Filter saturation indicator and filter replacement

ensure a constant extraction level and prevent damage to the system. Only replace filters with the
extractor switched off and while wearing appropriate protective clothing.
Note:
• Particle filters must not be cleaned! They are replaced only!
• Activated carbon/BAC filters must be inspected regularly and replaced. They are not monitored by the filter
monitoring of the system.
