Extensive motor and electrical testing on the Weathermaker I units
ensures that the full power range of the motor can be utilized with
confidence. Using the fan motors up to the power ratings shown
will not result in nuisance tripping or premature motor failure. Unit
warranty will not be affected.
4. Use of field-supplied motor may affect wire sizing. Contact
Carrier representative to verify.
5. Values include losses for filters, unit casings, and wet coils.
6. Motor drive range is 622 to 882 rpm (10.30 to 14.70 r/s) on the
50LJQ008 and 692 to 896 rpm (11.50 to 15.00 r/s) on the 50LJQ012.
All other rpms (r/s) will require a field-supplied drive.
