*Low NOx/California compliant units.

OPTION AND ACCESSORY WIRING

*Durablade Economizer was a factory-installed option (FIOP) until 2/15/02, it is currently available only as a field-installed accessory.

†EconoMi$er wiring in Fig. 25 is generic (for units produced from 5/99 – 2/02) with the exception of the way the power exhaust switch is wired.

   Refer to Fig. 28 and 29 for more detailed power exhaust switch information.
**Can be factory-installed or field-installed; wiring is the same for both.
