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 685 to 935 rpm. Alternate drive range is 835 to
1085 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 2.4 for the standard motor and 2.9 for the alter-
nate motor. Maximum continuous watts are 2120 for the standard motor and
2615 for the alternate motor. 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 nui-
sance tripping or premature motor failure. Unit warranty will not be affected.
See Evaporator-Fan Motor Performance table on page 60 for additional
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.
