Cleaning

ELECTRIC SHOCK
The LED modules work with low voltage but high current. This presents a relevant electrical hazard.
If moisture enters by way of cleaning and disinfecting agents, there is a hazard of short circuit and
electric shock.

Observe the following:

• Switch off the unit and unplug the power supply before cleaning.
• Disassembling the housing is not part of the operator's maintenance work.
• Do not use spray bottles – only use slightly moistened wipes.
