Step 1:
Check for correct number of parts. See list below:

slide dampers.
Step 2:
Remove the return air duct cover from unit and retain the
screws for later use.
Step 3:
Using a pair of 3”-4” flat sheet metal crimping pliers carefully
form the 90 Deg. mounting flanges outward along the
perforated lines around the full perimeter of the horizontal
return air opening.
Step 4:
Install outside air intake hood assembly as shown in Figure 1
over duct opening and attach with screws removed in Step 2.
Screws should attach to formed flanges to avoid possible
damage to internal components of the unit.
Step 5:
Adjust slide dampers to the desired position allowing the
correct amount of fresh air into the return airstream to meet
requirements of the building. CFM and percentage of fresh air
can be determined through the following guidelines with the
use of basic equipment. Temperature measurements for the
outdoor fresh air and indoor return air are required to calculate
the resultant supply air temperature while only the indoor
blower is operating. No mechanical cooling should be
operating while adjusting the damper blades position.
