Static Electricity Test Results (VOLTS) on the Glove Box
(Neutralization is best between +/-100V)
Set the fan speed switch on the side of the ionizer to the LOW or HIGH position. Higher airflow
will result in faster neutralization rates. Position the ionizer so that the maximum airflow is
directed at the items or area to be neutralized. The LED will turn on during power up and remain
GREEN during normal operation. The ionizer has a grounding jack and must have a good earth
ground to maintain proper balance. Always plug the AC power adaptor into the ionizer and then
into the appropriate AC power source. The ionizer has no On/Off switch so it should be running
as soon as it is plugged in. The ionizer is designed to run off of 24VDC ±10% 300mA.
The balance adjustment for the ionizer can be accomplished by inserting a small screwdriver into
the balance adjustment hole located on the side of the unit. It is recommended that you use a
surface DC voltmeter when adjusting the balance of the ionizer. To increase the output in a
positive direction, turn the potentiometer in a clockwise direction. To increase the output in a
negative direction, turn the potentiometer in a counter clockwise direction.
Under normal conditions, the ionizer will attract dirt and dust (especially on the emitter
electrodes). To maintain optimum neutralization efficiency and operation, cleaning with
isopropyl alcohol should be performed on a regular basis. If the performance of the ionizer
degrades because of dirty or corroded points, the LED on the front of the unit will turn
YELLOW; the audible alarm will sound continuously. Under this condition, the unit is not able
to maintain balanced ionization. The input power cord must be disconnected before the unit is
opened for maintenance. The emitter electrodes should be cleaned using the alcohol cleaners
included or a swab wet with isopropyl alcohol. Unscrew the 4 screws on the back of the unit and
then remove the screen. After cleaning the emitter electrodes, reinstall the screen and 4 screws.
The emitter electrodes should not require replacement during the life of the unit with normal
handling. Verify the balance of the ionizer with a surface DC voltmeter after cleaning.
