Caution
Detergent can run off through the retentate nozzle.
In the case of drinking water or sensitive surface water, remove the out-
let tube from the retentate nozzle.
After the cleaning procedure has been completed, the PurCon supplies
a sufficient amount of permeate again.

Cleaning the air filter
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.
