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 maxi- mum 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.Static pressure losses (i.e., economizer) must be added to external static pressure before entering Fan Performance table.

3.Interpolation is permissible. Do not extrapolate.

4.Fan performance is based on wet coils, clean filters, and casing losses. See Table 13 for accessory/FIOP static pressure information.

5.Extensive motor and drive testing on these units ensures that the full bhp and watts range of the motor can be utilized with confidence. Using your fan motors up to the watts or bhp rating shown will not result in nuisance tripping or premature motor failure. Unit warranty will not be affected.

6.Use of a field-supplied motor may affect wiring size. Contact your Bryant representative for details.
