*Air delivery values are without air filter and are for dry coil. See
Table 17 for wet coil pressure drop. Deduct field-supplied air filter pres-
sure drop and wet coil pressure drop to obtain external static pressure
available for ducting.
†Unit air delivery is outside of operating range.
**For 460 v units only.

NOTES:
1. Dashed areas do not fall within approved range.
2. The above values occur with the AC/HP CFM ADJUST select jumper
set on MED.
3. Airflow can be adjusted 10% or −10% by selecting HI or LO for all
modes except FAN ONLY.

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