Table 21 — Fan Performance, 48TF008 — Horizontal Discharge Units (English)
LEGEND
NOTES:
1.
Boldface
indicates field-supplied drive required. (See Note 5.)
2.
indicates field-supplied motor and drive are required.
3. Values include losses for filters, unit casing, and wet coils.
4. Use of a field-supplied motor may affect wire sizing. Contact
your Carrier representative to verify.
5. Standard drive range is 492 to 700 rpm. All other rpms require
a field-supplied drive.
6. Maximum continuous bhp is 2.4. Extensive motor and electrical
testing on these units ensures that the full range of the motor
can be utilized with confidence. Using the fan motors up to the
ratings shown will not result in nuisance tripping or premature
motor failure. Unit warranty will not be affected.
7. Interpolation is permissible. Do not extrapolate.
