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
nuisance tripping or premature motor failure. Unit warranty will not
be affected. See Table 6 — Motor Data for Additional information.
3. Use of a field-supplied motor may affect wire sizing. Contact your
Carrier representative for details.

4. Maximum continuous bhp is 1.00 and the maximum continuous
watts are 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 ratings shown
will not result in nuisance tripping or premature motor failure. Unit
warranty will not be affected. See Table 6 — Motor Data for addi-
tional information.
