               speed. Comply with requirements in Division 23 Sections for air-handling units for
               adjustment of fans, belts, and pulley sizes to achieve indicated air-handling-unit
               performance.
         7.    Do not make fan-speed adjustments that result in motor overload. Consult equipment
               manufacturers about fan-speed safety factors. Modulate dampers and measure fan-
               motor amperage to ensure that no overload will occur. Measure amperage in full-cooling,
               full-heating, economizer, and any other operating mode to determine the maximum
               required brake horsepower.

   B.    Adjust volume dampers for main duct, submain ducts, and major branch ducts to indicated
         airflows within specified tolerances.

               a.     Where sufficient space in submain and branch ducts is unavailable for Pitot-tube
                      traverse measurements, measure airflow at terminal outlets and inlets and
                      calculate the total airflow for that zone.

         2.    Measure static pressure at a point downstream from the balancing damper, and adjust
               volume dampers until the proper static pressure is achieved.
         3.    Remeasure each submain and branch duct after all have been adjusted. Continue to
               adjust submain and branch ducts to indicated airflows within specified tolerances.

   C.    Measure air outlets and inlets without making adjustments.

         1.    Measure terminal outlets using a direct-reading hood or outlet manufacturer's written
               instructions and calculating factors.

   D.    Adjust air outlets and inlets for each space to indicated airflows within specified tolerances of
         indicated values. Make adjustments using branch volume dampers rather than extractors and
         the dampers at air terminals.

3.06     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 the approved pump flow rate.
         Correct variations that exceed plus or minus 5 percent.

   B.    Prepare schematic diagrams of systems' "as-built" piping layouts.

   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 liquid level in expansion tank.
         3.    Check makeup water-station pressure gage for adequate pressure for highest vent.
         4.    Check flow-control valves for specified sequence of operation, and set at indicated flow.
         5.    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.
         6.    Set system controls so automatic valves are wide open to heat exchangers.
         7.    Check pump-motor load. If motor is overloaded, throttle main flow-balancing device so
               motor nameplate rating is not exceeded.
         8.    Check air vents for a forceful liquid flow exiting from vents when manually operated.


3.07     PROCEDURES FOR CONSTANT-FLOW HYDRONIC SYSTEMS

   A.    Measure water flow at pumps. Use the following procedures except for positive-displacement
         pumps:

         1.    Verify impeller size by operating the pump with the discharge valve closed. Read
               pressure differential across the pump. Convert pressure to head and correct for
               differences in gage heights. Note the point on manufacturer's pump curve at zero flow
               and verify that the pump has the intended impeller size.

               a.     If impeller sizes must be adjusted to achieve pump performance, obtain approval
                      from Architect and comply with requirements in Division 23 Section "Hydronic
                      Pumps."

         2.    Check system resistance. With all valves open, read pressure differential across the
               pump and mark pump manufacturer's head-capacity curve. Adjust pump discharge valve
               until indicated water flow is achieved.

               a.     Monitor motor performance during procedures and do not operate motors in
                      overload conditions.

         3.    Verify pump-motor brake horsepower. Calculate the intended brake horsepower for the
               system based on pump manufacturer's performance data. Compare calculated brake
               horsepower with nameplate data on the pump motor. Report conditions where actual
               amperage exceeds motor nameplate amperage.
         4.    Report flow rates that are not within plus or minus 10 percent of design.

   B.    Measure flow at all automatic flow control valves to verify that valves are functioning as
         designed.

   C.    Measure flow at all pressure-independent characterized control valves, with valves in fully open
         position, to verify that valves are functioning as designed.

   D.    Set calibrated balancing valves, if installed, at calculated presettings.

   E.    Measure flow at all stations and adjust, where necessary, to obtain first balance.

         1.     System components that have Cv rating or an accurately cataloged flow-pressure-drop
                relationship may be used as a flow-indicating device.

   F.    Measure flow at main balancing station and set main balancing device to achieve flow that is 5
         percent greater than indicated flow.

   G.    Adjust balancing stations to within specified tolerances of indicated flow rate as follows:

         1.     Determine the balancing station with the highest percentage over indicated flow.
         2.     Adjust each station in turn, beginning with the station with the highest percentage over
                indicated flow and proceeding to the station with the lowest percentage over indicated
                flow.
         3.     Record settings and mark balancing devices.

   H.    Measure pump flow rate and make final measurements of pump amperage, voltage, rpm, pump
         heads, and systems' pressures and temperatures including outdoor-air temperature.

   I.    Measure the differential-pressure-control-valve settings existing at the conclusion of balancing.
