How To Install The GSWF Filter:
- Open cartridge cover by pushing in where indicated
- Remove old filter cartridge by 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 1/4 turn. When installed correctly, the grip blade on the end of the cartridge should be positioned vertically for top-freezer models and horizontally for bottom freezer models. Do not overtighten
- Close cartridge cover
- Reset filter change indicator if your refrigerator has one
- Flush 1.5 gallons (approximately 3 minutes) through the filter before use. This will clear the system and prevent sputtering
