9100 Benchtop Air Ionizer
Installation, Operation and Maintenance
Description
The SCS 9100 Benchtop Air Ionizer is a self-contained,
ionized air blower designed to neutralize electrostatic
charges from non-conductive objects (insulators) and
isolated conductors. The SCS 9100 meets ANSI/ESD
S20.20 tested per ANSI/ESD STM3.1 and ESD TR53.
The ionizer is designed to continuously generate equal
levels of positive and negative ions regardless of high or
low fan speed.
The SCS 9100 Benchtop Air Ionizer is available in four
models:
Item Input Voltage Power Cord
9100-CP 220 VAC China
9100-JP 110 VAC Japan / U.S.A.

Installation
The Benchtop Air Ionizer mounts easily in a variety of
positions using the provided tilting bracket/stand. Mount
the bracket by following the illustration below. Secure
the mounting bracket with screws on table top. Adjust
the angle of air flow towards the target and secure it by
tightening the side knobs.
Maintenance
1. When performing emitter points maintenance,
disconnect the power cord from the electrical outlet.
Do not connect or disconnect the power plug with
wet hands as doing so puts you at risk of electrical
shock or injury.
2. Occasional cleaning of the case and emitter points
is the only routine maintenance required. Check
for any particle build-up on the emitter points.
Verification and adjustment may be required to keep
the balance within the specification range.
3. Cleaning the Case - Wipe the case with a
moistened, fully squeezed soft cloth with deionized
water. If a stronger cleaning solution is required,
use a soft cloth with a mixture of alcohol and water
(70% IPA and 30% DI water). Do not use any other
solvents that can damage the coating of the case.
Fully squeeze the cloth or sponge to remove any
excess liquid.
4. Cleaning the Emitter Points - The emitter points are
accessible through the front grill. To clean them,
turn off the unit; clean the points with a cotton swab.
Use caution when accessing the emitter points to
avoid injury. Access to the points is available by
pressing the side tabs, and pulling off the grill (see
images below). Use caution when removing the
grill to avoid breaking the cable that connects the
grill. Be careful not to bend the emitter points during
cleaning. The emitter points are fixed and therefore
not replaceable.

at a time.
2. Mount the bracket using
three screws.
3. Replace the fan body. Tighten
both knobs to a desired air flow
abgle towards the target of
ionization.

Figure 4. Installing the Benchtop Air Ionizer
The safety of any system incorporating this equipment
is the responsibility of the assembler of the system. The
ionizer’s performance is affected by its distance from
the worksurface and fan speed. As distance increases
or fan speed is reduced, the discharge time at the work
surface will increase.
WARNING: The Benchtop Air Ionizer is not designed to
be used in explosive areas or flammable atmospheres.
Sparks from the fan motor or emitter points may cause
ignition.
Electrical
Use the included power cord located at the back of
the ionizer. For proper operation, the unit must be
grounded for safe operation.
Grounding
The Benchtop Air Ionizer must be connected to ground
through the GROUND Terminal behind the unit and
the ground wire included in the package. Connect the
ground wire to a known good electrical ground. Failure
to connect the ground terminal may cause the unit to
malfunction.
Operation
1. Insert the power cord into an electrical outlet.
Make certain that power line voltage is within the
operating range of the ionizer. The use of improper
power line voltages may impair operation or damage
the unit. This will void the warranty.
2. The power switch on the front of the unit turns
the power and LED Power Indicator illuminates
when it’s on. The dial knob adjusts the fan speed.
Rotating it clockwise increases the fan speed.
Remove the front grill by
pressing and pulling the tabs
on each side of the grill.
Wipe the emitter tips and fan
blades with a cotton swab or
brush.
5. Re-attach the front grill after cleaning the emitter
points and fan blades.

6. Service - If you believe that a unit is not functioning
properly, disconnect the unit from power. If the unit
is covered by Warranty, contact your Desco Asia
sales representative or distributor.
CAUTION: There are no user replaceable parts.
Unauthorized replacement of parts will void the
warranty.
Calibration
Offset Voltage Calibration
1. The equipment needed to measure the offset
voltage is a calibrated charged plate monitor or
equivalent set to voltmeter mode. Refer to the
User’s Guide accompanying the CPM for proper
operation and setup.
2. Position the Benchtop Air Ionizer and CPM as
shown below.
Troubleshooting
Problem Action
The fan does
not turn.
Turn o󰀨 the unit. Disconnect the AC
plug from the outlet. Be sure to contact
a Desco Asia sales representative or
authorized dealer to request inspection
and repair. Repairing the product
yourself is dangerous and will void the
warranty. Do not attempt to repair the
product yourself.
Unbalanced
ion levels.
Ion balance
cannot be
adjusted to
0V.
Check that the environmental
conditions at the installation site
fall within the service environment
conditions of the unit.
Perform cleaning of the emitter points
as described in the “Maintenance”
section.
Turn o󰀨 the unit if the above step does
not improve the situation. Disconnect
the AC plug from the outlet. Be
sure to contact a Desco Asia sales
representative or authorized dealer
to request inspection and repair.
Repairing the product yourself is
dangerous and will void the warranty.
Do not attempt to repair the product
yourself.
Others
Examples:
Abnormally
slow rotation
of the fan,
the unit being
abnormally
hot, a
burning odor,
abnormal
noises, etc.
Turn o󰀨 the unit. Disconnect the AC
plug from the outlet. Be sure to contact

3. Turn on the power for the ionizer and the CPM. Let
it warm up for 5 minutes.
4. Set the ionizer fan speed to maximum.
5. Set the CPM to voltmeter mode and select a smaller
scale, example: 25 Volts.
6. Locate the Offset Voltage Adjust trimpot and slowly
turn the small screw head using a mini screwdriver.
Observe the CPM reading as you turn. Stop turning
as soon as the CPM reads as close to zero volts as
possible.
7. Proceed to do the Decay Time and Offset Voltage
verification.
Decay Time and Offset Voltage Verification
1. Set the CPM to Decay/Offset mode. Refer to the
User’s Guide accompanying the CPM for proper
operation and setup.
2. Set the CPM to decay and offset voltage mode
with a starting charge at either + or – 1 KV and a
stopping charge at either + or -100 Volts.
3. Start the decay/offset test sequence on the CPM.
This will take a few seconds.
4. Record the decay time, and offset voltage as
displayed on the CPM.
