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.

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.

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.
