4204490 Sub Zero Filter Cartridge Instructions:

1. Lift the top grille assembly to access the water filter cartridge. To lift the grille, pull out on the bottom edge of the grille and tilt the grille frame forward.
2.Slowly rotate the water filter cartridge one-quarter turn counterclockwise to disengage. Gently twist until the cartridge is free form the base. DO NOT PULL. There will be water in the filter cartridge, so it is normal for a small amount of water to spill out.
3. Remove the cap from the replacement water filter cartridge.
4. Line up the cartridge so that the locking tabs can be inserted into the filter head.
5. Rotate the filter cartridge into the base approximately one-quarter turn clockwise until it stops. DO NOT OVER-TIGHTEN.
6. After the new filter cartridge is installed, the first full bucket of ice produced should be discarded. This will help clean the water system and clear air from the line. Allow 24 hours before discarding the first bucket of ice.
