FAN PERFORMANCE (ENGLISH) — VERTICAL DISCHARGE UNITS (cont)

LEGEND

NOTES:

1. Boldface

indicates field-supplied drive required (see Note 3).

2.

indicates field-supplied motor and drive required.

3. Factory-shipped drive range is 690 to 900 rpm. Other rpms may require a

field-supplied drive.

4. Values include losses for filters, unit casing, and wet coils.
5. 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

Evaporator-Fan Motor Performance table on page 30 for additional
information.

6. Use of a field-supplied motor may affect wire sizing. Contact your Carrier

representative to verify.

7. To convert Watts to Bhp:

Motor Efficiency: .83

Maximum Continuous Watts: 2120

8. Interpolation is permissible. Do not extrapolate.
9. Static pressure losses (i.e., economizer, electric heater) must be added to

external static pressure before entering Fan Performance table.
