will change to a steady RED, and the audible alarm will sound 

continuously. If the ionizer enters shutdown mode, it must be turned 

OFF and then back ON to reset the unit.  (See following Calibration 

section for more info.)

In the event of circuit failure, the unit will enter shutdown mode.

When the unit enters shutdown mode, ionization will be stopped, 

the LED on the front of the unit will illuminate a constant red, and 

the audible alarm will continuously sound.  The user must then 

reset the unit by turning it OFF and back ON.

Figure 5 Cleaning the Emitter Points

Cleaning the Emitter Points

Turn electrical power OFF.

 

I. Turn the unit OFF and unplug the power cord.

 

II. Remove the rear screen by removing the 4 screws.   

 

    See Figure 5

 

III. Clean the emitter points using the included 60506

 

                   Emitter Point Cleaners or a swab dampened with 

 

 

     Isopropyl alcohol

 

IV. Reattach the rear screen.

 

V. Plug in the power cord and turn the unit ON.

 

VI. Verify the offset voltage balance of the ionizer by  

 

     using a charge plate monitor or ionization test kit.

The emitter electrodes should not require replacement during the 

life of the unit with normal handling.  If necessary, item 60507 

Replacement Emitter Points are available for order.

ESD TR53 does not advise a test frequency for ionizers.  Your 

maintence schedule will depend on the requirements of your 

ESD Control Plan.  In order to manage service intervals, Desco 

recommends assigning a number or other identification method for 

each ionizer in your Maintence / Calibration schedule.  You may 

choose to use the ionizer’s serial number for identification, as it is a 

unique number for identification, as it is a unique number that can 

be traced to when the ionizer was manufactured.

Neutralization (Discharge) Times

The comparative efficiency of overhead ionizers is determined by a 

standard test published by ANSI/ESD S3.1.  Typical positive and 

negative discharge times (in seconds from 1000 volts to 100 volts 

and from -1000 volts to -100 volts) measured using this standard 

are shown below.  The performance of the ionizer was measured 

with the unit positioned as shown, with the fan speed on high, and 

without a filter.

The typical discharge times measured using this standard for 

the ionizer are shown in the following diagram. They are not 

guaranteed maximum discharge times

Note: Reference ANSI/ESD STM 3.1. At room ambient temperature 

and relative humidity.
