THE SOLID STATE PERFORMANCE INDICATOR
This air cleaner is equipped with a
special solid state circuit that operates
the optional W8600E Solid State
Performance Indicator (see photo).
The W8600E Indicator is designed to be
mounted next to your thermostat, and to
monitor the air cleaner performance.
If you have ordered the W8600E
Indicator, you will notice three light-
emitting diodes (LEDs) on the W8600E
labeled ON, WASH and CHECK.
• During normal air cleaner opera-
tion, the ON LED is lit (whenever
the system fan is on).
• If excessive dirt has accumulated on the air cleaner’s 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.

OPERATINGYOUR ELECTRONIC AIR CLEANER
Set the ON-OFF switch 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 a small amount to your electric bill
each month.
When the fan comes on, the neon light
located near the ON-OFF switch will
light, indicating that the air cleaner is
functioning.
ONE-CELL MODEL SHOWN.
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.
You may hear a snapping electrical
arcing sound occasionally as the air
cleaner operates.This is usually
caused by a larger dust particle
causing a high voltage discharge.The
snapping sound means that your air
cleaner is working as it should.

If you do not 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.
When the fan stops, the neon light
goes out, as does the ON LED on the
Solid State Performance Indicator.The
air cleaner is off until the heating or air
conditioning and fan start again.

GETTINGTHE MOST FROMYOUR AIR CLEANER
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 fan controller.
The air cleaner itself uses less power than a
40 watt light bulb (two-cell model—33 watts;
single-cell model—22 watts).You will also have
the cost of running the system fan to consider.
Generally the added cost is more than offset by
the added benefits of full time air cleaning and
improved air circulation. Some people feel that
room temperatures stay more even when the
fan is always on.
Even if your thermostat does not 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 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.

CLEANINGTHE CELL(S) AND PREFILTER
To ensure optimum performance from the air
cleaner, the cell(s) and prefilter 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,
woodworking, etc.) and smoking habits. Use the
wash reminder schedule included in the literature
package to help establish and maintain a regular
cleaning schedule.
Setting 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 as soon as possible. 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
schedule that was established 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 can 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?
NOTE: You can let the heating or air conditioning system operate
normally while the cell(s) is being washed. Simply turn off the
air cleaner switch.

STEP 3
The electronic cell(s) are held in the air cleaner
by a latch at the top, and metal hooks on the
bottom. Push the cell inward to release the latch
and rotate the latch away from the cell. See
photo.
STEP 4
Lift the cell and tip it slightly to release it from
the cell hooks.
The prefilter can be vacuumed, brushed,
sprayed with a garden hose, or washed at the
same time as the electronic cell(s).
CAUTION
Burn hazard.
Can cause personal injury.
Allow the cell(s) to cool completely in the
dishwasher at the end of the wash cycle or
wear protective gloves to avoid burns.Hot
water can accumulate in the tubes
supporting the collector plates.Tip the cell(s)
so these tubes drain.
