7. Maintenance, Cleaning, Diagnosis
This chapter describes the user maintenance and cleaning procedures for the Programat P710. Only those tasks are listed
that may be performed by dental professionals. All other tasks must be performed by qualified service personnel at a
certified Ivoclar Vivadent Service Centre.
7.1 Monitoring and maintenance

reason, the recommended times are only approximations.

noise.

This furnace has been developed for typical use in dental laboratories. If the product is used in a production
enterprise, for industrial application and for continuous use, premature ageing of the expendable parts has to be
expected. The expendable parts are, e.g. the heating muffle, furnace head seal or the insulation material.
Expandable parts are not covered by the warranty. Please also observe the shorter service and maintenance intervals.
In general, the furnace head should not be replaced since the components (furnace head and furnace base) have
been coordinated with each other. However, if the furnace head must be replaced for maintenance reasons, sub-
sequent temperature calibration is required.
