Adjusting High Voltage Output
In case of excessive arcing on a clean, dry Cell, there is
an adjustable resistor mounted on the Power Board.
1. Turn off the system switch before opening the unit.
2. Remove the cover by slipping the "S" hook from the
chain and letting the cover gently down.
3. Lift the cover up off the rear hinge.
4. Remove the power box cover.
5. With a small slot screwdriver, adjust "R-2" slightly
clockwise to reduce voltage to the cell. Do not reduce
the voltage too much or the efficiency of the air
cleaner will be reduced.
Removing The Power Box
1. Shut off main breaker or switch.
2. Remove the cover as described previously.
3. Open power box cover.
4. Disconnect the following wires:
Terminal Block -Red, blue or yellow, black and
white leads from motor
-Supply line leads
Power Board
-Orange or grey leads on
HV1 and HV2
5. Remove the two nuts holding the power box to the
cell section.

TROUBLESHOOTING GUIDE
PROBLEM:
CHECK:
Unit Does Not
Operate
1. Main breaker is
ON
or voltage
is supplied to unit.
2. Main supply fuse or breaker is
not tripped.
3. Unit cover is completely closed
and locked into place.
4. Power switch is
ON
.
Performance
Indicator Light Is Not
Lit
1. System switch is
ON
.
2. Remove Cells, close access
door and turn unit
ON
. If
Performance Indicator is still
off, problem is in the power
box. If light comes on with no
cells, then there is a short
circuit in the cells. Place one
cell in the unit, close access
door and turn unit
ON
. If the
light comes on, check the other
cell by the same method.
When it has been determined
which cell is the problem, look
for bent plates, broken ionizing
wires or burnt insulators or if
cell is completely dry after
washing.
Performance
Indicator Light Is Lit,
Fan Not Working
1. Fan control switch is in proper
position.
2. Motor leads are connected to
terminal block.
Cells Arcing
Excessively
1. Cells are completely dry after
washing.
2. Cell plates are not bent or
spaced too close.
3. Cell insulators are not cracked,
broken or burnt.
4. Cell is dirty and needs cleaning.
5. Broken ionizing wires.
