Mount the unit in the desired position. You can bolt the
stand to a wall or under a shelf as desired. For best results,
the unit should be mounted so that no obstructions exist
between the output area and the area to be neutralized.
of the technical requirements that are incorporated into
the ESD program plan.” And section 6.1.3.2. Compliance
Verification Plan Guidance states: “In addition to internal
audits, external audits (Organization and supplier of ESDS
items) should be performed to ensure compliance with
planned requirements. Verifications should include routine
checks of the Technical Requirements in the Plan. The
frequency of verification checks should be based on the
control item usage, its durability and associated risk of
failure.”
Under normal conditions, the ionizer will attract and
accumulate dirt and dust (especially on the emitter
electrodes). To maintain optimum performance, cleaning
must be performed on a regular basis. The electrodes
should be cleaned at least as often as indicated in the next
section. However, more frequent cleaning may be required if
used in environments with more contaminants.
METHOD 1 (Every 6 months)
The Bench Top Blower Ionizer comes with an easy-cleaning
brush which should be stored in a convenient location.
Disconnect power to the ionizer.
Then slide the brush
through the grill and across the electrodes several times to
remove the dirt and dust.
Figure 3. Wall or shelf mounting of the ionizer
Set both front panel rocker switches in the “off” position.
Connect the IEC plug into the connector on the back panel
of the ionizer, press firmly to ensure that the cord is properly
attached. Install the power cord into a properly grounded
outlet. The ionizer must be grounded for proper operation.
Desco recommends the
19219
Ground Hub Continuous
Monitor or
98130
AC Outlet Analyzer to check the ground.
Operation
Turn on the power switch and adjust fan speed for the
desired air flow. Higher air flow will result in a faster
neutralization rate.
Aim the unit so that the maximum airflow is directed at the
items or area to be neutralized.
The left rocker switch turns on a heater which will raise the
temperature of the output air to about 10°F above ambient.
The heater is only to offset the chill factor of the moving air.
It is not intended to warm the workstation.
If the ionizer is used in a manner not specified by the
manufacturer, the protection provided by the ionizer may be
impaired.
Maintenance
“As with all ionizers, periodic maintenance will be needed
to provide optimum performance.” (Reference: IEC
61340-5-2:1 paragraph 5.2.9).
The frequency of monitoring ionizers really depends on how
and where they are used. Since the majority of them use a
fan to transport the ions to the working area, the cleanliness
of the air directly affects their performance over time and how
often the emitters should be cleaned.
EIA-625 recommends checking ionizers every 6 months, but
this may not be suitable for many programs particularly since
an out-of-balance may exist for months before it is checked
again. ANSI/ESD S20.20 section 6.1.3.1 Compliance
Verification Plan Requirement states: “Test equipment shall
be selected to make measurements of appropriate properties

METHOD 2 (Annually)
To remove heavier accumulations of dirt and dust, use clean,
compressed air.
Disconnect power to the ionizer.
With
one hand firmly on top of the ionizer, aim com pressed air
through the front grill, directly at the pins. A few passes back
and forth with the nozzle is sufficient.
