replacement
We recommend replacing the filter when the
water filter indicator light turns on or your water
dispenser or ice maker decreases noticeably.
After changing the water filter cartridge, reset the
water filter status display and indicator light by
pressing and holding the BUTTON for 3 seconds.
1) Remove the old cartridge.
Rotate the knob of the cartridge counter clockwise.
When the cartridge is removed, you will feel it click
out of place.
Pull out the cartridge.
NOTE
Replacing filter causes small amount of water (around 1 oz or 25 cc) to flow out.

Please put up a cup under the hole to prevent it.
2) Replace with a new cartridge.
Take the new cartridge out of its packaging and remove
protective cover from the o-rings. With cartridge knob in
the vertical position, push the new filter cartridge into
the cover until it stops.
If you can't turn the filter from side to side, it isn't fully
inserted. Push it in firmly and twist it into place. You will
hear the snap when it clicks into place. Using its handle,
twist the cartridge clockwise about
the snap when it clicks into place.
3) Flushing the Water System After Replacing Filter.
Dispense water through the water dispenser for 3
minutes to purge the system.
