Table 23 — Fan Rpm at Motor Pulley Settings*

*Approximate fan rpm shown.

†Indicates standard low/medium static drive package.

**Indicates alternate high static-drive package.

††Due to belt and pulley size, pulley cannot be set to this number of

turns open.

NOTE: For speeds not listed above, field-supplied drives are required.

Table 24 — Evaporator-Fan Motor Data

LEGEND

*Extensive motor and electrical testing on these units ensures that the full horsepower (brake kilowatt) range

of the motors can be utilized with confidence. Using the fan motors up to the horsepower (brake kilowatt) rat-
ings 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) effective October 24, 1997.

Table 25 — Evaporator-Fan Motor Efficiency

NOTE: All indoor-fan motors 5 hp and larger meet the minimum effi-
ciency requirements as established by the Energy Policy Act of 1992
(EPACT) effective October 24, 1997.
