A high voltage probe is required to measure high voltages
to the ionizer and collector circuits to the unit, as well as
to perform the “Bench test Procedure” (Section 12). as an
accessory, a high voltage probe can be purchased for a
multimeter.
High Voltage Specifications:
ionizer circuit operating range: 10.0 to 11.8 KVDc
collector cell circuit operating range: 5.0 to 7.5 KVDc
there are two factors which will elevate ionizer voltages
above 12.0 KVDc:
• The ionizer wires are heavily coated with contaminant
(two to three times or greater, the diameter of the wire).
this will decrease collection efficiency.
• There are “run away” voltages to the power pack
requiring power pack replacement, above 12.0 KVDC
to the ionizer circuit, and 7.6 KVDc to the collector
cell circuit.

Checking Cell Voltage
there will be continuous cell arcing if cell voltages
exceed 7.5 KVDC. This is also caused by “run away”
voltages to the power pack requiring power pack
replacement. a high voltage measurement can be
performed by removing both the high voltage wires from
the power pack to determine high voltage output. the
high voltage measurement should not exceed “High
Voltage Specifications.”
if there is a dead short condition or arcing, the problem
is typically within the collector cell. follow Step 1 below
to ensure power pack is operational. install all ionizers
and collector cells within the unit with proper electrical
alignment before proceeding with troubleshooting
Steps below. refer to figure 14.
Step 1 and 2 do not require a high voltage probe.
STEP 1
CHECK THE POWER PACK
the power should be placed in the off position to the
power pack. carefully disconnect both high voltage
wires (ionizer #8 and collector #7) from the power
pack. the high voltage wires should carefully be placed
away from the ionizer and collector cell power pack
connectors, eliminating the high voltage wires from
contacting the power pack connectors. Place the power
to the unit in the on position; the indicator light should
be illuminated.
• If the indicator light is illuminated, the power pack is
operational. Proceed to Step 2.
• If the indicator light is flashing (high voltage wires #8
and #7 disconnected from the power pack), the power
pack should be replaced.
• If the indicator light is not illuminated, verify there is
120 Vac to the power pack. Place power in the off
position to the unit, and remove the 120 Vac wires
from the power pack. connect a meter to the two 120
Vac wires and place the power in the on position. if
120 Vac is not present, there are problems upstream
from the power pack, complete the following until the
problem is corrected:
o the electrical disconnect should be in the “on”
position.
o ensure the limit switch is mechanically engaged to
the component access door.
o check limit switch failure (120 Vac) to the power
pack circuit. (Measure Vac before the limit switch
and engage limit switch measuring voltage after
the limit switch). the mechanical engagement of
the limit switch should be checked by closing the
component access door.
o check for blown fuses to the main disconnect.
o check if fuses are failed to the primary and or
secondary side of the step down transformer (if
equipped).
o check for loose wire terminal screws or
disconnected wires at the terminal blocks.
o check for indicator light failure. check wire
connections (#9 and #2) to the power pack, and
to the indicator light. the indicator light is an LeD
