11.Install the complete hood assembly on the unit and secure using the screws provided.

NOTE: If optional power exhaust is being installed, complete installation of power exhaust at this time. See Fig. 32 for wiring.

12.Remove the indoor fan motor access panel.

13.Mount the supply air temperature sensor to the lower left portion of the indoor blower housing with the two

(2)screws provided (see Fig. 33). Connect the violet and pink wires to the corresponding connections on the supply air temperature sensor. Replace the indoor fan motor access panel.

CO2 Control Set Up

If a CO2 sensor is not being used, proceed to the next section. If a CO2 sensor is being used, perform the following:

1.Determine the value at which you want the minimum position of the dampers to begin opening to allow a greater amount of outdoor air to enter. The range is 800 to 1,400 ppm.

2.Locate the CO2 SP (PPM) potentiometer and adjust to the desired set point. See Fig. 34.
