Bhp — Brake Horsepower Input to Fan

Watts — Input Watts to Motor

NOTES:

1.Boldface indicates field-supplied or alternate (as appropriate) drive is required. (See Note 7.)

2. indicates alternate motor and drive are required.

3. indicates field-supplied motor and drive are required.

4.Maximum usable watts input is 2120 with standard motor and 2615 with alternate motor. Maximum continuous bhp is 2.40 with

standard motor and 2.90 with alternate motor. Extensive motor and electrical testing on these units ensures that the full range of the motor can be utilized with confidence. Using your fan motors up to the wattage ratings shown will not result in nuisance tripping or premature motor failure. Unit warranty will not be affected.

5.Values include losses for filters, unit casing, and wet coils.

6.Use of a field-supplied motor may affect wire sizing. Contact your representative to verify.

7.Standard motor drive range: 685 to 935 rpm. Alternate motor drive

range: 835 to 1085 rpm. All other rpms require field-supplied drive.

8.Interpolation is permissible. Do not extrapolate.

548D specifications

The Bryant 548D heat pump stands out in the HVAC market for its robust performance, energy efficiency, and advanced technology. Known for its reliability, this particular model is designed to provide optimal heating and cooling for both residential and light commercial applications.

One of the standout features of the Bryant 548D is its variable-speed compressor, which allows for precise temperature control and enhances comfort levels in any environment. This technology enables the 548D to operate efficiently at different speeds, adjusting its output based on the heating or cooling demand. As a result, homeowners can enjoy consistent temperature regulation without the wide fluctuations typical of single-stage systems.

In addition to the variable-speed compressor, the Bryant 548D utilizes advanced refrigerant technology. It employs the environmentally friendly Puron refrigerant, which not only improves the unit's efficiency but also reduces its carbon footprint. This makes the 548D a sustainable choice for those looking to minimize their environmental impact while still enjoying superior heating and cooling performance.

Another key characteristic of the Bryant 548D is its impressive energy efficiency rating, often exceeding the minimum requirements set by the Department of Energy. With a high Seasonal Energy Efficiency Ratio (SEER) for cooling in warmer months and an excellent Heating Seasonal Performance Factor (HSPF), the 548D minimizes energy consumption while maximizing comfort.

The 548D also features Quiet Operation technology, ensuring that the system runs quietly in the background without disrupting daily activities. This is particularly beneficial for light commercial spaces or homes where noise can be a concern. The sleek design and compact size make the unit easy to install in various settings without occupying excessive space.

Furthermore, Bryant incorporates advanced smart technology within the 548D model. The system can be integrated with smart thermostats, allowing users to monitor and control their heating and cooling settings remotely. This feature not only enhances convenience but also enables homeowners to program their systems for maximum efficiency.

In conclusion, the Bryant 548D heat pump is an exceptional choice for those seeking a reliable, efficient, and technologically advanced heating and cooling solution. Its combination of variable-speed compression, eco-friendly refrigerant, high energy efficiency, and quiet operation positions it well in the competitive HVAC market, making it a top choice for both residential and light commercial applications. By investing in the Bryant 548D, consumers can enjoy superior comfort and lower energy bills year-round.
