NOTES:
1. Boldface indicates a field-supplied drive is required. (See Note 7.)
2.
indicates field-supplied motor and drive are required.
3.
indicates maximum usable bhp/watts.
4. Maximum usable watts input is 2120 and maximum continuous bhp
is 2.40. 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. For additional information on motor performance, refer to
Evaporator-Fan Motor Performance table on page 62.
5. Values include losses for filters, unit casing, and wet coils. See
page 47 for accessory/FIOP static pressure information.
6. Use of a field-supplied motor may affect wire sizing. Contact your lo-
cal representative for details.
7. Standard motor drive range: 1070 to 1460 rpm. All other rpms re-
quire field-supplied drive.
8. Interpolation is permissible. Do not extrapolate.
9. Minimum allowable cfm is 300 cfm/ton.
