prescribed by the Contract Documents.
Adjust patterns of adjustable outlets for proper distribution without drafts.
PROCEDURES FOR VARIABLE-AIR-VOLUME SYSTEMS
A.
Compensating for Diversity: When the total airflow of all terminal units is more than the
indicated airflow of the fan, place a selected number of terminal units at a minimum
set-point airflow with the remainder at maximum-airflow condition until the total airflow
of the terminal units equals the indicated airflow of the fan. Select the reduced-airflow
terminal units so they are distributed evenly among the branch ducts.
B.
Pressure-Independent, Variable-Air-Volume Systems: After the fan systems have
been adjusted, adjust the variable-air-volume systems as follows:
1.
2.
3.
4.

a position that simulates full-cooling load.
Measure total system airflow. Adjust to within indicated airflow.
Set terminal units at maximum airflow and adjust controller or regulator to deliver
the designed maximum airflow.
Use terminal-unit manufacturer's written
instructions to make this adjustment. When total airflow is correct, balance the
air outlets downstream from terminal units the same as described for constantvolume air systems.
Set terminal units at minimum airflow and adjust controller or regulator to deliver
the designed minimum airflow. Check air outlets for a proportional reduction in
airflow the same as described for constant-volume air systems.
