Honeywell F50E - Manual (Page 5)

You may hear a snapping (electrical arcing)
sound occasionally as the air cleaner operates.
This usually is caused by a larger dust particle
causing a high voltage discharge. The snapping
sound means that your air cleaner is working as it
should. To hear the snapping sound, momentarily
press the test button near the bottom of the door.
Use the test button any time you want to prove
air cleaner operation.
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.
Set the ON-OFF switch in the power box 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
to your electric bill each month.
When the fan and air cleaner come on, the neon
light in the ON-OFF switch lights.

When the fan and air cleaner stops, the neon
light goes out, and the ON LED on the W8600E
Indicator also goes out. The air cleaner is off until
the heating or air conditioning and fan start again.
