Maintenance by the service engineer

6.1

Inspection and maintenance

In order to ensure the operational safety and reliability of your dental
treatment unit and to avoid damage due to natural wear, annual
inspection and maintenance must be performed on your dental treatment
unit. This is done by an authorized service technician from your dental
depot.
As soon as the next maintenance call is due in less than 42 days, a
wrench symbol appears in the status line of the touchscreen after switch-
on. Below this symbol, the number of days until the maintenance deadline
are counted down (e.g. 13 d = 13 days). You should now contact your
dental depot and make an appointment.
The work steps to be performed as well as the parts which must be
replaced are specified in the document "Maintenance Certificate".
An overview of the inspection and servicing carried out is additionally
recorded by the service technician in the "Installation Book".
6.2

Safety checks

Medical equipment is designed in such a way that the first occurrence of
a fault does not create a hazard to the safety of patients, users or other
persons. It is therefore important to detect such faults before a second
fault occurs, which might then lead to safety hazards.
For that reason it is essential to perform safety tests every 2 years which
aim particularly at detecting electrical faults (e.g. defective insulation ).
This is done by an authorized service technician from your dental depot,
most practically together with the work to be performed according to
"Inspection and maintenance" [ → 261].
Safety tests must also be performed and documented during initial
startup, after extensions/upgrades (conversion) of your dental treatment
unit and after repair work which might affect the electrical safety of the
system.
Safety checks exist
WARNING
The dental treatment unit must not be operated if it has failed to pass the
safety tests!
The safety checks includes a visual inspection as well as measurements
of the protective ground wire connections and the equivalent leakage
currents.
The inspections and measurements to be performed are specified in the
"Maintenance Manual". The measured values must be documented there
by the service technician.
