WARNING
Risk of injury due to insufficient training!
Appropriate training is required for the following maintenance steps to prevent injuries.
• Only authorised service personnel may carry out this maintenance step.
• Note the warnings and maintenance instructions at the beginning of this chapter!
Figure 6-6
• Switch off the machine and disconnect the mains plug. Remove the screws of the side panel. Remove
the side panel from the system (lift up and sidewards).
• Use only compressed air free of water and oil. Do not blow on electronic components directly. The ma-
chine fans may over-rev due to the compressed air and thus become damaged. Therefore, use a
screwdriver to block the machine fan mechanically. Please note: The strips of the heat exchanger be-
hind the machine fans must not be damaged by the screwdriver.
Figure 6-7
• Blow out the heat exchanger using the fans.
• The dirt escapes through the openings in the side panel.
Follow official regulations on disposal!
• After cleaning, remove any mechanical blockages from the fans, close the machine in reverse order
and check according to applicable regulations.
