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

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.

6
Safety
The installation, commissioning, operation and maintenance of the UV system must be
performed by trained and authorised personnel at all times. These appropriately qualified
personnel must have read and understood the relevant sections of this Manual, and the
safety-relevant sections in particular.
If in any doubt, please contact your specialist dealer or the head office of the
manufacturer UME GmbH. Full contact details are provided at the front of the
document.
Before opening or installing the system, ensure it is not connected to power or pressure
lines.
Before cleaning, maintenance or replacing machine parts, isolate the system from all
power sources.
Always follow the operating instructions and comply with the permissible technical
specifications that are appropriate for the specific application.
Always observe occupational safety and accident prevention regulations, and comply
with any other generally recognised health and safety at work standards.
Before commissioning the UV system, ensure that all of the safety-related requirements
have been fulfilled and that safety mechanisms are in working order.
The UV system must only be used under the operating conditions for which the system
has been specifically designed (flow rate, SAC, etc.).
The UV system must be taken offline immediately if components are damaged or are not
in proper working order. All structural or technical modifications to the UV system are
PROHIBITED.
2.1.3 Safety instructions
Potential risks for personnel and/or the UV system itself are listed, assigned to the
respective sections in this Manual and marked with these symbols.
See - “Explanation of symbols”.
Risks are assigned to one of two categories:
UV-related risks = hazard arising fro UVC radiation
Danger to health and life if the appropriate safety precautions are not
followed.
Non-UV-related risks = hazard arising fro work with electrical power or other
achine handling risks

3. Intended use
The ABO
®
ultraviolet systems deactivate microorganisms, like germs, viruses and
yeasts in the water. The system works efficiently only if clear free from iron and
manganese water is supplied. The function is guaranteed only within the limits of the
technical data of the device. ABO
®
UV-system UV-irradiation devices can be installed
directly into the water supply pipe. The System should be installed in the supply directly
before any ancillary distribution pipe work and possible storage reservoirs
3.1.1. Technical ethod
UV-disinfection is a process that takes place when water flows through the reactor
chamber. Microorganisms are exposed to UVC-irradiation and will be deactivated within a
few seconds. This means the cells photochemical reactions are released which inhibit
further cell division and render the microorganisms harmless.
The advantages of the procedure are
No addition of chemicals
No formation of harmful by products
Deactivation of microorganisms takes place for a few seconds

The UV systems uv matic 25 is for water temperatures 2-35 °C and the UV systems uv
matic 35 maximum 55 °C designed for continuous operation.
In addition, a continuous water flow at the specified rate is required for optimal
operation.
Please see the data sheet for your specific model.
During fluctuating operating times, please monitor the reactor temperature to avoid
damage to the equipment and associated pipe work.
The efficiency of the UV-device is determined by the UV-intensity in the reactor. This
decreases during operation by lamp ageing or deposits on the inner quartz tube. This
also applies to unstable UV-transmission turbidity values, air temperatures or lower
throughputs.
