Introduction
Thank you for your purchase of a state of the art Watts Kwik-
Change™ Zero Waste 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 water treatment system has
been designed and tested to provide you with high-quality drink-
ing 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 contami-
nants (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 technol-
ogy, and can therefore provide a higher quality drinking water than
carbon filtration systems alone .
Your system is a three stage RO which is based upon separate
treatment segments within the one complete water filtration system .
These stages are as follows:
Stage 1 – Carbon filter, recommended change 6 months.
The first 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 2 – Membrane, recommended change 2 to 5 years.
Stage-2 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 3 - Carbon post filter, recommend change 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 cannot taste it, does not mean that it is not there .
Contaminants such as Lead, Chromium and Arsenic are undetect-
able 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 recom-
mended intervals as indicated in this system manual . When replacing
the filter elements, pay special attention to any cleaning instructions .
