Cap. — Heating Capacity (1000 Btuh) (Includes Indoor-Fan Motor Heat)
db — Dry Bulb
kW — Total Power Input (Includes Compressor Motor Power Input, Outdoor-
Fan Motor Input, and Indoor-Fan Motor Input)
rh — Relative Humidity
NOTES:
1. indicates integrated ratings.
2. Integrated capacity is maximum (instantaneous) capacity less the effect of frost
on the outdoor coil and the heat required to defrost it.
