9. 18 WHAT YOUR REVERSE OSMOSIS SYSTEM WILL DO Your Reverse Osmosis RO Drinking Water System is a water treatment unit It uses household water pressure to reverse a natural physical process called osmosis Water under pressure is forced through a semi permeable membrane where minerals and im purities are filtered out Clean drinking water goes to the faucet or storage while minerals and impurities are sentto the drain with RO waste water The miner als and impurities are measured in water as total dis solved solids TDS The system includes replaceable pre and postfilter sediment carbon cartridges The prefilter removes sand silt dirt rust particles other sediments and chlorine from the water supply before it can enter the RO membrane The postfilter removes any tastes and or odors that may remain in the water after passing through the RO membrane and just before going to the RO faucet To prevent water waste an automatic shutoff valve closes when the RO faucet is closed and the storage tank is full Your reverse osmosis system gives you a continuous supply of sparkling clear delicious water for drink ing cooking and other uses Foods will look and taste better too Having high quality RO product wa ter at your fingertips eliminates the need to buy bottled water The storage tank holds over 2 gallons of RO product water for your needs BEFORE YOU BEGIN TO INSTALL THE RO SYSTEM FOR OPTIMUM PERFORMANCE Y
