Locate the cabinet in the cold air return duct so that all of the return air
flows through the unit (Figure 6). If the furnace and air cleaner openings
are different, use a transition (Figure 4).
Mounting holes are provided for
ductwork attachment (Figure 7). The
.140" holes are sized for #8 sheet
metal screws, or 1/8" rivets. If the
adjoining ductwork is flanged, install
the screws so that the screw heads
are inside the cabinet. This will prevent
damage to the prefilters and
optional charcoal after-filter during
removal and installation after
cleaning.
9. After the unit has been secured, seal
seams air tight with duct tape or
caulking.

ATTENTION: On Electronic Air Cleaners that have the air flow sensor
installed at the factory, be especially careful not to cover the air flow
sensor orifice when sealing the air cleaner and ductwork. This hole is
located on the right hand side of the enclosure that holds the power
pack assembly (when facing the unit). The hole is 3/16" in diameter and
is located on the front of the power tray assembly. In applications with
minimum air flow, it is helpful to seal any openings on the power tray
assembly or cabinet. This will increase the velocity of air flowing over the
air flow sensor, enabling the air flow sensor to turn the Electronic Air
Cleaner on and off. The only opening required for actuation of the
air flow sensor is the 3/16" diameter hole previously described.
10. Refer to the section entitled DIRECTION OF AIR FLOW.
11. Install prefilters and ionizer-collector cells.
12. Reinstall power trayassemblyintothe cabinet.
13. Reinstall unit access panel.
