Abstract
A packaged terminal air conditioner (PTAC) system includes a wall sleeve in which a chassis is mounted. The wall sleeve includes a bottom configured as a drain pan to collect condensate from the chilling components of the chassis. At a side wall of the wall sleeve there is an aperture configured to allow a person to insert a treatment pellet. The treatment pellet is water soluble and contains an antimicrobial component that prevent or inhibits the growth of biological material that could obstruct the drain system of the wall sleeve and PTAC. A rotating cover is positioned at the side wall to normally cover the aperture and prevent foreign objects from entering the PTAC, but the rotating cover can be rotated so that a hole in the rotating cover aligns with the aperture, allowing insertion of the treatment pellet.
