*Standard low-medium static drive range is 910 to 1095 rpm. Alternate high-static drive range is 1069 to 1287. Other rpms require a field-supplied drive.

NOTES:

1.Maximum continuous bhp for the standard motor is 6.13. The maximum continuous watts is 5180. Do not adjust motor rpm such that motor maximum bhp and/or watts is exceeded at the maximum operating cfm.

2.See below for general fan performance notes.

GENERAL FAN PERFORMANCE NOTES

NOTES:

1.Values include losses for filters, unit casing, and wet coils. See below for accessory/factory-installed option static pressure information.

2.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. See Evaporator-Fan Motor Performance table on page 163 for additional information.

3.Use of a field-supplied motor may affect wire sizing. Contact your Bryant representative for details.

4.Interpolation is permissible. Do not extrapolate.

NOTES:

FIOP — Factory-Installed Option

1.

Heaters are rated at 240 v and 480 v.

2.

The factory assembled horizontal adapter substantially improves fan

 

 

 

performance.

 

3.

The static pressure must be added to external static pressure. The sum and

 

 

the evaporator entering-air cfm should then be used in conjunction with the

Another significant characteristic of these units is their excellent Seasonal Energy Efficiency Ratio (SEER) ratings. The 551B boasts a SEER rating of up to 16, while the 551C takes it even further with ratings exceeding 20. This efficiency not only translates to lower energy bills for homeowners but also contributes to a reduced carbon footprint, making these units environmentally friendly options.

Both models are also designed to operate with eco-friendly refrigerants, aligning with modern energy standards and regulations aimed at reducing greenhouse gas emissions.

In summary, the Bryant 551B and 551C are exemplary choices for homeowners looking for reliable, efficient, and high-performing air conditioning solutions. With features such as two-stage and variable-speed compressors, advanced smart technology, and robust construction, these models stand out in the competitive HVAC market. They promise a comfortable indoor environment along with significant energy savings, making them a wise investment for the future.
