*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.

²Size 048 is 460 v.

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.

*Air delivery values are for dry coil at 230 v. Air¯ow is independent of external static pressure within 65% of table values up to 0.8 in. wg.

NOTE: 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 icing may occur at air¯ows below this point. Water blow-off may occur at air¯ows above 450 cfm per 12,000 Btuh of rated cooling capacity.
