OPERATING YOUR ELECTRONIC AIR CLEANER
Set the ON-OFF switch to ON. The air cleaner will now operate whenever your furnace/air conditioning system fan operates. For maximum air cleaning benefit and cleaner air conditioner coils, leave the air cleaner switch on at all times and the fan switch on your thermostat on. Of course, continuous fan operation will add a small amount to your electric bill each month.
When the fan comes on, the neon light located near the ON-OFF switch will light, indicating that the air cleaner is functioning.
If your air cleaner is equipped with a wall-mounted W8600E Solid State Performance Indicator (see page 2), the ON LED will be on whenever the air cleaner is in operation. Of course, the system fan will also be running.
You may hear a snapping electrical arcing sound occasionally as the air cleaner operates. This is usually caused by a larger dust particle causing a high voltage discharge. The snapping sound means that your air cleaner is working as it should.
