How do I change the water filter on my Samsung refrigerator?

Shut off the water supply, then turn the water filter about 1/4 turn counter-clockwise and pull it out of the filter case. Insert the new Samsung brand filter, push it in, and turn it clockwise until it locks. After installing the new filter, press and hold the Crushed Ice button for 3 seconds to reset the filter indicator from red to off. (Page 22)
