6.1
Inspection and maintenance
In order to ensure the operational safety and reliability of your treatment
center and to avoid damage due to natural wear,
annual
inspection and
maintenance must be performed on your treatment center. This is done by an
authorized service engineer 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 maintenance work performed is
additionally recorded by the service engineer in the "Installation Report/
Warranty Passport". This document is part of the "Maintenance Manual".
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.
Hence it is 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. isolation defects). This is done
by an authorized service engineer from your dental depot, most practically
together with the work to be performed according to "Inspection and
maintenance" [
.
Safety tests must also be performed and documented during initial startup,
after extensions/upgrades (conversion) of your treatment center and after
repair work which might affect the electrical safety of the system.
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 engineer.
NOTE:
The treatment center must not be operated if it has failed to pass the safety
tests!
