20_ operatingRemoving any residual matter insidethe water supply line after installingthe water filter.1. Turn ON the main water supplyand supply water from watersupply line.2. Run water through thedispenser until the water runsclear (approx. 6 to 7 minutes).This will clean the water supply system andremove air from the lines.3. Additional flushing may be required in somehouseholds.4. Open the Refrigerator door and make sure thereare no water leaks coming from the water filter.Be sure to flush the dispenser thoroughly,otherwise water may drip from the dispenser.This means that there is still air in the line.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 bea minimum of 40 to 60 psi (276 to 414 kPa.)If the water pressure to the reverse osmosis systemis less 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, calla licensed, qualified plumber.
