1,350 CFM NOMINAL AIRFLOW COOLING/1,350 CFM NOMINAL AIRFLOW HEATING*
LEGEND *Performance capacities shown in thousands of Btuh.
NOTES:
1. Interpolation is permissible; extrapolation is not.
2. All entering air conditions are 80 F db and 67 F wb in cooling, and 70 F db in heat-
ing. AHRI/ISO certified conditions are 80.6 F db and 66.2 F wb in cooling and
68 F db in heating.
3. Table does not reflect fan or pump power corrections for AHRI/ISO conditions.
4. All performance is based upon the lower voltage of dual voltage rated units.
5. Operation below 40 F EWT is based upon a 15% methanol antifreeze solution.
6. Operation below 60 F EWT requires optional insulated water/refrigerant circuit.
7. See performance correction tables for operating conditions other than those listed
above.
