Step 3. Using the fan table provided below, select the corresponding fan %PWM by plotting the external static pressure
requirement (duct static pressure) and nominal airflow requirement of the unit. (Data may need to be calculated
to get the desired value).
Step 4. Using slotted screwdriver adjust CPI3-2 board 0-99% PWM output by rotating the potentiometer to obtain the
desired %PWM. Clockwise to increase the %PWM and counter-clockwise to lower the %PWM.
