- How to replace the air purification cartridge
Air purification filters are ready to be replaced whenever the indicator light begins to flash.
- A steady indicator light is normal.
- There is no harm to the Sub-Zero unit if the air filter is not replaced or not used.
- Refer to How to Purchase Sub-Zero Air Filters for part number and purchasing information.
For other product lines and general air filter information, refer to Sub-Zero Air Purification Filter Replacement.
- Find the air filter access door cover on the inside back wall of the refrigerator, upper right-hand side. The door is usually between the top two shelves depending on shelf placement. It may be necessary to remove a shelf if it is positioned in front of the access door.
- To access the air purification cartridge, hold the outside cover from the bottom and rotate upward. The cartridge will be inside as shown.
- Hold the black cover from the top and rotate downward. The cartridge will pop out and can be removed.
- Remove the new cartridge from packaging and insert with connector pointing downward.
- The Sub-Zero logo does not have to be facing out. The cartridge may be installed with the logo facing inside the unit.
- Once in position, close the black cover. Then rotate the outside cover downward until it closes against the back wall.
- Once the cartridge has been replaced, touch and hold PURE AIR on the control panel for five seconds to reset.
- The indicator will appear in the control panel display but not flash.
- The timer is reset.
If the filter light does not clear:
- Make sure the pad of the fingertip is used to press the button to reset the timer.
- If the cartridge is replaced before the icon starts to flash, the PURE AIR key still must be held for five seconds to reset the timer.
- If the light continues to flash, contact Factory Certified Service to schedule an appointment for repair.
