FAN PERFORMANCE — 558F180-300 UNITS (cont)
LEGEND
*Standard low-medium static drive range is 1066 to 1283 rpm. Alternate high-static drive range
is 1332 to 1550. Other rpms require a field-supplied drive.
NOTES:
1. Maximum continuous bhp is 10.20 (208/230 v) or 11.80 (460 v) and the maximum contin-
uous watts are 9510 (208/230 v) or 11,000 (460 v). 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 146 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.

*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 Fan Performance tables to determine blower rpm and watts.
