LOCATING THE AIR FILTER

Your air filter 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 the following clearances to permit removal of
cells and pre-filters: (See Figures 4 and 5)
Model SST1000 - 14 inches
Model SST1400 - 15 inches
Model SST1600 - 14 inches
Model SST2000 - 15 inches
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.

IMPORTANT: IMPORTANT:
IMPORTANT: If atomizing spray type humidifier is
used, it must be installed downstream from the air
filter.
If your furnace duct system has a pre-installed boot,
discard front cover of boot and slide the air cleaner
component inside the boot. For installation of Air Cleaner
Retrofit (ACR) kits, see page 13.
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).

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).
