Access/Return Air Panels are insulated for sound reduction with tamper-proof screws. The Louvered Access/Return Air Panel (AVLWP01A-L) includes a left hinged access door giving you easy access to the filter with the return air grille low on the door. A 25" x 20" field supplied filter is mounted on the interior side of the door.
Access/Return Air Panels are available with the hinge on the left or right side. It is recommended that the hinge be on the left side for 24,000 BTU units with the return air openings low on the door. The kit contains a hinge bracket for mounting the door with the return air openings high or low on the door for optimal sound attenuation.
The door is 58"h x 29"w with cutouts of 55.75"h x 27"w.
