One-piece heating and cooling units with low sound levels, easy
installation, low maintenance, and dependable performance.

 

—Factory-assembled package is a com-

pact, fully self-contained, combination gas heating/electric cool-
ing unit that is pre-wired, pre-piped, and pre-charged for
minimum installation expense.
The 582A units are available in a variety of standard and optional
heating/cooling size combinations with voltage options to meet
residential and light commercial requirements. Units are light-
weight and install easily on a rooftop or at ground level. The high
tech composite basepan eliminates rust problems associated
with ground level applications.

 

—Unit is designed

for easy use in either downflow or horizontal applications. Each
unit is easily converted from horizontal to downflow with addition
of two accessory duct covers.

 

 offers SEER (Seasonal Energy Effi-

ciency Ratios) of 10.0 and AFUE (Annual Fuel Utilization Effi-
ciency) ratings as high as 81.1%.

 

saves gas by operating

only when the room thermostat calls for heating. Standard units
are furnished with natural gas controls. A low-cost field-installed
kit for propane conversion is available for all units.

 

 in the thirteenth position of model num-

ber are dedicated Low NOx units designed for California instal-
lations. These models meet the California maximum oxides of
nitrogen (NOx) emissions requirement of 40 nanograms/joule or
less as shipped from the factory and 

 

 be installed in Cali-

fornia Air Quality Management Districts where a Low NOx rule
exists.

 

 are designed for high efficiency. Each compres-

sor is hermetically sealed against contamination to help promote
longer life and dependable operation. Each compressor also has
vibration isolation to provide quieter operation. All compressors
have internal high pressure and overcurrent protection.

 

produce precise air-to-gas mixture,

which provides for clean and efficient combustion. The large
monoport on the inshot (or injection type) burners seldom, if
ever, requires cleaning. All gas furnace components are acces-
sible in one compartment.

 

are constructed of alumi-

nized steel for corrosion resistance and optimum heat transfer
for improved efficiency. The tubular design permits hot gases to
make multiple passes across the path of the supply air.
In addition, dimples located on the heat exchanger walls force
the hot gases to stay in close contact with the walls, improving
heat transfer.

 

 is standard on all 582A models.

 

are designed to

help reduce energy consumption and provide for cooling opera-
tion down to 40°F outdoor temperature. Motormaster® II low am-
bient option is available as a field-installed accessory.

 

is designed to provide dependability. Liq-

uid refrigerant strainers are used to promote clean, unrestricted
operation. Each unit leaves the factory with a full refrigerant
charge. Refrigerant service connections make checking operat-
ing pressures easier.

 

 are computer-designed for

optimum heat transfer and cooling efficiency. The evaporator
coil is fabricated from copper tube and aluminum fins and is lo-
cated inside the unit for protection against damage. The con-
denser coil is internally mounted on the top tier of the unit.
Copper fin coils and pre-coated fin coils are available from the
factory by special order. These coils are recommended in appli-
cations where aluminum fins are likely to be damaged due to
corrosion and are ideal for seacoast applications.
