The front doors come with pre-installed air filters. If air filters need replacement, follow this procedure.
Step 1 Remove existing door filter and side brush filters as follows:
a) Remove the front door.
b) Remove the side brush filters by unscrewing the captive screws at the top of each brush filter.
c) Pull the foam air filter directly away from the door to clear of the snap-top alignment pins (two on the top, two on
the side and two on the bottom of the door).
Step 2 Install the new door filter as follows:
a) Align the 4 alignment holes on to the filter to the 4 alignment studs on the door.

b) Press the filter onto the alignment studs.
c) Install the side brush filters and use 2 screws to secure the filter to the door.
