7. Maintenance, Cleaning, and Diagnosis
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.
This chapter describes the user maintenance and cleaning procedures
for the Programat EP 5000/G2. All the 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
Expendable parts are not covered by the warranty. Please also
observe the shorter service and maintenance intervals.
What Part When
Check all plug-in connections for correct fit Var. external connections weekly
Check if the furnace head opens smoothly and without excessive noise. Opening mechanism monthly
Check if the thermocouple is straight and in the right place. Thermocouple (4) weekly
Check the insulation for cracks and damages. If the insulation is worn down
it has to be replaced by a certified Ivoclar Vivadent Service Center. Fine hair-
line cracks on the surface of the insulation are harmless and do not influ-
ence the function of the furnace in a negative fashion. Insulation (3) monthly
Check if the sealing rims of the furnace head and the furnace base are clean
and undamaged. Sealing rims of the furnace head (2)
and the furnace base (1) weekly
Check the keypad for visible damage. If the keypad is damaged, it has to be
replaced by a certified Ivoclar Vivadent Service Center. Keypad (10) weekly
Check temperature.
Use the temperature checking set to check and adjust the temperature in
the furnace. Firing chamber twice a year
Check the quartz glass cylinder to make sure the quartz glass is not
defective. Firing chamber daily
Check if there is condensate in the vacuum hose or firing chamber. Vacuum hose
Firing chamber monthly
