Your Bryant rooftop unit (RTU) was designed by customers for customers. With “no--strip” screw collars, handled access panels, and more we’ve made your unit easy to install, easy to maintain, easy to use, and easy to love.

Easy to install:

All 558J units are horizontal. No special adapter curbs are necessary. Convertible airflow design makes i t easy to adjust to unexpected job--site complications. Lighter units make easy replacement. Bryant 3--6 ton 558J rooftops fit on existing Bryant curbs. Also, our large control box gives you room to work and room to mount Bryant accessory controls.

Easy to maintain:

Bryant’s easy access handles 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 condenser pressure with panels on. Simply remove the black, composite plug, route your gauge line(s) through the hole, and connect them to the refrigeration service valve(s). Now, you can take refrigeration system pressure readings without affecting the condenser airflow.

Easy to use:

Bryant rooftops have high and low pressure switches, a filter drier, and 2” filters standard. Bryant’s terminal board puts all your connections and troubleshooting points in one 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.

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 eit her enthalpy or dry--bulb temperature inputs. T here are also models for electromechanical as well as direct digital controllers. Additional sensors are available as accessories to optimize the economizers.

levels decrease, and

Smoke Detectors

Trust the experts. Smoke detectors make your application safer and your job easier. Bryant’s 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)

Lower service bills by including a convenience outlet in your specification. Bryant will install this service feature at our factory, powered. Provides a convenient, 15 amp, 115v GFCI receptacle.

Non--fused Disconnect

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

Barometric Relief

Gravity controlled, barometric relief equalizes building pressure and ambient air pressures. This can be a cast effective solution to prevent building pressurization.

Power Exhaust with Barometric Relief.

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

RTU--MP, Multi--protocol Controller

Connect the rooftop to an existing BAS without needing complicated translators or adapter modules using the RTU--MP controller. This new controller speaks the 4 most common building automation 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--cycling in the event of some other failure, prevents the compressor from restarting for 30 seconds after stopping. Not required with PC, RTU--MP, or authorized commercial thermostats.

Filter or Fan Status Switches

Use these differential pressure switches to detect a filter clog or indoor fan motor failure. When used in conjunction with a compatible unit controller/thermostat, the switches will activate an alarm to warn the appropriate personnel.

Motorized 2--Position Damper

Bryant’s new, 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 t he rooftop stops, stopping unwanted infiltration.

Manual OA Damper

Manual outdoor air dampers are an economical way to bring in ventilation air.

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 device 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

Bryant’s winter start kit extends the low ambient limit of your rooftop to 25_F(--9_C). The kit bypasses the low pressure switch, preventing nui sance tripping of the low pressure switch. Other low ambient precautions may still be prudent.

UV--C Lights

Bryant’s commercial rooftop ultra--violet germicidal lamps are designed to kill odor causing mold and fungus that may develop in the cool and damp evaporator section of an HVAC unit. The high output, low tempe rature germicidal lamps are installed in the evaporator section of the HVAC unit, and shine dire ctly on the evaporator coil

Page 7

and condensate pan. The short wave length ultra--violet band light inhibits and kills mold, fungus, and microbial growth.

Alternate Motors and Drives

Some applications need larger horsepower motors, some need more airflow, and some need both. Regardless of the case, Bryant has a factory installed 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 either an accessory or 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 a nd should be considered for gas lines, main power lines, as well as control power.

Electric Heaters

Bryant offers a full--line of accessory heaters. The heaters are very easy to use and install.

NOTES:

1. Outdoor sound data is measure in accordance with ARI standard 270-- -95.

2. Measurements are expressed in terms of sound power. Do not compare these values to sound pressure values because sound pressure accounts for specific environmental factors which do not match individual applications. Sound power values are independent of the environment and therefore more accurate.

3. A ---weighted sound ratings filter out very high and very low frequencies, to better approximate the response of “average” human ear. Bryant’s A --- weighted measurements are taken in accordance with 270--- 95.

APPLICATION DATA

Min operating ambient temp (cooling):

In mechanical cooling mode, your Bryant rooftop can safely operate down to an outdoor ambient temperature of 25_F(--4_C), with an accessory winter start kit. 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 and max airflow (cooling mode):

558J

To maintain safe and reliable operation of your rooftop, operate within the cooling airflow limits. 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.

Airflow:

All units are draw--though in cooling 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 the ir 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 Bryant’s internal unit design, air path, and specially designed motors, the full horsepower (maximum continuous BHP) band, as listed in Table 5, can be used with the utmost confidence. There is no need for extra safety factors, as Brya nt’s motors are designed and rigorously tested to use the entire, listed BHP range without either nuisance tripping or premature motor failure.

Sizing a rooftop

Bigger isn’t necessarily better. While an air conditioner needs to have enough capacity to meet the load, it doesn’t need excess capacity. In fact, having excess capacity is often bad.

Using higher design temperatures than ASHRAE recommends for your location, adding “safety factors” to the calculated load, and rounding up to the next largest unit, are all signs of oversizing air conditi oners. Oversizing can cause short--cycling, and short cycling leads to poor humidity control, reduced efficiency, higher utility bills, drastic indoor temperature swings, excessive noise, and increased wear and tear on the air conditioner.

Rather than oversizing an air conditioner, wise contractors and engineers “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.

Low ambient applications

When equipped with a Bryant economizer, your rooftop unit can 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 condi tions, unless the outdoor air is excessively humid or contaminated, economizer--based “free cooling” is the preferred l ess 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 rooft op c an operate to ambient temperatures down to --40_F(--40_C) using the recommended accessory Motormaster low ambient controller.

Winter start

Bryant’s winter start kit extends the low ambient limit of your rooftop to 25_F(--4_C). The kit bypasses the low pressure switch, preventing nui sance tripping of the low pressure switch. Other low ambient precautions may still be prudent.

SELECTION PROCEDURE (WITH 558J*07 EXAMPLE)

I. Determine cooling and heating loads.

Given: Mixed Air Drybulb 80_F(27_C) Mixed Air Wetbulb 67_F(19_C) Ambient Drybulb 95_F(35_C) THC

Load

SHC

Load

Supply Air 2100 CFM Heating Load 85.0 MBH External Static Pressure 0.67 in.wg Electrical Characteristics 230--3--60

II. Make an initial guess at cooling tons.

Refrig. tons = THC Refrig. tons = 69.0 / 12 = 5. 75 tons

In this case, start by looking at the 558J*07.

/ 12 MBH per ton

Load

69.0 MBH

51.0 MBH

V. Calculate RTU Latent Heat Capacity

LHC = THC -- SHC LHC = 73.7 MBH -- 54.3 MBH = 19.4 MBH

VI. Compare RTU capacities to loads.

Compare the rooftop’s SHC and LHC to the building’s Sensible and Latent Heat Loads.

VII. Select factory options (FIOP)

Local code requires an economize r for any unit with THC less than 65.0 MBH.

VIII. Calculate the total static pressure.

External static pressure 0.67 in. wg Sum of FIOP/Accessory static +0.13 in.

Total Static Pressure 0.80 in. wg

558J

III. Look up the rooftop’s THC and SHC.

Table 11 shows that, at the application’s supply air CFM, mixed air and ambient temperatures, the 558J*07 supplies: THC SHC

= 73.7 MBH

Load

= 54.3 MBH.

IV. Calculate the building Latent Heat Load.

Load

IX. Look up the Indoor Fan RPM & BHP.

Table 26 shows, at 2100 CFM & ESP= 0.8, RPM = 1268 & BHP = 1.52

X. Convert BHP (Step VIII) into Fan Motor Heat.

Fan Motor Heat = 2.546* BHP/Motor Eff.

Fan Motor Heat = 4.8 MBH

XI. Determine electrical requirements

Table 32 shows the MCA and MOCP of a 558J*07 (without convenience outlet) as:

MCA = 32.8 amps & MOCP = 50 amps Min. Disconnect Size: FLA = 32 & LRA = 72.

NOTES:

1. Bryant’s selection software saves time by performing many of the steps above. Contact your Bryant sales representative for assistance.

2. Selecting a unit with a SHC slightly lower than the SHC SHC’s will help control indoor humidity, and prevent temperature swings.

3. Indoor Fan Motor efficiency is available in Table 13---26. Use the decimal form in the equation eg. 80% =.8.

General fan performance notes:

1. Interpolation is permissible. Do not extrapolate.

2. External static pressure is the static 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, unit casing, and wet coils. Factory options and accessories

558J

may add static pressure losses, as shown in Table 12. Selection software is available, through your salesperson, to help you select the best motor/drive combination for your application.

4. The Fan Performa nce tables offer motor/drive recommendations. In cases when two motor/drive combinations would work, Bryant recommended the l ower horsepower option.

SEQUENCE OF OPERATION

General

The sequence below describes the sequence of operation for an electro--mechanical unit wit h and without a factory installed EconoMi$er IV (called “economizer” in this sequence). For information 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 fan to start. If the unit has 2 stage s of cooling, the

558J

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--an motor runs continuously while unit is cooling.

Heating

NOTE: The 558J is sold as cooling only. If electric

heaters are required, use only factory--approved e lectric heaters. They will operate as described below.

Units have either 1 or 2 stages of electric heat. When the thermostat calls for heating, power is applied to the W1 terminal at the unit. The unit control will energize the indoor fan contactor and the first stage of electric heat. On units with two-- stage heating, when additional heating is required, the second stage of electric heat (if equipped) will be energized when power is applied at the W2 terminal on the unit.

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 dam per 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 fluctuates 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--air temperature continues to fall, the outdoor--air damper will close. Control returns to normal once t he mixed--air 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 CO2 sensors are connected to the EconoMi$er IV control, a demand controlled ventilation strategy will begin to operate. As the CO2 level in the zone increases above the CO2 set point, the minimum position of the damper will be increased proportionally. As the CO2 level decreases because of the increase in fresh air, the outdoor--air damper will be proportionally closed. For E conoMi$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$er IV control is in the occupied mode and a call for cooling exists (Y1 on the thermostat), the control will first check for indoor fan operation. If the fan is not on, then cooling will not be activated. If the fan is on, then the control will open the EconoMi$er IV damper to the minimum position.

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

Heating

The sequence of operat ion 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.
