1. Side panel louvers are adjusted by a push-pull movement of louver handle (1). When louver handle
is pushed in, pivot bar (2) turns clockwise to open louvers of right-hand louver panel (3) and close
louvers of left-hand louver panel (4). Pulling on louver handle has opposite effect.
2. There is no adjustment within the linkage itself. Bent or distorted louver handle (1), pivot bar
(2), or louver linkage (5) can cause binding and improper louver action. Distorted parts must be
straightened or replaced to restore proper adjustment.
