HEATING & COOLING
The 38YKB Outdoor Sections of
Split-System Heat Pumps are
designed for quiet, reliable heating
during the winter and cooling during
the summer. 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 cycle, remove indoor heat
and excess humidity during the
cooling season. All models are listed
with ARI, UL, CSA and CEC. All
models are offered in 208/230v.
FEATURES/BENEFITS
Compressor
— All models feature
the scroll compressor with the
exception of the 018-31 which has a
reciprocating compressor. Each
compressor is mounted on rubber
isolators for additional sound
reduction. The scroll compressor will
start under most system loads, thus
eliminating the need for start
assistance components. 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-Reliability Components
— Includes a suction accumulator
that keeps liquid refrigerant from
reaching the compressor; a discharge
thermostat on 024 through 042 sizes
to protect the scroll compressor
from excessive internal discharge
temperatures under extreme
operating conditions, i.e. loss of
