AIR CLEANER MONITOR
The optional W8600F Air Cleaner
Monitor may be added to your air
cleaner system to provide convenient
indication of system performance. The
W8600F must be ordered seperately.
The W8600F is designed to mount next
to your thermostat, or in any convenient
location (such as a utility room) where it
can be seen as it monitors the air
cleaner's performance.
The four Liquid Crystal Display (LCD)
indicators are labeled ON, BATTERY,
SERVICE and FAULT.
• The ON indicator is active during
normal air cleaning operation. The system fan is also on when the air
cleaner is running.
• The BATTERY indicator is active when the W8600F battery is low.
• The SERVICE indicator is active when it is time to wash the air
cleaner prefilter(s) and cell(s). The time between cleanings is entered
into the W8600F at installation. To turn the SERVICE indicator off,
press the Reset button located at the bottom right of the W8600F.
• The FAULT indicator is active when there is extreme dirt loading,
electronic malfunction, constant arcing or other problems with the
high voltage output of the air cleaner power supply.

When the fan and air cleaner come on, the neon
indicator lights.
If your air cleaner is equipped with a wall-
mounted W8600F Air Cleaner Monitor (see page
2), the ON indicator will be active
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.
NOTE: Depress 1 for ON, 0 for OFF.
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.
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.
When the fan and air cleaner stops, the neon
light goes out, as does the ON indicator on the
W8600F. The air cleaner is off until the heating or
air conditioning and fan start again.

If you don’t want the air cleaner to run, set the
ON-OFF switch to OFF to turn off the air cleaner.
Your furnace and air conditioner will still operate
normally, but without the added benefit of air
cleaning. Normally, this switch should be ON at
all times.

For greatest benefit, the air cleaner should run
all the time. To do this, set the fan switch on
your thermostat to ON, and make sure the air
cleaner is switched ON. The fan and air cleaner
will run even when the furnace or air conditioner
is off.
NOTE: A manual fan switch may be built into
the furnace or furnace fan controller.
The air cleaner uses less power than a 40 watt
light bulb (two-cell model—33 watts; single cell
model—22 watts). The cost of running the
system fan will vary with the size of your fan
motor and the cost of electricity where you live.
Most air cleaner owners feel that the added cost
is more than offset by the added benefits of full
time air cleaning and full time air circulation.
You may feel that the room temperature stays
more even when the fan is always on.
Although the air cleaner is designed to be
efficient over a wide range of cell dirt loading
conditions, regular cleaning is your best
assurance of consistent performance. Also, a
very dirty cell and prefilter reduces air flow and,
in turn, reduces the efficiency of the furnace or
air conditioner. The cell wash reminder sched-
ule or the optional W8600F Air Cleaner Monitor
should be used to maintain a regular wash
schedule.
An activated carbon (charcoal) filter is some-
times installed downstream of the air cleaner to
help control odors. This filter should be changed
at least annually, or as recommended by the
filter manufacturer. Honeywell does not offer
carbon filters for this application.
Replace any
activated carbon
filters in the
ductwork
regularly

If your system includes an atomizing humidifier,
you may want to install a standard furnace filter
between the humidifier and the air cleaner. This
filter would keep the humidifier spray’s mineral
deposits from collecting on the air cleaner. This
filter should be checked regularly and changed
when it shows signs of mineral or dirt buildup. If
you do not install a filter, you will probably need
to wash the cell(s) and prefilter(s) more often to
remove the mineral buildup.
If an ultrasonic room humidifier is used often,
especially if filled with tap (undistilled) water, the
cell(s) and prefilter(s) will require more frequent
washing. A white residue will accumulate on the
cell(s) from the minerals in the water. This
residue may also contribute to "white dust"
(see p. 17).
All Honeywell whole house humidifiers may be
used in a system with the Honeywell Electronic
Air Cleaner without any additional filters or
system modification.

CAUTION
Sharp edges.
Can cause personal injury.
Carefully handle the cell(s) or wear protective
gloves to avoid cuts from the sharp metal
edges.
To ensure optimum performance from the air
cleaner, the cell(s) and prefilter(s) must be
cleaned regularly—every one to six months.
Washing frequency will vary depending on the
number of family members, pets, activities
(such as cooking or woodshop) and smoking
habits. Use the wash reminder schedule that
came with the air cleaner or the optional
W8600F Air Cleaner Monitor to help establish
and maintain a regular cleaning schedule.
Mount the wash reminder schedule in a
convenient location.

If your air cleaner has a W8600F Air Cleaner
Monitor, the SERVICE indicator will activate
when it is time to wash the cell(s) and
prefilter(s). Wash them following the instructions
starting on page 9. To turn the SERVICE
indicator off, press the reset button on the lower
right of the W8600F (see picture below).
You may consider washing your cell(s) and
prefilter(s) before the SERVICE indicator
activates if some activity in your home has
changed. This can include, but is not limited to
the following:
• Have the windows been open more often?
• Has someone been smoking more often?
• Has someone taken up a dust producing
hobby?
If this activity change is permanent, you may
want your installer to change the WASH
schedule that was entered into the W8600F
when it was installed.
