indicated airflow of the fan, place a selected number of terminal units at a maximum set-point

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. Variable-Air-Volume Systems: After the fan systems have been adjusted, adjust the variable-

air-volume systems as follows:

1. Set outside-air dampers at a position that simulates full-load.

2. Select the terminal unit that is most critical to the supply-fan airflow and static pressure.

Measure static pressure. Adjust system static pressure so the entering static pressure for

the critical terminal unit is not less than the sum of minimum inlet static pressure plus the

static pressure needed to overcome terminal-unit discharge system losses.

3. Measure total system airflow. Adjust to within indicated airflow.

4. Set terminal units at maximum airflow and adjust controller or regulator to deliver the

designed maximum airflow. When total airflow is correct, balance the air outlets

downstream from terminal units as described for constant-volume air systems.

5. 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 as

described for constant-volume air systems.

a. If air outlets are out of balance at minimum airflow, report the condition but leave

outlets balanced for maximum airflow.

6. Remeasure the return airflow to the fan while operating at maximum return airflow and

minimum outside airflow. Adjust the fan and balance the return-air ducts and inlets as

described for constant-volume air systems.

7. Measure static pressure at the most critical terminal unit and adjust the static-pressure

controller at the main supply-air sensing station to ensure that adequate static pressure is

maintained at the most critical unit.

8. Record the final fan performance data.

3.7 GENERAL PROCEDURES FOR HYDRONIC SYSTEMS

A. Prepare test reports with pertinent design data and number in sequence starting at pump to end

of system. Check the sum of branch-circuit flows against approved pump flow rate. Correct

variations that exceed plus or minus 5 percent.

C. Prepare hydronic systems for testing and balancing according to the following, in addition to the

general preparation procedures specified above:

1. Open all manual valves for maximum flow.

2. Check flow-control valves for specified sequence of operation and set at indicated flow.

3. Set differential-pressure control valves at the specified differential pressure. Do not set at

fully closed position when pump is positive-displacement type unless several terminal

valves are kept open.

4. Set system controls so automatic valves are wide open to heat exchangers.

5. Check air vents for a forceful liquid flow exiting from vents when manually operated.

D. Check the operation of limiting controllers (i.e., high- and low-temperature controllers).

E. Check free travel and proper operation of control devices such as damper and valve operators.

F. Check the sequence of operation of control devices. Note air pressures and device positions and

correlate with airflow and water flow measurements. Note the speed of response to input

changes.

G. Check the interaction of electrically operated switch transducers.

H. Check the interaction of interlock and lockout systems.

I. Check main control supply-air pressure and observe compressor and dryer operations.
