CARE, MAINTENANCE AND REPAIR
In order to ensure the long-term, proper functioning of the device, it must be regularly cleaned
and, if necessary, maintained. The maintenance requirement depends on the intensity of use
and the environment in which it is used. We generally recommend a visual inspection each
time before putting into operation. Furthermore, we recommend carrying out all the applicable
maintenance measures specified below once every 500 operating hours or, in the case of a
lower intensity of use, at the latest after one year. Warranty claims may be limited in the event of
defects resulting from inadequate maintenance.
CARE (CARRIED OUT BY USER)
WARNING! Before carrying out any care or maintenance, the power supply – and, if
possible, all device connections – must be disconnected.
NOTE! Improper care can lead to impairment of the device or even its destruction.
1. Housing surfaces must be cleaned with a clean, damp cloth. In doing so, ensure that no
moisture can penetrate into the device.
2. Air inlets and outlets must be regularly cleaned of dust and dirt. If compressed air is used,
make sure that damage to the device is prevented (e.g. fans must be blocked in this case).
3. Lines and plug contacts must be cleaned regularly and dust and dirt must be removed.
4. In general, no cleaning agents or abrasive agents may be used, otherwise the surface finish
may be damaged.
5. Devices must generally be stored dry and protected from dust and dirt.
