PREINSTALLATION
facing the power door. Air flow direction must agree with
arrow embossed on end of collecting cells.
After installing the cell sections, install pre-filters in cabi-
net tracks on the right. This will again place the pre-filters
on the air entering side (on the same side as ionizing
wires).
LOCATING THE AIR FILTER
Your electronic air cleaner must be mounted in the return
air duct of a central forced-air system, on the air entering
side of your furnace. (See Figure 3 for example.)
Select a location that meets the following:
1. The face of the cell will be at a right angle to the air
stream.
2. Allow a clearance of 14 inches to permit removal of
cells and pre-filters: (See Figures 4 and 5).
For complete dimension data refer to Figure 5.
3. The air filter is not to be placed in the discharge of
either the heating or cooling unit.
4. IMPORTANT: If atomizing spray type humidifier is
used, it must be installed downstream from the air
filter.
If furnace opening cannot be enlarged to required size, a
transition sheet metal section must be used. Transition
must be planned for each job. Reduction should not be
more than 4 inches per linear foot, approximately 20
angular degrees (Figure 3).
DIRECTION OF AIR FLOW THROUGH THE
AIR CLEANER
Your air cleaner is shipped from the factory with air flow
from left-to-right. If this air flow is suitable for the installa-
tion, no further changes need to be made (Figure 4). For
right-to-left air flow, remove both pre-filter and cell sec-
tions. Turn cells upside down (with the same end facing
the cabinet opening). This will locate the ionizing wires at
the right, and both contact buttons and cell handles will be
