NOTES:
1. Standard low-medium static drive range is 891 to 1179 rpm. Alter-
nate high-static drive range is 1227 to 1550. Other rpms require a
field-supplied drive.
2. Maximum continuous bhp is 4.25 and the maximum continuous watts
are 3775. Do not adjust motor rpm such that motor maximum bhp
and/or watts is exceeded at the maximum operating cfm.
3. Static pressure losses (i.e., economizer) must be added to external
static pressure before entering Fan Performance table.
4. Interpolation is permissible. Do not extrapolate.
5. Fan performance is based on wet coils, clean filters, and
casing losses. See Table 8 for accessory/FIOP static pressure
information.
6. Extensive motor and drive testing on these units ensures that the full
horsepower and watts range of the motor can be utilized with confi-
dence. 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.
7. Use of a field-supplied motor may affect wiring size. Contact your
Bryant representative for details.
