7. Maintenance, Cleaning, and Diagnosis

This chapter describes the user maintenance and cleaning procedures
for the Programat EP 3000/G2. Only those tasks are listed that may
be performed by dental professionals. All other tasks must be per-
formed by qualified service personnel at a certified Ivoclar Vivadent
Service Center.

7.1 Monitoring and maintenance

The time for these maintenance procedures depends on the
frequency of use and the working habits of the users. For that
reason, the recommended times are only approximations.

This furnace has been developed for typical use in dental

laboratories. If the product is used in a production
enterprise, for industrial applications, and for continuous
use, premature ageing of the expendable parts has to be
expected.

The expendable parts are as follows:
– Heating muffle
– 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,
subsequent temperature calibration is required.
