Efficiency Ratio) with enhanced ratings of
up to 14 SEER. Sophisticated heat transfer
surfaces utilized in Carrier’s 38TZA
design allow heat to easily be transferred
to the outdoor air and requires less energy.
The unique scroll compressor found in the
38TZA design performs quietly and adds
to the overall efficiency of the system.
Finally, Carrier’s Puron® refrigerant
operates more efficiently than ordinary
R-22 refrigerant found in other systems.
The efficiency levels provided by the
38TZA provide end users with lower costs
of operation than traditional air
conditioning systems.
Assured Future Service
— By utilizing
the environmentally sound refrigerant,
Puron®, 38TZA 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 Puron® models have
been proven to provide the lowest
incidence of warranty service of any
product in the Carrier family in its last 3
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 38TZA 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 unique 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 six
sizes: 2, 2-1/2, 3, 3-1/2, 4, and 5 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
panels provide access to both electrical
and refrigerant carrying components
simplifying installation and service.
Agency Approvals
— 38TZA 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.
