FEATURES/BENEFITS

Every compact one-piece unit arrives fully assembled, charged, tested, and ready to run.

INTEGRATED GAS UNIT CONTROLLER (IGC) (All Models) Ð All ignition components are contained in the compact IGC which is easily accessible for servicing. The IGC control board, designed and manufactured exclusively for Bryant rooftop units, provides built-in diagnostic capability. An LED (light-emitting diode) simpli®es troubleshooting by providing visual fault noti®cation and system status con®rmation.

The IGC also contains an exclusive anti-cycle protection for gas heat operation. After 4 continuous cycles on the unit hightemperature limit switch, the gas heat operation is disabled, and an error code is issued. This feature greatly improves reliability of the rooftop unit.

Form No. PDS 580D.36.8

The IGC also contains burner control logic for accurate and dependable gas ignition. The LED is visible without removing the unit control box access panel. This LED fault-noti®cation system reduces service person troubleshooting time and minimizes service costs. The IGC also maximizes heating ef®ciency by controlling evaporator-fan on and off delays.

QUIET, EFFICIENT OPERATION AND DEPENDABLE PERFORMANCE Ð Compressors have vibration isolators for extremely quiet operation. Ef®cient fan and motor design permits operation at very low sound levels and all 580D036-150 units are mounted either on independent mounting rails (036-072) or on an exclusive polycore plate (090-150).

The 580D090-150 and 579F180-300 units offer high energy ef- ®ciency and lower utility costs through part-load operation using 2 stages of cooling.

Quiet and ef®cient operation is provided by belt-driven evaporator fans (standard on all units over 5 tons). The belt-driven evaporator-fan is equipped with variable-pitch pulleys which allow adjustment within the rpm ranges of the factory-supplied pulleys.

A standard (low-medium static) and alternate (high static) drive is available for 579F180-300 units.

Increased operating ef®ciency is achieved through computerdesigned coils featuring staggered internally enhanced copper tubes. Fins are ripple-edged for strength, lanced, and double waved for higher heat transfer.

Tubular, dimpled gas heat exchangers optimize heat transfer for improved ef®ciency. The tubular design permits hot gases to make multiple passes across the path of the supply air. The dimpled design creates a turbulent gas ¯ow to maximize heating efficiency. The extra thick Alumagard™ heat exchanger coating provides corrosion resistance and ensures long life.

The California Air Quality Management Districts NOx requirement of 40 nanograms/joule or less is met when low NOx kit CRLOWNOX001A00 is installed for sizes 036-060.

The unsightly appearance of ¯ue stacks is eliminated and the effects of wind on heating operations are diminished by the induced draft combustion system. The inducer fan draws hot combustion gas through the heat exchanger at the optimum rate for the most effective heat transfer. The heat exchanger operates under negative pressure, preventing ¯ue gas leakage into the indoor supply air.

During the heating mode, the evaporator-fan relay automatically starts the evaporator fan after the heat exchanger warms up to a suitable temperature. The 30-second fan delay prevents cold air from entering the supply duct system when the conditioned space is calling for heat to maximize efficiency.

The direct-spark ignition system saves operating expense when compared to pilot ignition systems. No crossover tube is required, therefore no sooting or pilot fouling problems can occur.

All 580D and 579F standard units are designed for natural gas, but an accessory LP (liquid propane) conversion kit is available, if required.

SAFETY IS BUILT IN Ð All 580D and 579F units have a ¯ame recti®cation sensor to quickly sense the burner ¯ame and ignite burners almost immediately. Fast shutdown is a certainty since the sensor reacts quickly to any ¯ame outage or system failure. In the event of a shutdown, an error code is issued at the IGC board.

Safety is also assured due to the heating safety controls which will shut down the unit if there is a problem. If excessive temperatures develop, limit switches shut off the gas valve. After 4 continuous short cycles of the high-temperature limit switch, the IGC board locks out the gas heat cycle to prevent any further short cycles. This safety feature is provided exclusively on Bryant rooftop units. The rollout switch also deenergizes the gas valve in the event of a ¯ame rollout.

DURABLE, DEPENDABLE CONSTRUCTIONÐ Designed for durability in any climate, the weather-resistant cabinets are constructed of galvanized steel and bonderized, and all exterior panels are coated with a prepainted baked enamel ®nish. The paint ®nish is non-chalking, and is capable of withstanding ASTM B117 500-hour Salt Spray Test. All internal cabinet panels are primed, permitting longer life and a more attractive appearance for the entire unit.

In addition, the 580D090-150 units are designed with a single, continuous top piece to eliminate any possible leaks. Totallyenclosed condenser-fan motors and permanently-lubricated bearings provide additional unit dependability.

EASY INSTALLATION AND CONVERSION Ð All units are shipped in the vertical discharge con®guration for ®t-up to standard roof curbs. (Two different curb sizes ®t unit sizes 036-072 and 090-150, respectively, and one curb size is needed for 180300 units.) The contractor can order and install the roof curb early in the construction stage, before decisions on size requirements are made.

All units feature roll-formed baserail design with forklift slots and rigging holes for easier maneuvering. (Forklift slots are found on 3 sides for 580D036-150 units and on 2 sides for 180-300 units.) The standard 580D036-060 units have operating weights under 500 lb and durable packaging protects all units during shipment and storage.

The units can be easily converted from a vertical to a horizontal discharge con®guration either by interchanging the panels supplied with the unit (sizes 036-150) or by using one of the horizontal supply/return adapter roof curbs (sizes 180-300).

NOTE: On units using horizontal supply and return the accessory barometric relief or power exhaust must be installed on the return ductwork.

Convenient duct openings in the 579F180-300 unit basepans permit side-by-side or concentric duct connections (see Application data section on page 65) without requiring internal unit modi®cation.

The non-corrosive sloped condensate pan permits either an external horizontal side condensate drain (outside the roof curb) or an internal vertical bottom drain (inside the roof curb). Both options require an external, ®eld-supplied P-trap. Also, the condenser coil grille (available on the 036-150 units as a ®eldinstalled accessory provides a metal plate as an alternate location for the ®eld-supplied disconnect, if desired.

The 579F/580D units were designed with service technicians in mind. The single-row condenser coils on the 580D036-060 and 090 units simplify the cleaning process. The ef®cient in-shot burners and all ignition components are contained in an easily removable, compact assembly.

The 580D036-150 units also have a standard ®lter access panel, which permits tool-less ®lter changes, even on units with horizontal economizers.

SIMPLE ELECTRICAL CONNECTIONS Ð Terminal boards, located in the base unit control box, facilitate connections to room thermostat, outdoor thermostat(s), and economizer. Service panels are quickly removed, permitting easy servicing.

Thru-the-bottom service connection capability (sizes 036-150) and thru-the-curb service connections (sizes 180-300) allow power and control wiring to be routed through unit base pan (036-150 units) or curb (180-300 units), minimizing roof penetrations. Both power and control connections are made on the same side of the unit to simplify installation.

In addition, color-coded wires permit easy tracing and diagnostics.

PROVEN COMPRESSOR RELIABILITY Ð Design techniques feature computer programmed balance between compressor, condenser, and evaporator. Hermetic (036-150 units) and semihermetic (180-300 units) compressors with suction and discharge service valves are equipped with compressor overcurrent and overtemperature protection to ensure dependability. Crankcase heaters (180-300 units) prevent refrigerant dilution of oil during off cycles and ensure proper lubrication at start-up to prolong compressor life. Crankcase heaters are not necessary on 036-150 units due to high-side crankcase design (sizes 072,150) and low refrigerant charge levels (sizes 036-150).

The 579F180 unit (with factory-supplied unloading) is equipped with a thermostatic expansion valve to precisely adjust refrigerant ¯ow during Stage 1 (unloaded) operation. All other 579F/ 580D units have the exclusive Acutrol™ metering device which precisely controls refrigerant ¯ow, preventing slugging and ¯ood-back, while maintaining optimum unit performance.

Additional unloaders are not recommended on the 579F180300 units.

INTEGRATED ECONOMIZERS AND OUTDOOR AIR Ð

Optional economizers and manual outdoor-air dampers introduce outdoor air which mixes with the conditioned air, improving indoor air quality and often reducing energy consumption.

During a ®rst stage call for cooling, if the outdoor-air temperature is below the control changeover set point, the discharge-air sensor modulates the economizer outdoor-air damper open to achieve the changeover set point. When second-stage cooling is called for, the compressor is energized in addition to the economizer. If the outdoor-air temperature is above the changeover set point, the ®rst stage of compression is activated and the economizer stays at vent position. Economizer operation is controlled by Accusensor™ I dry-bulb thermostat that senses outdoor-air temperature. Accessory upgrade kits include Accusensor II solid-state enthalpy control (sizes 036-150) and Accusensor III enthalpy sensor.

The Durablade economizer (option or accessory) on the 580D036-150 units has a reliable sliding plate damper which is easily adjusted for 100% outdoor air, 100% return air, or any proportions of mixed air.

The 580D036-150 units can also utilize the optional Parablade economizer. This economizer incorporates a parallel-opposed

blade design with standard enthalpy controls. In addition, the Parablade economizer has a spring return built into the damper motor to provide reliable close-on-power-loss. The Parablade economizer comes equipped with up to 45% barometric relief capability for high outdoor air¯ow applications.

For units without economizer, year-round ventilation is enhanced by a manual outdoor-air damper (ordered as standard on 579F180-300; ordered as an accessory or an option on 580D036-150 units). The damper can be preset to admit up to 25% outdoor air (sizes 180-300) or 50% outdoor air (sizes 036-150).

In addition, the barometric relief damper or power exhaust accessory can be utilized to help maintain proper building pressure.

INDOOR-AIR QUALITY Ð Sloped condensate pans minimize biological growth in rooftop units in accordance with ASHRAE (American Society of Heating, Refrigeration, and Air Conditioning Engineers) Standard 62-89. Two-inch ®lters with optional dirty ®lter indicator switch provide for greater particle reduction in the return air. The face-split evaporator coils improve the dehumidi®cation capability of standard units, and standard enthalpy controls provided with the optional or accessory (sizes 036-150) economizers maximize building humidity control.

036-072 SHOWN

The LP conversion kit allows the unit to utilize a liquid propane fuel supply in areas where natural gas is unavailable, and permits the unit to be converted from natural gas to LP gas use. The kit contains the ori®ces required for LP operation.

Designed speci®cally for use with Bryant commercial systems, this Bryant programmable thermostat features LED occupied/unoccupied displays and setback mode which can override continuous fan operation.

TIME GUARDT II CONTROL

Time Guard II control automatically prevents compressor from restarting for at least 5 minutes after a shutdown. Accessory prevents short cycling of compressor if thermostat is changed rapidly. Time Guard II control mounts in the control compartment of unit.

DURABLADE ECONOMIZER

(SIZES 036-150) PARABLADE ECONOMIZER (SIZES 036-150)

Exclusive Durablade economizer damper design saves energy while providing economical and reliable cooling. A sliding plate on the face of the economizer controls the amount of outdoor air entering the system. Closed, it provides a leakproof seal which prevents ambient air from seeping in or conditioned air from seeping out. It can be adjusted easily for 100% outdoor air or any proportions of mixed air. Like the base unit, the economizer is converted easily for horizontal discharge applications.

The unique design of the Parablade economizer saves energy while providing economical and reliable cooling. The design uses a parallelopposed blade damper. The economizer also has built-in spring return for reliable close-on-power-loss. The Parablade design incorporates standard enthalpy controls and up to 45% barometric relief capability for additional ¯exibility in high outdoor air¯ow applications.

POWER EXHAUST (180-300 SHOWN)

ACCUSENSOR III

SENSOR

+

When used with accessory/optional economizer, the power exhaust accessory helps to relieve building over-pressurization.

NOTE: This accessory is not available with horizontal supply adapter.

Accusensor economizer controls help provide efficient, economical economizer operation. Accusensor II solid-state enthalpy control includes the logic and one sensor to calculate both dryand wet-bulb of the outdoor air to provide an accurate enthalpy reading on 036-150 units. It then decides when to energize the economizer based on this reading. The 180-300 unit economizer provides the decision-making function internally, and requires one Accusensor III sensor for solid-state enthalpy sensing. A second Accusensor III sensor (required for all units for differential enthalpy sensing) compares outdoor temperature and humidity to return-air temperature and humidity and determines the most economical mixture of air (purchased in addition to enthalpy control [sizes 036-150] or to ®rst solid-state enthalpy sensor [sizes 180-300] for differential enthalpy sensing).
