HEATING & COOLING
The 38YCA and 38YCN Outdoor
Sections of Split-System Heat Pumps
are designed for quiet, reliable heating
during the winter and cooling during the
summer. With a SEER up to 10.5 and
HSPF up to 7.5, these heat pump
systems provide economy of operation
through energy conservation when used
with components designated by
manufacturer. 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, and ARI.
FEATURES/BENEFITS
Electrical Range — All units are
offered in single phase 208–230v. The
38YCA 030 through 060 models are
offered in 208/230v 3 phase and
38YCA 036 through 060 are offered in
460v 3 phase.
Size Range — The 38YCA is available
in 7 nominal sizes from 018 through
060 to meet the needs for residential
and light commercial applications. The
38YCN is available in 5 nominal sizes
from 024 through 048 to meet the
needs of the manufactured housing
market.
Compressor — Designed specifically
for heat pump duty, with energy
efficiency during heating and cooling
operation. Each compressor is
hermetically sealed against
contamination to assure long life and
dependable performance, internally
sprung (units with reciprocating
compressor) and externally mounted on
rubber isolators for quiet operation.
Continuous compressor 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.) For compressor usage, see
Compressor data table.
