** Indicates alternate drive package only.

††Indicates high-static motor and drive package.
***Indicates alternate motor and drive package.

Table 7 — Evaporator-Fan Motor Efficiency

NOTE: Convert bhp to watts using the following formula:

Table 8 — Accessory/FIOP Static Pressure* (in. wg)

LEGEND

*The static pressure must be added to external static pressure. The

junction with the Fan Performance tables to determine blower rpm and
watts.
