Bhp — Brake Horsepower Input to Fan
FIOP — Factory-Installed Option
Watts — Input Watts to Motor
NOTES:
1. Boldface indicates field-supplied drive is required. (See Note 2.)
2. Factory-shipped motor drive range is 1201 to 1462 rpm. Other rpms
require a field-supplied drive.
3. Maximum continuous bhp is 3.45 and maximum continuous watts
are 3065. 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 and watts range of the motor can be utilized with confi-
dence. Using your fan motors up to the watts or bhp rating shown will
not result in nuisance tripping or premature motor failure. Unit war-
ranty 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.
