NOTE: The following is a typical installation of the
air cleaner on a highboy furnace. You may have to
alter the installation to fit your particular
application.
1. Locate the cabinet in the cold air return duct such
that all of the return air flows through the unit. If
the furnace and air cleaner openings are
different, use a transition.
2. Mounting holes are provided in the Air Cleaner
cabinet for ductwork attachment. The .140”
diameter holes are sized for #8 sheet metal
screws, or 1/8” rivets. If the adjoining ductwork is
flanged, install the screws with the screw heads
inside the cabinet to prevent damage to the Air
Cleaner Pre-filters and optional Charcoal After-
Filters during removal and installation during
scheduled maintenance.
3. After the cabinet has been mounted, seal seams
air tight with duct tape or caulking.
ATTENTION: Be especially careful not to cover the
Air Flow Sensor orifice when sealing the air
cleaner and ductwork. This 3/16” diameter hole is
located in the front of the Power Tray Assembly.
4. Refer to the section entitled DIRECTION OF AIR
FLOW - Confirm correct airflow direction.
5. Install Power Tray Assembly onto the cabinet.
6. Install Pre-filters and Ionizing-Collecting Cells into
cabinet.
7. Install unit’s Front Panel Assembly onto cabinet.
