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 fl ushed from the system.
Your system is a Four Stage RO which is based upon four separate treatment segments within one complete water fi ltration
system. These stages are as follows:
Stage 1 – 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 – Pre-Carbon fi lter, recommended change 6 months.
The second stage contains a 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 1-2 years.
Stage three is the heart of the reverse osmosis system, the RO membrane. This semi-permeable membrane will
take out salts, minerals, metals, bacteria, viruses, cysts, 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 fi lter is a granular activated carbon (GAC) cartridge using coconut shell carbon. This fi lter
provides
fi nal polishing and assures good 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 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 lter 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.
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.
