Cap — Heating Capacity (1000 Btuh) (includes indoor-fan motor heat)
kW — Total Power Input (includes compressor motor power input, outdoor-
fan motor power input, and indoor-fan motor power input)
*Refer to Systems Index Table on page 26.
†Integrated Rating.
NOTE: Integrated capacity is maximum (instantaneous) capacity less the effect of frost on the
outdoor coil and the heat required to defrost it.
