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 Bryant distributor.
UNIT DESIGN —Copper tube, enhanced sine wave alumi-
num fin coil is designed for optimum heat transfer. Vertical air
discharge carries sound and hot condenser air up and away
from adjacent patio areas and foliage. Heat pump style base
pan for easy removal of water, dirt, and leaves.
ELECTRICAL RANGE —All units are offered in single
phase 208/230v. The 030 through 060 sizes are offered in
208/230v 3 phase.
®
533A (60 Hz)
Sizes 024 thru 060
WIDE RANGE OF SIZES —Available in 6 nominal sizes from
024 through 060 to meet the needs of residential and light
commercial applications.
COMPRESSOR —This unit features a scroll compressor,
which is significantly more efficient than conventional compressors. Its simple design offers improved reliability and
each compressor is mounted on rubber isolators for additional sound reduction. Scroll compressors start under most
system loads, minimizing the need for start assistance components. For improved serviceability, all models are
equipped with a compressor terminal plug. Continuous operation is approved down to 55°F (12.8°C) in the cooling mode.
(See cooling performance tables.) Operation down to 0°F or
–20°F is approved when low-ambient requirements are met.
WEATHER-PROTECTIVE CABINET —The access panels
and top are protected with a galvanized coating, then treated
with a layer of zinc phosphate to which a modified polyester
powder coating is applied and baked on. This provides each
unit with a hard, smooth finish that will last for many years.
All screws on cabinet exterior are coated for a long-lasting,
rust-resistant, quality appearance.
TOTALLY ENCLOSED FAN MOTOR —Means greater reli-
ability under adverse weather conditions and dependable
performance for many years. The permanent-split-capacitor
type motor was designed for optimum efficiency. The motor
was tested and qualified under extreme conditions to ensure
the greatest reliability.
APPLICA TION VERSATILITY —The 533A can be combined
with a wide variety of evaporator coils and blower packages
to provide quiet, dependable comfort. Unit can be installed
on a roof or at ground level on a slab.
EXTERNAL SERVICE VALVES —Both service valves are
brass, front seating type with sweat connections. Valves are
externally located so refrigerant tube connections can be
made quickly and easily. Each valve has a service port for
ease of checking operating refrigerant pressures.
EASY SERVICEABILITY —One access panel provides
access to electrical controls and compressor. Removal of
wire dome gives access to fan motor and removal of the top
gives access to the coil.
COMPRESSOR PROTECTION —All compressors are pro-
tected by internal temperature and current sensitive overloads. An internal pressure relief is provided for highpressure protection to the refrigerant system.
Long term reliability is assured through the use of both high
and low pressure switches. Also included is a liquid line filter
drier designed to trap moisture and contaminants, which
could otherwise shorten the life of the system.
LIMITED WARRANTY —Standard 1-year warranty on all
parts. Additional 4-year warranty on compressor.
