size. 30 second cycling time.
ELECTRICAL RATINGS: Power Supply: 24 Vac, 50/60 Hz.
HUMIDIFIER: For humidification, use evaporative type
or return air type humidifiers. Do not use spray or
atomization type humidifiers installed in the furnace
plenum or air supply duct.

MOUNTING: Install into a 3-in. [76 mm] opening in the air
duct and secure using sheet metal screws provided.
WIRING CONNECTIONS: Screw terminals on electronic
actuator face plate. Actuator cover protects terminals
after installation.
BLADES: Heavy gauge extruded aluminum. Aerodynamic
blades reduce air turbulence, noise, vortexing, and loss
of air velocity.
DIMENSIONS:
AOBD: See Fig. 11.
AOBD-BM: See Fig. 12.
ACCESSORIES: Set of Damper Mounting Tracks (Model
SDMT): Two U channel mounting tracks 12 in. [305 mm]
long used to hold large size dampers, multiple dampers,
and undersized dampers in proper alignment.
