Model Number Nomenclature - Carrier 38YCG Product Data

Reliable Standard 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 036 and 060 sizes 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.
Weather-Protective Cabinet — The
casing steel is protected with a

galvanized coating and treated with a
layer of zinc phosphate. A 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.
Heavy Duty Inlet Grille —The
WeatherArmor™ coil protector, made of
a coated steel wire grid with vertical 3/8-
in. spacing, is designed to help protect
the coil from inclement weather,
vandalism, and incidental damage. It
provides protection while not restricting
airflow and maintaining ease of coil
inspection and cleaning.
Unit Design — All units are equipped
with totally enclosed fan motors for
greater reliability under adverse weather
conditions. The large, wraparound coil
uses copper tube and enhanced
aluminum fin and is designed for

REGISTERED QUALITY SYSTEM
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.
Coil 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
38YCG has sweat field connections.
Additional Standard Features —
Included as standard on this model is
compressor protection through factory-
installed accumulator and low-pressure
switch.
Limited Warranty — Standard 5-year
limited warranty on unit parts and 5-year
limited warranty on compressor.
