Sizes 024 thru 060
Carrier’s technological leadership
has risen to a new level with the
development of the 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, 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 Puron
applications.
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.
FEATURES/BENEFITS
PressureGuard™/Ease of
Installation — Another unique feature
of the WeatherMaker 38YZA is the
patent-pending PressureGuard™,
which enables the use of line sets
currently employed across the
industry. For retrofit applications,
PressureGuard prevents mandatory
replacement of line sets. For new

WeatherMaker 38YZA applications.
Silencer System/Quiet Operation —
The Silencer System features the
InViroFlow™ design, energy-efficient
fan and motor, sound hood and
discharge muffler. The InViroFlow
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
Puron applications, 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. 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.
Patented-Pending Accumulator/
Reliable Operation — Unique to the
WeatherMaker 38YZA is the patent-
pending accumulator, which ensures an
oil rich flow of refrigerant to the
compressor. This oil return is beneficial
especially on start up when compressor-
protecting lubrication is needed most.
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
operationisalsooptimized witha 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 3
field-selectable time periods of 30,
50, and 90 minutes.
Thermostatic Expansion Valve (TXV)
— This unit must be installed with a
Puron TXV on the indoor coil. The FX4
and FV4 indoor fan coils come factory
equipped with a bi-flow Puron 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 TXV must
be installed. See accessory list in this
publication for correct part number.
WeatherArmor III System includes
three components:
—Casing steelisgalvanized andcoated
with a layer of zinc phosphate. A
modifiedpolyesterpowdercoatingis
thenappliedand bakedon, providing
each unit with a hard, smooth finish
that will last for many years.
—All screws on cabinet exterior are
SermaGuard coated for a long-
lasting, rust-resistant, quality
appearance.
—The coil is protected with an
enhanced coil guard. With spacing
of 3/8-in. and construction of coated
12 gage wire, the guard helps protect
from inclement weather (hail),
vandalism, and incidental damage.
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. The
suction service port provides for ease
of checking operating pressure in the
heating mode.
Limited Warranty
—Standard
1-year limited warranty on all parts,
with an additional 9-year limited
warranty on the compressor.
This heat pump can be part of a Comfort Heat Pump System which
can provide up to 15 degree higher heating supply air temperatures,
as well as up to 30 times more humidity removal in cooling mode.
A Comfort Heat Pump System requires the use of a 40FKA (Fan
Coil with Thermidistat Control), or an FV4A Fan Coil with a B-
series Thermidistat Control. See the Comfort Heat Pump System
Product Introduction (CD and 40FKA Product Data) for more
information.
