WARNING
Personal Injury Hazard
To avoid the possibility of property damage, personal injury, or death, a trained, experienced servicer should install
this electronic air cleaner. Power supply must be disconnected before installation, and a thorough checkout of the
unit installation must be completed before unit operation.
THIS AIR CLEANER SHOULD NOT BE INSTALLED ON THE HOT AIR SIDE OF DUCT-TYPE SYSTEMS.
1. Remove the old furnace filter and discard.
2. Remove any existing dirt from the blower and ducts.
The air cleaner cannot remove existing dirt. The
area must be thoroughly clean before you begin.
3. Remove unit access panel, and slide the pre-filters
and ionizing-collecting cells out of the cabinet. Place
them safely aside with the warranty registration card.
4. Locate the cabinet in the cold air return duct so that
all of the return air flows through the unit (Figure 11).
If the furnace and air cleaner openings are different,
use a transition refer to page 4, Figure 2.
5. Mounting holes are provided for ductwork attach-
ment (Figure 12). The 0.140” holes are sized for #8
sheet metal screws, or 1/8” rivets. If the adjoining
ductwork is flanged, install the screws so that the
screw heads are inside the cabinet. This will prevent
damage to pre-filters and optional charcoal after-filter
during removal and installation after cleaning

6. After the unit has been secured, seal seams air tight
with duct tape or caulking.
ATTENTION:
Be especially careful not to cover the airflow
sensor orifice when sealing the air cleaner and ductwork.
This hole is located on the right hand side of the cabinet that
holds the power tray assembly (when facing the unit). The
hole is 3/16” in diameter and is located on the front of the
power tray assembly (see Figure 1). In applications with
minimum airflow, it is helpful to seal any openings on the
power tray assembly or cabinet. This will increase the
velocity of air flowing over the airflow sensor, enabling the
airflow sensor to turn the electronic air cleaner on and off.
The only opening required for actuation of the airflow
sensor is the 3/16” diameter hole previously described.
7. Set airflow direction (see
“Directing Airflow Through
the Cleaner”
section for the correct setup).
8. Install pre-filters and ionizer-collector cells.
9. Reinstall sliding power tray assembly into the cabi-
net.
10. Reinstall cabinet access panel.
CAUTION
Only a trained, experienced serviceman should
install this electronic air cleaner. The power tray
assembly should be removed before installation. To
remove the power tray assembly, remove the two (2)
screws (see Figure 12) in the top front of the
cabinet. Remember to keep this hardware for
reinstallation of the power supply when the air
cleaner installation is complete. A thorough
checkout of the unit installation should be completed
before unit operation.
Read these instructions carefully before attempting to
install or operate the air cleaner. Failure to follow could
result in improper installation and a voided warranty. This
electronic air cleaner has a BUILT-IN automatic air flow
sensor (AFS) that senses the air movement within the duct
and turns the electronic air cleaner on and off accordingly.
NOTE:
The following is a typical installation of the air cleaner on
a highboy furnace (Figure 5). You may have to alter the
installation to fit your application.
