External Static Pressure Setting Values - LG LV240HV4 Installation Manual

ELECTRICAL SYSTEM INSTALLATION

External Static Pressure Setting Values

Indoor Unit Static Pressure Setting
After the system is installed, use the wired controller to enter the desired static pressure setting values for high, medi-
um,and low fan speeds. Refer to the manual for your system's wired controller.

Unless otherwise noted, vertical-horizontal air handing 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.
*
• If the external static pressure is set incorrectly, the air conditioning system 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.
• Factory default is 0.3 in. wg.
• Factory default is high static pressure.
