System Maintenance
Just because you cannot taste it, does not mean that it is not there .
Contaminants such as lead, chromium and arsenic (to name a few)
are undetectable to the taste . Additionally, over time if you do not
replace the filter element, other bad tastes and odors will be appar-
ent in your drinking water .
This is why it is important to change out your filter at the recom-
mended intervals as indicated in this system manual . When replacing
the filter elements, pay special attention to any cleaning instructions .

Introduction
Thank you for your purchase of a state-of-the-art Watts Reverse
Osmosis (RO) water treatment system. Water quality concerns
are quickly becoming more of a focus for the public . Lately 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 in your area such as high levels of lead and
copper . This Watts water treatment system has been designed and
tested to provide you with high-quality 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 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 waste 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 5-stage RO which is based upon five separate
treatment segments within the one complete water filtration system .
These stages are as follows:
Stage 1 – Sediment Filter, recommended change 6 months.
(See Page 9).
The first stage of your RO system is a 5-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 Filters, recommended change 6 months.
and 3 (See Page 9).
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 4 is the heart of the reverse osmosis system, the
RO Membrane . This semi-permeable membrane will ef-
fectively take out TDS, sodium and heavy metals such as
arsenic, copper, and lead, as well as cysts, such as giardia
and cryptosporidium . Because the process of making
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 Inline Granular Activated Carbon
(GAC) Filter . This filter is used after the water storage tank
and is used as a final polishing filter .
