How To Install The MSWF Filter:
- Remove old filter cartridge by grasping and slowly rotating to the left (counterclockwise)
- Position new cartridge inside the cartridge holder and slowly rotate the cartridge to the right (clockwise) until it stops. The cartridge will rotate about 1/2 turn. Do not overtighten
- Flush 4.5 gallons through the filter before use. This will clear the system and prevent sputtering
- Press and hold reset water filter button if your fridge has one
- Replace the filter every 6 months
