NOTES:

1.Values include losses for filters, unit casing, and wet coils. See Table 7 for accessory/FIOP static pressure information.

2.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 Table 6 — Motor Data for Additional information.

3.Use of a field-supplied motor may affect wire sizing. Contact your Carrier representative for details.

Bhp — Brake Horsepower Input to Fan

FIOP — Factory-Installed Option

Watts — Input Watts to Motor

*Motor drive range is 760 to 1000 rpm. All other rpms require a field- supplied drive.

NOTES:

1.Boldface indicates field-supplied drive is required.

2.Values include losses for filters, unit casing, and wet coils. See Table 7 for accessory/FIOP static pressure information.

3.Maximum continuous bhp is 1.00 and maximum continuous watts are 1000. Extensive motor and electrical testing on these units ensures that the full range of the motor can be utilized with confi- dence. Using your fan motors up to the wattage ratings shown will not result in nuisance tripping or premature motor failure. Unit war- ranty will not be affected. See Table 6 — Motor Data for additional information.

4.Use of a field-supplied motor may affect wire sizing. Contact your Carrier representative for details.

5.Interpolation is permissible. Do not extrapolate.
