Anti-condensation heating
WARNING
Explosion hazard when repairing the anti-condensation heating
If repairs to the anti-condensation heating are not carried out correctly, e.g. if unauthorized
or untested spare parts are used, explosions can occur when the machine is operated in an
explosive atmosphere. This can result in death, serious injury or material damage.
The anti-condensation heating must be repaired and the necessary routine testing that
follows repair must always be undertaken by experts from the Service Center (Page 143),
as this work requires extensive specialist knowledge. Only authorized and tested spare parts
may be used.
