Your Bryant Packaged Heat Pump 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 t o maintain and easy to use.

Easy to install:

All Legacy Linet units are field--convertible to horizontal air flow; no special adapter curbs or kits are necessary. Convertible airflow design makes it easy to adjust to unexpected job--site complications. Light er units make easy replacement. Bryant 3--8.5 ton 548J rooftops fit on existing Bryant curbs dating back to 1989. Also, our large control box 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 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:

The newly designed, master terminal board by Bryant puts all your connect ions 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” (51mm) filters standard.

FACTORY OPTIONS AND/OR ACCESSORIES (cont.)

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 re quired.

Economizers are available, installed and tested by the factory, with either enthalpy or dry--bulb temperat ure inputs. There are also models for elect romechanical as well as direct digital controllers. Additional 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

Trust the expe rts. 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.

Non--fused Disconnect

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

Power Exhaust Pressure 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 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

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 c loses when the rooftop stops, stopping unwanted infiltration.

Manual OA Damper

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.

Manual out door air dampers are an econom ical way to bring in ventilation air. The dampers are available in 25% and 50% versions.

FACTORY OPTIONS AND/OR ACCESSORIES (cont.)

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.

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 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. T hese couplings eliminate roof penetration and should be considered for gas lines, main power lines, as well as control power.

Electric Heaters

Bryant offers a full--line of field--installed accessory heaters. The heaters are very easy to use, install and are all pre--engineered and certified.

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 an “average” human ear. A --- weighted measurements for Bryant units 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 t o an outdoor ambient temperature of 25_F(--4_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 and max airflow (cooling mode):

548J

To maintain safe and reliable operation of your rooftop, operate within the c ooling airflow limits. Operating above the max may ca use 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 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 Bryant’s internal unit design, air path, and specially designed motors, the full horsepower (maximum continuous BHP) band, as listed in this manual, can be used with the utmost confidence. There is no need for extra safety factors, as Bryant’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 typically results in very poor part load performance and humidity control.

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 conditioners. 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 tha n 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 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 t o ambient tempe ratures down to --20_F(--29_C) using the recommended accessory Motor master low ambient controller.

SELECTION PROCEDURE (WITH 548J*07 EXAMPLE)

(Selection software by Bryant saves time by performing many of the steps below.)

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) TC

Load

SHC

Load

Outdoor-Air Winter Design Temp 0_F(--18_C) Indoor-Air Winter Design Temp 70_F(21_C) Vertical Supply Air 2100 CFM External Static Pressure 0.66 in.wg Electrical Characteristics 230--3--60

II. Make an initial guess at cooling tons.

Refrig. tons = TC Refrig. tons = 65.0 / 12 = 5.42 tons

In this case, start by looking at t he 548J*07.

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

Table 11 shows that, at the application’s supply air CFM, mixed air and ambient temperatures, the 548J*07 supplies: TC SHC

= 69.0 MBH

Load

= 50.7 MBH.

/ 12 MBH per ton

Load

65.0 MBH

46.0 MBH

45.0 MBH

The require d heating capacity is 45,000 Btuh. Therefore, 20,700 Btuh (45,000 – 24,300) additional electric heat is required.

Determine additional electric heat capacity in kW.

20,700 Btuh

3413 Btuh/kW

=6.1kWofheatrequired.

Enter the Electric Heating Capacities table for 548J*07 at 208/230, 3--phase. The 6.5-kW heater at 230V most closely satisfies the heating required.

6.5 kW x 3413 = 22,185 Btuh

Total unit heating capacity is 46,485 Btuh (22,185 + 24,300).

VI. Calculate RTU Latent Heat Capacity

LC = TC -- SHC LC = 69.0 MBH -- 50.7 MBH = 18.3 MBH

VII. Compare RTU capacities to loads.

Compare the rooftop’s SHC and LC to the building’s Sensible and Latent Heat Loads. See Notes 1 and 2.

VIII. Select factory options (FIOP)

Local code requi res an economizer for any unit with TC larger than 65.0 MBH.

548J

IV. Calculate the building Late nt Heat Load.

LC LC

=TC

Load

= 65.0 MBH -- 46.0 MBH = 19.0 MBH

Load

-- S H C

Load

V. Select electric heat.

Enter the Instantaneous and Integrated Heating Ratings, Table 17 at 2100 cfm. At 70_F(21_C) return indoor air and 0°F(--18_C) air entering outdoor coil, the integrated heating capacity after interpolation, is 24,300 Btuh. (Select integrated heating capacity value since deductions for outdoor-coil frost and defrosting have already been made. No correction is required.)

BHP — Break horsepower FLA — Full load amps HC — Heating Capacities LC — Latent capacity LRA — Lock rotor amp MBH — (1,000) BTUH MCA — Min. circuit ampacity MOCP — Max. over- -- current protection RPM — Revolutions per minute RTU — Rooftop unit SHC — Sensible heat capacity TC — Total capacity

IX. Calculate the total static pressure.

External static pressure 0.66 in. wg Sum of FIOP/Accessory static +0.14 in.

Total Static Pressure 0.80 in. wg

X. Look up the Indoor Fan RPM & BHP.

Table 34 shows, at 2100 CFM & ESP= 0.8, RPM = 1268 & BHP = 1.52

XI. Determine electrical requirements

Table 25 shows the MCA and MOCP of a 548J*07 (without convenience outlet) with 6.5 kW electric heater as:

MCA = 52.3 amps & MOCP = 60 amps Min. Disconnect Size: FLA = 50 & LRA = 199.

NOTES:

1. Selecting a unit with a SHC slightly lower than the SHC often better than oversizing. Slightly lower SHC’s will help control indoor humidity, and prevent temperature swings.

2. If the rooftop’s capacity meets the Sensible Heat Load, but not the Latent H eat Load.

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 may add static pressure losses, as shown in Table 20. Selection software is available, through your salesperson, to help you select the best motor/drive combination for your application.

4. The Fan Performance 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 more information on the performance limits of Bryant motors, see the application data section of this book.

1. In compliance with NEC requirements for multimotor and combination load equipment (refer to NEC Articles 430 and

440), the overcurrent protective device for the unit shall be fuse or HACR breaker. Canadian units may be fuse or circuit breaker.

2. Unbalanced 3-Phase Supply Voltage Never operate a motor where a phase imbalance in supply voltage is greater than 2%. Use the following formula to determine the percentage of voltage imbalance.

% Voltage Imbalance = 100 x

max voltage deviation from average voltage

Example: Supply voltage is 230-3-60

AB = 224V BC = 231V AC = 226V

Average Voltage =

(224 + 231 + 226)

= 227

Determine maximum deviation from average voltage. (AB) 227 – 224 = 3V Maximum deviation is 4V. (BC) 231 – 227 = 4V Determine percent of voltage imbalance.

% Voltage Imbalance = 100 x

= 1.76%

227

This amount of phase imbalance is satisfactory as it is below the maximum allowable 2%.

IMPORTANT: If the supply voltage phase imbalance is more than 2%, contact your local electric utility company immediately.

SEQUENCE OF OPERATION

Cooling, unit without economizer

When thermostat calls for cooling, terminals G and Y1 are energized. The indoor-fan contactor (IFC), reversing valve solenoid (RVS) and compressor contactor are energized and indoor-fan motor, compressor, and outdoor fan starts. The outdoor fan motor runs continuously while unit is cooling.

Heating, unit without economizer

Upon a request for heating from the space thermostat, terminal W1 will be energized with 24V. The IFC, outdoor-fan contactor (OFC), C1, and C2 will be energized. The indoor fan, outdoor fans, and compressor no. 1, and compressor no. 2 are energized and reversing valves are deenergized and switch position.

548J

If the space temperature continues to fall while W1 is energized, W2 will be energized with 24V, and the heater contactor(s) (HC) will be energized, which will energize the electric heater(s).

When the space thermostat is satisfied, W2 will be deenergized first, and the electric heater(s) will be deenergized.

Upon a further rise in space temperature, W1 will be deenergized.

Cooling, unit with EconoMi$er IV

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 to 55_F(10_ to 13_C) mixed-air temperature into the zone. As the mixed-air temperature fluc tuates a bove 55 or below 50_F (13_ to 10_C), the 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 the mixed-air temperature rises above 48_F(9_C).

If optional power exhaust is installed, as the outdoor-air damper opens and closes, the power exhaust fans will be energized and deenergized.

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.

sensors are connected to

level decreases because of the

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

On the initial power to the EconoMi$er IV control, it will

take the damper up to 2

/2minutes before it begins to position itself. Any change in damper position will take up to 30 seconds to initiate. Damper movement from full closed to full open (or vice versa) will take between 1 and 21/2minutes.

If free cooling can be used as det ermined from the appropriate changeover command (switch, dry bulb, enthalpy curve, differential dry bulb, or differential enthalpy), then the control will modulate the dampers open to maintain the mixed-air temperature setpoint at 50_ to 55_F(10_ to 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$er IV damper will be open at maximum position. EconoMi$er IV operation is limited to a single compressor.

Heating, unit with EconoMi$er

When the room temperature calls for heat through terminal W1, the indoor (evaporator) fan contactor (IFC) and heater contactor no. 1 (HC1) are energized and the reversing va lve(s) deenergize and switches position. On units equipped for 2 stages of heat, when additional heat is needed, heater contactor no. 2 is energized through W2. The economizer damper moves to the minimum position. When the thermostat is satisfied, the damper moves to the fully closed position.

Defrost

When the tem perature of the outdoor coil drops below 28_F(--2_C) as sensed by the defrost thermostat (DFT2) and the defrost timer is at the end of a timed period (adjustable at 30, 60, 90 or 120 minutes), reversing valve solenoids (RVS1 and RVS2) are energized and the OFC is deenergized. This switches the position of the reversing valves and shuts off the outdoor fan. The electric heaters (if installed) will be energized.

The unit continues to defrost until the coil temperature as measured by DFT2 reaches 65_F(18_C), or the duration

of defrost c ycle completes a 10-minute period.

During the Defrost mode, if circuit 1 defrosts first, RVS1 will oscillate between Heating and Cooling modes until the Defrost mode is complete.

At the end of the defrost cycle, the electric heaters (if installed) will be deenergized; the reversing valves switch and the outdoor-fan motor will be energized. The unit will now operate in the Heating mode.

If the space thermostat is satisfied during a defrost cycle, the unit will continue in the Defrost mode until the time or temperature constraints are satisfied.

Automatic changeover

When the system selection switch is set at AUTO. position, unit automatically changes from heating operation to cooling operation when the temperature of the c onditioned space rises to the cooling level setting. When the temperature of the conditioned space falls to the heating level setting, unit automatically changes from cooling to heating operation (with a 3°F deadband in between).

Continuous air circulation

Turn unit power on. Set system control at OFF position. Set fan switch at ON position. The indoor-fan contactor is energized through the thermostat switch and the indoor fan runs continuously.

Cycle-LOC™ protection

If unit operati on is interrupted by an open high-pressure switch, low-pressure switch, indoor coil freeze stat, or by compressor internal line-break device (overcurrent or overtemperature), and compressor is calling for either cooling or heating, Cycle-LOC protection device simultaneously locks out uni t and lights a warning light on the thermostat. Restart the unit by manually turning thermostat to OFF and then to ON position. If any of the protective devices opens again, the unit continues to lock out until corrective action is taken.

NOTE: If the unit fails to operate due to compressor over-current condition, restart by manually resetting circuit breakers at the unit. Restart cannot be accomplished at the room thermostat.

Emergency heat

If compressor is inoperative due to a tripped safety device (high or low pressure, indoor coil freeze stat, overcurrent, or overtemperature), the Cycle-LOC device locks out the compressor and lights a warning light on the room thermostat. When the switch is on (thermostat is set to the EM HT position), compressor circuit and outdoor thermostats are bypassed, and the second stage of thermostat energizes the indoor blower and the electric resistance heaters.
