4.4 OTHER MAINTENANCE
Instructions for replacing an ionizer wire:
1. Remove the damaged wire from each spring.
2. Replace spring if damaged.
3. Loop one end of the new wire over the bottom spring,
pull down top spring with pliers and loop the top end
of the wire over the spring hook. Refer to Figure 2.
4. Release the spring gently. The wire is now taut and
automatically centered.
Note:
In the event replacement wire is not immediately
available, remove broken wire and springs from
the assembly to allow operation until new parts
can be installed.
The following section is for the use of trained service
personnel only. The following procedures will expose
hazardous live and moving parts. Disconnect the air
cleaner before proceeding.
5. TROUBLESHOOTING GUIDE
Tools Required
1. Screwdriver: 8˝ or longer with insulated handle.
2. Volt-Ohmmeter: used to check low voltage input (120
VAC) and continuity (OHMS).
3. High Voltage Probe: used to check high voltage
power supply, minimum range from 0-15 KVDC.
* Refer also to the Troubleshooting Flow Chart
on page 6.
Normal Operation
1. Turning the toggle switch on allows 115V/1/60Hz
supply to the blower and high voltage power pack
(see Wiring Diagram, page 8).
2. The indicator light is on, and its glow is bright and
steady, indicating high voltage is present at the
power pack.
3. Air draw through the welding hood to the PCN unit is
adequate.
4. Unit is clean.
Abnormal Operation
1. The indicator light is off even though the unit blower
is running.
Possible Cause:
a. The light bulb is burnt out.
b. The high voltage power pack is defective.
c. A dead short exists in the ionizer and/or collection
cell circuit.
d. Components need cleaning.
Corrective Action:
a. Replace the bulb.
b. Replace the high voltage power pack.
c. Troubleshoot and remove the short (see how to
troubleshoot ionizer and cell circuit, page 4).
d. Remove components and clean.
2. Indicator light is flickering on/off with audible arcing
inside the cabinet.
Possible Cause:
a. An intermittent short exists in the ionizer and/or cell
circuit.
b. Components need cleaning.
Corrective Action:
a. Remove the ionizer and cell, inspect for the cause.
b. Remove components and clean.
3. The indicator light is on but the unit does not have
adequate air movement.
