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 dirt and dust (especially
on the emitter and fan guards). To
maintain optimum performance,
cleaning must be done on a regular
basis. The electrodes should be
cleaned at least every 6 months.
However, more frequent cleaning
may be required if used in
environments with more
contaminants.
This was a major factor in the design
process of the C/E ionizer. The
Replacement Emitter Cassette can be
removed to another area, and the
emitters are then very accessible.
Although we could not eliminate the
maintenance, we have made it far
easier and much cleaner than ever
before.
• Turn the key switch to the OFF
position.
• Grasp the Replaceable Emitter
Cassette ejector levers at the center
and pivot outward about 90
degrees.
• Grasping the right and left
corners, pull the Replaceable
Emitter Cassette straight out of the
ionizer.
• The Replaceable Emitter Cassettes
can then be replaced with a spare
cassette or removed to another
area for cleaning.
• Cleaning of the Replaceable
Emitter Cassette can be
accomplished with a stiff
brush or lint-free swab and
isopropyl alcohol or other
residue-free cleaning solvent.
• The Replaceable Emitter Cassettes
or the individual removable
tungsten emitters can also be
cleaned in an ultrasonic
cleaning tank.
Calibration
See figure 6.
Equipment and tools used:
- CE Ionizer
- CPA (Charged Plate Analyzer)
- Adjustment Tool for
Potentiometers
- Auto-Cal (if Auto-cal is used)
Set-up:
1. Make sure worksurface and
technician is properly grounded
2. Ionizer needs to be at least 18"
and no more than 24" from
worksurface.
3. Make sure power outlet is
properly wired and there is no
voltage in the neutral line.
4. CPA needs to sit directly under
one fan on the ionizer, any fan
will do.
BE SURE CPA HAS
BEEN RESET TO ZERO
(REFER TO CPA MANUAL
ON HOW TO ZERO CPA
PLATE)
Calibrating Ionizer:
1. Power up CE ionizer and set key
to "SET" position.
2. Hold down "+" on the fan speed
button on the side of CE ionizer
to bring fan speed to the
maximum speed setting, airflow
LED in front of unit should be
fully lit (lighting up from left to
right LED)
