1 General information
This ionizer is equipped with blades supplied with high
voltage, in the immediate vicinity of which positive and
negative ions are generated as a result of corona dis-
charge. They are attracted through the weighed material
with static charge, thus neutralizing the interfering static
charge. This eliminates also the forces leading to false
weighing results (e.g. false weighing result, floating weigh-
ing value).
2 Basic safety guidelines
WARNING
The ionizer is designed solely for use in connection with
electronic balances. Do not use it for any other purpose.
Do not use the ionizer in any rooms with explosion haz-
ard present. Serial installation is not an explosion-proof
one.
Protect the ionizer from high ambient humidi-
ty/temperature, vapours and dust.
Ensure location free from water/oil.
Do not expose the ionizer to long-
term heavy moisture.
Any unexpected condensation (condensation of the air
humidity on the ionizer) may take place when a cold de-
vice is placed in a much warmer environment. In such
circumstances leave the ionizer, not connected to the
power supply, for ca. 2-
hours to ensure acclimatisation
to the ambient temperature.
When the ionizer
is on, do not touch any ion source, see
the label to the left.
Because a high-
voltage technology is used, handle the
ion source and outputs with care.
Do not dismantle and do not modify the ionizer.
Prevent any damage caused by falls, vibrations or im-
pact, see the label to the left.

ALJ-A03-BA-e-1810 4
Always use the OEM power adapter. The printed volt-
age value must comply with the local voltage.
Hazard of harm, ion source blades are very sharp.
The ionizer generates poisonous ozone, ensure suitable
ventilation.
Before you start any maintenance or cleaning, discon-
nect the ionizer from the power supply.
Always disconnect the unused ionizer from the power
supply.
CAUTION
Always maintain and clean the ionizer at regular inter-
vals.
●Ion source cleaning following 100 hours.
●Ion source replacement following 10,000 hours.
Operating the damaged ionizer can result in short cir-
cuit, fire or electric shock.
It is prohibited to switch it outdoors or in vehicles, this
shall invalidate any warranty.
If any electromagnetic fields are present, high readout
fluctuations are possible (mistaken weighing results).
Discharge the sample at the appropriate distance from
the balance.
The ionizer may heat slightly during the operation.
For improved
ionization results, switch the blower on.
This will make the sample discharge time shorter.

Installation

ALJ-A03-BA-e-1810 8
Power Choose the plug suitable for the country where the unit is
to be operated and plug in the power adapter.
The printed voltage value must comply with the local volt-
age.
Always use the original power adapters by KERN. To use
any other products, you need the consent of KERN.
Always connect the ionizer to the power adapter when the
device is off.
6 Start up
•Switch the ionizer on, pressing button.
The ionizer is in the Continuous Mode, the working time is 8 hours. Red LED
is on. The ionizer will switch off automatically in 8 hours.
•Switch the ionizer on, pressing button.
The ionizer is in the Time Mode. The ionizer is on for 2 minutes, red LED is
flashing. The ionizer will switch off automatically in 2 minutes.
•When the ionizer is on, you can press any button to switch to another work
mode.

Applications
The io
nizer is designed solely for use in connection with
electronic balances!

Discharging solid objects or balance pans.
For improved ionization results, switch the blower on.
This will make the sample discharge time shorter.

Discharging powder samples. Discharging prevents
whirls, a problem for toxic samples.
If the samples easily whirl, switch the blower off.

Discharging weighed material, glass windproof protec-
tion or balance pans.
Place the ionizer near the balance.

Discharging beakers etc.
When
you shake the beaker with the powder sample, the
powder will deposit on the inner beaker wall. This will be
prevented by discharging the beaker.

7 Maintenance, service, disposal
Cleaning
WARNING
Disconnect the device from the power sup-
ply before you start cleaning.
Do not dismantle the ionizer.
Do not use any aggressive cleaning agents (solvents etc.)
for cleaning. Use solely a cloth with a mild soapy water.
The liquid must not penetrate inside the device, use a soft
cloth to wipe the device dry after cleaning.
Keep the ion sources clean.
Maintenance, service
The device can be operated and maintained solely by ser-
vice technicians trained and authorised by KERN.
Disconnect the device from the power supply before you
open it.
Disposal The packaging and device should always be disposed in
accordance with the national or regional law in the location
where the device is used.
