NOTES:
1. Field-supplied motor required.
2. Maximum continuous bhp for the standard motor is 3.13 (for 208/230 and
460-v units) or 3.38 (for 575-v units). The maximum continuous watts is
2700 (for 208/230 and 460-v units) or 3065 (for 575-v units). Do not adjust
motor rpm such that motor maximum bhp and/or watts is exceeded at the
maximum operating cfm. See Evaporator Fan Motor Data tables for more
information.
3. Fan performance is identical for horizontal discharge applications using
Bryant horizontal adapter curb.
