A:Answer To replace the charcoal filter;
Remove 2 screws on the vent grille, slide the vent grille to the
left, tilt it forward, lift it out, and remove the filter. To reinstall,
place the filter into its 2-hook area with the wire mesh side to
the front. Replace the vent grille by inserting the 3 bottom latch
hooks of the vent grille into the front holes, tilt the vent grille
backwards, slide it to the right, and secure with screws.
