Table 12 — Fan Performance — 50HJ025
LEGEND
*Standard low-medium static drive range is 1002 to 1151 rpm. Alter-
nate high-static drive range is 1193 to 1369. Other rpms require a
field-supplied drive.
NOTES:
1. Maximum continuous bhp for the standard motor is 9.47 (for
208 and 575-v units) and 10.33 (for 230 and 460-v units). The
maximum continuous watts is 7915 (for 208 and 575-v units)
and 8640 (for 230 and 460-v units). 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., EconoMi$er) 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 Carrier representative for details.
