Thank you for your purchase of a state of the art Watts 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 Watts 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 some 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 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.
Your system is a four or five 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 and 3 – Carbon filters, recommended change 6 months.
The second and third stages each contain a 5 micron carbon block filter. This helps ensure that chlorine and other
materials that cause bad taste and odor are greatly reduced.
Stage 4- Membrane, recommended change 2-5 years.
Stage four is the heart of the reverse osmosis system, the RO membrane. This semi permeable membrane will
effectively take out 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 5- Carbon in-line filter, recommend change 6 - 12 months.
The final stage is an in-line granular activated carbon (GAC) filter. This filter is used after the water storage tank,
and is used as a final polishing filter.
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 filter elements, other bad tastes and odors will
be apparent in your drinking water.
This is why 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
