Components
Economizer and Exhaust Air Damper
Adjustment
Exhaust Air Dampers
Verify that the exhaust dampers (if equipped) close tightly
when the unit is off. Adjust the damper linkage as
necessary to ensure proper closure. An access panel is
provided under each damper assembly.
Outside Air and Return Air Damper
Operation
The outside air and return air damper linkage is accessible
from the filter section of the unit. The damper linkage
connecting the outside air dampers to the return air
dampers is preset from the factory in the number 1
position. Refer to Figure 93, p. 139 for the appropriate
linkage position for the unit and operating airflow (CFM).
