9. Remove the indoor-fan motor access panel. (See Fig. 2.)
10. Install the supply air temperature sensor (SAT). The sensor
looks like an eyelet terminal with 2 attached wires, and is
shipped in the economizer hardware bag. The sensor is
located on the “crimped” end and is sealed for moisture.
Mount the SAT to the indoor blower housing. (See Fig. 8.)
Use the provided screw to secure in place. Attach the PINK
and VIOLET wires in the unit to the sensor.
11. Replace the indoor-fan motor access panel.
12. Install the bottom panel with the relief damper attached on the
unit. (See Fig. 9.) Screw panel in place.
NOTE: Remove the bottom screw holding the relief blade closed.
13. Install the upper end economizer panel over the economizer's
outside air damper, and above the bottom panel. Screw panel
in place and screw panel into economizer in two places. (See
Fig. 9.)
14. Assemble the outside air hood per Fig. 10 -12 (see Fig. 10 for
hood component locations):
a. Install filters supports (Item #1) to the upper end panel
using the screws provided.
b. Install each deflector (Item #8) on to each filter support
(Item #1) using the screws provided.
c. Apply seal strip to mating flanges on side plates of hood
(Items #4 and #5).
d. Secure side panels (Items #4 and #5) to upper panel
using the screws provided.
e. Apply seal strip to mating flange of the hood (see
Fig. 10).
f. Secure hood top (Item #3) to upper panel using the
screws provided. (On 44 in. chassis, remove the screws
from across top cover of unit. The rear flange of hood
top will slide behind unit top over flange.)
g. Secure side retainers (Item #6) to side panels (Items #4
and #5) using the screws provided, screwing from
outside of the hood.
h. Secure each central retainer (Item #2) to the hood top
(Item #3). Then align central retainers to holes located
on filter support (Item #1), so central retainer is perpen-
dicular to hood and each filter support. Secure using
screws provided.
i. Apply seal strip to top diverters (Item #7).
j. Secure top diverters (Item #7) to hood top (Item #3).
k. Install outdoor air screens by sliding them into each of
the four spaces created by the hood, filter support and
central retainers. To do so, first insert the air screens into
pocket created at the end of hood (Item #3), then fully
put the air screen into place, then slide them back into
pocket created in the filter support (Item #1). Repeat this
for each air screen. (See Fig. 11.) See Fig. 12 for
completed hood assembly.
