Installation
Figure 3 shows multiple mounting positions relative to the
bench top. Mounting may be accomplished by brackets
from shelving, vertical uprights, lights, or with chains hung
from the ceiling. Ensure that air flow is not impeded by the
method used.
Operation
After the ionizer has been securely mounted, connect
the power cord to the IEC connector on the back of the
unit and then to a convenient grounded receptacle. It is
recommended that the AC outlet be checked for proper
wiring and grounding, as the ionizer depends on a good
ground for offset voltage balancing.
Set the front panel rocker fan switch to either “HIGH” or
“LOW” speed fan. Higher air flow will result in a faster
neutralization rate.
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-
2:1paragraph 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.
ANSI/ESD S20.20 specifies that the compliance
verification of ionizers be tested per ESD TR53. 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 paragraph 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 paragraph
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.”

Mounting Suggestions
Mounting the ionizer is facilitated by five 1/4"-20 threaded
holes on each end and universal brackets supplied with
the unit. To avoid a potential shock hazard, be sure that
fasteners do not extend more than 1/2" into unit.

Filter for Ionizer (Optional)
A filter is available for the High Output Overhead Ionizer.
Overhead ionizers operate more effectively when the air
is free of contaminants. The filter will allow the overhead
ionizer to operate longer between maintenance intervals.
Ensure that ionizer is turned off. Remove grills and install
filters on the ionizer using screws supplied (do not re-install
grills over filters). Replacement filters (Desco item #60455)
are available. For more information on the filter, call our
customer service department at 909-627-8178 (Chino, CA)
or 781-821-8370 (Canton, MA).
