Watts — Input Watts to Motor
NOTES:
1. Boldface indicates field-supplied drive is required. (See Note 2.)
2. Factory-shipped motor drive range is 1047 to 1251 rpm. Other rpms
require a field-supplied drive.
3. Maximum continuous bhp is 5.90 and maximum continuous watts
are 5180. Do not adjust motor rpm such that motor maximum bhp
and/or watts is exceeded at the maximum operating cfm.
4. Static pressure losses (i.e., economizer) must be added to external
static pressure before entering Air Delivery table. See page 47 for
accessory/FIOP static pressure information.
5. Interpolation is permissible. Do not extrapolate.
6. Fan performance is based on wet coils, clean filters, and casing
losses.
7. Extensive motor and drive testing on these units ensures that the full
horsepower range of the motor can be utilized with confidence. Us-
ing your fan motors up to the watts or bhp rating shown will not result
in nuisance tripping or premature motor failure. Unit warranty will not
be affected.
8. Minimum allowable cfm is 300 cfm/ton.
9. Use of a field-supplied motor may affect wire sizing. Contact your lo-
cal representative for details. For additional information on motor
performance, refer to Evaporator-Fan Motor Performance table on
page 62.
