1) Lift the grille assembly to access the water
filter. To lift the grille, pull out on the
bottom edge of the grille and tilt the grille
frame forward. Refer to the grille access
illustration below.
2) Slowly rotate the old filter cartridge 1/4 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 water filter
illustration below.
3) Remove the new filter cartridge from its
packaging and carefully remove the cap.
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
about 1/4 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.

If you choose not to use the water filtration
system, the system can be placed in water
filter bypass mode. In this mode, the water
supplied to the ice maker will not be filtered
and the electronically controlled 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 you are using a reverse
osmosis system, the water filter cartridge must
be removed to put the water filtration system
into bypass mode.
