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 the prefilters and optional
charcoal after--filter during removal and installation after
cleaning.

3. After the unit has been secured, seal seams air tight with foil
tape or caulking.
4. Determine direction of airflow and make any changes
necessary.
5. Install prefilters and ionizer--collector cells.
6. Reinstall power tray assembly into the cabinet.
7. Reinstall unit access panel.
ELECTRICAL INSTALLATION
ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in personal injury
or death.
The following procedures could expose hazardous live
components. Only a trained, experienced service person
should install this electronic air cleaner. Before performing
installation, service or maintenance operations on unit, turn off
all power to u nit. TAG DISCONNECT SWITCH WITH
LOCKOUT TAG.
!
WARNING
The Electronic Air Cleaner is designed to take advantage of the
AFS (AirFlow Sensor) integrated into the power supply. This
airflow sensor will sense the air movement within the duct and turn
the Electronic Air Cleaner on and off accordingly.
Wiring Procedure
This air cleaner is powered by plugging the power cord into an
acceptable receptacle (see Fig. 10).
1. Safety Interlock Switch
2. ON/OFF Rocker Switch
3. 50 VA Stopdown Transformer
4. High Frequency Power Supply
5. Electronic Air Flow Sensor
6. Ionizing-Collector Cells
7. Contact Board Assembly

1. Turn air cleaner OFF using ON/OFF rocker switch located
on front panel.
2. Plug power cord into acceptable receptacle.
3. Replace the unit door to the front of the air cleaner.
4. Air cleaner will now operate when door is in place,
ON/OFF rocker switch is in the ON position and input
voltage is present to unit.
Furnace Application
AFS will turn unit on when airflow is sensed. Air cleaner should
only operate when blower motor is running. The unit will also
operate normally if the air cleaner is hard wired directly to the
furnace control board. To bypass the airflow sensor, install the
jumper on the JP9 prongs as shown in Fig. 4. Now the air cleaner
will run at all times when power is applied.
UNIT DAMAGE HAZARD
Failure to follow this caution may result in damage to this
unit.
This unit cannot be powered directly from blower motor
leads. Back EMF (electromagnetic field) voltages can exceed
190 volts for 120v motors or possibly double with 240v fan
coil motors.
CAUTION
!
Fan Coil Application of 2020 Model (240v)
One Model 2020 is a 240v power supply model designed to match
your fan coil. AFS will turn unit on when airflow is sensed. Air
cleaner should only operate when blower motor is running.
UNIT DAMAGE HAZARD
Failure to follow this caution may result in damage to this
unit.
This unit cannot be powered directly from blower motor
leads. Back EMF (electromagnetic field) voltages can exceed
190 volts for 120v motors or possibly double with 240v fan
