1 Introduction
Your Ionizer Module is an accessory for METTLER TOLEDO analytical balances. The ionizer produces a corona of
ionized air, providing ions of the opposite polarity to neutralize static charges in the object being weighed.
The guidelines stated in the Reference Manual of the METTLER TOLEDO balance connected to your ionizer also
fully apply to your Ionizer Module.

2.2 Product-specific safety notes
Responsibilities of the instrument owner
The instrument owner is the person holding the legal title to the instrument and who uses the instrument or
authorizes any person to use it, or the person who is deemed by law to be the operator of the instrument. The
instrument owner is responsible for the safety of all users of the instrument and third parties.
METTLER TOLEDO assumes that the instrument owner trains users to safely use the instrument in their workplace
and deal with potential hazards. METTLER TOLEDO assumes that the instrument owner provides the necessary
protective gear.
Intended use
Your ionizer is an accessory for METTLER TOLEDO analytical balances and is used to discharge electrostatically
charged objects. Use the ionizer exclusively for this purpose. Any other type of use and operation beyond the
limits of technical specifications without written consent from Mettler-Toledo GmbH, is considered as not
intended.
Intended use also includes compliance with all the instruction in this Reference Manual and the Reference
Manual of your balance.
WARNING
Malfunction of cardiac pacemakers
− Persons with cardiac pacemakers must maintain a safety distance of more than 50cm from
the Ionizer.
CAUTION
Injury due to spiky emitters
− Do not touch the emitter pins directly.
NOTICE
Reduced performance due to inert gas
An inert gas atmosphere or an inert gas purging system influences the transfer of ions and will
result in reduced ionization efficacy.
− Only use the Ionizer Module in air.

Check the package, the packaging elements and the delivered components for damages. If any components are
damaged, please contact your METTLER TOLEDO service representative.
3.2 Installing the Ionizer Module
NOTICE
Damage to the instrument due to the use of unsuitable tools
Using a screwdriver or the like to remove the module-compartment cover can damage the
instrument.
− Use the wedge-shaped tool provided with the Ionizer Module to remove the modulecompartment cover.

5 Maintenance
5.1 Cleaning
WARNING
Electric shock
1 The balance must be disconnected from the power supply before maintenance.
2 Ensure that no liquid comes into contact with the AC adapter.
3 Never open the balance, terminal, ionizer or AC adapter – they contain no internal components
that can be cleaned, repaired or replaced by the user.
4 Do not reconnect the balance until the cleaned parts are dry.

CAUTION
Injury due to spiky emitters
− Do not touch the emitter pins directly.
Clean the ionizer once a month with a soft brush or with ethyl alcohol and a lint-free cloth.
1 Clean the insulation, white PTFE, around the emitter pin and the emitter pin itself.
Note Avoid touching this area with fingers to prevent contamination.
ð PTFE is white again.
2 Check that no ethyl alcohol is left on the ionizer.
Note
Please contact your METTLER TOLEDO service representative for details of the available service options.
