Single-Package Rooftop Products with Energy-Saving Features
• Direct Spark Ignition
• Low Sound Levels
• Up to 81% AFUE
• 12 SEER
FEATURE/BENEFITS
One-piece heating and cooling units with low sound levels, easy
installation, low maintenance, and dependable performance.
EASY INSTALLATION — Factory-assembled package is a
compact, fully self-contained, combination gas heating/electric
cooling unit that is pre-wired, pre-piped, and pre-charged for
minimum installation expense.
These 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 associ-
ated with ground level applications.
CONVERTIBLE DUCT CONFIGURATION — 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.
EFFICIENT OPERATION
High-Efficiency Design with SEER (Seasonal Energy Effi-
ciency Ratios) of 12.0 and AFUE (Annual Fuel Utilization Effi-
ciency) rating as high as 81%.
Energy-Saving, Direct Spark Ignition 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.
All Units meet the California maximum oxides of nitrogen
(NOx) emission requirements when accessory kit is used.
DURABLE, DEPENDABLE COMPONENTS
Compressors are designed for high efficiency. Each compres-
sor is hermetically sealed against contamination to help pro-
mote longer life and dependable operation. Each compressor
also has vibration isolation to provide quieter operation. All
compressors have internal high pressure and overcurrent
protection.
Monoport Inshot Burners 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.
Turbo-tubular™ Heat Exchangers 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.
Direct-Drive Multi-Speed, PSC (Permanent Split Capacitor)
Blower Motor is standard on all 583A models.
Direct-Drive, PSC Condenser-Fan Motors are designed to
help reduce energy consumption and provide for cooling opera-
tion down to 40 F outdoor temperature. Motormaster
T
II low am-
bient kit is available as a field-installed accessory.
Corporate Thermostats include the Time Guard
T
II anti-short
cycle protection circuitry. If an Original Equipment Manufacture
(OEM) thermostat is used the Time Guard II field-installed anti-
short cycle kit must be used.
Refrigerant System 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.
Evaporator and Condenser Coils 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. A
FIOP (Factory-Installed Option) metal louvered grille is available
on all models. Copper fin coils and pre-coated fin coils are avail-
able from the factory by special order. These coils are recom-
mended in applications where aluminum fins are likely to be
damaged due to corrosion. They are ideal for seacoast
applications.
Low Sound Ratings ensure a quiet indoor and outdoor envi-
ronment with sound ratings as low as 7.2 bels. (See page 3.)
Easy to Service Cabinets provide easy single-panel accessi-
bility to serviceable components during maintenance and instal-
lation. The basepan with integrated drain pan provides easy
ground level installation with or without a mounting pad. Conve-
nient handholds are provided to manipulate the unit on the
