USING YOUR REFRIGERATOR WATER FILTER It is recommended that you replace 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. 2) Replace with a new cartridge. Take the new cartridge out of it's 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. 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 of the cartridge. If you can 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 it's handle, twist the cartridge clockwise about 1/4 turn. You will hear the snap when it clicks into place. NOTE: Replacing filter causes small amount of water (around 25cc) to flow out. Please put up a cup under the hole to prevent it. 3) Flushing the water system after replacing filter. To clean the system dispense 2.5 gallons (9.46 L) of water through filter before use (dispense for approximately 5 minutes). 16
