VIII. STEP 8 — INSTALL OUTDOOR-AIR HOOD

The same type of factory-installed hood is used on units with

25% air ventilation and units with an EconoMi$er.

NOTE: The hood top panel, upper and lower filter retainers,

hood drain pan, baffle (300), and filter support bracket are

secured opposite the condenser end of the unit. The screens,

hood side panels, remaining section of filter support bracket,

seal strip, and all other hardware are in a package located

inside the return-air filter access panel (Fig. 19).

1. Attach seal strip to upper filter retainer. See Fig. 20.

2. Assemble hood top panel and side panels, upper filter

retainer, and hood drain pan (Fig. 21).

3. Secure lower filter retainer and long section of filter

support bracket to unit. See Fig. 21. Leave screws

loose on size 300 units.

4. Slide baffle (size 300 unit) behind lower filter

retainer and tighten screws.

5. Loosen sheet metal screws for base unit top panel

located above outdoor-air inlet opening, and remove

screws for hood side panels located on the sides of the

outdoor-air inlet opening.

6. Match notches in hood top panel to unit top panel

screws. Insert hood flange between unit top panel

flange and unit. Tighten screws.

7. Hold hood side panel flanges flat against unit, and

install screws removed in Step 5.

8. Insert outdoor-air inlet screens and spacer in channel

created by lower filter retainer and filter support

bracket.

9. Attach remaining short section of filter support

bracket.

A. Outdoor Air Enthalpy Sensor Installation

Perform the following procedure to install the outdoor air

enthalpy sensor (part no. CROUTENT001A00).

1. Remove the outdoor air temperature sensor cover.

See Fig. 22. Save cover and screws.

2. Disconnect the wiring from the installed outdoor air

temperature sensor. See Fig. 23.

3. Use a

-in. nut driver to remove the 2 screws secur-

ing the outdoor air temperature sensor to the sheet

metal.

4. Mount the outdoor air enthalpy sensor in the outdoor

air temperature sensor location using the screws

removed in Step 3.

5. Connect the outdoor air enthalpy sensor wiring har-

ness to the EconoMi$er control module and sensor.

6. Re-install sensor cover saved from Step 1.

B. Return Air Temperature Sensor or Return Air Enthalpy

Sensor Installation

Perform the following procedure to install the return air

temperature sensor (part no. CRRETTMP001A00) or return

air enthalpy sensor (part no. CRRETENT001A00).

1. Attach the sensor to the mounting bracket using

2 self-tapping

-in. screws provided.

2. Mount the bracket to the inside of the return air

opening flange using a

-in. nut driver and 2 no. 6

sheet metal screws.

NOTE: The sensor must be mounted in an upright position.

3. Feed the sensor wiring through the bushing in

EconoMi$er to secure wires.

4. Route sensor wiring harness from sensor to

EconoMi$er control module. Secure wiring harness to

the original harness using tie wraps.

5. Wire the sensor to the EconoMi$er control module.

See Fig. 24 and 25.
