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
laboratories. 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 muffle
– Insulation material
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 S1, 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.
The following parts have to be cleaned from time to time:

line cracks on the surface of the insulation are harmless and do not
influence the function of the furnace in a negative fashion.
