NOTES:
1. Boldface indicates field-supplied drive required. (See Note 4.)
2. indicates field-supplied motor and drive required.
3. indicates maximum usable bhp/watts.
4. Standard motor drive range: 1070 to 1460 rpm. All other rpms require a field-
supplied drive.
5. Values include losses for filters, unit casing, and wet coils.
6. Maximum continuous bhp is 2.4 and maximum continuous watts are 2120. Ex-
tensive 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 watt-
age ratings shown will not result in nuisance tripping or premature motor fail-
ure. Unit warranty will not be affected. See Evaporator-Fan Motor Performance
table on page 60 for additional information.
7. Use of a field-supplied motor may affect wire sizing. Contact your local repre-
sentative to verify.
8. Interpolation is permissible. Do not extrapolate.
9. Minimum allowable cfm is 300 cfm/ton.
