10.4.1 

Cleaning during Operation 

Keep the system always clean during operation. Only a clean ozone system guarantees 
proper operation: 

•

 

Keep the exterior of the system clean (do not open the system). 

•

 

Keep the floor clean.  

•

 

Avoid tools, packing material, chemicals etc. lying around.  

 

10.4.2 

Cleaning with the System Disconnected form Power Supply 

Preparation 

•

 

Ensure the system is isolated from the power supply. 

•

 

Secure the system against unintended restart. 

•

 

Close all openings to prevent cleaning agent from ingressing 
into the system.  

•

 

Cover all system components which are not allowed to contact 
cleaning agent. 

 

Cleaning 

•

 

Use a lint free cloth moistened with alcohol or a soft brush.  

•

 

Use a vacuum cleaner to remove dust. 

•

 

Do not remove any safety devices when cleaning the system. 

 

After cleaning 

•

 

Check all cables for loose connections and damage. 

•

 

If necessary, retighten loose connections. 

•

 

Remove the protective covers or lockings from the openings 
previously covered for cleaning purposes.
