Monitoring And Maintenance; Cleaning - Ivoclar Vivadent Programat CS4 Operating Instructions Manual

7.2 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 practices. If the product is used in a production enter-
prise, for industrial applications and for continuous use, premature ageing of the expendable parts has to be
expected.
The expendable parts are as follows:
– Heating elements
– Insulation material
These expendable parts are not covered by the warranty. Please also observe the shorter service and maintenance intervals.
What:
Check all plug-in connections for correct fit.
Check if the furnace head opens smoothly and without excessive
noise.
Check if the thermocouple is straight and in the right place.
Check the insulation for cracks and damages. If the insulation is worn
down it has to be replaced by a certified Ivoclar Vivadent Service
Centre. Fine hairline cracks on the surface of the insulation are
harmless and do not influence the function of the furnace in a nega-
tive fashion.
Check the membrane-sealed keypad for damage. If the keypad is
damaged, it has to be replaced by a certified Ivoclar Vivadent Service
Centre.
Check temperature
Use the temperature checking set to check and adjust the
temperature in the furnace.
If the furnace head is replaced with a furnace head from another Programat CS4, calibration is required.
