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.
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 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 (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.
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
98132
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.
