The input voltage may be verified or changed to 220V by removing
the 3 screws located on the back of the unit then removing the back
case.
Input voltage is selected with two internal jumpers on JH1. For 110
volt jumper setting, a jumper must be in place shorting pin 1 to 2
and another shorting pin 3 to 4 (see figure 2). For 220 volt jumper
setting, a single jumper must be in place shorting 2 to 3 only (see
Figure 3). Make sure settign is correct before applying power
Before installing the unit, verify that the AC outlet is properly
connected to ground. The unit must have a good ground to
maintain proper offset voltage balance. Install the unit in the
desired location, making sure that the airflow will not be restricted.
Be sure the “OFF / ON” switch located on the rear of the unit is in
the OFF position. Plug the power cord into the unit and then into
the appropriate AC power source.

Operation
Set the fan speed switch on the rear of the unit to the LOW, MED,
or HIGH position. Higher airflow will result in faster discharge times.
Position the unit so that the maximum airflow is directed at the items
or area to be neutralized. Turn the unit ON. When the unit is first
turned on, it will conduct a self-test. The audible alarm will sound
and then the LED will cycle through RED, YELLOW, and GREEN.
The LED will remain GREEN during normal operation.
Figure 4. Front and Back High Output Benchtop Ionizer
Angle Adjustment Knobs - The angle of the fan may be adjusted to
direct the airflow in the optimum coverage area.
Visual Alarm -
GREEN - Normal Operation
RED - Ionizer needs maintence. Voltage supply has
dropped below normal
Fan Guard Screws -
May be removed ONLY when unit is disconnected from
power for cleaning
Front Fan Guard -
May be removed ONLY when unit disconnected from
power for cleaning
Back Fan Guard -
May be removed ONLY when unit disconnected from
power for cleaning
IEC Cord Connection -
AC line power, 120 VAC, 50/60Hz (Can be changed
internally to 220V)
On/Off Switch
Ionizer maybe turned when not in use.
Fan Speed Adjustment
3 postition fan speed: Low, Medium, High (50-100CFM)
Balance Adjustment
See Calibration/Maintenence section
If the supply voltage drops from 120 Volts to below 85 Volts, the
unit will shut down, the audible alarm will beep, and the LED will
blink RED. The unit will automatically reset when the minimum
voltage is restored. Under normal conditions the ionizer will attract
dirt and dust (especially on the emitter electrodes). To maintain
optimum neutralization efficiency and operation, cleaning should
be performed on a regular basis. When the unit enters shutdown
mode, ionization will be stopped, the LED on the front of the unit
