*Extensive motor and electrical testing on these units ensures that the full horsepower and watts range
of the motors can be utilized with confidence. Using your fan motors up to the ratings shown in this
table will not result in nuisance tripping or premature motor failure. Unit warranty will not be affected.
Tabl e 10 — 580D090 Air Delivery, Vertical Discharge Units
NOTES:
1.
Boldface
indicates a field-supplied drive is required. (See Note 8.)
2. indicates an alternate drive is required.
3. indicates a field-supplied motor and drive are required.
4. indicates maximum usable watts of a factory-supplied motor.
5. Maximum usable watts input is 2120. 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 wattage ratings shown will not
result in nuisance tripping or premature motor failure. Unit warranty will not be
affected. For additional information on motor performance, refer to Table 9.
6. Values include losses for filters, unit casing, and wet coils.
7. Use of a field-supplied motor may affect wire sizing. Contact your representa-
tive to verify.
8. Standard motor drive range: 590 to 840 rpm. Alternate motor drive range:
685 to 935 rpm. All other rpms require field-supplied drive.
9. To convert watts to bhp:
Motor efficiency = .80
