7. Maintenance, Cleaning and Diagnosis
This chapter describes the user maintenance and cleaning procedures
for the Programat P300/G2. All the other tasks must be performed
by qualified service personnel at a certified Ivoclar Vivadent Service
Centre.
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.
monthly Vacuum hose
Firing chamber Check if there is condensate in the vacuum hose or firing chamber.
daily Firing chamber Check the quartz glass cylinder to make sure the quartz glass is not defective.
twice a
year Firing chamber Check temperature.
Use the temperature checking set to check and adjust the temperature in the
furnace.
weekly Keypad (10) Check the keypad for visible damage. If the keypad is damaged, it has to be replaced
by a certified Ivoclar Vivadent Service Centre.
weekly Sealing rims of the furnace
head (2) and the furnace base
(1) Check if the sealing rims of the furnace head and the furnace base are clean and
undamaged.
monthly Insulation (3) 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 hairline cracks on the
surface of the insulation are harmless and do not influence the function of the
furnace in a negative fashion.

What Part
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.
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.
7.2 Cleaning
The furnace may only be cleaned when it is cool, since
there is a burn hazard. Do not use any cleaning solutions.
The following parts have to be cleaned from time to time:
*Never clean with compressed air!
