*Air delivery values are based on operating voltage of 230 v or 460 v, dry coil, without ®lter or electric heater. Deduct wet coil, ®lter, and electric heater pressure drops to obtain external static pressure available for ducting.

NOTES:

1.Do not operate the unit at a cooling air¯ow that is less than 350 cfm for each 12,000 Btuh of rated cooling capacity. Evapo- rator coil frosting may occur at air¯ows below this point.

2.Dashes indicate portions of table that are beyond the blower mo- tor capacity or are not recommended.
