38AYC (60 Hz)
11 SEER Heat Pump
Sizes 018 thru 060
Copyright 2004 Carrier Corporation Form 38AYC-5PD
The 38AYC Split-System Heat Pumps
are designed for quiet, reliable heating
and cooling. With SEER ratings from
11.0 to 12.5 and HSPF ratings from 7.0
to 8.3, these heat pump systems provide
efficient operation. These units provide
heat during the winter months by
transferring heat from the outdoors.
They then reverse this process during
the summer months to reliably provide
cooling and dehumidification. All
models are listed with UL, (U.S. and
Canada), CEC and ARI.
AVAILABLE OPTIONS
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 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,
all 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
refrigerant that reaches the compressor,
a loss of charge switch, and an internal
pressure relief valve (except 018–024
sizes) for high-pressure protection.
