Watts Premier RO-PURE Plus Installation, Operation And Maintenance Manual page 2

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, 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 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 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 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.
Premier RO-Pure Plus system conforms to NSF/ANSI 58 for VOC reduction. 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.
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
