Watts Premier RO-Pure Installation, Operation And Maintenance Manual page 4

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 fl ushed from the system. This reverse osmosis system also
utilizes carbon block fi ltration technology, and can therefore provide a higher quality drinking water than carbon fi ltration
systems alone.
Your system is a three or four stage RO which is based upon separate treatment segments within the one complete water
fi ltration system. These stages are as follows:
Stage 1 (Not in three stage units) – Sediment fi lter, recommended change 6 months.
The fi rst stage of your RO system is a fi ve micron sediment fi lter that traps sediment and other particulate matter
like dirt, silt and rust which affect the taste and appearance of your water.
Stage 2 – Carbon fi lter, recommended change 6 months.
The second stage contains a 5 micron carbon block fi lter. 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 fi lter, recommend change 6 - 12 months.
The fi nal stage is a high quality carbon fi lter. Drinking water enters this fi lter after the water storage tank and it is
used as a fi nal polishing fi lter.
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 fi lter elements, other bad tastes and odors will
be apparent in your drinking water.
This is why it is important to change out your fi lters at the recommended intervals as indicated in this system manual. When
replacing the fi lter elements, pay special attention to any cleaning instructions. Should you have any further questions please
