Instructions / Assembly

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, Perchlorate, 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 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 three or four stage RO which is based upon separate treatment segments within the one complete water
filtration system. These stages are as follows:
Stage 1 (Not in three stage units) – 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 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 filter, recommend change 6 - 12 months.
The final stage is a high quality carbon filter. Drinking water enters this filter after the water storage tank and it is
used as a final polishing filter.
Note: Filter life may vary based upon local water conditions 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 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
