FAN PERFORMANCE — VERTICAL DISCHARGE UNITS (cont)
LEGEND
*Motor drive range: 860 to 1080 rpm. All other rpms require field-
supplied drive.
NOTES:
1.
Boldface
indicates field-supplied drive is required.
2.
indicates field-supplied motor and drive are required.
3. Values include losses for filters, unit casings, and wet coils. See
page 49 for accessory/FIOP static pressure information.
4. Maximum continuous bhp is 3.7 and the maximum continuous
watts are 3313. 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. See Indoor-Fan Motor Performance
table on page 52 for additional information.
5. Use of a field-supplied motor may affect wire sizing. Contact your
Carrier representative for details.
6. Interpolation is permissible. Do not extrapolate.
