SECTION 12: DAMPERS

12.1 Discharge Damper
Discharge dampers are shipped loose. Discharge dampers are designed to be mounted downstream of the
air handler in ductwork. A qualified contractor/installer must make appropriate allowances for duct
connections.
To install the discharge damper on an interior wall, drill holes every 8" (20.5 cm) in the flanges on all four
sides of the discharge damper to accommodate lag bolts (provided by others).
Discharge dampers are not recommended to be mounted directly to the air handler.

12.2 Inlet Damper
Inlet dampers are factory mounted to the inlet of the air handler (covering the inlet opening). The inlet
damper has four outward-turned flanges. Based on air handler style, damper may include upper and lower
damper.
