Thank you for your purchase of a state of the art Premier Reverse Osmosis (RO) water treatment system. Water
quality concerns are quickly becoming more of a focus for the public. Lately 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 in your
area 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 crystal clear water on the other. This is why RO
systems produce both clean drinking water and waste water that is flushed from the system. This reverse osmosis system also
utilizes carbon block filtration technology, and can therefore provide a higher quality drinking water than carbon filtration
systems alone.
Your system is a four stage RO which is based upon four separate treatment segments within the one complete water filtration
system. These stages are as follows:
Stage 1 – Sediment filter, recommended change 6 months.*
The first stage of your RO system is a five micron sediment filter that traps sediment and other particulate matter
like dirt, silt and rust which affect the taste and appearance of your water.
Stage 2 – Carbon filter, recommended change 6 months.*
The second stage contains a 5 micron carbon block filter. 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
effectively take out TDS, Sodium and heavy metals such as arsenic, copper, and lead, as well as Cysts, such as
Giardia and cryptosporidium. Because the process of making this high quality drinking water takes time, your RO
water treatment system is equipped with a storage tank.
Stage 4- Carbon Block, recommend change 6 months.*
The final stage is a carbon block filter. Some RO units are equipped with a standard filter which is used as a final
polishing filter. Some units are equipped with a specialty volatile organic chemical (VOC) reducing block.
This specialty filter will reduce other organic chemicals such as herbicides and pesticides that may be in
your water.
System Maintenance
Just because you can not taste it, does not mean that it is not there. Contaminants such as lead, chromium and arsenic (to
name a few) are undetectable to the taste. Additionally, over time if you do not replace the filter element, other bad tastes
and odors will be apparent in your drinking water.
This is why it is important to change out your filter at the recommended intervals as indicated in this system manual. When
replacing the filter 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.
*KP-4 R.O. unit is equipped with annual filters, therefore require only one annual filter change.

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
Drilla¼” pilothole. Use a
1
/ 2 ”HolePunch andan adjustablewrenchto
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.

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 Saddle
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 flow into the drain properly. Water may back up and come out the air
gap hole in the back of the faucet.
Step 17
IMPORTANT:
Step 16
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 6” apart and 16” from the bottom of the cabinet.
Do not cut any RO system tubes at this timeNote:
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 15
Caution: It is very important to keep the drill centered to prevent
damage of the drain saddle while drilling.
Green Tube Connection
Step 18 Locate green tube attached to the RO Module. Insert the open end of the green 1/4” tube
into the open 1/4” quick connect fitting on the plastic water feed valve making sure the tube
is pushed in all the way to the tube stop.
Threadthe plasticelbow(suppliedinthe partsbag) ontothe stainless
steel connection on the top of tank. Tighten using an adjustable
wrench. Do not over tighten as plastic could crack.
Step 20
Step 21
Wrap (7 to 12 turns) of Teflon tape clockwise around the male pipe
threads (MPT) on the Stainless Steel fitting on top of the tank.
Tank Elbow Installation
Do not let the tape cover the opening.
Note:

Page 9
Connect Blue Tube from “TANK” Port on RO Module to the Tank
Position tank in desired location. Stand it upright or lay it on its side (using the black plastic
stand). Measure the blue tube from the RO module port marked “TANK” over to the tank
and cut it to desired length.
Insert the blue 3/8” tube into the compression side of the elbow previously installed on top of
the storage tank and push in as far as it will go. Tighten the compression nut securely with a
wrench.
Step 22
Step 23
How To Use the Quick Connect Fittings on the RO Module
To make a connection, the tube is simply pushed into the fitting. The unique patented John Guest®
locking system holds the tube firmly in place without deforming it or restricting flow.
It is essential that the outside diameter be free of score
marks and that burrs and sharp edges be removed before
inserting into fitting.
Fitting grips before it seals. Ensure tube is pushed into
the tube stop.
Push the tube into the fitting, to the tube stop. The collet
(gripper) has stainless steel teeth which hold the tube
firmly in position while the O-ring provides a permanent
leak proof seal.
Pullonthetubeto check that itissecure. Itis 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 fitting. With the collet held in this position, the tube can
be removed. The fitting can then be reused.

Membrane Replacement
Membranes have a life expectancy between 2 and 5 years, depending on the incoming water conditions and the
amountthe RO system is used.This reverse osmosismembraneiscriticalfor effectivereductionof 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 filter 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%.
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 at the adapt-a-valve.
(Follow the green tube away from the RO system to find the adapt-
a-valve.)
Pullfirmly onthe yellowRO membraneto removeitfromthehousing
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 firmly 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 Premier for a free diagnosis of your membranes performace. To
send a water sample, use two (2) clean containers and fill 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.
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 efficiency of
the system. Replacement of this reverse osmosis membrane should be with one of identical specifications as defined by
Premier to assure the same efficiency and contaminant reduction performance.
Step 7 Follow Start up instructions on page 11.

Page 15
Procedure for Extended Non-Use (More than 2 months)
Turn off the water supply to the RO 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 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 at the adapt-a-valve.
(Follow the green tube away from the RO system to find 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-filters Replace pre-filters.
Fouled membrane Replace membrane and clean flow 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 filter change, drain tank 1 to 2 times.
3. Water constantly Low water pressure See #1Above
running unit will not
shut off Fouled membrane Replace membrane
High water pressure Check incoming water pressure to make sure it does not
exceed 100 psi. A presser relief valve may be necessary.
High air pressure in tank Empty storage tank of water. Set tank air pressure to 5
psi. See previous page.
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 6-10 hours to fill tank. Note: Low
storage tank pressure and/or temperature can drastically reduce
production rate.
Low water pressure See #1Above
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 previous page.
7. Water leaks from the Not properly tightened. Tighten the bowl
filter 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 filter bowl properly before
reinstalling the filter bowl.

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 confidence 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 certified labs.
Thereare twoformsof arsenic:pentavalent arsenic(alsocalledAs (V),As(+5))andtrivalent
arsenic (also called As (III),As (+3)). In well water, arsenic may be pentavalent, trivalent,
or a combination of both. Although both forms of aresenic 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) may not
convert all the trivalent arsenic. If you get your water from a public water utility, contact
the utility to find 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.Itwillnotconverttrivalentarsenictopentavalentarsenic.Underlaboratorystandard

This system has been tested according to NSF/ANSI 58 for reduction of the substances 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 specified 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
sufficient to ensure complete conversion of trivalent arsenic to pentavalent arsenic, Please see the Arsenic Facts section of the Performance Data Sheet for further
information.

Depending on water chemistry, water temperature, and water pressure Premier’s R.O. Systems production and performance will vary.
Efficiency rating means the percentage of the influent 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 influent 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.
