Deduct wet coil, filter,and electric heater pressure drops to obtain external static pressureavailable for ducting.NOTES:1. Do not operate the unit at a cooling airflow that is less than350 cfm for each 12,000 Btuh of rated cooling capacity. Indoor coilfrosting may occur at airflows below this point.2. Dashes indicate portions of table that are beyond the blower mo-tor capacity or are not recommended.23
