Easy to install:

These new Legacy Line units are designed for dedicated factory--supplie d vertical or horizontal air flow duct configurations. No special field kits are required. Designed to fit on pre--installed curbs by another manufacturer, these units also fit on past designed Bryant installed curbs with an adapter curb. This new cabinet design also integrates a large control box that gives you room to work and room to mount Bryant accessory controls.

Easy to maintain:

Easy access handles by Bryant provide quick and easy access to all normally serviced components. Our “no--strip” screw system has superior holding power and guides screws into position while preventing the screw from stripping the unit’s metal. Take accurate pressure readings by reading system pressures with panels in place as compressors are strategically located to eliminate any air bypass.

Easy to use:

The newly designed, master terminal board by Bryant puts all your connections and troubleshooting points in one convenient place, standard. Most low voltage connections are made to the same board and make it easy to find what you’re looking for and easy to access it. Bryant rooftops have high and low pressure switches, a filter drier, and 2--in (51mm) filters standard.

Reliable:

Each unit comes with precision sized and tested scroll compressor that is internally protected from over temperature and pressures. In addition, each refrigerant circuit is further protected with a high pressure and low pressure switch as well as containing a liquid line filter drier. Each unit is factory tested prior to shipment to help ensure unit operation once properly installed.

FACTORY OPTIONS AND/OR ACCESSORIES

Economizer (dry--bulb or enthalpy)

Economizers save money. They bring in fresh, outside air for ventilation; and provide cool, outside air to cool your building. This is the preferred method of low--ambient cooling. When coupled to CO provide even more savings by coupling the ventilation air to only that amount required.

Economizers are available, installed and tested by the factory, with either enthalpy or dry--bulb temperature inputs. There are also models for electromechanical as well as direct digi tal controllers. Addit ional sensors are available as accessories to optimize the economizers.

Economizers include gravity controlled, barometric relief equalizes building pressure and ambient air pressures.

levels decrease, and

Smoke Detectors

Non--Fused Disconnect

This OSHA--compliant, factory--installed, safety switch allows a service technician to locally secure power to the rooftop.

Power Exhaust with Barometric Relief

Superior internal building pressure control. This field--installed accessory or factory--installed option may eliminate the need for costly, external pressure control fans.

RTU Open Protocol Controller

Connect the rooftop to an existing BAS without needing complicated translators or adapter modules using the RTU Open controller. This new controller speaks the 4 most common building a utomation system languages (Bacnet, Modbus, N2, and Lonworks). Use this controller when you have an existing BAS.

Time Guard II Control Circuit

This accessory protects your compressor by preventing short--cycli ng in the event of some other fail ure, prevents the compressor from restarting for 30 seconds after stopping. Not required with RTU Open or authorized commercial thermostats.

Motorized 2--Position Damper

The new Bryant 2--position, motorized outdoor air damper admits up to 100% outside air. Using reliable, gear--driven technology, the 2--position damper opens to allow ventilation air and closes when the rooftop stops, stopping unwanted infiltration.

Trust the experts. Smoke detectors make your application safer and your job easier. Bryant smoke detectors immediately shut down the rooftop unit when smoke is detected. They are available, installed by the factory, for supply air, return air, or both.

Louvered Hail Guards

Sleek, louvered panels protect the condenser coil from hail damage, foreign objects, and incidental contact.

Convenience Outlet (powered or un--powered)

Reduce service and/or installation costs by including a convenience outlet in your specification. Bryant will install this service feature at our factory. Provides a convenient, 15 amp, 115v GFCI receptacle with “Wet in Use” cover. The “powered” option allows the installer to power the outlet from the line side of t he disconnect side as required by code. The “unpowered” option is to be powered from a separate 115/120v power source.

Manual OA Damper

Manual outdoor air dampers are an economical way to bring in ventilation air. The dampers are available in 25% versions.

Optional P erfect Humidityt Adaptive Dehumidification System

Bryant’s Perfect Humidity adaptive dehumidification system is an all--inclusive factory installed option that can be ordered with any Legacy Line 580J17--28 rooftop unit.

This system expands the envelope of operation of Bryant’s Legacy Line 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.

FACTORY OPTIONS AND/OR ACCESSORIES (cont.)

The Legac y Line 580J17--28 rooftop coupled with the Perfect Humidityt 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 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.

Optional Stainless Steel Heat Exchanger

The stainless steel heat exchanger option provides the tubular heat exchanger be made out of a minimum 20 gauge type 409 stainless steel for applications where the mixed air to the heat exchanger is expected to drop below 45_F(7_C). Stainless steel may be specified on applications where the presence of airborne contaminants require its use (applications such as paper mills) or in area with very high outdoor humidity that may result in severe condensation in the heat excha nger during cooling operation.

Flue Discharge Deflector

Motormaster Head Pressure Controller

The Motormaster motor controller is a low ambient, head pressure controller kit that is designed to maintain the unit’s condenser head pressure during periods of low ambient cooling operation. This devi ce should be used as an alternative to economizer free cooling not when economizer usage is either not appropriate or desired. The Motormaster will either cycle the outdoor--fan motors or operate them at reduced speed to maintain the unit operation, depending on the model.

Winter Start Kit

The winter start kit by Bryant extends the low ambient limit of your rooftop to 25_F(--4_C). The kit bypasses the low pressure switch, preventi ng nuisance tripping of the low pressure switch. Other low ambient precautions may still be prudent.

Propane Heating

Convert your gas heat rooftop from standard natural gas operation to Propane using this field--installed kit.

High Altitude Heating

High altitudes have less oxygen, which means heat exchangers need less fuel. The new gas orifices in this field--installed kit make the necessary adjustment for high altitude applications. They restore the optimal fuel to air mixture and maintain healthy combustion at altitudes above 2000 ft (610m). Kits may not be required in all areas.

The flue discharge deflector is a useful accessory when flue gas recirculation is a concern. By venting the flue discharge upwards, the deflector minimizes the chance for a neighboring unit to intake the flue exhaust.

Alternate Motors and Drives

Some applications need larger horsepower motors, some need more airflow, and some need both. Regardless of the case, your Bryant expert has a factory installe d combination to meet your application. A wide selection of motors and pulleys (drives) are available, factory installed, to handle nearly any application.

Thru--the--Base Connections

Thru--the--base connections, available as a factory option, are necessary to ensure proper connection and seal when routing wire and piping through the rooftop’s basepan and curb. These couplings eliminate roof penetration and should be considered for gas lines, main power lines, as well as control power.

Barometric Hood

For Horizontal Economizer applications where relief damper is installed in duct work. This kit provides the needed protection.

APPLICATION/SELECTION DATA

Min operating ambient temp (cooling):

In mechanical cooling mode, your Bryant rooftop unit can safely operate down to an outdoor ambient temperature of 30_F(--1_C). It is possible to provide cooling at lower outdoor ambient temperatures by using less outside air, economizers, and/or accessory low ambient kits.

Max operating ambient temp (cooling):

The maximum operating ambient temperature for cooling mode is 115_F(46_C). While cooling operation above 115_F(46_C) may be possible, it could cause either a reduction in performance, reliability, or a protective action by the unit’s internal safety devices.

Min mixed air temp (heating):

580J

Using the factory settings, the minimum temperatures for the mixed air (the combined temperature of the warm return air and the cold outdoor air) entering the dimpled, gas heat exchangers are:

Aluminized Stainless Steel

50_F(10_C) continuous

45_F(7_C) intermittent

Operating at lower mixed--air temperatures may be possible, if a field--supplied, outdoor air thermostat initiates both heat stages when the temperature is less than the minimum temperatures listed above. Please contact your local Bryant representative for assistance.

40_F(4_C) continuous

35_F(2_C) intermittent

Min and max airflow (heating and cooling):

To maint ain safe and reliable operation of your rooftop, operate within the heating airflow limits during heating mode and cooling airflow limits during cooling mode. Operating above the max may cause blow--off, undesired airflow noise, or airflow related problems with the rooftop unit. Operating below the min may cause problems with coil freeze--up and unsafe heating operation. Heating and cooling limitations differ when evaluating operating CFM, the minimum value is the HIGHER of the cooling and heating minimum CFM values published in Table 5 and the maximum value is the LOWER of the cooling and heating minimum values published in Table 5.

Heating--to--cooling changeover:

Your unit will automatically change from heating to cooling mode when using a thermostat with an auto--change--over feature.

All units are draw--through in cooling mode and blow--through in heating mode.

Outdoor air application strategies:

Economizers reduce operating expenses and compressor run time by providing a free source of cooling and a means of ventilation to match application changing needs. In fact, they should be considered for most applications. Also, consider the various economizer control methods and their benefits, as well as sensors required to accomplish your application goals. Please contact your local Bryant representative for assistance.

Motor limits, break horsepower ( BHP) :

Due to internal design of Bryant units, the air path, and specially designed motors, the f ull horsepower (maximum continuous BHP) band, as listed in Physical Data Table Cooling, can be used with the utmost confidence. There is no need for extra safety factors, as Bryant motors are designed and rigorously tested to use the entire, listed BHP range without either nuisance tripping or premature motor failure.

Propane heating:

Propane has different physical qualities than natural gas. As a result, Propane requires different fuel to air mixture. To optimize the fuel/air mixture for Propane, Bryant sells different burner orifices in an easy to install accessory kit. To select the correct burner orifices or determine the hea t capacity for an Propane application, use either the selection software, or the unit’s service manual.

High altitude heating:

High altitudes have less oxygen, which affects the fuel/air mixture in heat exchangers. In order to maintain a proper fuel/air mixture, heat exchangers operating in altitudes above 2000 ft (610m) require different orifices. To select the correct burner orifices or determine the heat capacity for a high altitude application, use either the selection software, or the unit’s service manual.

NOTE: Typical natural gas heating value ranges from 975 to 1050 Btu/ft value goes down approximately 1.7% per every thousand feet elevation. Standard factory orifices can typically be used up to 2000 ft (610m) elevation without any operational issues.

NOTE: For installations in Canada, the input rating should be derated by 10% for altitudes from 2000 ft (610m) to 4500 ft (1372m) above sea level.

Sizing a rooftop

Bigger isn’t necessarily better. While an air conditioner needs to have enough capacity to meet the design loads, it doesn’t need excess capacity. In fact, excess capacity typically results in very poor part load performance and humidity control.

Using higher design temperatures than ASHRAE recommends for your location, adding “safe ty factors” to the calculated load, are all signs of oversizing air conditioners. Oversizing the air conditioner leads to poor humidity control, reduced efficiency, higher utility bills, larger indoor temperature swings, excessive noise, and increased wear and tear on the air conditioner.

Rather than oversizing an ai r conditioner, engineers should “right--size” or even slightly undersize air conditioners. Correctly sizing an air conditioner controls humidity better; promotes efficiency; reduces utility bills; extends equipment life, and maintains even, comfortable temperatures. Please contact your local Bryant representative for assistance.

Low ambient applications

The optional Bryant economizer can adequately cool your space by bringing in fresh, cool outside air. In fact, when so equipped, accessory low--ambient kit may not be necessary. In low ambient conditions, unless the outdoor air is excessively humid or contaminated, economizer--based “free cooling” is the preferred less costly and energy conscious method.

In low ambient applications where outside air might not be desired (such as contaminated or excessively humid outdoor environments), your Bryant rooftop can operate to ambient temperatures down to -- 20_F(--29_C) using the recommended accessory Motormaster low ambient controller or down to 25_F(--4_C) with the field installed Winter Start Package.

Application/Selection Option

Selection software by Bryant saves time by performing many of the steps above. Contact your Bryant sales representative for assistance.

General fan performance notes:

1. Interpolation is permissible. Do not extrapolate.

2. External stat ic pressure is the stat ic pressure difference between the return duct and the supply duct plus the static pressure caused by any FIOPs or accessories.

3. Tabular data accounts for pressure loss due to clean filters, high gas heat, unit casing, and wet coils. Factory options and accessories may add static pressure losses, as shown in the table above. Selection software is available, through your salesperson, to help you select the best motor/drive combination for your application.

4. The Fan Perform ance tables offer motor/drive recommendations. In cases when two motor/drive combinations would work, Bryant recommended the lower horsepower option.

5. For information on the electrical properties of Bryant motors, please see the Electrical information section of this book.

6. For m ore information on the performance limits of Bryant motors, see the application data section of this book.

SEQUENCE OF OPERATION

General

The sequence below describes the sequence of operation for an electro--mechanical unit with and without a factory installed EconoMi$ert IV (called “economizer” in this sequence). For informa tion regarding a direct digital controller, see the start--up, operations, and troubleshooting manual for the applicable controller.

Electro--mechanical units with no economizer

Cooling —

When the thermostat calls for cooling, terminals G and Y1 are energized. As a result, the indoor--fan contactor (IFC) and the compressor contactor (C1) are energized, causing the indoor--an motor (IFM), compressor #1, and outdoor

580J

fan to start. If the unit has 2 stages of cooling, the thermostat will additionally energize Y2. The Y2 signal will energize compressor contactor #2 (C2), causing compressor #2 to start. Regardless of the number of stages, the outdoor--fan motor runs continuously while unit is cooling.

Heating —

NOTE: Legacy Linet (580J) units have 2 stages of gas

heat.

When the thermostat calls for heating, power is sent to W on the Integrated Gas Controller (IGC) board. An LED (light--emitting diode) on the IGC board turns on and remains on during normal operation. A c heck is made to ensure that the rollout switch and limit switch are closed. If the check was successful, the induc ed--draft motor is energized, and when its speed is satisfactory, as proven by the “hall effect” sensor, the ignition activation period begins. The burners will ignite within 5 seconds. If the burners do not light, there is a 22--second dela y before another 5--second attempt. This sequence is repeated for 15 minutes or until the burners light. If, after the 15 minutes, the burners still have not lit, heating is locked out. To reset the control, break 24--v power to the thermostat.

When ignition occurs, the IGC board will continue to monitor the condition of the rollout switch, the limit switches, the “hall effect” sensor, as well as the flame sensor. Forty--five seconds after ignition occurs, a ssuming the unit is controlled through a room t hermostat set for fan auto, the indoor--fan motor will energize (and the outdoor--air dampers will open to their minimum position). If, for some reason, the over--temperature limit opens prior to the start of the indoor fan blower, the unit will shorten the 45--second delay to 5 seconds less than the time from initiation of heat to when the limit tripped. Gas will not be interrupted to the burners and heating will continue. Once the fan--on delay has been modified, it will not change back to 45 seconds until power is reset to the control.

On units with 2 stages of heat, when additional heat is required, W2 closes and initiates power to the second stage of the main gas valve. When the thermostat is satisfied, W1 and W2 open and the gas valve closes, interrupting the flow of gas to the main burners.

If the call for W1 lasted less than 1 minute, the heating cycle will not terminate until 1 minute after W1 became active. If the unit is controlled through a room therm ostat set for fan auto, the indoor--fan motor will continue to operate for an additional 45 seconds then stop. If the over--temperature limit opens after the indoor motor is stopped, but within 10 minutes of W1 becoming inactive, on the next c ycle the time will be extended by 15 seconds. The maximum delay is 3 minutes. Once modified, the fan off delay will not change back to 45 seconds unless power is reset to the control. A LED indicator is provided on the IGC to monitor operation.

Electro--mechanical units with an economizer

Cooling —

When free cooling is not available, the compressors will be controlled by the zone thermostat. When free cooling is available, the outdoor--air damper is modulated by the EconoMi$er IV control to provide a 50_F(10_C) to 55_F (13_C) mixed--air temperature into the zone. As the mixed air temperature fluctuat es above 55_F(13_C)or below 50_F(10_C) dampers will be modulated (open or close) to bring the mixed--air temperature back within control. If mechanical cooling is utilized with free cooling, the outdoor--air damper will maintain its current position at the time the compressor is started. If the increase in cooling capacity causes the mixed--air temperature to drop below 45_ F(7_C), then the outdoor --air damper position will be decreased to the minimum position. If the mixed--a ir temperature continues to fall, the outdoor--air damper will close. Control returns to normal once the mixed--a ir temperature rises above 48_F(9_C). The power exhaust fans will be energized and de--energized, if installed, as the outdoor--air damper opens and closes.

If field--installed accessory CO the EconoMi$er IV control, a demand controlled ventilation strategy will begin to operate. As the CO level in the zone increases above the CO2setpoint, the minimum position of the damper will be increased proportionally. As the CO increase in fresh air, the outdoor--air damper will be proportionally closed. For EconoMi$er IV operation, there must be a thermostat call for the fan (G). If the unit is occupied and the fan is on, the damper will operate at minimum position. Otherwise, the damper will be closed.

When the EconoMi$er IV control is in the occupied mode and a call for cooling exists (Y1 on the thermostat), the control will first check for indoor fan operation. If the fan is not on, then cooling will not be activated. If the fan is on, then the control will open the Ec onoMi$er IV damper to the minimum position.

sensors are connected to

level decreases because of the

SEQUENCE OF OPERATION (cont.)

On the initial power to the EconoMi$er IV control, it will take the damper up to 2--1/2 minutes before it begins to position itself. After the initial power--up, further changes in damper position can take up to 30 seconds to initiate. Damper movement from full closed to full open (or vice versa) will take between 1--1/2 and 2--1/2 minut es. If free cooling can be used as determined from the appropriate changeover command (switch, dry bulb, enthalpy curve, differential dry bulb, or di fferential enthalpy), then the control will modul ate the dampers open to maintain the mixed--a ir temperature setpoint at 50_F(10_C) to 55_F (13_C). If there is a further demand for cooling (cooling second stage -- Y2 is energized), then the control will bring on compressor stage 1 to maintain the mixed--air temperature setpoint. The EconoMi$er IV damper will be open at maxim um position. EconoMi$er IV operation is limited to a single compressor.

The Perfect Humidity option includes additional valves in the liquid line and discharge line of each refrigerant circuit, a small reheat condenser coil downstream of the evaporator, and Motormaster variable--speed control of some or all outdoor fans. Operation of the revised refrigerant circuit for each mode is described below.

NOTE: x = refrigerant circuit A, B, or C.

Normal Cooling

Refrigerant flows from the outdoor condenser through the normally open Cooling Valve (CV.x) to the expansion device. Reheat1 Valve (RH1.x) and Reheat2 Valve (RH2.x) are closed.

Reheat1 (Subcooling Mode) -- 580J17--28

580J

Heating —

The sequence of operation for the heating is the same as an electromechanical unit with no economizer. The only difference is how the economizer acts. The economizer will stay at the Economizer Minimum Position while the evaporator fan is operating. The outdoor--air damper is closed when the indoor fan is not operating.

Refer to Service and Maintenance Manual for further details.

Optional Perfect Humidityt Dehumidification System

Units with the factory equipped Perfect Humidity option are capable of providing multiple modes of improved dehumidification as a variation of the normal cooling cycle.

RH2.x

This mode increases latent cooling and decreases sensible cooling compared to normal cooling. Refrigerant flows from the outdoor condenser, through the normally open Reheat1 Valve (RH1.x), and through the reheat condenser coil to the expansion device. Cooling Valve (CV.x) and Reheat2 Valve (RH2.x) are closed.

Reheat2 (Hot Gas Reheat Mode) -- 580J17--28

This mode provides maximum latent cooling with little to no sensible capacity. This mode can operate to provide dehumidification when there is no cooling demand. Like Reheat1 mode, refrigerant flows from the outdoor condenser, through the normally open Reheat1 Valve (RH1.x), and through the reheat condenser coil to the expansion device. The Cooling Valve (CV.x) is closed. Reheat2 Valve (RH2.x) is open which provides some compressor discharge gas to the reheat condenser to further increase the reheat of the evaporator airstream.
