each unit with a hard, smooth finish that will last for many years.
All screws on cabinet exterior are ceramic coated for a longlasting, rust-resistant, quality appearance.
HEAVY DUTY INLET GRILLE —The DuraGuard™ coil protec-
tor, made of a coated steel wire grid with vertical 3/8 in. spacing,
is designed to help 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.
TOTALLY ENCLOSED FAN MOTOR —Means greater reliability
under adverse weather conditions and dependable performance for many years. The permanent-split-capacitor type
motor was designed for optimum efficiency. Then the motor was
tested and qualified under extreme conditions to help ensure
the greatest reliability.
UNIT DESIGN —Copper tube, enhanced aluminum 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 drain pan for easy
removal of water, dirt, and leaves.
BRYANT’S AEROQUIET SYSTEM —Extremely low operating
sound is the result of special attention to the air moving through
the outdoor unit, and a specially designed sound enclosure surrounding the compressor to eliminate sound transmission to the
rest of the systems.
APPLICATION VERSATILITY —The 593C 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.
to electrical controls and compressor. Removal of wire dome
gives access to fan motor and removal of the top gives access
to the coil. For improved serviceability, all models are equipped
with a compressor terminal plug.
COMPRESSOR PROTECTION —Each model is protected with
internal temperature- and current-sensitive overloads. An internal pressure relief valve provides high-pressure protection to
the refrigerant system.
LIMITED WARRANTY —Standard 5-year warranty on all parts,
with an additional 10-year warranty on compressor.
