Honeywell F50E - Manual (Page 21)

If your air cleaner is equipped with the optional
W8600E Indicator, the WASH and CHECK
LEDs on the W8600E will remind you that a cell
and prefilter washing is past due and tell you
when the system isn’t operating properly.
Whether or not your air cleaner has a Solid
State Performance Indicator, 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. Make sure the air cleaner
power switch is in the on position.
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 fuse or circuit
breaker that powers the air cleaner is OK.
1. If the electronic cell(s) are wet from washing,
turn off the air cleaner off for 2 to 3 hours.
2. Check the cell(s) for broken ionizer wires or
bent plates. Repair if necessary.
3. Wash cell(s) and prefilter(s) when dirty.
1. Make sure the furnace or air conditioner fan
is running.
2. Make sure the access door is firmly closed.
3. On models without the Solid State Perform-
ance Indicator, if the electronic cell(s) are wet,
check again in 2 to 3 hours.
4. Press the test button. A snapping sound
indicates the air cleaner is operating properly,
but the neon light is not working. If there is no
snapping sound, make sure the appropriate
fuse or circuit breaker is OK.
