NOTES:
1. Factory sheave settings are shown in bold type. 2. Do not set motor sheave below minimum turns open shown. 3. Re-adjustment of sheave required to achieve rated airflow at ARI minimum External Static Pressure 4. Drive data shown is for horizontal airflow with dry coil. Add component resistance (below) to duct resistance to determine
total External Static Pressure.
