The AC input voltage can be verified or changed by removing the top cover of the unit.  

The figures below show the jumper (JH2) configuration for 120 and 220 VAC settings.  (

Note:

  

the AC power cord 

MUST

 always be disconnected before the unit is disassembled.)    

 

 

   

 

 

 

 

 

 
 

To clean the ionizer first turn off and unplug the unit.  Remove the top lid by removing 

the six screws along the top of the unit with a Phillips screwdriver.  Once the lid is removed the 
three fan modules are easily accessible.  To remove a fan module disconnect the ribbon cable 
connector from the socket and lift the fan module out.  The eight emitter points can be easily 
cleaned using Semtronics part number S204-200 emitter point cleaner, or 99% rubbing alcohol 
and a clean brush.  To clean any excess dirt off of the fan and or fan guard it is recommended 
to use compressed air.  Once the fan modules are clean slide them back onto the alignment 
posts, connect the ribbon cable, and replace the lid.
