Overview
Thank you for your purchase of a state of the art Premier ZeroWaste® Reverse Osmosis 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 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.
About Reverse Osmosis
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 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
What Makes This Unit ZeroWaste
Normally, reverse osmosis sends more water to the drain than what ends up as drinking water. This flushing is necessary for reverse osmosis to work. This unit features a ZeroWaste
be sent to the drain and redirects it into your hot water connection where it can be re-used.

The Stages of Filtration
Your system is a four stage RO which is based upon 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 50GPD (Gallons Per Day) RO membrane. This semi permeable membrane will effectively remove Total Dissolved Solids (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- VOC Block filter, recommend change 12 months.
Through the specialty (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-fifth 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 & Membrane life may vary based upon local water conditions and/or use patterns.

Using Quick-Connect Fittings
Cutting Connecting
Make certain to push the tubing completely into the connector until it comes into contact with the internal tubing
stop. The collet (gripper) has stainless steel teeth which
Cut the tube square. It is essential that the outside diameter be free of score marks and that burrs and sharp edges
be removed before inserting into fitting.
hold the tube firmly in position while the O-ring provides a
permanent leak proof seal.
Pull on the tube to check that it is secure. It is good practice to test the system prior to leaving the site and/or
before use.
Disconnecting
BEFORE INSTALLATION
To disconnect, ensure the system is depressurized before
removing the tube. Push in collet squarely against the face
of the fitting. With the collet held in this position, the tube
can be removed. The fitting can then be reused.
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 filter elements, other bad tastes and
odors will be apparent in your drinking water.
It is important to change out your filters 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 web site at www.premierH2o.com or call our customer service department at 1-800-752-5582.
Installation Notes
• Not recommended for use on homes equipped with tankless water heaters. Contact Watts Premier for specific
details regarding this unit and tankless water heaters.
• System was tested in a laboratory setting utilizing a hot water heater of 40 gallons set at 120º F. Performance may
vary if your heater is smaller than 40 gallons or set above 120º F, contact the manufacturer for additional details.
• System should not be used on homes equipped with a backflow prevention device on the hot water heater.
• RO unit must be installed a minimum of 25 Pipe feet from water heater
• A non-switched outlet is needed to provide power to the pump.

Operational Parameters
NOTICE
Installation must comply with state and local plumbing regulations.
BEFORE INSTALLATION
NOTICE
* Hardness: Recommended hardness not to exceed 10 grains per gallon, or 170 parts per million. 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.
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 100 psi then a water pressure regulator is required. A booster
pump is needed for incoming water pressure under 40psi.
Copper Tube: Reverse Osmosis water should not be run through copper tube as the purity of the water will leach copper causing an undesired taste in water and pin holes may form in the tube.
Do not use with water that is microbiologically unsafe or of unknown quality, without adequate
disinfection before or after the system.

Drill a Hole for the Faucet in a Porcelain Sink
INSTALLATION
NOTICE
For Marble Counter-tops, we recommend contacting a qualified contractor for drilling a hole in a
marble counter-top.
Note: Most sinks are predrilled with 1½” or 1¼” diameter hole that you can use for your Drinking Water faucet.
(If you are already using it for a sprayer or soap dispenser, see Step 1).
NOTICE
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.
Step 1: 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 2 : 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).
Step 3: Using a 1.25” 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 4: After drilling, remove all sharp edges and make sure the surroundings of the sink are cooled before
mounting the faucet.
