FAN PERFORMANCE — HORIZONTAL DISCHARGE UNITS (cont)
LEGEND
*Standard motor drive range: 685 to 935 rpm. Alternate motor drive
range: 835 to 1085 rpm. High static motor drive range: 830 to
1130 rpm. All other rpms require field-supplied drive.
NOTES:
1.
Boldface
indicates field-supplied drive is required.
2.
indicates high-static motor and drive are required.
3. Maximum usable watts input is 2120 with standard motor, 2615 with
alternate motor, and 4400 for the high-static motor. Maximum
continuous bhp is 2.40 with standard motor, 2.90 with alternate
motor and 5.25 with high-static motor. Extensive motor and electri-
cal 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 prema-
ture motor failure. Unit warranty will not be affected.
4. Values include losses for filters, unit casing, and wet coils. See
page 49 for accessory/FIOP static pressure information.
5. Use of a field-supplied motor may affect wire sizing. Contact your
Carrier representative for details. For additional information on
motor performance, refer to Indoor-Fan Motor Performance table on
page 52.
6. Interpolation is permissible. Do not extrapolate.
