Flush 1 gallon of water through the filter, onecup or glass at a time. (Flush approximately 6minutes.) This will clean the water supply systemand remove air from the lines.- Additional flushing may be required in somehouseholds.3. Open the refrigerator door and make sure thereare no water leaks coming from the water filter.Reverse Osmosis Water SupplyIMPORTANT : The pressure of the water supplycoming out of a reverse osmosis system going tothe water inlet valve of the refrigerator needs to bebetween 35 and 120 psi (241 and 827 kPa).If a reverse osmosis water filtration system isconnected to your cold water supply, the waterpressure to the reverse osmosis system needs to be aminimum of 40 to 60 psi (276 to 414 kPa.)If the water pressure to the reverse osmosis system isless than 40 to 60 psi (276 to 414 kPa):• Check to see whether the sediment filter in thereverse osmosis system is blocked. Replace thefilter if necessary.• Allow the storage tank on the reverse osmosissystem to refill after heavy usage.• If your refrigerator has a water filter, it mayfurther reduce the water pressure when usedin conjunction with a reverse osmosis system.Remove the water filter.If you have questions about your water pressure, call alicensed, qualified plumber.Ordering replacement filtersTo order more water filter cartridges, contact yourauthorized Samsung dealer.
