For other airflow conditions, see heating capacity correction factor (Table PD-39).
Net heating capacity and power input includes indoor fan heat at ARI esp. To obtain net heating at other conditions, subtract fan heat at this
condition and add fan heat at new condition.
Note:
1. Integrated heating capacities and powers include the effects of defrost in the frost region. All heating capacities and power (kw) are at 70%
OD relative humidity and demand defrost cycle.
