Carrier’s WeatherMaker 38TSA with
Puron® provides a completely unique

matched by any other family of
equipment. The 38TSA family has been
designed as the first air conditioning
system utilizing Carrier’s unique Puron
refrigerant. The environmentally sound
refrigerant allows you to make a
responsible decision in the protection of
the earth’s ozone layer. Carrier’s
WeatherMaker systems with Puron meet
the Energy Star® guidelines for energy
efficiency.
AVAILABLE OPTIONS
Puron® Environmentally Sound
Refrigerant — Is Carrier’s unique
refrigerant designed to help protect the
environment. Puron is an HFC refrigerant
that does not contain chlorine which is
damaging to the ozone layer. The most
important advantage of Puron refrigerant is
that it has not been banned in future air
conditioning systems as the traditional
refrigerant R-22 has been. Puron
refrigerant is in service in thousands of
systems providing highly reliable,
environmentally sound performance. For
specific R-22 phase out information see
your Carrier distributor.
WeatherArmor™ III System — The
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 the cabinet exterior are
SermaGuard™ coated for a long lasting,
rust-resistant, quality appearance.
The coil is protected by an enhanced
WeatherArmor™ heavy duty inlet grille.
Constructed of a coated 12 gage steel wire
grid and with spacing of 3/8 in., the guard
helps to 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.
High Efficiency Performance — Is
delivered through a combination of
features including Carrier’s Puron
refrigerant, scroll compressor, and
advanced heat transfer surfaces. Efficiency
ratings are 14 SEER (Seasonal Energy
