Explanation of symbols
Notice
General information.
Warning
Important information or prohibitions to avoid causing damage.
Warning
Warns the user about dangerous electrical voltage.
This sign is used for activities involving system components carrying
live current.
Warning: UVC radiation
If your eyes are not protected, looking at UVC for only a few seconds
(and at a distance of several metres) is enough to cause a painful
inflammation, similar to the “arc eye” experienced when welding, noticed
only hours later. Irradiation of the skin for just a few minutes is enough
to cause serious sunburn.
Danger
Danger to health and life if the appropriate safety precautions are not
followed.

Cotton gloves can be supplied as accessories.
Mandatory
Safety goggles must be worn at all times to protect the eyes. Only pure
quartz glass is UV-C-permeable. Also offers protection against cleaning
agents.
Safety goggles can be supplied as accessories.
Mandatory
Danger of malfunctions/damage to the UV system if the appropriate
safety precautions are not followed.
2.1.2 UV light protection
During normal operation of the UV system, the UV emitters are completely enclosed and
no UV light can escape from the UV reactor. This means operating personnel cannot be
exposed to any danger from UV light.
When checking system functions, troubleshooting or performing maintenance and
servicing, it may be necessary for a live UV emitter to be less than fully enclosed. In
such cases, suitable protection for the skin and eyes – in particular – MUST be worn.
