Before Starting, obtain
Pre - balance Equipment and System Check
Equipment Check
1.Check fan housings, coils, louvers, etc., to ensure they are clean and free of foreign material.
2.Check filters to ensure that they are clean and in place.
3.Check adjustment of vibration eliminators.
4.Examine drives for proper belt tension and alignment.
5.Check fan and motor lubrication.
6.Check fan overload proctors or heaters for proper size – check motor amperage to guard against overload.
7.Check automatic dampers for proper operation and position.
8.Check fan for proper rotation.

System Check
1.Check for installation of all required balance dampers.
2.Turn off the air handler unit (AHU).
3.Set all system dampers in their open position. This includes all volume dampers, fire dampers, outlet dampers, etc.
4.Turn on the AHU. (Caution: Check fan amperages, in some cases the AHU motor may be overloaded when the system is turned on when all system dampers are opened).
5.Check for air leaks at the fan and the system ductwork.
6.Position all doors and windows to their normal position.
7.Check air temperature to ensure required air temperature delivery.
Air Balancing
Air Handling Equipment Balance
1.Check motor amperage and voltage to ensure motor is not being overloaded. (See form Vibration Test Data Air Handling Unit (AHU 1)
2.Set minimum outdoor air quality using the temperature ratio method.
Tm = (% O.A.)(To) + (% R.A.)(Tr)
%O.A. = 100
%R.A. = 100
Xo = Percent outdoor air
Xr = Percent return air
To = Outside air temperature
Tr = Return air temperature
Tm = Mixed air temperature

3.Determine the volume of the air being delivered by the fan. Adjust the fan speed to increase or decrease the flow if required. If the speed is increased, ensure the motor is not overloaded. Check total flow with the dampers set to their minimum outside air and again for 100 percent outside air; variation should be within 10 percent.
4.Check fan motor speed, operating amperage and voltage. Calculate break horsepower.
5.Take fan static pressure readings and static pressure across the fan system components; i.e., filters, coils, etc.
System Balancing
1.Using the duct velocity traverse method, adjust the volume dampers to deliver the design airflow in each main, zone, and branch duct. (See the following forms: Air Cooled Condensing Unit
2.Adjust the individual supply outlets both for air volume and distribution pattern. Follow the manufactures’ recommended procedure, using the proper factor. Use the proportional (ratio) method or other appropriate systematic procedure for outlet balancing. Compare the outlet total flow to the duct traverse previously made; variation should be within 10 percent.
3.Using the same basic procedures for the supply side, balance the return and exhaust systems.
4.Recheck speed, amperage and pressure readings at the fan.
5.Submit Reports. (Air Handler Test and Balance Report
