Thank you for your purchase of a state of the art Watts Reverse Osmosis (RO) water treatment system. Water
quality concerns are becoming more of a focus for the public. 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
substances like clean water, but not other substances such as salts and minerals.
Reverse osmosis uses a semi permeable membrane; however, by applying pressure across the membrane, it
concentrates contaminants on one side of the membrane, producing clean water on the other. This is why RO
systems produce both clean drinking water and waste water that is flushed from the system.
Your system is a Four Stage RO which is based upon four separate treatment segments within 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 – Pre-Carbon filter, recommended change 6 months.
The second stage contains a 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 reduce salts, minerals, metals, and much more. 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- Post Carbon Filter, recommend change 12 months.
The post carbon filter is a granular activated carbon (GAC) cartridge using coconut shell carbon. This
filter provides final polishing and ensures great tasting drinking water.
System Maintenance
Just because you can not taste it, does not mean that it is not there. Contaminants such as lead, chromium, VOC’s
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 filter at the recommended intervals as indicated in this system manual.
Should you have any further questions please contact the dealer that you purchased the unit from.
With proper installation and maintenance, this system will provide you with high quality water for years to come.
All of Watts water enhancement products are rigorously tested.
NOTE: This manual is used for several variations of the same system. Your system may
vary slightly from the pictures or descriptions contained in this manual.
It is end users responsibility to ensure that this system is installed according to all
local codes and regulations.
