Attaching Power Exhaust to the Unit
1. Make sure all power exhaust harness are connected as
indicated in the previous steps. See Fig. 6 and 7.
2. Make sure all wiring is secure. Use field-supplied wire
ties if necessary. Be sure that wiring does not interfere
with operation of the HVAC unit, economizer, or power
exhaust.
3. For units with a standard filter panel (i.e., no hinged
door): Install the gasketing (provided) on the back of
power exhaust side mating flanges. (See Fig. 11.)
NOTE: This step does not apply to units with a hinged
door.

5. Locate the aluminum filter shipped with the economizer.
Open the filter clips under the top hood of the power
exhaust. Slide aluminum filter into the outside air open-
ing of the power exhaust. Filter will slide past filter clips.
Close filter clips, which will lock filter in place.
6. Reinstall the fan shield.
7. Return power to unit and remove lockout tag.
8. Test power exhaust operation by setting the power
exhaust set point on the economizer controller to 0%.
Power exhaust performance is shown in Fig. 13.
9. Adjust the power exhaust set point on the economizer
controller to the desired activation point per unit sche-
matic.
10. For units with a standard filter access panel, reinstall the
unit filter access door.
For units with a hinged access door (Small and Large
Cabinet), install the hinged door seal angle included in
the power exhaust kit using the instructions in this
instruction. Do not proceed unless the sealing angle is
installed. Units with a hinged door that do not have a
sealing angle may not have a watertight seal.
