1 Unless otherwise noted, vertical air handling units are UL listed up to 0.5 in. wg total static pressure, including coil, case, duct work pressure drop, air filter, and largest kW size heater.
Internal static pressure includes coil and case only.
* Airflow rate (CFM) decreases by 3% per 0.1 in. wg.
Factory default status is 0.3 in wg.
Factory default is high static pressure.
• If the ESP is set incorrectly, the air conditioning may malfunction.
• To get the desired air flow and external static pressure combination, use the setting value from the table. Using a setting value other than the values
listed in the table will not provide the desired combination.
