DESCRIPTION

All 588A models feature one piece, compact design and are fully

self-contained units that are prewired, prepiped, and pre-

charged for minimum installation expense. Unit is designed for

easy use in either downﬂow (vertical) or horizontal applications.

STANDARD FEATURES

FACTORY-ASSEMBLED PACKAGE is a compact, fully self-

contained, gas heating/electric cooling unit that is prewired, pre-

piped, and precharged for minimum installation expense.

588A units are lightweight and available in a variety of standard

heating and cooling sizes with voltage options to meet residen-

tial and light commercial requirements. Unit installs easily on a

rooftop or a ground-level pad.

CONVERTIBLE DUCT CONFIGURATION on the 588A is de-

signed for easy use in either downﬂow or horizontal discharge

applications.

HIGH-EFFICIENCY DESIGN with SEERs (Seasonal Energy Ef-

ﬁciency Ratios) of 10.0.

DURABLE, DEPENDABLE COMPRESSORS are designed for

high efficiency. Each compressor is hermetically sealed against

contamination to help promote longer life and dependable op-

eration. Each compressor also has vibration isolation to provide

quiet operation. Rotary, reciprocating, or scroll compressors are

used. Compressors have internal high-pressure and overcur-

rent protection.

TOP QUALITY, TOP RELIABILLITY components, designed

and treated for a minimum of 15 years of operation under the

harshest conditions. Every 588A unit is thoroughly run-tested at

the factory in each operating mode, and is evacuated prior to ﬁ-

nal charging.

DIRECT-DRIVE MULTISPEED, PSC (Permanent Split

Capacitor) BLOWER MOTOR is standard on all models.

DIRECT-DRIVE, PSC CONDENSER-FAN MOTOR is designed

to help reduce energy consumption and provide for cooling op-

eration down to 40 F.

REFRIGERANT SYSTEM is designed to provide dependability.

Liquid refrigerant strainer is 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. Con-

denser coil is fabricated of copper tube and aluminum ﬁns and

is located inside the unit for protection against damage and for

long life and reliable operation. The condenser coil is internally

mounted and protected by a composite grille.

Copper ﬁn coils for condenser coil are also available by special

order. These coils are recommended in applications where alu-

minum ﬁns are likely to be damaged due to corrosion. Copper

ﬁn coils are ideal for seacoast applications.

DIMPLED HEAT EXCHANGERS optimize heat transfer for im-

proved efficiency. The tubular design permits hot gases to stay

in close contact with the cell walls to maximize heat transfer and

efficiency.

THE INDUCED DRAFT COMBUSTION SYSTEM eliminates

the unsightly appearance of ﬂue stacks, and diminishes the ef-

fects of wind on heating operation. The induced draft also pre-

vents contaminants from entering the supply air if a leak in the

heat exchanger occurs.

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, needs cleaning.

INTEGRATED GAS UNIT CONTROLLER (IGC) contains all

the ignition components and is easily accessible for service.

The IGC provides built-in diagnostic capabilities. A light-emitting

diode (LED) simpliﬁes troubleshooting by providing visual fault

notiﬁcation and system status information. The IGC board pro-

vides exclusive anti-short cycle protection for gas heat opera-

tion. The IGC also contains burner control logic for dependable

heating operation. The 588A units maximize heating efficiency

through the IGC’s control of evaporator fan ON/OFF delays.

The IGC helps make 588A units reliable for many years.

WEATHERIZED CABINETS are constructed of heavy-duty,

phosphated, zinc-coated prepainted steel capable of withstand-

ing 500 hours (Federal Test Method Std. No. 141, Method 6061)

in salt spray. Interior surfaces of the evaporator compartment

are insulated with cleanable foil-faced insulation to help keep

the conditioned air from being affected by the outdoor ambient

temperature and provide improved air quality. Conforms to

American Society of Heating, Refrigeration and Air Conditioning

Engineers (ASHRAE) No. 62. Sloped condensate pan requires

external drain trap.

LOW SOUND RATINGS ensure a quiet indoor and outdoor en-

vironment with sound ratings as low as 7.4 bels.

EASY TO SERVICE CABINETS provide easy accessibility to

serviceable components during maintenance and installation.

Rounded corners are an important safety feature, and a high-

quality ﬁnish ensures an attractive appearance.

STANDARD FEATURES (cont) evaporator-fan motors, and control boards, while the gas sections use common inducer motors, limit switches, and roll-out switches. This allows for greater inventory control, familiarity of parts, and fewer stocked parts. OPTIONAL BASE RAILS provide holes for rigging and forklift handling as well as an elevated mounting frame that provides structural support for horizontal installations. Ideal for light commercial applications.

OPERATING SEQUENCE The normally-open contacts of energized contactor (C) close and complete the circuit through compressor motor (COMP) and condenser (outdoor) fan motor (OFM). Both motors start instantly. The set of normally-open contacts of energized relay BR close and complete the circuit through evaporator blower (indoor) fan motor (IFM). The blower motor starts instantly. NOTE: Once the compressor has started and then has stopped, it should not be started again until 5 minutes have elapsed.
