Figure 1. Electronic Air Cleaner Cabinet with 1" Pre-Filter
Cabinet - mounts between the furnace/air handler and return air
duct work and houses the collecting cells and pre-filter.
Pre-filter - traps large particles such as hair and lint before they
can enter the cell section.
Electronic Collecting Cell - performs the actual collecting of
dust, dirt, and other impurities from the air. It contains the
ionizing and collection sections.
Each cell must be installed with the ionizing wires on the
entering air side. Each cell must be oriented with the handles
and contact button toward the front.
Power Door -
contains operating light, as well as the solid state
power supply components that convert the supplied line
voltage to the high-voltage, direct current required for the
collecting cell. Also allows access to the electronic cells and
pre-filter.
COMPONENTS OF THE AIR CLEANER
INSTALLATION
LOCATION
This air cleaner cabinet must be mounted in the return air duct
on the entering air side of a central forced-air furnace/air handler.
(See Figure 2 for example.)
Select a location that meets the following:
1. The face of the cell must be at a right angle to the air
stream.
2. Allow a minimum of 28 inches clearance in front of the air
cleaner to permit removal of cells and pre-filter.
3. Atomizing spray type humidifiers, when used, must be
installed totally downstream away from the filter.
NOTE: Do not install the air filter in the discharge air stream
of either the heating or cooling unit.

4. The air cleaner is designed for single-direction air flow.
Install the air cleaner such that the arrow always points
towards the furnace/air handler. (See Fig. 3.)
5. The pre-filter must be on the entering airstream side of the
air cleaner cabinet (the same side as ionizing wires). The
mounting flange on this side of the cabinet has the single
row of holes for attaching ductwork.
NOTE:
On Upflow furnace only applications, the air cleaner may be
installed on either side of the cabinet. See Figure 2. If
necessary, turn the air cleaner cabinet upside down for
proper air flow direction . This will reposition the pre-filter on
the side away from the furnace. The cell guide key (see
Figure 3) installed in the cabinet will allow the cells to be
installed in only the proper direction. Air flow direction must
agree with arrows embossed on the end of collecting cells
and cabinet.
