*Standard drive range is 590 to 840 rpm. Alternate drive range is 685 to
935 rpm. All other rpms require a field-supplied drive.
NOTES:
1. Boldface indicates field-supplied motor and drive are required.
2. Values include losses for filters, unit casing, and wet coils. See
page 52 for accessory/FIOP static pressure information.
3. Maximum continuous bhp is 2.40 and the maximum continuous
watts are 2120. Extensive motor and electrical testing on these units
ensures that the full range of the motor can be utilized with confi-
dence. Using your fan motors up to the wattage ratings shown will
not result in nuisance tripping or premature motor failure. Unit war-
ranty will not be affected. See Evaporator-Fan Motor Performance
table on page 55 for additional information.
4. Use of a field-supplied motor may affect wire sizing. Contact your
local representative for details.
5. Interpolation is permissible. Do not extrapolate.
