Maintenance 3. Insert a new filter cartridge. Use only Samsung-provided or approved filters. Maintenance 4. Turn the cartridge knob clockwise to lock into place. 5. Press and hold Filter Reset on the main panel for 3 seconds to reset the life cycle detector. The Filter Reset indicator ( ) turns off. 6. When you are done replacing the filter, open the water valve and run water through the dispenser for about 7 minutes. This is to remove impurities and air from the water line. NOTE • A newly installed filter may cause the water dispenser to spurt water briefly. This is because air has entered the waterline. • The replacement process may cause the water dispenser to drip for a short period of time. If it drips, simply wipe up any water on the floor with a dry towel. Reverse osmosis water filtration system The water pressure of the water supply system to a reverse osmosis water filtration system must be between 35 psi and 120 psi (241 kPa and 827 kPa). The water pressure of the reverse osmosis water filtration system to the refrigerator's cold water line must be at least 40 psi (276 kPa). If the water pressure is below these specifications: • Check if the sediment filter in the reverse osmosis system is blocked. Replace the filter if necessary. • Refill the water tank in the reverse osmosis system with water. • If your refrigerator has a water filter, it may further reduce the water pressure when used in conjunction with a reverse osmosis system. Remove the water filter. For more information or servicing, contact a licensed plumbing professional. 66 English Untitled-3 66 2020-04-07 PM 3:29:52
