FAN PERFORMANCE — 48/50HG014-028 (Horizontal Supply and Return) (cont)
LEGEND
*For standard motor with standard drive, the drive range is 658 to
808 rpm. For standard motor with alternate drive, the drive range is
794 to 974 rpm. For alternate motor with standard drive, the drive
range is 949 to 1145 rpm. For alternate motor with optional drive, the
drive range is 1126 to 1328 rpm. All other rpms require a field-
supplied drive.
NOTES:
1. Maximum continuous Bhp for the standard motor is 5.75. Maximum
continuous Bhp for the alternate motor is 8.63. The maximum contin-
uous watts for the standard motor is 4290. The maximum continuous
watts for the alternate motor is 6438. Do not adjust motor rpm such
that motor maximum Bhp and/or watts is exceeded at the maximum
operating cfm.
2. Static pressure losses 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 baffles, filters, unit casing, and wet coil
losses.
5. 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 nui-
sance tripping or premature motor failure. Unit warranty will not be
affected. See Evaporator-Fan Motor Specifications table on page 54
for additional information.
6. Use of a field-supplied motor may affect wire sizing. Contact your
Carrier representative for details.
