The Charleswater Europe Critical
Environment overhead ionisers are
available in two models:
61 cm C/E Ioniser, 220VAC
122 cm C/E Ioniser, 220VAC
Replacement Emitter
The 92260 is a 61 cm long unit with 2
fans, and the 92261 is a 122 cm long
unit with 4 fans. Both models have the
same features permitting the user to
select the best size for the application.
The C/E series offers many design
improvements over previous overhead
models, most notably, our patented
(U.S. Patent No. 6,137,670) "Emitter
Cassette" ( see figure 1). While other
manufacturers attempt to simplify or
automate the cleaning of the emitter
pins, what remains is one major flaw in
the process - unless the ioniser is
removed to another area, the
contamination ends up on the
workstation and on any product that
happens to be nearby. The C/E series
solves this problem. When the emitters
need to be cleaned, the cassettes are
easily removed from the unit and taken
to another area to be cleaned. This
takes the dirt away from the workstation
and minimizes interruption of the work
process. To eliminate downtime, a
spare set of clean emitter cassettes can
be dropped in. The others can be
cleaned when convenient. This concept
is so unique, that we have a patent on it.

The Charleswater Europe C/E ioniser is
designed to mount above the work
area, providing even coverage without
using valuable work surface area.
Mounting is a matter of personal
preference, and may be accomplished
with brackets attached to a shelf, or the
unit may be suspended by chain.
Whatever method is used, care should
be taken to insure that the mounting is
secure and capable of supporting the
weight of the unit. The power cord
should be supported as well to provide
protection against any hazard to the
"S" hooks are provided with each unit to
facilitate mounting using the chain
suspension method. The ideal
mounting height is 122cm above the
work surface, although the ioniser may
be located slightly higher or lower if
required. Care should be taken to
insure that the intake grills for the fans
are not obstructed for maximum
Turn the power key switch to the "OFF"
position. Plug the IEC end of the cord
into the ioniser and the other end into a
properly wired outlet. We recommend
that the outlet used by the ioniser be
tested before use and periodically
checked for correct wiring and a good
solid ground. The C/E ioniser depends
on a good ground for proper balancing.
Safety interlock switches are
provided internally on each emitter
cassette. This insures that power is
cut off in the event that any cassette
is removed or not fully installed.

will decrease fan speed. Relative fan
speed is displayed on the front panel
C. BAL controls are used to adjust the
balance of the ioniser and are used in
conjunction with a charged plate
monitor. With a charged plate located
directly under the ioniser, pressing the
“+” symbol will shift the balance offset
positive, while pressing the “-” symbol
will shift it negative. The BAL controls,
like the FAN speed, are only adjustable
when the key switch is in the SET
G. LOCK - when the key switch on the
end of the ioniser is set to lock, this
indicator will display a distinctive blue
light. This makes it readily apparent
that the ioniser has its settings locked,
preventing unauthorized adjustment.
H. AIRFLOW - this display indicates
relative airflow output from the fans. If
the key switch is in the "SET" position
and the "+" or "-" button are pressed
and held, the fan speed will increase or
decrease with a corresponding change
in the AIRFLOW display. As fan speed
is increased, the display will move to the
Figure 2. Control Panel
• The CONTROL PANEL is located on
the right hand end of the ioniser. It
provides controls for fan speed,
balance, and a key switch to prevent
unauthorised adjustment of the controls.
Also located on the control panel is an
I/O port that may be used for auto
calibration (with optional accessory
cable). It also is used to provide output
signals to allow remote monitoring of
ioniser status.
A. OFF/SET/LOCK key switch - this
switch controls the power to the ioniser.
When the SET position is selected, it
allows the balance and fan speed to be
adjusted. When the LOCK position is
selected, a LOCK indicator is
illuminated on the front panel of the
ioniser. In this position, the balance and
fan speed controls are disabled and the
key is removable. In the OFF position,
power is shut off to the ioniser and the
key is removable.
B. FAN speed adjustment switches are
used to set the fan speed to the desired
level that provides the best performance
while minimizing operator discomfort.
With the key switch in the SET position,
pressing and holding the “+” symbol will
increase fan speed, and the “-” symbol
D. I/O PORT serves a dual purpose. It
accepts signals from a charged plate
monitor and automatically calibrates the
ioniser when the key switch is in the
SET position. It also outputs ioniser
status signals that can be useful for
remote monitoring.
Minor Adjustments (see figure 4) are
provided for balancing each fan zone.
These adjustments are designed for
minor adjustments to balance one fan to
another. Overall balance adjustments
should be done with the "BAL" switches
on the end panel.

The performance of the ioniser is
directly related to the airflow on the area
to be protected. Generally, try to use
the highest setting possible without
disturbing the operator or the work in
After allowing the unit to run for several
minutes, a charged plate monitor can be
used to check the balance and
performance. We recommend doing
this at the time of the initial installation,
so that data can be collected and saved
for future reference. Place the charged
plate directly under each fan and record
the float (balance) voltage. If all fans
are offset slightly in the same direction,
the “+” or “-” BAL buttons can be used
to correct the offset. If the balance
varies from a positive offset to a
negative offset between fans, the
individual fan zone controls can be
manipulated as required.
It is not uncommon to find differences
between ionisers from bench to bench
or even between fans on ionisers during
initial setup. This is often caused by the
presence of objects on or around the
bench. Large metal objects nearby or
machines or equipment on the bench
will often cause a shift in the offset
voltage at that area. The individual
zone controls of the C/E ionisers allow
this to be compensated for during initial
After balance offsets have been
checked, the decay performance of
each fan should be measured and
recorded. This information will be
useful to establish a maintenance
schedule. When decay times begin to
increase significantly, or if the red PWR
light begins to flash, emitter cleaning is
usually indicated. By recording the time
intervals between the first few
cleanings, a maintenance schedule can
be developed.
After initial setup and testing has been
done, the key switch can be set to the
LOCK position and normal workstation
use resumed.
If the ioniser is used in a manner not
specified by the manufacturer, the
protection provided by the ioniser
may be impaired.
By nature, all electric ionisers attract
contaminants to the high voltage emitter
pins. For best performance, this
contamination must be kept to a
minimum. This was a major factor in
the design process of the C/E ioniser.
Although we could not eliminate the
maintenance, we have made it far
easier and much cleaner than ever
• Turn the key switch to the OFF
• Grasp the cassette ejector levers at
the center and pivot outward about
90 degrees.
• Cleaning of the cassette can be
accomplished with a stiff brush or
lint-free swab and isopropyl alcohol
or other residue-free cleaning
• The emitter cassettes or the
individual removable tungsten
emitters can also be cleaned in an
ultrasonic cleaning tank.
See figure 4.
We recommend re-calibration every 12
months maximum, however, most users
will often choose a much shorter
interval, especially if the product being
worked on is very sensitive. On very
sensitive product, we recommend
checking the calibration any time an
emitter cassette is removed and
Warning! Do not attempt to calibrate
this unit without proper equipment
such as a charged plate monitor.
Adjustments to the calibration
controls should be performed by
authorized trained personnel only.
Balance adjustment
Using a charge plate monitor, check
each fan's balance. Use the "BAL"
switches to zero the unit. If the fans are
a little out of balance with each other
use the fan adjustment pots to equalize
them. VR5,6 and VR1,2 on 122cm

NOTE: Each fan has its own balance
circuit, however the alarm circuits tie
them together. If one or more of the
individual fan balance circuits are offset
too much from the rest it could cause
the alarm not to function correctly. If
more than a slight amount of adjustment
is required at any individual fan zone,
we recommend that the unit be reset
using the "Major Reset Adjustment"
instructions below.
2. The potentiometers in this unit have a
24-turn range. Reset all of them by
turning them at least 24 revolutions
3. Set the fan adjustment pots (VR1,
VR2, VR5 and VR6) to center by turning
them 12 revolutions clockwise.
6. Turn alarm sensitivity (VR4) 3
revolutions clockwise. Alarm center
(VR3) should be turned clockwise until
"PWR" light turns green. VR3 should
have two full revolutions in which the
"PWR" light remains green. If VR3
doesn't have two full revolutions of
green turn VR4 clockwise one turn and
check again. If VR3 has a lot more than
two full revolutions of green turn VR4
counter clockwise and check again.
Finish by setting VR3 to the midpoint of
green range.
4. Center the "BAL" control found on the
control panel on the right end of the
ioniser using the following process.
Place a charge plate under any of the
fans, push and hold the + BAL switch to
find its most positive point, use the BAL switch to find its most negative
point, calculate the midpoint and set the
balance using the "BAL" buttons to that
point. Example: if the most positive
point is +40V and its most negative
point is -10V, you would set the balance
to ±15V.
5. Fine-tune each fan by placing the
charge plate underneath it and using it's
corresponding potentiometer to zero its
balance. Turn clockwise for more
