STANDARD FEATURES
FACTORY-ASSEMBLED PACKAGE is a compact, fully selfcontained, gas heating/electric cooling unit that is prewired, prepiped, 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 residential and light commercial requirements. Unit installs easily on a rooftop or a ground-level pad.
CONVERTIBLE DUCT CONFIGURATION on the 588A is designed for easy use in either down¯ow or horizontal discharge applications.
HIGH-EFFICIENCY DESIGN with SEERs (Seasonal Energy Ef- ®ciency 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 operation. Each compressor also has vibration isolation to provide quiet operation. Rotary, reciprocating, or scroll compressors are used. Compressors have internal high-pressure and overcurrent protection.
DIRECT-DRIVE MULTISPEED, PSC (permanent split capacitor) BLOWER MOTOR is standard on all models.
DIRECT-DRIVE, PSC CONDENSER-FAN MOTORS are designed to help reduce energy consumption and provide for cooling operation down to 40 F.
REFRIGERANT SYSTEM is designed to provide dependability. Liquid refrigerant strainers are used to promote clean, unrestricted operation. Each unit leaves the factory with a full refrigerant charge. Refrigerant service connections make checking operating pressures easier.
EVAPORATOR AND CONDENSER COILS are computerdesigned for optimum heat transfer and cooling efficiency. Condenser coil is fabricated of copper tube and aluminum ®ns 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 ®n coils for condenser coil are also available by special order. These coils are recommended in applications where aluminum ®ns are likely to be damaged due to corrosion. Copper ®n coils are ideal for seacoast applications.
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.
WEATHERIZED CABINETS are constructed of heavy-duty, phosphated, zinc-coated prepainted steel capable of withstanding 500 hours in salt spray. Interior surfaces of the evaporator compartment are insulated with foil-faced ®berglass 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. 62P. Sloped condensate pan permits an external drain.
LOW SOUND RATINGS ensure a quiet indoor and outdoor environment 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 highquality ®nish ensures an attractive appearance.
LOW AND HIGH VOLTAGE ELECTRICAL ENTRIES allow low and high voltage to be brought in either through the duct panel or rear ¯ue panel.
INTEGRATED GAS CONTROL BOARD provides safe and ef- ®cient control of heating and simpli®es troubleshooting through its built-in diagnostic function.
OPTIONAL BASE RAILS provide holes for rigging and handling as well as an elevated mounting frame that provides structural support for horizontal installations.
DOWNFLOW OPTIONS is converted for down¯ow at factory for easy vertical ductwork connections.
Form No. PDS 588A.18.4B

·Slab-mounted applications when elevation of the unit above the slab is necessary.
·Rooftop application for down¯ow discharge.
·Curbs are preassembled and are available for ¯at or pitched roofs.
Pitched Roof Curb Ð Provided in ratios of 1, 2, 3, 4, 5, and 6 to 12 for use on pitched roof applications.
SUGGESTED USE:
· For when a roof curb is needed on a pitched roof.
Modulating Economizer Ð Economizer is available for down- ¯ow or horizontal applications, and is designed for easy installation. Economizer reduces energy costs and extends equipment life by allowing the use of outdoor air to supply ``free'' cooling when conditions are favorable.
Constant ventilation is recommended for light commercial applications when the conditioned space is occupied.
The economizer is shipped complete with a damper motor and linkage, enthalpy control, low-voltage wiring harness, and a rainhood. Adequate wire lengths are provided (additional ®eldsupplied wires are not required). Horizontal economizers are also furnished with a 2-in. disposable air ®lter and gasket material.
Modulating economizer package consists of low-leakage dampers with controls. The economizer will allow a ®xed percentage of outdoor ventilation air into the unit whenever the evaporator fan is running.
SUGGESTED USE:
·Allows outdoor air to be used for ``free'' cooling whenever the outdoor air is below the enthalpy control setting.
·To reduce energy usage. Use whenever the hours of operation at temperatures below 40 F are signi®cant.
Two-Position Damper Ð In the two-position dampers, the enthalpy control detects when outdoor air is suitable for ``free'' cooling by measuring the outdoor-air dry bulb temperature and humidity. Whenever the outdoor-air quality is acceptable for ``free'' cooling, the outdoor-air damper opens fully and the return-air damper closes, allowing outdoor air to enter the building.
SUGGESTED USE:
·Allows use of outdoor air to cool building without using compressor. Damper closes when evaporator fan is off to prevent cold backdraft, and wasted energy.
Manual Outdoor-Air Damper Ð Package consists of a manually adjustable damper and includes a rainhood and birdscreen.
SUGGESTED USE:
·To allow a ®xed percentage of outdoor air for ventilation under all conditions.
·The damper may be used on either down¯ow or horizontal air- ¯ow applications.
