*The static pressure must be added to external static pressure. The sum and the evaporator entering-air cfm should then
be used in conjunction with the Fan Performance tables to determine blower rpm and watts.
Table 24 — Fan Rpm at Pulley Settings*
*Approximate fan rpm shown.
†Indicates standard drive package.
**Indicates alternate drive package.
††Due to belt and pulley size, pulley cannot be set to this number of turns open.

LEGEND
*Extensive motor and electrical testing on these units ensures that the full
horsepower (brake kilowatt) range of the motors can be utilized with confi-
dence. Using fan motors up to the horsepower (brake kilowatt) ratings shown
in this table will not result in nuisance tripping or premature motor failure.
Unit warranty will not be affected.
NOTE: All indoor-fan motors 5 hp and larger meet the minimum efficiency
requirements as established by the Energy Policy Act of 1992 (EPACT) effec-
tive October 24, 1997.
