Bhp — Brake Horsepower Input to Fan
Watts — Input Watts to Motor
NOTES:
1. Boldface indicates field-supplied drive required. (See Note 6.)
2. indicates alternate motor and/or drive required.
3. indicates field-supplied motor and drive required.
4. indicates maximum usable bhp/watts of standard motor and drive.
5. indicates maximum usable bhp/watts of alternate motor and/or drive.
6. Standard drive range is 860 to 1080 rpm. Alternate drive range is 900 to
1260 rpm. All other rpms require a field-supplied drive.
7. Values include losses for filters, unit casing, and wet coils.
8. Maximum continuous bhp is 4.20 for the standard motor and 5.25 for the al-
ternate motor. Maximum continuous watts are 3775 for the standard motor
and 4400 for the alternate motor. Extensive motor and electrical testing on
these units ensures that the full range of the motor can be utilized with con-
fidence. 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 af-
fected. See Evaporator-Fan Motor Performance table on page 60 for addi-
tional information.
9. Use of a field-supplied motor may affect wire sizing. Contact your local rep-
resentative to verify.
10. Interpolation is permissible. Do not extrapolate.
11. Minimum allowable cfm is 300 cfm/ton.
NOTE: FAN PERFORMANCE DATA TABLES FOR 180-300 UNITS ARE ON PAGES 46-48.
