3. Lift open the vented air filter door. On some models, there are
notches behind the door.
Models with notches:
■ With the indicator screen facing outward, slide the
indicator down into the notches.
NOTE: The indicator will not easily slide into the notches
if the bubble has not been popped.
■ Close the air filter door, and check that the indicator is
visible through the window in the door.
Models without notches:
■ Place the indicator somewhere it is easily visible - either
inside the refrigerator, or elsewhere in your kitchen or
home.
Replacing the Air Filter
The disposable air filter should be replaced every 6 months, when
the status indicator has completely changed from white to red.
To order a replacement air filter, contact us. See “Accessories” in
the User Guide, Use and Care Guide or User Instructions for
information on ordering.
1. Remove the used air filter by squeezing in on the side tabs.
2. Remove the used status indicator.
3. Install the new air filter and filter status indicator using the
instructions in the previous sections.
Install Produce Preserver
(on some models)
The produce preserver absorbs ethylene, to slow the ripening
process of many produce items. As a result, certain produce
items will stay fresh longer.
Ethylene production and sensitivity varies depending on the type
of fruit or vegetable. To preserve freshness, it is best to separate
produce with sensitivity to ethylene from fruits that produce
moderate to high amounts of ethylene.
