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 continuous 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 Table 12
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 Table 14 for Evaporator-
Fan Motor Performance on page 24 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.
Table 12 — Accessory/FIOP Static Pressure (in. wg)* — 558F180-300
LEGEND
*The static pressure must be added to external static pressure. The
sum and the evaporator entering-air cfm should then be used in con-
junction with the Fan Performance tables to determine blower rpm and
watts.
