The 38YCC 50 Hertz Outdoor
Sections of Split-System Heat Pumps
are designed for quiet, reliable heating
during the winter and cooling during
the summer. With an EER up to 9.2,
these heat pump systems provide
economy of operation through energy
conservation when used with
components designated by Carrier.
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.
FEATURES/BENEFITS
Electrical Range — Units are offered
in single phase 230v 50 Hz. Threephase units are available in sizes 036,
048, and 060 in 400v 50 Hz.
Size Range — The 38YCC is
available in nominal sizes 024, 036,
048 and 060 to meet the needs of
residential and light commercial
applications.
Compressor — Designed
specifically for heat pump duty, with
energy efficiency during heating and
cooling operation. The 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
in the heating mode, and down to
F (12.8°C) in the cooling mode.

Built-in-Reliable Components —
Include a suction-tube accumulator
that reduces the amount of liquid
refrigerant that reaches the
compressor; low-pressure switch to
stop the compressor if refrigerant
charge is lost; crankcase heater on
units with reciprocating compressor
and all 3-phase units to keep
compressor oil warm and free of
refrigerant for maximum lubricity;
internal compressor relief valve for
high-pressure protection.
Discharge Silencer — 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 fieldselectable time periods of 30, 50, and
90 minutes. The control includes builtin 5-minute compressor delay for units
equipped with scroll compressors.
Weather-Protective Cabinet — Steel
is protected with a heavy galvanized
coating and treated 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. Vertical air discharge
carries sound and air up and away from
adjacent patio areas and foliage. Coils
can be cleaned with a common garden
hose.
External Service Valves — Both
service valves are brass, front seating
type. Valves are externally located
so refrigerant tube connections can
be made quickly and easily. Each
valve has a service port for ease of
checking operating refrigerant
pressures. The 38YCC has sweat-type
field connections.
Safety — All units are designed and
manufactured in accordance with
Underwriters Laboratories (U.L. 1995)
standard for safety, heating and
cooling equipment.

Accessory description and usage (Listed alphabetically)
1. Compressor Start Assist — Capacitor and Relay
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 (15.24m).
2. Compressor Start Assist — PTC
Solid-state electrical device which gives a “soft” boost to compressor motor at each start-up.
SUGGESTED USE: Installations with marginal power supply.
3. Cycle Protector
Solid-state timing device which prevents compressor rapid recycling. Control provides an approximate 5-minute delay after power to the compressor
has been interrupted for any reason, including normal room thermostat cycling.
SUGGESTED USE: Installations in areas where power interruptions are frequent.
4. Evaporator Freeze Thermostat
An SPST temperature actuated switch which stops unit operation when evaporator reaches freeze-up conditions.
SUGGESTED USE: All units where Winter Start Control has been added.
5. Filter Drier—Bi-Flow
A device for removing contaminants from refrigerant circulating in a heat pump system: 2-direction flow.
SUGGESTED USE: All split-system heat pumps.
6. 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
426 ± 7 psig and resets at 320 ± 20 psig. Provides protection against compressor damage due to loss of outdoor airflow. To prevent rapid compressor
recycling, Cycle Protector can be used with this switch.
SUGGESTED USE: Installations exposed to very “dirty” outdoor air.
7. 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
predetermined economic balance point temperature, then switches to allow furnace operation only below that temperature. Requires outdoor thermostat
to be adjusted for economic balance point temperature.
SUGGESTED USE: All heat pump and gas- or oil-fired furnace combination systems.
8. Isolation Relay

second-stage set point.
SUGGESTED USE: Heat pump installations where 3-stage operation of supplemental heaters is desired.
15. Sound Hood
Wraparound sound attenuation cover for the compressor. Reduces the sound level by about 2 dBA.
SUGGESTED USE: Unit installed closer than 15 ft (4.55m) to quiet areas—bedrooms, etc.
16. Thermostatic Expansion Valve (TXV) — Bi-Flow
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 shutoff and RPB valves are available.
SUGGESTED USE: For improved system performance in cooling mode for certain combinations of indoor and outdoor units. Refer to ARI Unitary Directory.
17. Time-Delay Relay
An 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.
18. Unit Risers
