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.
If the furnace head is replaced with a furnace head from another Programat CS4, calibration is required.
7.3 Cleaning
The furnace may only be cleaned when it is cool, since there is a burn hazard. Do not use any cleaning solutions.
Disconnect the furnace from the power source before cleaning.

harmless and do not influence the function of the furnace in a nega-
tive fashion.
