On select models, you may notice a small tab identified with Open / Fresh Air / Closed.

This fresh air vent allows the air conditioner to:

1. Recirculate inside air - Vent Closed

2. Draw fresh air into the room - Fresh Air

3. Expel indoor air outside - Vent Open.

Note: When in the cool mode fresh air venting or exhaust venting will affect cooling and decrease performance.
