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
throughenergy conservation when used
with components designated by
manufacturer. They recover heat for
indoor comfort from outdoor air during
theheatingseasonand,byautomatically
reversingtherefrigerantsystem,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

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.

Built-in-Reliability
Components
— Includes a suction-tube
accumulator that reduces the amount of
liquid refrigerant that reaches the
compressor; a low-pressure switch to
stop the compressor if refrigerant charge
is lost; a crankcase heater on units with
reciprocating compressor and all
3-phase units to keep compressor oil
warm and free of refrigerant for
maximum lubricity; an internal
compressor relief valve for high-pressure
protection.
Discharge Muffler — Minimizes
low frequency sound and pressure
pulsation generated by compressor
discharge gas.
Defrost Control Board — Incorporates
a defrost relay, defrost timer, and
low-voltage terminations. The defrost
control is a time and temperature
initiation/termination control which
includes 3 field-selectable time periods of
30, 50, and 90 minutes. The control
includes built-in 5-minute compressor
delay for units equipped with scroll
compressors (see Compressor data table).
Weather-Protective Cabinet — Steel is
protected with a heavy coating
commonly called “galvanizing,” and
coated with a layer of zinc phosphate. A
coat of modified polyester powder
coating is then applied and baked-on,
providing each unit with a hard, smooth
finish that will last for many years.
All screws on cabinet exterior are coated
for a long-lasting rust-resistant, quality
appearance.
Unit Design — All units are equipped
with totally enclosed fan motors for
greater reliability under rain and snow
conditions. The large, wraparound coil
uses copper tube and enhanced
aluminum fin and is designed for
optimum heat transfer during heating
and cooling. The vertical air discharge
carries the sound and air up and away
from adjacent patio areas and foliage.
Coils can be cleaned with a common
garden hose.
ExternalServiceValves —Bothservice
valves are brass, front seating type.
Valves are externally located so
refrigerant tube connections can be
madequickly and easily. Each valve hasa
service port for ease of checking
operating refrigerant pressures. The
38YCA has sweat field connections.
The 38YCN has mechanical field
connections.
Warranty — Standard 1 year on
parts. Additional 4 years on
compressor.

Accessory Description and Usage
1. Time-Delay Relay
A SPST delay relay which briefly continues operation of the indoor blower motor to provide additional cooling after the compressor cycles off.
SUGGESTED USE: For improved efficiency ratings for certain combinations of indoor and outdoor units. (Refer to ARI Unitary Directory.)
2. Evaporator Freeze Thermostat
A SPST temperature actuated switch which stops unit operation when evaporator reaches freeze-up conditions.
SUGGESTED USE: All units where low-ambient controller has been added.
3. Isolation Relay
A SPDT relay which switches the low-ambient controller out of the outdoor fan motor circuit when the heat pump switches to heating mode.
SUGGESTED USE: All heat pumps where low-ambient controller has been added.
4. Compressor Start Assist-Capacitor/Relay Type
Start capacitor and start relay gives “hard” boost to compressor motor at each start-up.
SUGGESTED USE: Installations where interconnecting tube length exceeds 50 ft.
Installations where outdoor design temperature exceeds 105
° F (40.6 ° C).
Replacement installations with hard shut-off expansion valve or liquid line solenoid on indoor coil.
Units installed with low-ambient controller.
5. Sound Blanket
Wraparound sound attenuation cover for the compressor. Reduces the sound level by about 0.2 bels.
SUGGESTED USE: Unit installed closer than 15 ft to quiet areas—bedrooms, etc.
Unit installed between 2 houses less than 10 ft apart.
6. Outdoor Thermostat
A SPDT temperature actuated switch which turns on supplemental electric heaters when outdoor air temperature drops below set point.
SUGGESTED USE: Heat pump installations with multiple-stage supplemental heaters
7. Secondary Outdoor Thermostat
A SPDT temperature actuated switch which turns on a third stage of supplemental electric heaters when outdoor air temperature drops below the second-stage
set point.
SUGGESTED USE: Heat pump installations where 3-stage operation of supplemental heaters is desired.
8. Interface Control (Optimizer II)
An electric control for controlling a heat pump and gas or oil furnace system for maximum energy savings. It allows heat pump to operate down to a prede-
termined economic balance point temperature, then switches to allow furnace operation only below that temperature. Requires outdoor thermostat (Item 6) to
be adjusted for economic balance point temperature.
SUGGESTED USE: All heat pump and gas- or oil-fired furnace combination systems.
9. Thermostatic Expansion Valve (TXV)
A modulating flow-control valve which meters refrigerant liquid flow rate into the evaporator in response to the superheat of the refrigerant gas leaving the
evaporator. Kit includes valve, adapter tubes, and external equalizer tube. Both hard shut-off and RPB valves are available.
SUGGESTED USE: For improved system performance in cooling mode.
10. High-Pressure Switch
Auto reset SPST switch activated by refrigerant pressure on high side of refrigerant circuit. Cycles compressor off if refrigerant pressure rises to about 425
psig. Provides additional protection against compressor damage due to loss of outdoor airflow.
SUGGESTED USE: Installations exposed to very “dirty” outdoor air.
Installations where condenser inlet air temperature exceeds 125
° F (51.7 ° C).
11. Filter Drier—Bi-flow
A device for removing contaminants from refrigerant circulating in an air conditioner or heat pump system; bi-flow for heat pumps.
SUGGESTED USE: All field-connected split-system units.
12. Liquid Solenoid Valve (LSV)
An electrically operated shut-off valve to be installed at the outdoor unit and which stops and starts refrigerant liquid flow in response to compressor operation.
Maintains a column of refrigerant liquid ready for action at next compressor operation cycle. Note: Compressor start assist–capacitor/relay type (Item 4) must
be used on single-phase reciprocating compressors.
SUGGESTED USE: In certain long-line applications. (Refer to Long-Line Application Guideline.)
