PRO 48 Use & Care 11 subzero.com Water Filtration System WATER FILTER CARTRIDGE REPLACEMENT 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. Refer to the illustration below. 2) Slowly rotate the water filter cartridge one-quarter turn counterclockwise to disengage. Gently twist until the cartridge is free from 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. Refer to the illustration below. 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 overtighten. 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. WATER FILTER BYPASS MODE If you choose not to use the water filtration system, the system can be placed in water filter bypass mode by removing the water filter cartridge. In this mode, the water supplied to the ice maker will not be filtered and the water filter monitor will be deactivated. The water filtration system automatically goes into bypass mode when the filter cartridge is removed. Once a filter cartridge is reinstalled, the water filtration system will be activated and the water filter monitor function will resume. IMPORTANT NOTE: If a reverse osmosis system is used, the water filter cartridge must be removed to put the water filtration system into bypass mode. WATER FILTER Lift grille assembly.
