AIR FLOW BALANCING

* Fantech's superior design and use of EBM motors results in a steep fan curve that

usually does not require balancing. Commissioning the system after installation is

recommended which include confirming the proper operation of the system and how

it interacts with other components within the home.

AIRFLOW STATION (GRID) METHOD

1 For this flow measuring station, cut the duct

and place the flow measuring station between

each section of duct. Make sure that the flow

measuring station's air direction arrow points

in the direction of the airflow. Secure the flow

measuring station with duct tape.

2 Before taking the reading, make sure that the

magnehelic gauge is level and at 0. Refer to

the flow measuring station's chart to

determine your unit's airflow velocity.

• To avoid airflow

turbulence and incorrect

readings, the airflow

3 Adjust the "Supply Air Out" damper until you

reach the desired velocity. Follow the previous

steps to adjust the "Exhaust Air Out" damper,

if needed.
