Table 10 — Fan Performance — 50TJ028
LEGEND
*Standard low-medium static drive range is 1066 to 1283 rpm. Alter-
nate high-static drive range is 1332 to 1550. Other rpms require a
field-supplied drive.
NOTES:
1. Maximum continuous bhp is 10.2 (208/230, 575 v) or 11.8 (380,
460 v) and the maximum continuous watts are 9510 (208/230,
575 v) or 11,000 (380, 460 v). Do not adjust motor rpm such
that motor maximum bhp and/or watts is exceeded at the maxi-
mum 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 12 for accessory/FIOP static pressure
information.
5. Extensive motor and drive testing on these units ensures that
the full horsepower 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.
