NOTES:
1. Values include losses for filters, unit casing, and wet coils.
2. 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
Table 4.

NOTES:
1. Boldface indicates a field-supplied drive is required. (See Note 4.)
2. Maximum usable watts input is 1000. 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 rat-
ings shown will not result in nuisance tripping or premature motor
failure. Unit warranty will not be affected. For additional information
on motor performance, refer to Table 4.
