Thankyouforyourpurchase ofa stateof theart PremierReverseOsmosis(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
asArsenic, Chromium, Cryptosporidium or Giardia. There may also be some local water issues such as high levels of Lead
and Copper. This 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.Asemi 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 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.
Premier WP4V-50 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.
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
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.

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 ts standard 1 ¼” – 1 ½” drain pipes
Drain Saddle Installation
Step 11
Step 12
Step 13 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 3/8” 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 as shown.
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, Premier
offers drain line installation kit (part number 164020) that can be used with
garbage disposals.
Caution:
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:
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.
Connect the black tube to the open quick connect tting on the drain
saddle by pushing the tube all the way to the tube stop.
Step 16
Step 15
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.

Start up 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 (the water trickling has stopped), 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:

Membranes have a life expectancy between 2 and 5 years, depending on the incoming water conditions
andtheamounttheRO systemis used.Thisreverse osmosismembrane iscriticalfor effectivereduction
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. Premier recommends replacing the membrane when
TDS reduction falls below 75%.
NOTE: A water sample may be sent to Premier for a free diagnosis of your
membranes performance. 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”. Premier will test the water and mail or
call you with the results.
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 find the adapt-a-valve.)
Step 2: Open the RO Faucet and allow water to drain from the tank until it is
completely empty.
Step 3: Remove the horizontal membrane housing on top of the unit by
turning it counter clockwise to loosen.
Step 4: Pull firmly on the yellow RO membrane to remove it from the
housing and discard.
Step 5: 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 firmly into
the manifold.
NOTICE: 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.
Step 6: Replace the membrane housing onto the cap by turning clockwise.
Tighten securely.
Step 7: Follow Start up instructions on page 12.
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 identi-
cal specications as dened by Premier to assure the same efciency and contaminant reduction perfor-
mance.
NOTICE: This is a good time to check the air pressure in your storage tank. For instructions please
see page 16.
Step 12: Follow Steps 8 through 10 in the Six Month System Maintenance (Page 13) for startup
directions.

Page 16
Procedure for Extended Non-Use (More than 2 months)
Turn off the water supply to the RO system at the adapt-a-valve 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 12.
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 posi-
tion, 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 16.
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 3-6 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 16.
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.
Publicwaterutilitiesmusthavetheirwatertestedforarsenic.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
asozone and potassium permanganate will alsochange 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 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 Premier has conducted additional eld testing on our
reverse osmosis units to determine trivalent arsenic reduction capabilities. Based upon 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 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
