*Air delivery values are based on operating voltage of 230 v or 460 v, dry coil, without ®lter. Deduct wet coil and ®lter 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. Evaporator coil frosting may occur at air¯ows below this point.

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