Maintenance and Inspection
In order to ensure the operational and functional reliability of your treatment unit and
to avoid damage due to wear and tear it is necessary to perform maintenance once a
year. Maintenance is carried out by an authorised technician of your specialist dealer or
a DKL CHAIRS technician.
The work steps to be performed and the parts to be replaced are specifi ed in the
document “Maintenance Log“. The tasks that were performed have to be entered in the
maintenance log, which is part of the medical devices logbook.
Safety Inspections
Dental units are designed in such a way that a fi rst fault does not present a hazard to
patients, operators or third parties. Therefore, it is important to detect such faults before
a second fault occurs, which may result in a hazard.
For this reason, safety inspections should be carried out every 3 years to detect
electrical faults in particular (e.g. faulty electrical insulation). These checks are carried
out by an authorised technician of your specialist dealer or a DKL CHAIRS technician.
The work steps to be performed are specifi ed in the document “Safety Inspections“. The
measured values have to be documented.
Safety inspections have to be carried out when putting your treatment unit into initial
operation, after expansion or retrofi tting activities on your treatment unit and after repair
jobs.The safety inspections are carried out in accordance with DIN EN 62353.
The treatment unit may only be operated when the safety checks have been passed.
