10.6 Anti-condensation heating
WARNING
Explosion hazard due to improper maintenance
If repairs to the anti-condensation heating are not carried out correctly, e.g. if unauthorized or
untested spare parts are used, this can result in explosions during operation in a potentially
explosive gaseous atmosphere. This can result in death, serious injury or material damage.
• Repairing and mounting the anti-condensation heating and the subsequent routine testing
must always be undertaken by experts from the service center (Page 12), because this work
requires extensive specialist knowledge.
• Only authorized and tested spare parts may be used.
10.7 Groups of parts
A distinction is made between the following groups of parts:
Spare parts
Spare parts are machine parts that can be ordered during the production time - and for a
further 5years after discontinuation of production. These parts should be replaced only by
authorized service or modication partners.
Repair parts
Repair parts are machine parts that can only be supplied during the active production of
the machine (until the product discontinuation). Repair parts are parts used for the repair
or modication of the current products. These parts should be replaced only by authorized
service or modication partners.
Standardized parts
Standardized parts are machine parts that can be commercially obtained with the
necessary dimensions, materials and surface nish. A detailed list can be found in Chapter
"Standardized parts".
Other parts
Other parts are small parts required to complete the exploded drawing. These parts cannot
be supplied as individual spare or repair parts. Delivery as assembled units, for example as
complete terminal box, is possible on request.
