If your air cleaner is equipped with the optional
W8600F Air Cleaner Monitor, the SERVICE and
FAULT indicator on the W8600F will remind you
that a cell and prefilter washing is due and tell
you when the system isn’t operating properly.
Whether or not your air cleaner has an Air
Cleaner Monitor, perform these checks before
you call your heating and air conditioning dealer
for service.
IF… THEN…
1. Make sure the furnace or air conditioner
blower is running.
2. Make sure the access door is firmly closed
and latched. If door is not closed properly, an
interlock keeps the air cleaner off.
3. Press the test button. A snapping sound
indicates the air cleaner is operating properly. If
there is no snapping sound, make sure the
appropriate fuse or circuit breaker is OK.
1. If the electronic cell(s) are wet from washing,
turn the air cleaner off for 2-3 hours.
2. Check the cell(s) for broken ionizer wires or
bent plates. Repair if necessary.
3. Wash cell(s) and prefilter(s) if dirty.
1. Make sure the furnace or air conditioner fan
is running.
2. Make sure the access door is firmly closed.
3. Make sure the ON-OFF switch is in the ON
position.
4. If the electronic cell(s) are wet, check again
in 2 to 3 hours.
