*Air delivery values are based on operating voltage of 230 v or 460 v, dry coil, without filter. De-
duct wet coil and filter pressure drops to obtain external static pressure available for ducting.
NOTES:
1. Do not operate the unit at a cooling airflow that is less than 350 cfm for each 12,000 Btuh of
rated cooling capacity. Evaporator coil frosting may occur at airflows below this point.
2. Dashes indicate portions of table that are beyond the blower motor capacity or are not
recommended.
