Cleaning the air filter of the compressor

CAUTION
To clean the air filter, the operating panel must be opened. The op-
erating panel may only be opened by a qualified electrician.
The air filter has the task of protecting the compressor from particles
and contamination. Drawn-in particles collect in the air filter so that
cleaning is required each quarter.
To clean the filter, carry out the following steps:
1 Open the door of the control unit housing.
2 Switch off the PurCon IS at the mains switch and pull out the
mains plug.
WARNING
Touching the electrical lines inside the control unit can result in
danger to life from electric shock. Before opening the operating
panel of the instrument, switch it off at the mains switch and pull
out the mains plug.
3 Open the operating panel and pull it down.
