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

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).
