How do I install a new water filter cartridge in the LSC27931**?

Remove the old cartridge by turning it to the left, then insert the new cartridge vertically and press it firmly into place until it clicks. Turn the cartridge to the right approximately 1/4 turn until you hear a click confirming it is locked in place. After installation, flush 2.5 gallons (9.46 litres) of water through the filter before use, which takes approximately 5 minutes. (Page 16)
