PERFORMANCE DATA (cont)
FAN PERFORMANCE — VERTICAL DISCHARGE UNITS
LEGEND
NOTES:
1.
Boldface
indicates field-supplied drive required. (See Note 2.)
2. Motor drive range is 760 to 1090 rpm for standard motor; 1075 to 1455 rpm
for high-static motor. All other rpms require a field-supplied drive.
3. Values include losses for filters, unit casing, and wet coils. See page 40 for
accessory/FIOP static pressure information.
4. Maximum continuous bhp is 1.20 for standard motor, 2.40 for high-static
motor. Extensive motor and electrical testing on these units ensures that the
full range of the motor can be utilized with confidence. Using your fan motors
up to the ratings shown will not result in nuisance tripping or premature
motor failure. Unit warranty will not be affected. See Evaporator-Fan Motor
Data tables on pages 41 and 42 for additional information.
5. Use of a field-supplied motor may affect wire sizing. Contact your Bryant
representative to verify.
6. Interpolation is permissible. Do not extrapolate.
