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: 
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 6. 

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  

7KV 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. 

5.5  CHECKING AIR MOVEMENT  

(BLOWER AND DRIVE) 

1.  If the unit has deficient airflow: 

a.  Check for any type of restriction in the pick-up 

hood, flex hose or main unit. 

b.  Remove the pre-filter, cell and ionizer components 

and check for an obstruction at the diffuser plate 

directly above them. If none is present, check the 

components for excessive dirt build up. 

c.  If components are clean, remove the side access 

panel and check for: 

i.  Loose or broken belt 
ii. Defective drive motor 
iii.  Loose pulley 

 

The belt should have approximately 1⁄2” of play when 

depressed with one finger. Having the belt set too 

loose causes slippage and reduces airflow. Having 

the belt set too tight causes an over current condition 

in the motor. The resulting higher temperature 

shortens motor winding and bearing life.
