Product Operation
Air Purification System
Many fresh foods emit ethylene gas, a naturally-occurring
compound that hastens food ripening and spoilage. If your
unit is equipped with an air purification system, the car-
tridge has been factory installed and is located on the back
wall of the refrigerator.
To turn on air purification, touch on the options screen.
WARNING
This appliance contains a UV emitter. Do not stare at
the light source.

Water Filtration System
The water filtration system supplies filtered water to the ice
maker and water dispenser (dispenser models) to produce
great-tasting water and ice.
IMPORTANT NOTE: When using the water filtration system
for the first time and after filter replacement, it is neces-
sary to clear any air from the system and allow the filter
to assist in cleaning the water lines. For non-dispenser
models, discard the first two full containers of ice. For
dispenser models, dispense several glasses of water for a
period of two minutes.
If the water filtration system will not be used, it can be
placed in water filter bypass mode by removing the filter.
WATER FILTER
The water filter is rated for 300 gallons or one year,
(1136 L)
whichever comes first. "Snooze/Refresh" appears on the
control panel when the filter needs to be replaced. Touch
"Snooze" to delay the reminder for 24 hours or until the
filter can be replaced.
To replace the water filter:
1 To access the water filter, pull out on the bottom edge
of the access door and rotate upward. Refer to the
illustration below.
2 To remove the old filter, rotate counterclockwise
one-quarter turn, then pull out. It is normal for a small
amount of water to drip when the filter is removed. It
should be wiped up with a paper towel or cloth.
3 Remove the new filter from packaging and remove the
plastic cap.
4 Insert the new filter into the manifold and turn clock-
wise.
5 Once the new filter has been installed, follow instruc-
tions on the control panel. The filter life cycle will reset
for approximately one year.
