6.Replace horizontal return duct cover panel. Screw in place ensuring all seams are air and watertight.

7.Install the 2 angle filter brackets to the right and left hood side panels respectively with the #10 screws provided. See Fig. 25.

8.Assemble hood according to Fig. 26 screwing together with provided #10 sheet metal screws.

9.Install assembled hood over the economizer opening in the replacement return chamber panel. See Fig. 27. Screw in place through pre-punched holes. Make sure all seams are air and watertight.

NOTE: The two wires that connect to the outside air temperature sensor (OAT) should remain accessible.

10.Connect the outside air temperature sensor (OAT) to the economizer per wiring diagram.

11.Open the filter clips on the inside of the hood top. Insert the aluminum filter into the hood and close the clips to hold in place. See Fig. 28.

12.To replace 12 x 20 x1 (304.8mm x 508mm x 25.4mm) air filters, open the filter access door (horizontal return duct cover panel), remove old filters and install new disposable filters in filter rack. See Table 13 for filter part number.

NOTE: The economizer control settings and the filters are accessible through the filter access door.

13.Economizer controls are set to a standard factory setting. Nevertheless, you can adjust these settings through the filter access door. Review the settings in the Operation section:

(2.) The standard economizer controller has a factory setting of “C” for the outdoor air temperature changeover and 63_F (17_C) for the supply air (mixed air) temperature sensor. The outdoor air temperature changeover setting is adjusted on the sensor by setting the dip switches on the sensor. The ABCD potentiometer on the economizer control should be set to the “D” position.

(3.) The low ambient compressor lockout switch setting is fixed at 42_F (5.6_C).

(4.) The minimum position for the outdoor air damper can be configured at the controller. When not using a CO2 sensor, the DCV Max potentiometer must be completely closed (CCW) for the Minimum Posi- tion potentiometer to function correctly.

(5.) Settings for the optional outdoor enthalpy sensor, indoor enthalpy sensor, and CO2 sensor can also be configured at the controller.

14.Replace the filter access panel. Screw in place ensuring all seams are air and watertight.

15.Install all economizer accessories then power HVAC unit and test cycle economizer.
