Maintenance
Brushless turbines are the most commonly used turbines. They allow maintenance-free continuous
operation and very high vacuums at reasonable costs.
6.1
Cleaning the device
Before cleaning the device, it is to be shut down and unplugged from the mains power supply.
The system housing is coated with a resilient varnish. It can easily be cleaned using a damp cloth
and a common household cleaning agent.
Do not use any solvents!
Make sure no cleaning water leaks into electric components nor into the ventilation slots.
In case you loosen filter modules for cleaning, make sure not to damage the seals and ensure
proper fit of the seals before putting the device back into operation.
Dry well with a dry cloth.
6.2
Filter-saturation indicator and filter replacement
For additional information on the filter-saturation indicator, please see chapter 5.1
Please note:
Particle filter must not be cleaned. They are to be replaced!
Activated-carbon/BAC filters are to be checked and replaced regularly. They are not shown on the
system’s filter monitoring – it is recommended to replace them at least once a year.
Danger!
The replacement of turbines or electric components must only be
performed by authorised specialists!
Caution!
When cleaning the device, proper protection equipment is to be worn in
order to prevent contamination with potentially harmful substances.
Caution!
Do not clean the filter! Beating out or blowing out with compressed air damages the
filter medium. As a result, contaminants will leak into the ambient air.
Caution!
The individual filter stages are to be checked regularly (at least once a week). If
required, they are to be replaced in order to ensure a consistent extraction performance and to
prevent any damage to the system. During the filter replacement, the extraction process must be
turned off and appropriate protective wear must be worn.
