Description
The OE522-XX Round Bypass Damper
Assembly, consists of a round air damper
with a bypass actuator and bypass wiring
interface card mounted in a control
enclosure.
The Bypass Damper controls duct static
pressure to insure proper system airflow.
The Bypass Damper is controlled by the
Orion HVAC Unit Controller. The Unit
Controller modulates the Bypass Damper in
response to the duct static pressure, based
on a signal received from a static pressure
sensor located in the main system ductwork.
All dampers are tested for performance in
accordance with AMCA 500D standards.
Mounting
The Round Bypass Damper Assembly
should be mounted according to standard
duct installation practices with airflow
direction as shown in the illustration above.
After installation of the Bypass Damper in
the ductwork, insulation should be applied
around any remaining un-insulated surface
on the damper inlet and outlet. The Bypass Damper should be mounted so the control enclosure is positioned to
the left or right side of the ductwork with the control enclosure in a vertical plane. Do not mount the Bypass
Damper Assembly with the control enclosure on the top or bottom of the ductwork. Adequate clearance should
be maintained between the control panel and any obstruction to allow for removal of the control panel cover and
access to the controls.
