Maintenance on the Optional Ionizer
Occasional cleaning of the ionizer’s emitter points is the only routine maintenance
required. Regularly scheduled cleaning extends the life of the unit and sustains the
delivery of ionized air. Clean the emitter points every 60 to 90 days (based on 8-hr
daily operation).
Emitter Point Cleaning
NOTE: Disconnect power to the XPert Nano Enclosure at least
one minute before performing cleaning or replacement of the
Ionizer Emitter Points. The ionizer has a high voltage power
supply that must discharge over that one minute time period.
Emitter points are better cleaned without removal. Use a clean room compatible
(non-shedding) swab moistened with the following solution to gently wipe the
points.
Cleaning solution of 50% IPA (laboratory or electronic grade
isopropyl alcohol and 50% de-ionized water).
Emitter Point Replacement
If the ionizer fails to neutralize charges in the airstream, the only portions of the
ionizer that can be serviced are the emitter points. Do not attempt to disassemble
the ionizer bar located under the work surface. A surface static charge meter is
required to test the ionizer’s effectiveness. Apply a static charge to a piece of
plastic with a synthetic fabric and measure the voltage at the surface before and
after placing it in the airstream with the ionizer ON.
