38AYC (60 Hz)
Heat Pump
Sizes 018 thru 060
The 38AYC Split-System Heat
Pumps are designed for quiet, reliable
heating during the winter and cooling
during the summer. With SEER ratings
from 11.0 to 13.5 and HSPF ratings
from 7.2 to 8.3, these heat pump
systems provide economy of operation
through energy conservation. They
recover heat for indoor comfort from
outdoor air during the heating season
and, by automatically reversing the
refrigerant system, remove indoor heat
and excess humidity during the cooling
season. All models are listed with UL,
c-UL, CEC, CSA-EEV, and ARI.
FEATURES/BENEFITS
Electrical Range — All units are
offered in single phase 208–230v.
Size Range — 38AYC is available in 7
nominal sizes from 018 through 060 to
meet the needs of residential and light
commercial applications.
Compressor — This unit features a
scroll compressor (except 018 size)
which is significantly more efficient
than conventional compressors. Its
simple design offers improved
reliability. Each compressor is
mounted on rubber isolators for
additional sound reduction. For
improved serviceability, the 018
through 042 models are equipped with
a compressor terminal plug.
Continuous operation is approved
down to –30 F (–34.4 C) in the
heating mode and down to 55 F
(12.8 C) in the cooling mode. (See
heating and cooling performance
tables.)
Built-in-Reliable Components —
Includes a suction-tube accumulator
that reduces the amount of liquid
Form 38AYC-1PD
