Table 9 — Fan Performance — 50HJ015 (With Standard Indoor Fan Motor)
LEGEND
*Standard low-medium static drive range is 834 to 1064 rpm (for
208/230 and 460-v units) or 1105 to 1321 rpm (for 575-v units).
Alternate high-static drive range is 1161 to 1426 (for 208/230 and
460-v units). The alternate high-static drive range is not available
for 575-v units. Other rpms require a field-supplied drive.
NOTES:
1. Maximum continuous bhp for the standard motor is 3.13 (for
208/230 and 460-v units) or 3.38 (for 575-v units). The maxi-
mum continuous watts is 2700 (for 208/230 and 460-v units) or
3065 (for 575-v units). Do not adjust motor rpm such that motor
maximum bhp and/or watts is exceeded at the maximum oper-
ating 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.
