In general, you should change the water filter every six to nine months to ensure
highest possible water quality. The Filter Status light on the dispenser control
panel (see page 20) prompts you to replace the filter after 400 gallons of water has
flowed through the system.
If your refrigerator has not been used for a period of time (during moving for
example), change the filter before reinstalling the refrigerator.
