NOTES:
1. Standard low-medium static drive range is 1066 to 1283 rpm. Alternate high-
static drive range is 1332 to 1550. Other rpms require a field-supplied drive.
2. Maximum continuous bhp is 10.2 (208/230 v) or 11.8 (460 v) and the maxi-
mum continuous watts are 9510 (208/230 v) or 11,000 (460 v). 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., EconoMi$erIV) 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 21 for accessory/FIOP static pressure information.
6. Extensive motor and drive testing on these units ensures that the full horse-
power and watts range of the motor can be utilized with confidence. Using
the 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 local
Bryant representative for details.

*The static pressure must be added to external static pressure. The
sum and the evaporator entering-air cfm should then be used in con-
junction with the Fan Performance tables to determine blower rpm and
watts.
