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 4.2 for the standard motor and 5.25 for the al-
ternate motor. The maximum continuous watts are 3775 for the standard mo-
tor 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.
