NOTES:
1. Boldface indicates field-supplied drive is required. (See Note 3.)
2. indicates additional capability of 460-v motor.
3. Factory-shipped motor drive range is 1323 to 1579 rpm. Other rpms
require a field-supplied drive.
4. Maximum continuous bhp is 10.26 (208/230, 575 v) or 11.80 (460 v)
and maximum continuous watts are 9510 (208/230, 575 v) or
11,000 (460 v). Do not adjust motor rpm such that motor maximum
bhp and/or watts is exceeded at the maximum operating cfm.
5. Static pressure losses (i.e., economizer) must be added to external
static pressure before entering Air Delivery table.
NOTE: The 389210-201 high static regain adapter accessory may
be used to provide horizontal supply/return.

6. Interpolation is permissible. Do not extrapolate.
7. Fan performance is based on wet coils, clean filters, and
casing losses. See page 47 for accessory/FIOP static pressure
information.
8. Extensive motor and drive testing on these units ensures that the
full horsepower and watts range of the motor can be utilized with
confidence. Using 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.
9. Minimum allowable cfm is 280 cfm/ton in cooling.
10. Use of a field-supplied motor may affect wire sizing. Contact your
local representative for details. For additional information on motor
performance, refer to Evaporator-Fan Motor Performance table on
page 62.
NOTE: The 389210-201 horizontal supply/return adapter accessory
improves 559F180-300 fan performance by increasing external
static pressure by amount shown above.
