Carrier 38YCC - Product Features, Quality, and Model; Internal Components and Design; Safety, Quality Assurance, and Model ID

2
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 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.
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.
