment of water containing pentavalent arsenic (also known as As (V), As (+5), or arsenate) at concentrations of 0.30 mg/L or
less. This system reduces pentavalent arsenic, but may not remove other forms of arsenic. This system is to be used on water supplies containing a detectable free
chlorine residual at the system inlet or on water supplies that have been demonstrated to contain only pentavalent arsenic. Treatment with chloramine (combined
chlorine) is not sufcient to ensure complete conversion of trivalent arsenic to pentavalent arsenic, Please see the Arsenic Facts section of the Performance Data
Sheet for further information.
