1. Turn the system OFF at the thermostat by changing the mode selector to OFF –
this may be a switch or a pushbutton, depending on the type of thermostat.
2. Disconnect power service to the furnace or air handler.
3. Remove air cleaner power pack / door assembly and pull inner assembly out
of the outer housing.
4. Remove the media carton and the cardboard inserts and strapping, used to
hold the media, from the inner housing.
5. On retrofit applications, remove and discard the existing filter and filter
housing. Thoroughly clean the blower, blower compartment and evaporative
coil.
6. With the airflow label on the outer housing pointing toward the furnace/air
handler (see Figure 10), attach the outer housing to the furnace/air handler.
7. Provide support for the housing, as
shown in Figure 10, if the unit is to be
installed on the side of an upflow
furnace/air handler (see example of this
type of installation in Figure 6).
8. Seal the perimeter of the inlet and outlet
connections with mastic or caulk as desired.
9. Open the inner housing and install the
media. Use the instructions provided on the
carton of the media.
10. After installing the media, close the inner
housing. Check the media ground strip to
ensure it is properly contacting the pleats –
see Figure 11. If not, remove the ground
strip by removing the ground contacts, and
reposition as shown in Figure 11. Verify
that the holes in the media ground contacts
go over the ground contact retainer posts.
11. Check to make sure that the ionizer frame is fully installed onto the inner
housing and that the control electrode is inserted fully into the ionizer frame.
12. Insert the inner assembly (ionizer frame and inner housing) into the
outer housing.
