Prior to unit installation, be sure that the exterior wall openings and louvers, as applicable,
are ready and in accordance with the job plans.
Vertical Floor Models AVS, AVV, AVB, AVR are typically installed in front of a wall
opening containing a properly sized louver that is designed to let in outside air while
preventing water (such as driving rain) from getting past the louver and into the unit itself.
A weather-tight seal keeps unwanted air and moisture from entering the occupied space.
See Figures 1 through 18, and table 1 for various louver details.
