Example :
DS-150, 460/3/60, with 13,500 CFM supply air at 2.0"
ESP, 3000 CFM minimum outdoor air with Smart Saver
Heat Recovery coils and Purge fan.
Step #1 :
Select supply motor horsepower from page 10 = 15 HP

Step #2 :
Select exhaust fan #1 (EF#1) horsepower from
page 10 = 3000 CFM OA + 10% = 3300 CFM EA = 3 HP
