Thank you for your purchase of a state of the art 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, Perchlorate, 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 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 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.premierH2o.com or call our customer service department at 1-800-752-5582.

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. Premier accepts no responsibility for
damage resulting from the installation of faucet.

Page 6
Faucet Installation (Actual RO Faucet may vary)
Feed both the red and black tubing through the pre drilled hole in the sink/counter until faucet
is seated.
Locate one of the two 1/4” blue tubes in the box. In the faucet parts bag locate a compression
nut, plastic ferrule sleeve and a plastic tube insert. To assemble - place the compression nut
on the open end of the blue tube rst, then the plastic ferrule sleeve small tapered end of
sleeve must point to the end of tube, push the white plastic insert into the end of blue tubing
with the ferrule sleeve, insert the blue tube into the faucet stem and tighten compression nut.
DO NOT overtighten nut.
Step 6
Step 7

Adapt-a-Valve Installation - Part# 134007
Turn off the cold water supply to the faucet by turning the angle stop valve completely off.
Step 8
Step 9 Attach the adapt-a-valve as illustrated in the three photos above, choosing the conguration
that ts your plumbing. (When attaching the adapt-a-valve to straight pipe threads, use Teon
tape on the threads without the rubber washer.)
Caution: Water supply line to the system must be from the cold water supply line only.
Hot water will severely damage your system.
Drain Saddle ts standard 1 ¼” – 1 ½” drain pipes
Drain Saddle Installation - Part# 164016
Step 10
Step 11
Step 12 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.
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, Premier
offers drain line installation kit (part number 164020) that can be used with
garbage disposals.

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 15
IMPORTANT:
Step 14
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 13
Caution: It is very important to keep the drill centered to prevent
damage of the drain saddle while drilling.
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.

Green Tube Connection
Step 16 Locate the 1/4” green tubing in the box. Located on the back side of the RO system are
three 1/4” quick connect ttings. Connect one end of the green tube to the tting behind the
Sediment Filter head (Red Label) by pushing rmly into the tting. (See Picture Above)
Blue Tube Connections
Step 17 Locate the second 1/4” blue tube in the box. Connect this 1/4” blue tube to the 1/4” quick
connect elbow tting located on the back side of the RO system directly behind the Pre-
Carbon lter head (Yellow Label) by pushing rmly into the tting. Connect the 1/4” blue
tube from the RO Faucet to the 1/4” quick connect tting located on the back side of the
RO system behind the Post-Carbon lter head (Blue Label) by pushing rmly into the tting.
(See Picture Above)
Connect Green tube to the Adapt-a-Valve
Step 18 Insert the green tube attached to the RO system into the ¼” Quick Connect opening on the
adapt-a-valve until it stops. Approximately 3/4” of the tube should insert into the adapt-a-valve
tting.

* Remove Red protective plugs before tube installation!
NOTE
Reverse Osmosis Module Mounting
Step 19 Determine best location for the RO module to be mounted to allow
for future system maintenance. The parts bag has 2 self tapping
screws. Using an electric drill with a Phillips bit, screw them into
the cabinet wall 9.25” apart and 12” from the bottom of the cabinet.

Page 10
Blue Tube Connection (From The RO Module To TANK)
Position tank in desired location. Stand it upright or lay it on its
side (using the black plastic stand). Locate the open end of the
1/4” blue tube connected earlier to the elbow on the back of the
RO unit behind the Pre-Carbon lter (Yellow Label). Insert the
tube into the quick connect tting on the tank ball valve. Make
sure the tube is pushed in all the way to the tube stop.
(See Picture to the Right)
Step 23
Teon tape must be applied in a clockwise direction. Wrap
(7 to 12 turns) around the male pipe threads (MPT) on the
stainless steel tting on top of the tank.
Tank Ball Valve Installation - Part#: 134018
Thread the quick connect ball valve (supplied in the parts bag)
onto the stainless steel connector on the tank.
Note: Do not over-tighten plastic connections.
Step 21
Step 22
Note: Set the blue ball valve knob in-line with the blue tube, this is the “open” position.
Red Tube Connection (From RO FAUCET To The RO Module)
The RO Membrane (Green Label) has a 1/4” quick connect tting located on the bottom of
the cartridge. Remove the red protective cap and insert the 1/4” quick connect elbow stem
located on the end of the 1/4” red faucet tubing into the 1/4” quick connect tting on the
bottom of the RO membrane lter (Green Label) making sure it is pushed in all the way to
the tube stop.

Start up Instructions
Register by mail, phone, fax or internet. Premier uses this information only to provide a lter
change reminder notice. Pre-lters should be changed every 6 months and the Post Carbon
lter annually. You may register your warranty via our web site at
www.premierH2o.com or call 1-800-752-5582 (within USA only) / FAX#: [phone].
For Warranty card Please see page 23-24.
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.
The ushing process should take about a day to complete.
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. Make sure that the ball valve on top of the storage tank is in the open position
- blue handle is in line with the blue tube.
(Check frequently over the next 24 hours to ensure no leaks are present).
Step 4
Step 3
Step 2
Step 1
Close the RO faucet allowing the storage tank to ll with water. It may take 4 to 6 hours to
ll the tank completely depending on the production capability of the membrane, local water
temperature and water pressure.
Congratulations!
You have completed the installation of new your Reverse Osmosis system.
Please Follow the Startup Instructions.
Note: During the ll period you may hear water trickling due to the Reverse Osmosis Process.
Flushing of the tank 3 times is only necessary during the initial startup and after replacing the
membrane.
Note:

Page 12
6 Month System Maintenance
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 valved 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 valved head twisting it clockwise until full seated.
Step 3
To remove a lter cartridge: Twist lter cartridge counter
clockwise until cartridge pops out of the lter head.
Changing The Filter Cartridges
Membrane Replacement (2 - 5 Years)
√ One Membrane (50 GPD Green Label P/N: 114110)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. Premier recommends replacing the membrane when TDS reduction falls below
75%.
A water sample may be sent to 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”. 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 Premier to assure the same efciency and contaminant reduction performance.
Annual Maintenance -(Sanitization Recommended See PG.13)
√ One sediment lter (Red Label P/N: 114105)
√ One carbon pre-lter (Yellow Label P/N: 114106)
√ One carbon post-lter (Blue Label P/N: 114107)

Annual Sanitization
Procedure for Extended Non-Use (More than 2 months)
Turn off the water supply to your RO system by turning the “T” on the adapt-a-valve clockwise
1/4 turn 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.
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 6
Open the Adapt-a-Valve by turning it counter clockwise 1/4 turn.
(Check frequently over the next 24 hours to ensure no leaks are present).
Step 5
Step 4
Note:
Step 2
Close the RO faucet allowing the storage tank to ll with water. It may take 3 to 5 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 12 step three for cartridge installation procedure.
Step 1
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 start up procedure and drain the rst two full tanks
of water.
Turn off the water supply to your RO system by turning the “T” on the
adapt-a-valve clockwise 1/4” turn and open the RO faucet to drain the
storage tank.
Sanitization procedure should 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 9 for quick connect tting use instructions).

Page 14
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. Make 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.
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 14.
4. Noise / 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

This system has been tested according to 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 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.

Efciency rating means the percentage of the inuent water to the system that is available to the user as reverse osmosis treated water under
operating conditions that approximate typical daily usage. Recovery rating means the percentage of the inuent water to the membrane portion
of the system that is available to the user as reverse osmosis treated water when the system is operated without a storage tank or when the
storage tank is bypassed. There is an average of 4 gallons of reject water for every 1 gallon of product water produced.

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 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.
This reverse osmosis system contains a replaceable component critical to the efciency
of the system. Replacement of the reverse osmosis component should be with one of
identical specications, as dened by the manufacturer, to ensure the same efciency
and contaminant reduction performance. Specic component identication and ordering
information can be found in the maintenance section of this manual, by phone at 1-800-
752-5582 or online at www.premierH2o.com
