Thank you for your purchase of a state of the art Watts Premier Reverse Osmosis (RO) water treatment 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
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 particles like clean
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 clean water on the other. This is why RO systems produce
both clean drinking water and waste water that is ushed from the system. This reverse osmosis system also utilizes carbon
block ltration technology, and can therefore provide much higher quality drinking water than carbon ltration systems.
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 – 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 RO membrane. This semi-permeable membrane will
take out TDS & Sodium and a wide range of contaminants such as Perchlorate, Chromium, Arsenic, Copper, Lead,
as well as Cysts, such as Giardia and Cryptosporidium 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- VOC Block, recommend change 12 months.
Watts Premier WP-4V reverse osmosis system conforms to NSF/ANSI 58 for VOC reduction. Through the specialty
formulated VOC post lter your system is capable of reducing harmful Volatile Organic Chemicals (VOC) like
MTBE’s, Atrazine, Benzene, 2,4-D,Lindane and others from your drinking water. It is estimated that VOC’s are
present in one-fth of the nation’s water supplies. These water contaminants can enter ground water from a variety
of sources including localized use of herbicides and pesticides, gasoline or oil spills, leaking underground fuel tanks,
septic system cleaners, and chemicals used in the dry-cleaning industry. See performance data sheet for individual
contaminants and reduction performance.
Note: Filter 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, VOC’s 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. When
replacing the lter elements, pay special attention to any cleaning instructions. Should you have any further questions please
refer to our website at www.premierH2o.com or call our customer service dept. at 1-800-752-5582.

Hardness: Recommended hardness not to exceed 10 grains per gallon, or 170ppm. 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.
Installation must comply with state and local plumbing regulations. This system is intended to
be installed on the cold water line only.
Copper Tubing: Reverse Osmosis water should not be run through copper tubing as the purity of
the water will leach copper causing an objectional taste in water and pin holes may form in the tubing.
Watts Premier supplies speciality lters (part number 107008) that can be used if copper tubing
follows the Reverse Osmosis unit. Be sure to follow any state or local regulations during installation.
Operational Parameters
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 85 psi a pressure
regulator is recommended and if over 100 psi then a pressure regulator is required. Should you
need a gauge to check your water pressure, see page 19 (item no. 261003).

Make sure the surroundings of the sink are cooled before mounting the
faucet to the sink after drilling and remove all sharp edges.
Step 3
Step 4
Determine desired location for the RO faucet on your sink and place
a piece of masking tape on 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” 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
Drill a Hole for the Faucet in a Porcelain Sink
Punch a Hole for the Faucet in a Stainless Steel Sink
Drill a ¼” pilot hole. Use a
1
/ 2 ” Hole Punch and an adjustable wrench to
punch the hole in the sink. Change to the 1 ¼” Hole Punch to enlarge
the hole.
Step 5
The faucet can now be installed.
If mounting faucet to a Stainless Steel Sink you will need a 1 ¼”
Hole Punch. The faucet opening should be centered between the
back splash and the edge of the sink, ideally on the same side as
the vertical drain pipe.
Note:
Note: Most sinks are pre drilled with 1 ½” or 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 Premier accepts no responsibility for
damage resulting from the installation of faucet.

Drill Hole and Connect 3/8” Black Tube from Faucet to the Drain
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.
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.
Step 13
IMPORTANT:
Step 12
Step 15
Green Tube Connection
Step 14 Locate green tube attached to the RO Module. Remove a brass nut,
plastic sleeve and brass insert from the parts bag. To assemble,
place the brass nut on the green tube rst, then the sleeve (small
tapered end of sleeve must point to the end of tube) and then push
the brass insert all the way into the end of the tube. (See Picture)
Insert the green tube into the ¼” opening on the adapt-a-valve until
it stops. Slide the brass nut and sleeve down and thread onto the
male pipe threads. Use a ½” wrench to securely tighten the nut.
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 through the drain pipe.
Step 11
Caution: It is very important to keep the drill centered to prevent
damage of the drain saddle while drilling.
Step 10 The drain saddle must be mounted at least 1 ½” above the nut of the
P-trap or cross bar from the garbage disposal to insure proper drainage.
Assemble the drain saddle around the drain pipe at the best available
location. Using Phillips screw driver tighten screws evenly and securely
on both sides of the drain saddle. Keep the plastic compression nut off
at this time.
Caution: Do not over tighten the screws. It may crack the drain saddle.

How To Use the Quick Connect Fittings on the RO Module
To make a connection, the tube is simply pushed into the tting. The unique patented John Guest®
locking system holds the tube rmly in place without deforming it or restricting ow.
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 collect squarely against face
of tting. With the collet held in this position, the tube can
be removed. The tting can then be reused.
Connect the Blue Tube from the Faucet to RO Module
Step 23
Step 22
Connect the Red Tube from Faucet to RO Module
Insert the open end of the red 1/4” tube attached to the RO faucet
into the 1/4” X 1/4” quick connect tting on the RO Manifold. Make
sure the tube is pushed in all the way to the tube stop. (See Picture)
Insert the blue 3/8” tube from the faucet into the port on the module
marked “FAUCET”. Make sure the tube is pushed in all the way
to the tube stop.
A connection to a refrigerator / ice maker may be tee’d into this blue tube.

For Warranty card Please see page 25-26.
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 5) is complete and the
tank has been allowed to completely ll. 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 RO tank must
be allowed to ll up fully in order for the ice maker system to work properly.
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. Repeat this step
two more times. The fourth tank can be used for drinking.
Don’t Forget To Register!
Open the RO faucet and leave it open until water begins to trickle out (it will come out
slowly).
Step 5
Turn on the incoming cold water at the angle stop valve. Open the needle valve on the brass
Adapt-a-Valve by turning counter clockwise. Check the system for leaks and tighten any tting
as necessary. (Check frequently over the next 24 hours to ensure no leaks are present).

Tip: This is a good time to check the air pressure in your storage tank. For instructions
please see page 15.

Page 14
Membrane Replacement
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%.
Step 1
Step 3 Remove the horizontal membrane housing on top of the unit by
turning it counter clockwise to loosen.
Turn off the incoming water supply to the RO by turning the needle
valve on the adapt-a-valve clockwise until it stops. (Follow the green
tube away from the RO system to nd the adapt-a-valve.)
Pull rmly on the yellow RO membrane to remove it from the housing
and discard.
Lubricate the O-rings on the new membrane with a water soluble
lubricant such as KY Jelly ®. Insert the end with the two black
O-rings into the cap. Twist the membrane as you push it rmly into
the manifold.
Step 4
Step 5
Step 6 Replace the membrane housing onto the cap by turning clockwise.
Tighten securely.
A water sample may be sent to Watts Premier for a free diagnosis of your membranes
performace. To send a water sample, use two (2) clean containers and ll ½ cup of tap water
in one container and ½ cup of reverse osmosis 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.
Note:
Open the RO Faucet and allow water to drain from the tank until it
is completely empty.
Step 2
Before re-installing the membrane housing back on to the
system, check O-ring on the housing to make it is still in
place and lubricate with water soluble lubricant.
Caution:
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.
Step 7 Follow Start up instructions on page 11.

Procedure for Extended Non-Use (More than 2 months)
Turn off the water supply by turning the “T” on the adapt-a-valve clockwise until it stops and
open the RO faucet to empty the storage tank (Save a few ounces of RO water). Once the
storage tank is empty, remove the membrane and place it in a sealed plastic bag with the RO
water saved earlier and store in your refrigerator.
For restart, reinstall membrane and follow startup procedure on page 11.
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 by turning the needle
valve on the adapt-a-valve clockwise until it stops. (Follow the green
tube away from the RO system to nd the adapt-a-valve.)
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 a 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.

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. Maker sure water supply is turned on and Adapta
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 and clean ow restrictor.
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 Fouled membrane Replace membrane
High water pressure Check incoming water pressure to make sure it does not
exceed 100psi. A pressure relief valve may be necessary.
High air pressure in tank Empty storage tank of water. Set tank air pressure to 5
psi. See Page 15.
4. Noise from faucet or drain Air gap faucet Inherent sound with air-gap faucets.
Location of drain saddle See diagram for proper location of drain saddle.
Higher capacity membrane Normal with high capacity membrane
High water pressure Check incoming water pressure to make sure it does not
exceed 100 psi. A presser relief valve may be necessary.
5. Faucet leaks from Crimp or loop in drain line Straighten black 3/8 drain tube. Cut off any excess tubing
the air gap feature Drain tube clogged/restricted Caused from dishwasher or garbage disposal.
Disconnect the 3/8” black tube at the drain, clean the 3/8”
black tube out with a wire, then reconnect.
6. Small amount of water in System just starting up Normally it takes 4-6 hours to ll tank. Note: Low water
storage tank pressure and/or temperature can drastically reduce
production rate.
Low water pressure See #1 Above
Too much air in tank Add air if below 5 psi and bleed if above 5 psi. Check
only when tank is empty of water. See Page 15.
7. Water leaks from the Not properly tightened. Tighten the bowl
lter housing Missing or kinked O-ring Turn off the water supply. Release the pressure, remove
bowl and replace the O-ring. (p/n 113043). Make sure
the O-ring is seated in the lter bowl properly before
reinstalling the lter bowl.

Arsenic (As) is a naturally occurring contaminant found in many ground waters. Arsenic
in water has no color, taste or odor. It must be measured by an arsenic test kit or lab test.
Public water utilities must have their water tested for arsenic. You can obtain the results
from your water utility contained with in your consumer condence report. If you have
your own well, you will need to have the water evaluated. The local health department
or the state environmental health agency can provide a list of test kits or certied labs.
There are two forms of arsenic: pentavalent arsenic (also called As (V), As (+5)) and
trivalent arsenic (also called As (III), As (+3)). In well water, arsenic may be pentavalent,
trivalent, or a combination of both. Although both forms of arsenic are potentially hazardous
to your health, trivalent arsenic is considered more harmful than pentavalent arsenic.
RO systems are very effective at removing pentavalent arsenic. A free chlorine residual
will rapidly convert trivalent arsenic to pentavalent arsenic. Other water treatment
chemicals such as ozone and potassium permanganate will also change trivalent arsenic
to pentavalent arsenic. A combined chlorine residual (also called chloramine) where it
does convert trivalent arsenic to pentavalent arsenic, may not convert all the trivalent
arsenic in to pentavalent arsenic. If you get your water from a public water utility, contact
the utility to nd out if free chlorine or combined chlorine is used in the water system.
This Watts Premier reverse osmosis system is designed to remove up to 98% of
pentavalent arsenic. It will not convert trivalent arsenic to pentavalent arsenic. Under
laboratory standard testing conditions, this system reduced 0.30 mg/L (ppm) pentavalent
arsenic to under 0.010 mg/L (ppm) (the USEPA standard for drinking water). Actual
performance of the system may vary depending on specic water quality conditions at
the consumer’s installation. In addition to the independent laboratory standard testing
conditions Watts Premier has conducted additional eld testing on our reverse osmosis
units to determine trivalent arsenic reduction capabilities. Based upon Watts Premier eld
testing, it has been determined that the RO units are capable of reducing up to 67% of
trivalent arsenic from the drinking water.
The RO membrane component of this Watts Premier reverse osmosis system must
be maintained according to its recommended maintenance cycle. Specic component
identication and ordering information can be found in the installation/operation manual
maintenance section, by phone at 1-800-752-5582 or online www.premierH2o.com

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.
