with Puron
®
Refrigerant
Sizes 018 thru 060
Carrier’s technological leadership
has risen to a new level with the
development of the Performance™
Series 38YZA Heat Pump, the outdoor
section of a superior split heat pump
system. This leadership effort has
yielded a product that appeals to
consumers for all of its unique benefits.
Puron®, the environmentally sound
refrigerant — The first unique feature
of the 38YZA is the environmentally
sound nature of Puron, which provides
the homeowner with additional peace
of mind because their heating and
cooling system’s refrigerant has zero
ozone-depletion potential.
Second, thanks to the performance
advantage of Puron-refrigerant, the
38YZA is extremely efficient. In fact,
the 38YZA features some of the lowest
energy usages of single speed heat
pumps available from Carrier.
Maximum performance and
efficiency are made possible through
the use of the FX4A and FV4A fan
coils, custom made for applications
with Puron refrigerant.
Third, the cost of service will
potentially be reduced in the future as
the industry’s older refrigerant, R-22
is gradually phased out through
Federally legislated production
limitations.
Carrier’s Infinity® Controls — These
industry-leading controls, when installed
with Carrier’s Ideal Humidity™
variable-speed furnaces or fan coils,
provide the homeowner with:
–unparalleled control of temperature,
humidity, indoor air quality, and zoning
–unprecedented ease of use
–simple operation through on-screen,
text-based service reminders
Optional remote access through
telephone or Internet is also available

FEATURES/BENEFITS
Silencer System/Quiet Operation —
The Silencer System features the
Silencer™ top design, energy-efficient
fan and motor, sound hood and
discharge muffler. The Silencer Design
improves airflow patterns and requires
less energy. The energy efficient fan
and fan motor add to quiet operation
while moving air more efficiently. The
sound hood muffles noise from the
operation. The discharge muffler
minimizes low frequency
sound and pressure pulsation generated
by the compressor discharge gas.
Compressor — The 38YZA features
the efficient Copeland Scroll
compressor, specially designed for
applications using Puron refrigerant,
with its thicker shell, and an anti-reverse
rotation device for superior reliability
and quiet operation. In addition, each
compressor is mounted on rubber
isolators for additional sound reduction.
For improved serviceability, all models
are equipped with a compressor terminal
plug. The scroll compressor will start
under most system loads, thus
eliminating the need for start assisting
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.) The scroll
compressor is covered with a standard
10-year limited warranty.
Accumulator/Reliable Operation —
A properly sized accumulator which
minimizes liquid refrigerant from
reaching the compressor is standard on
this unit.
Built-In Reliable Components —
The 38YZA’s principal feature of
compressor protection is further
enabled by a high pressure switch; a
discharge temperature switch for
compressor overtemperature
protection; and a low pressure switch
for loss of charge protection. Reliable
operation is also optimized with a heavy
duty, quiet and easy to service reversing
valve.
Defrost Control Board — This board
incorporates a built-in 5-minute
compressor time-delay relay, defrost
relay, defrost timer, and low-voltage
terminal board. The defrost control
is a time/temperature initiation/
termination control which includes 4
field-selectable (DIP switch) time
periods of 30, 60, 90, and 120 minutes.
This control also includes a field-
selectable (DIP switch) Quiet Shift
defrost mode which, if selected,
maintains extremely quiet operation
during defrost.
Thermostatic Expansion Valve (TXV)
— This unit must be installed with a
Puron-refrigerant TXV on the indoor
coil. The FX4 and FV4 indoor fan coils
come factory equipped with a bi-flow
Puron-refrigerant TXV. When installed
in this application, no further change is
required. If any other indoor fan coil or
furnace coil is used, an accessory bi-flow
Puron-refrigerant TXV must be
installed. See accessory list in this
publication for correct part number.
WeatherArmor™ III System includes
three components:
— Casing steel is galvanized and coated
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
ceramic coated for a long-lasting,
rust-resistant, quality appearance.
—The coil is protected with an
enhanced WeatherArmor™ heavy
duty inlet grille. With spacing
of 3/8-in. and construction of coated
wire, the guard helps 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 rain and snow
conditions. The large, wraparound coil
uses copper tubing and enhanced sine
wave aluminum fins 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.
Rows of composite coils can be cleaned
with a common garden hose.
External Service Valves —Both service
valves are the brass, back seating type
with sweat connections. Each valve
has a service port for ease of checking
operating refrigerant pressures. A
separate suction service port provides for
ease of checking operating pressure in the
heating mode.
Limited Warranty —5-year limited
warranty on all parts and 10-year
limited warranty on the compressor.
