Refer to page 230 for general Fan Performance Data notes.

 

Bhp — Brake Horsepower

Watts — Input Watts to Motor

*Standard low-medium static drive range is 873 to 1021 rpm. Alternate high-static drive range is 1025 to 1200. Other rpms require a field- supplied drive.

NOTES:

1.Maximum continuous bhp for the standard motor is 6.13. The max- imum continuous watts is 5180. Do not adjust motor rpm such that motor maximum bhp and/or watts is exceeded at the maximum operating cfm. See Evaporator Fan Motor Data tables for more information.

2.Fan performance is identical for horizontal discharge applications using Bryant horizontal adapter curb.
