II580J 17-30
Single Package Rooftop with Gas Heat/Electric Cooling
Vertical Air Flow Unit with Puron
580J units for installation in the United States contain use of Bryant's 2-speed indoor fan control system.
This complies with the U.S. Department of Energy (DOE) efficiency standard of 2018.
580J units for installation outside the United States may or may not contain use of the 2-speed indoor fan
control system as they are not required to comply with the U.S. Department of Energy (DOE) efficiency
standard of 2018.

SAFETY CONSIDERATIONS
Improper installation, adjustment, alteration, service, mainte-
nance, or use can cause explosion, fire, electrical shock or other
conditions which may cause personal injury or property damage.
Consult a qualified installer, service agency, or your distributor
or branch for information or assistance. The qualified installer or
agency must use factory-authorized kits or accessories when
modifying this product. Refer to the individual instructions pack-
aged with the kits or accessories when installing.
Follow all safety codes. Wear safety glasses and work gloves.
Use quenching cloths for brazing operations and have a fire
extinguisher available. Read these instructions thoroughly and
follow all warnings or cautions attached to the unit. Consult local
building codes and appropriate national electrical codes (in
USA, ANSI/NFPA70, National Electrical Code (NEC); in
Canada, CSA C22.1) for special requirements.

It is important to recognize safety information. This is the
safety-alert symbol
and in instructions or manuals, be alert to the potential for
personal injury.
Understand the signal words DANGER, WARNING,
CAUTION, and NOTE. These words are used with the safety-
alert symbol. DANGER identifies the most serious hazards
which will result in severe personal injury or death. WARNING
signifies hazards which could result in personal injury or death.
CAUTION is used to identify unsafe practices, which may result
in minor personal injury or product and property damage. NOTE
is used to highlight suggestions which will result in enhanced
installation, reliability, or operation.
Failure to follow this warning could result in personal
injury or death. Disconnect gas piping from unit when leak
testing at pressure greater than 0.5 psig (3450 Pa). Pres-
sures greater than 0.5 psig (3450 Pa) will cause gas valve
damage resulting in hazardous condition. If gas valve is
subjected to pressure greater than 0.5 psig (3450 Pa), it
must be replaced before use. When pressure testing field-
supplied gas piping at pressures of 0.5 psig (3450 Pa) or
less, a unit connected to such piping must be isolated by
closing the manual gas valve.
Failure to follow this warning could cause personal injury
or death. Before performing service or maintenance opera-
tions on unit, always turn off main power switch to unit and
install lock(s) and lockout tag(s). Unit may have more than
one power switch.
!
Failure to follow this warning could cause personal injury,
death and/or equipment damage.
