inch). Screw the EconoMi$er X to the unit along
both side flanges and bottom flange. See Fig. 3.

sor from its shipping location to its operating position;
see Fig. 1.
7. If the EconoMi$er X assembly will be operating with an
enthalpy outside air sensor, remove the factory-installed
HH79AH001 dry bulb sensor from the front face of the
economizer (see Fig. 1) and install the accessory
enthalpy sensor HH57AC081 in the same location as the
dry bulb sensor. Connect the 2-wire gray harness with
plug from the EconoMi$er X assembly to the enthalpy
sensor. See wiring diagrams on pages 9 and 12. Refer to

Enthalpy Sensor” on page 13 for more details on
