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