OZONE REDUCTION FEATURE
All electronic air cleaners produce a small quantity of ozone that
is within established limits. Some customers may notice an odor
especially at high altitudes, low air flow rates or temporarily after
the installation of new cells (new cell ozone production will
decrease after a few hours of operation).
The power pack has a three position jumper (located internally
on the corner of the high voltage circuit panel) See Figure 9. The
jumper will be in the "NORM" position from the factory. Moving
the jumper to position "A" will somewhat limit the production of
ozone by limiting maximum output power. Moving the jumper to
position "B" will limit ozone & power even more. Please note that
operating efficiency will also be reduced as ozone reduction is
increased.

OPERATION
1.
When the power switch is turned on, the green Operating
light will be ON for about ten seconds whether the blower
is on or not. This is the normal "warm-up" period for the air
flow monitor.
2.
With the blower running, the green light will be ON to indicate
that the air cleaner is operating. An arcing or "snapping"
sound may be heard. This will occur occasionally, however
the unit is operating properly. Voltage on power pack
contact and air cleaner cells (either ionizer or plates)
should be 6100 to 6800 VDC (with ozone reduction jumper
in NORMAL position).
NOTE: An occasional flicker of the green light accompanied
by harmless sparking or snapping noise may occur. It is
caused by trapping large dirt particles. If arcing is continu-
ous, the cell should be washed or check for service prob-
lems.

When the blower stops, the green light will turn OFF. Voltage
at power pack cell contact and air cleaner cells is removed.
MAINTENANCE
For maximum efficiency the air cleaner cells and pre-filter should
be inspected and cleaned on a regular basis.

The maintenance Schedule is dependent on the amount of air
passing through the filter as well as the amount of dust (pollen,
smoke, etc.) in the air. The above schedule shows estimated time
periods and may be increased or decreased based on actual
conditions. If the filter appears dirty, it is in the best interest of the
heating and air conditioning equipment to change the filter.
CLEANING
1.Turn the air moving system "OFF"
2.Push the On-Off switch on the power door to the "OFF"
position. Disconnect the power cord from the receptacle.
Wait 15 seconds for the power pack and the collecting
cells to discharge.
!
High voltage is present within the Air Cleaner for operation.
Before removing the power door, wait at least 15 seconds to
allow this voltage to be discharged.
3.Remove the power door from cabinet and set aside.
4.Remove the cells and pre-filter from cabinet. Using a
solution of warm water and low sudsing detergent, soak
cell(s) for 20 to 30 minutes.
NOTE:
Ionizing wires may become coated causing loss of
cleaning ability by the collecting cell. Using a pencil eraser,
wipe each ionizing wire, exercising care to avoid damage to
them. See Figure 11.
6.Remove the cell(s) and pre-filter from solution and rinse
thoroughly with clean water.
7.Allow cell(s) and pre-filter to drip dry for 15 to 20 minutes.
The cell(s) may be tipped at a slight angle to expedite the
drip-dry process.
8.Reinstall the cell(s) and pre-filter in the cabinet.
9.Replace the power door. Turn the blower on. After 30
minutes push On-Off switch on the power pack to the
"ON' position.
A moderate amount of arcing or "snapping" may occur at this
time, which will indicate that the cell(s) are still damp. If the noise
is objectionable, push the On-Off switch to the "OFF" position and
allow additional time for cell(s) to dry.
