2
Efficiency Ratio) with enhanced ratings of
up to 15.75 SEER. Sophisticated heat
transfer surfaces utilized in Carrier’s
38TSA design allow heat to easily be
transferred to the outdoor air and requires
less energy. The scroll compressor found in
the 38TSA design performs quietly and
adds to the overall efficiency of the system.
Finally, Carrier’s Puron refrigerant
operates more efficiently than R-22
refrigerant found in other systems. The
efficiency levels provided by the 38TSA
provide end users with lower costs of
operation than traditional air conditioning
systems. 38TSA models are shipped with a
Puron TXV (thermostatic expansion valve)
for field installation. The installation of this
TXV adds to the efficiency of the 38TSA’s.
Assured Future Service
— By utilizing
the environmentally sound refrigerant,
Puron, 38TSA models will remain
serviceable well into the future. The Clean
Air Act of 1990 has placed a cap on
production of most other refrigerants
which has scheduled reductions beginning
in 2004. The resulting cap in production
ultimately results in a complete ban on
many other refrigerants in new equipment
by the year 2010. These changes, required
by federal law, mean the supply of other
refrigerants may be limited in the near
future making Puron the correct choice
when considering long term serviceability.
Highly Reliable Performance
— Is
delivered through the superior design of the
system and componentry. The reliability of
the WeatherMaker models have been
proven to provide the lowest incidence of
warranty service of any product in the
Carrier family in its first 2 years of service.
Long term reliability is assured through the
use of both high and low pressure switches
which will not allow the system to operate
in the event of a significant change in
operating pressure. In doing this, the
system is protected from damage if an
unusual condition arises. Finally, Carrier
includes a special liquid line filter drier
designed to trap moisture and
contaminants which could otherwise
shorten the life of the system.
Carrier’s Silencer System
— Is one of
the most sought after features of the
38TSA family. Extremely low operating
sound is the result of special attention to the
air moving through the outdoor unit, a
specially designed sound enclosure
surrounding the compressor, and an
exclusive laminated plate beneath the
compressor to eliminate sound
transmission to the rest of the system.
Application Versatility
— Carrier’s
systems utilizing Puron refrigerant have
the same application guidelines as other
systems. Applications which include long
line sets (50 to 175 ft) or applications
which require the system to operate at low
outdoor temperatures (below 55°F,
12.8°C) are approved under Carrier’s
standard guidelines.
Carrier Coils and Fan Coils to Complete
the System
— Carrier specially designs
both the outdoor product and indoor coil
products to operate with assured reliability
and performance. A wide range of indoor
coil options are listed in the ratings section
of this publication.
Special Protective Devices
— High and
low pressure switches and internal
protection in the compressor including
temperature and current sensing overloads
prevent operation under potentially
damaging circumstances. A special liquid
line filter drier designed to trap nearly 4
times the volume of contaminants of
standard driers provides superior
protection from moisture trapped in the
system.
Electrical Range
— 208/230v, single
phase.
Wide Range of Sizes
— Available in
four sizes: 2, 2 1/2, 3, and 3 1/2 tons.
Totally Enclosed Fan Motor
—
Protected from adverse weather
conditions.
Unit Design
— Enhanced copper and
aluminum heat transfer surfaces with
vertical air discharge to direct air up and
away from the area.
External Service Valves
— Both service
valves are back seating type valves which
are externally located. These unique valves
allow service technicians to evacuate or
charge the system in less time than
standard service valves.
Easy Serviceability
— Easy removal of
panels and wire dome provides access to
both electrical and refrigerant carrying
components, simplifying installation and
service.
Agency Approvals
— 38TSA models
are listed with UL, c-UL, ARI, CEC, and
CSA-EEV. Special endorsements have
also been awarded these products by
Energy Star® which recognizes energy
efficient products.
Limited Warranty
— A standard one
year warranty on parts with extended
warranty coverage on the compressor for
a total of 10 years. A five year warranty
is offered on the outdoor coil. Optional
warranties are available through your
Carrier distributor.
