NOTES:
1. Values include losses for filters, unit casing, and wet coils.
2. 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 nuisance tripping or premature motor
failure. Unit warranty will not be affected. See Evaporator-Fan Motor Perfor-
mance table on page 60 for additional information.
3. Use of a field-supplied motor may affect wire sizing. Contact your local repre-
sentative to verify.
4. Minimum allowable cfm is 300 cfm/ton.

NOTES:
1. Boldface indicates field-supplied drive is required. (See Note 4.)
2. indicates field-supplied motor and drive required.
3. indicates maximum usable bhp/watts.
4. Alternate motor drive range is 835 to 1185 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 1.0, and the maximum continuous watts are 1000.
