FEATURES/BENEFITS

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

GAS HEAT MODELS — All ignition components are contained in the compact IGC (integrated gas controller) 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) simplifies troubleshooting by providing visual fault notification and system status confirmation.

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.

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-notification system reduces service person troubleshooting time and minimizes service costs. The IGC also maximizes heating efficiency by controlling evaporator-fan on and off delays.

Tubular, dimpled gas heat exchangers optimize heat transfer for improved efficiency. The tubular design permits hot gases to make multiple passes across the path of the supply air. The dimpled design creates a turbulent gas flow to maximize heating efficiency.

FEATURES/BENEFITS (cont)

The efficient in-shot burners and all ignition components are contained in an easily removable, compact assembly.

The California Air Quality Management Districts NO ment of 40 nanograms/joule or less is met on 036-060 size Low NO

models.

The extra thick Alumagard™ heat exchanger coating provides corrosion resistance and ensures long life (optional stainless steel heat exchangers are available).

require-

The unsightly appearance of flue 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 flue 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 standard units are designed for natural gas, but an accessory LP (liquid propane) conversion kit is available.

All units have a flame rectification sensor to quickly sense the burner flame and ignite burners almost immediately. Fast shutdown is a certainty since the sensor reacts quickly to any flame 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 flame rollout.

QUIET, EFFICIENT OPERATION AND DEPENDABLE PERFORMANCE — Compressors have vibration isolators for quiet

operation. Efficient fan and motor design permits operation at low sound levels.

Unit sizes 090-300 offer lower utility costs through part-load operation using 2 or 3 stages of cooling.

Quiet and efficient 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.

Increased operating efficiency 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.

DURABLE, DEPENDABLE CONSTRUCTION — 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 finish. The paint finish is non-chalking, and is capable of withstanding ASTM (American Society for Testing and Materials) 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, all size 036-151 units are designed with a single, continuous top piece to eliminate any possible leaks at seams or gasketing. Totally enclosed condenser-fan motors and permanently lubricated bearings provide additional unit dependability.

EASY INSTALLATION AND CONVERSION All Units are Shipped in the Vertical Duct Configuration for

fit-up to standard roof curbs. The contractor can order and install the roof curb early in the construction stage, before decisions on size requirements are made.

All units feature a base rail design with forklift slots and rigging holes for easier maneuvering. Durable packaging protects all units during shipment and storage.

FEATURES/BENEFITS (cont)

The units can be easily converted from a vertical to a horizontal duct configuration by relocating the panels supplied with the unit (size 036-150 only).

To Convert 036-151 Units from vertical to horizontal discharge, simply relocate 2 panels. The same basic unit can be used for a variety of applications and can be quickly modified at the jobsite.

To Convert 155-300 Units from vertical to horizontal discharge, use the optional horizontal supply/return adapter roof curb (581A155,180 and 579F/580F180-300) or accessory conversion kit (581A210-300). Please note that 581A210-300 units are available from the factory configured for horizontal supply/return.

Convenient Duct Openings in the unit basepans permit sideby-side or concentric duct connections (see Application data section) without requiring internal unit modification.

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

Thru-The-Bottom Service Connection Capability comes standard with the rooftop unit to allow power and control wiring and gas connections to be routed through the unit’s basepan, thereby minimizing roof penetrations (to prevent water leaks). (Thru-the-bottom gas connection requires thru-the-bottom accessory kit.) Power, gas and control connections are made on the same side of the unit to simplify installation.

The Non-Corrosive Sloped Condensate Drain Pan (Size 036-150) permits either an external horizontal side con-

densate drain (outside the roof curb) or an internal vertical bottom drain (inside the roof curb). Both options require an external, field-supplied P-trap.

Standard 2-in. Throwaway Filters are easily accessed through a removable panel located above the air intake hood. No tools are required to change unit filters.

Belt-Driven Evaporator-Fan Motors (optional on 580F units under 6 tons) allow maximum on-site flexibility without changing motors or drives.

Low Voltage Wiring Connections are easily made thanks to the large terminal board which is located for quick, convenient access.

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

PROVEN COMPRESSOR RELIABILITY — Design techniques feature computer-programmed balance between compressor, condenser, and evaporator. Bryant-specified hermetic compressors are equipped with compressor overcurrent and overtemperature protection to ensure dependability.

All units have Bryant’s exclusive Acutrol™ (036-150) or TXV (thermostatic expansion valve) metering device (155-300) which precisely controls refrigerant flow, preventing slugging and flood-back, while maintaining optimum unit performance. Refrigerant filter driers are standard.

INTEGRATED ECONOMIZERS AND OUTDOOR-AIR DAMPERS — Available as options or accessories, 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 first stage call for cooling, if the outdoor-air temperature is below the economizer control changeover set point, the mixed-air sensor modulates the economizer outdoor-air damper open to take advantage of free cooling provided by the outside air. 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 first stage of compression is activated and the economizer damper stays at minimum position.

Accessory upgrade kits allow for control by differential dry-bulb temperature (outdoor vs return), outdoor air enthalpy changeover, or more precise differential enthalpy control.

Units can be equipped with different economizer options to meet specific controls applications. The factory-installed or field-installed EconoMi$er IV and EconoMi$er2 are available. The EconoMi$er IV is used with the standard rooftop unit controls and includes an industry standard, stand-alone, solid-state controller. The control can be used with a CO (demand control ventilation) operation. For direct digital control

sensor for DCV

(DDC) applications, the EconoMi$er2 can be operated using a third party control system. The EconoMi$er2 includes 4 to 20 mA actuator capability for demand control ventilation applications.

All economizers incorporate a parallel blade, gear-driven damper system for efficient air mixing and reliable control. In addition, the standard damper actuator includes a spring return to provide reliable closure on power loss. The economizers for sizes 036-151 are equipped with up to 100% barometric relief capability for high outdoor airflow operations. Economizers for unit sizes 036-151 are available, factory-installed, for vertical return only. Economizers for unit sizes 155-300 are compatible for vertical or horizontal return. An optional field-installed barometric relief package is available for size 155-300 units.

In addition, single-stage power exhaust is available as a fieldinstalled accessory for EconoMi$er IV to help maintain proper building pressure.

For units without economizer, year-round ventilation is enhanced by an optional manual outdoor-air damper. On 036150 units, a 25% or 50% manual damper is available as a fieldinstalled accessory. Unit sizes 155-300 are equipped with a manual 25% damper.

SERVICE OPTIONS (581B and 581A Units Only) — Servicing a rooftop unit has never been easier with the factory-installed service options for these rooftop units. These options include the following:

• Hinged access panels are provided for the filter/indoor-fan motor, compressors, evaporator fan, and control box areas. Quick access to major components is accomplished by simply unlatching and swinging open the various panels. Each hinged panel is permanently mounted to the unit, thereby eliminating the concern of a dropped or wind-blown panel puncturing delicate roof materials. The 4 extended access panels are also equipped with ‘‘tie back’’ retaining devices to hold the door in the open position while servicing the unit.

• An external, covered, 115-v Ground Fault Interrupt (GFI) receptacle is provided as a convenient power source for drills, lights, refrigerant recovery units, or other electrical service tools. A factory-supplied step down transformer is connected to the “load” side of the unit main power connection (size 036-

150). For sizes 155-300, connect the outlet to a field-supplied and properly fused branch circuit power supply.

• Slide out “motor-drive-blower” reduces service time (only on 581A210-300).

• An integral non-fused disconnect switch within the rooftop unit reduces installation time, labor and material costs. Safety is assured by an interlock which prevents access to the control box unless the switch is in the OFF position. In addition, the externally mounted handle incorporates power lockout capability to further protect service personnel.

FEATURES/BENEFITS (cont)

INDOOR-AIR QUALITY (IAQ) BEGINS WITH BRYANT ROOFTOPS — Sloped condensate pans minimize biological growth in

rooftop units in accordance with ASHRAE (American Society of Heating, Refrigeration and Air Conditioning Engineers) Standard 62. Two-inch filters with optional dirty filter indicator switch provide for greater particle reduction in the return air. The face-split evaporator coils improve the dehumidification capability of standard units, maximize building humidity control.

Optional proportional reacting CO EconoMi$er IV outdoor air damper option/accessory to aid the IAQ benefits.

PERFECT HUMIDITY™ ADAPTIVE DEHUMIDIFICATION SYSTEM (581B036-150 only) — Bryant’s Perfect Humidity

adaptive dehumidification system is an all-inclusive factoryinstalled option that can be ordered with any 581B rooftop unit to meet the demand for providing a flexible and high performing solution to accommodate all of these design related issues. This system expands the envelope of operation of 581B rooftop products to provide unprecedented flexibility to meet year-round comfort conditions. The Perfect Humidity adaptive dehumidification system has the industry’s only dual dehumidification mode setting. The Perfect Humidity system includes two new modes of operation. The 581B rooftop coupled with the Perfect Humidity system is capable of operating in normal design cooling mode, subcooling mode, and hot gas reheat mode. Normal Design Cooling mode is when the unit will operate under its normal sequence of operation by cycling compressors to maintain comfort conditions. Subcooling mode will operate to satisfy part load type conditions when the space requires combined sensible and a higher proportion of latent load control. Hot Gas

sensor is available with the

Reheat mode will operate when outdoor temperatures diminish and the need for latent capacity is required for sole humidity control. Hot Gas Reheat mode will provide neutral air for maximum dehumidification operation.

EXCLUSIVE HOT GAS REHEAT DEHUMIDIFICATION PACKAGE (581A181-300) — The hot gas reheat dehumidification

package is a result of recent advances by Bryant in controlling comfort levels. This factory-installed option significantly improves the dehumidification capability of the rooftop unit and helps control humidity levels in the building.

This option provides increased dehumidification by cooling the hot liquid refrigerant leaving the condenser coil. The hot gas reheat package consists of a subcooling coil located on the leaving-air side of the evaporator coil. The location of this coil in the indoor airstream enhances the latent capacity of the units by as much as 40%. Many buildings suffer from humidity damage or poor indoor air quality due to humid conditions. The improved latent capacity provided by the hot gas reheat option reduces the building’s humidity, eliminating potential property damage and making the space more comfortable.

The hot gas reheat option is the ideal IAQ option for hot and humid regions. The operation of the hot gas reheat package can be controlled by a field-installed, wall mounted humidistat or Thermidistat™ device. The circuit activates only when needed (using the accessory humidistat) as opposed to some dehumidification systems that operate continuously. The humidistat can be set for any humidity level between 20% and 80% relative humidity. The Thermidistat device can be set for any humidity level between 50% and 90% relative humidity.

Roof Curbs (Horizontal and Vertical) permit installation and

securing of ductwork to curb prior to mounting unit on the curb. Both 14-in. and 24-in. roof curbs are available as field-installed accessories.

EconoMi$er IV is available as a factory-installed option in vertical supply/return configuration only for unit sizes 036-151. Vertical or horizontal configuration is available for unit sizes 155-300. (The EconoMi$er IV is available as a field-installed accessory for horizontal and/or vertical supply return configurations.) The EconoMi$er IV is provided with an industry standard, stand-alone, solid-state controller that is easy to configure and troubleshoot. The EconoMi$er IV is compatible with nonDDC applications. The EconoMi$er IV is equipped with a barometric relief damper capable of relieving up to 100% return air (for unit sizes 036-151 only). Dry bulb outdoor-air temperature sensor is provided as standard. The return air sensor, indoor enthalpy sensor, and outdoor enthalpy sensor are provided as field-installed accessories to provide enthalpy control, differential enthalpy control, and differential dry bulb temperature control.

EconoMi$er IV on 579F and 581A units is used for both vertical and horizontal return air configurations.

EconoMi$er2 is available as a blanket quote control or as a field-installed accessory for horizontal and/or vertical supply return configurations. The EconoMi$er2 is provided without a controller for use with field-installed third-party controls. The EconoMi$er2 is equipped with a barometric relief damper capable of relieving up to 100% return air. Dry bulb outdoor-air temperature sensor is provided as standard. The enthalpy, differential temperature (adjustable), and differential enthalpy control are provided as field-installed accessories. The EconoMi$er2 is capable of control from a 4 to 20 mA signal through optional 4 to 20 mA design without microprocessor control (required for third party control interface).

Manual Outdoor-Air Damper can be preset to admit up to 50% outdoor air for year round ventilation and is available as a fieldinstalled accessory.

Two-Position Damper package is available as an accessory. Both 25% or 100% outdoor air dampers are available.

Head Pressure Control (Motormaster) accessory package maintains condensing temperature between 90 F and 110 F at outdoor ambient temperatures down to –20 F by condenser-fan speed modulation or condenser-fan cycling and wind baffles.

Unit-Mounted, Non-Fused Disconnect Switch provides unit power shutoff. The switch is accessible from outside the unit, provides power off lockout capability and is available as a factory-installed option.

Convenience Outlet is factory-installed and internally mounted with easily accessible 115-v female receptacle.

Compressor Cycle Delay (Time Guard II) accessory prevents unit from restarting for minimum of 5 minutes after shutdown.

Thru-The-Bottom Utility Connectors permit electrical connections to be brought to the unit through the basepan. Connectors are available as field-installed accessories.

Fan/Filter Status Switch accessory provides status of indoor (evaporator) fan (ON/OFF) or filter (CLEAN/DIRTY).

Power Exhaust accessory will provide system exhaust of up to 100% of return air (vertical only). The power exhaust is a fieldinstalled accessory (separate vertical and horizontal design).

Ultraviolet Germicidal Lamps eliminate odor causing mold and fungus that may develop in the wet area of the evaporator section of the unit. The high output, low temperature germicidal lamps are field installed in the evaporator section of the unit, aimed at the evaporator coil and condensate pan.

Hinged Panel Option provides hinged access panels for the filter, compressor, evaporator fan, and control box areas. Filter hinged panels permit tool-less entry for changing filters. Each hinged panel is permanently attached to the rooftop unit. Hinged panels are a factory-installed option.
