IMPORTANT WIRING INFORMATION

This Electronic Air Cleaner is equipped with an Air Proving Switch (APS). The

recommended source for the input voltage to the Air Cleaner is from the same

source that is supplying the heating/cooling equipment, providing it is the

same voltage as the Air Cleaner. The Air Cleaner should be wired directly to

the power source. The APS will power the Air Cleaner when there is sufficient

airflow to activate the sensor.

If you wish to wire the Air Cleaner to the EAC / Accessories Module on the

circuit board of the furnace or air handler, ensure that there is 115 Volt output

from these terminals, when the unit is run manually and is running on low

speed. Some manufacturers do not supply full output voltage to the terminals

in the low speed mode, so the Air Cleaner will not function. The green

Performance Indicator Light will not turn on.

The Air Cleaner performs best when the system fan is on “FAN ON” or

“Continuous” mode, and is run on the low speed. Check the output of the

terminals with a volt meter when running on low speed, before wiring the Air

Cleaner to the circuit board.

The Air Cleaner must be wired to operate only when the system fan is on.

See page 5 of the Owner’s Manual for more information on wiring.
