THE SOLID STATE PERFORMANCE INDICATOR
This electronic air cleaner is equipped
with a special solid state circuit that
operates the optional W8600E Solid
State Performance Indicator (see
photo). The W8600E Indicator must be
ordered separately.
The W8600E Indicator is designed to
mount next to your thermostat, or in any
convenient visible area (such as a utility
room) where it can be seen as it
monitors the air cleaner's performance.
The three light-emitting diodes (LEDs)
on the W8600E are labeled ON, WASH
and CHECK.
•The ON LED is lit during normal air cleaning operation. The
system fan is also on when the air cleaner is running.
•If excessive dirt has accumulated on the air cleaner cell(s),
the WASH LED will light to alert you that a cell and prefilter
wash is past due.
• Extreme dirt loading (beyond that required to activate the
WASH LED), electronic malfunction, or other equipment
problems will cause the CHECK LED to light.

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.

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 efficiency, 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), and the cost of running the
system fan is also quite low. The small added
cost is more than offset by the added benefits of
full time air cleaning and full time air circulation.
Some people feel that room temperatures stay
more even when the fan is always on.
Even if your thermostat doesn’t have a fan ON
position, you can obtain maximum available air
cleaning benefit by making sure the air cleaner
is always switched ON so it operates whenever
the furnace or air conditioner is 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, this reduces the efficiency of the furnace
or air conditioner. The cell wash reminder
schedule 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.

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 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 when 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. 18).

CAUTION
Sharp edges.
Can cause personal injury.
Handle the cell(s) carefully 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 woodworking) and smoking
habits. Use the wash reminder schedule
mounted on top of the air cleaner or furnace to
help establish and maintain a regular cleaning
schedule.

If your air cleaner has a W8600E Indicator (shown on page 2), the
WASH LED will light to remind you that a cell and prefilter washing is
past due. When the WASH LED comes on, it means that the cell(s) are
loaded with dirt to the point that air cleaning efficiency is diminished.
You should plan to wash the cell(s) and prefilter(s) as soon as possible.
But by using the wash reminder schedule, a washing schedule can be
established that keeps the cell(s) clean enough so the WASH LED does
not come on.

If you find that the WASH LED is coming on more frequently than the
established schedule on the wash reminder schedule, you may have a
buildup of residue on the ionizer wires. If the collector plates on the
cell(s) look clean, you can try wiping the ionizer wires with a clean cloth
instead of washing the entire cell.
You might also consider whether some activity in your home has
changed, causing the cell(s) to become dirty faster. Have the windows
been open more often? Has someone been smoking more often? Has
someone taken up woodworking or some other hobby that creates
dust?
NOTE: You may let the heating or air conditioning system operate
normally while the cell(s) are being washed. Simply turn off the air
cleaner switch.
The prefilter(s) should be vacuumed, brushed,
sprayed with a garden hose, or washed at the
same time as the electronic cell(s).
