(a) Place the MSH "off", and open power pack lid door.
Disconnect high voltage wire #8 to the ionizer connector
with high voltage wire #7 (Collector) connected on the
power pack and place MSH "on". the indicator light
should be illuminated. If so, the cell circuit is operational
proceed to (b). If indicator light is flashing perform the
following:
• Place MSH "off", open component door, and remove
the unicell(s).
• Place MSH "on". The indicator light should be
illuminated. if the indicator light is illuminated the
problem is within the collector cell section. if the
indicator light is flashing the problem is the high
voltage door feed through insulator (dirty, cracked,
carbon tracking) and or the high voltage wire (broken
wire or wire insulation has deteriorated causing a
dead short condition).
Parts should be replaced as required.
Inspect the unicell(s) for the following:
COLLECTOR CELL CONDITIONS
CAUSING FAILURE
• Dirty collector cell(s) (contaminant build up bridging
the cell plates and or on cell triangular insulators)
requiring manual cleaning.
• "Wet" collector cell(s), not properly dried after manual
cleaning, use compressed air to accelerate the drying
time.
• Deformed collector cell contact springs contacting a
"grounded surface".
• Bent cell plate(s) contacting the opposing cell plate(s).
• Carbon tracking to the cell triangular insulators,
imbedded black streak which cannot be removed by
cleaning (replace insulator.)
• Surface oxidation to unicell component requiring
a replacement.
• Unicell is structurally weak, loose steel rivets,
deterioration to cell plate spacers or paper thin cell
plates due to utilizing the improper detergent.
Parts should be replaced as required, install unicell(s).
Sometimes a flashing indicator light will clear itself
by removing the unicell(s) from the module and then
installing the unicell(s) back into the module.
Place MSH "off"; connect all wires which have been
disconnected and install unicell(s).
(b) indicator light is illuminated with the high voltage
wire #7 connected to the collector cell connector on the
power pack. Place MSH "off" and connect high voltage
wire #8 to the ionizer connector on the power pack.
Place the MSH "on".

The indicator light should be illuminated? If so, the
unicell(s) are operational. If the indicator light is flashing
perform the following:
• Place MSH "off", open the component door, and
remove unicell(s).
• Place MSH "on". If the indicator light is illuminated the
problem is within the ionizer section. if the indicator
light is flashing the problem is the high voltage door
feed through insulator (dirty, cracked, carbon tracking)
and or the hv wire (broken wire or wire insulation has
deteriorated causing a dead short condition).
Parts should be replaced as required, install unicell(s).
Inspect the unicell(s) for the following:
IONIZER CONDITIONS CAUSING FAILURE
• Dirty ionizer(s) (contaminant build up) requiring
manual cleaning.
• "Wet" ionizer(s), not properly dried after a wash cycle
or manual cleaning procedure, use compressed air to
accelerate the drying time.
• Deformed ionizer contact springs contacting a
"grounded surface."
• Broken ionizer wires.
• Contaminant build up and or cracked ionizer stand off
insulators.
• Carbon tracking (black streak) to the ionizer stand off
insulators (replace insulator).
• Ionizer wires not "taut" contacting the ground plates.
• Bent ionizer wire support bar contacting a "grounded
surface."
• Bent ground plates contacting the ionizer wires.
• Surface oxidation to unicell component requiring
a replacement.
• Unicell is structurally weak or has loose rivets.
Parts should be replaced as required.
Sometimes a flashing indicator light will clear itself
by removing the unicell(s) from the module and then
installing the unicell(s) back into the unit.
