Table 27 — Fan Performance, 50TFQ012 — Horizontal Discharge Units; High-Static Motor and Drive*

LEGEND

*Motor drive range: 830 to 1130 rpm. All other rpms require field-

supplied drive.

Refer to General Fan Performance Notes below.

NOTES:

Boldface

indicates field-supplied drive is required.

2. Maximum continuous bhp is 5.25.

GENERAL NOTES FOR FAN PERFORMANCE DATA TABLES

1. Fan performance is based on clean filters and wet coil data.
2. Extensive motor and electrical testing on these units ensures

that the full range of the motor can be utilized with confidence.
Using 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 perfor-
mance Table 9.

3. Values include losses for filters, unit casing, and wet coils. See

Tables 11A and 11B for static pressure 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.
