1. Remove the cell and depress the door interlock switch.
2. If the indicator light comes on, the problem is in the cell. Check for the following:
a. Excessive build up between cell plates.
b. Something lodged between the cell plates, bowed or bent plates, etc.
c. Cracks in any of the eight cell insulators, carbon tracking or other insulator damage.
3. If the indicator light remains off with the cell out of the unit, remove the ionizer and activate the
power supply.
4. If the indicator light comes on, the problem is in the ionizer. Check for the following:
a. Broken or loose ionizer wires.
b. Excessive build up on insulator(s).
c. Cracked or broken insulator(s).
5. If the light remains out with both the ionizer and cell removed, remove the side access panel and
check out the high voltage power pack. See Figure 5.
a. Remove both high voltage leads from the end of the power pack.
b. Measure high voltage (use probe) at terminal No. 8 (output to ionizer) and terminal No. 7
(output to collector).
c. If no voltage is present or voltage is below minimum, replace the power pack.
Note: Minimum reading with high voltage wires removed: 11KV at terminal No. 8 (ionizer) and
5KV at terminal No. 7 (collector).
6. If voltage is present and within limits, check for:
a. Short in the high voltage lead wires.
b. Cracked or broken cabinet insulators.
5.4 Determining the Loss of High Voltage
As components build up dirt, the indicator light
dims then goes out at a point approximately
3.5KV cell voltage. If satisfactory operating
voltage is present at the ionizer and cell and
the light is out, the problem is either a defective
indicator light or light circuit.
If no voltage is present at the cell, and the
indicator light is out:
