Step 8 — Install Outdoor Air Hood —

Perform the

following procedure to install the outdoor-air hood:

1. Remove blank panel from return end of unit (hood sec-

tion). Save the screws. See Fig. 15 for shipping location
of components.

2. Hood sides are fastened to sides of outdoor air opening.

Remove the hood sides and save the screws (3 each side).

3. Remove the bracket holding the bottom half of the hood

in the shipping position. Remove the hood bottom half
and filters (or manual dampers on units so equipped)
from outdoor section.
NOTE: On units without economizers, the components
are attached to the unit basepan. To access the compo-
nents, remove the panel below the outdoor air intake
section.

4. Remove inner filter track from shipping position in out-

door section. Position inner filter track so the track is fac-
ing outward from the unit. Install the filter track with
4 screws provided.

5. Apply seal strip (provided) to back flange of both hood

sides where hood side connects to the unit back panel.
See Fig. 16.

6. Apply seal strip (provided) to top flange of both hood

sides where hood sides connect to the hood top panels.
See Fig. 16.

7. Install hood sides to the back panels using the screws from

Step 2. The sloped flanges point outward. The drip edges
of the side panels should face outward as well. The filter
guides should face inward to hold the filters in place. See
Fig. 16.

8. Apply seal strip along the entire length of the bottom

flange of the hood top. See Fig. 16.

9. Install the bottom part of the hood top using 4 screws pro-

vided. See Fig. 16.

10. Remove the packaging from filters (3) and install into the

filter tracks. Slide the filters to the sides then place the last
filter into the center of the filter track.

NOTE: For units with manual dampers, replace the end filters
with the manual dampers. Install the filter in the center
between the manual dampers.

11. Install the filter retainer track along the bottom edge of the

outdoor air hood using 4 screws provided. See Fig. 16.

12. Install top section of the outdoor air hood using 9 screws

provided. See Fig. 16. See Fig. 17 for a picture of the
assembled outdoor air hood.

NOTE: For filter removal, remove the four screws holding the
filter retainer. The filters can then be removed, cleaned, or
replaced. Install the filters by reversing the procedure.
MANUAL DAMPER ASSEMBLY —

For units equipped

with manual dampers, the assembly process is similar to the out-
door air hood for units with economizers. There are two slide
dampers shipped with the unit to allow for manual setting of the
outside air volume. When assembling the hood, place one of the
manual slide dampers in each of the end positions and the re-
maining filter in the center position. The manual dampers can
then be moved to the appropriate position and then locked into
place using the screws mounted in the adjustment slots. See
Fig. 18.
