Watts Radiant WQC4 RO Benutzerhandbuch

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. 

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 three is the heart of the reverse osmosis system, the RO membrane.  This semi-permeable membrane will  take 
out salts, minerals, metals, bacteria, virsus, 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.
