Where to find the filter

  1. Turn off all power to the air handler
  2. Open the filter access panel on the cabinet (loosen the thumb screws if used)
  3. Slide the old filter out of the factory filter rails
  4. Slide in the new filter and refasten the panel keeping the washer behind each thumb screw in place
