6.5.4.2.1.1 Vertical Sash Only (AI-2) Configuration
Follow the steps below to configure the controller for a
Vertical Sash
style fume hood.
Note:
Most VAV fume hoods are designed with some open area located above and below the sash to
provide a means for air to enter the fume hood from the room when the sash is in the closed position. The
open area above the sash, usually referred to as a
“restricted
upper
bypass”, allows a
ir to enter the fume
hood only when the sash is closed, or nearly closed. As the sash is raised, the upper bypass becomes
blocked limiting the amount of air that can enter from this opening. The lower bypass or airfoil slot
provides a means below the sash for air to enter the fume hood and flow over the work surface. The lower
bypass area is not affected by the sash position.
6.5.4.2.1.2 Horizontal Sash Only (AI-3) Configuration
Refer to the Horizontal Sash Sensor Installation Guide for proper installation of the Accutrol
