Ivoclar Vivadent Quick - Manual (Page 13)

This chapter describes the user maintenance and cleaning
procedures. All other tasks must be performed 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 fre-
quency of use and the working habits of the users. For that rea-
son, the recommended times are only approximates.
Disconnect power before maintenance and cleaning,
since there is a risk of electrical shock.
This apparatus has been developed for typical use in the
dental laboratory.
If the product is used in a production facility, for industrial appli-
cations, or in continuous firing operation, premature ageing of
certain spare parts have to be expected.
These spare parts are e.g.:
– Heating muffle
– Insulation material
– Lamps
These spare parts are not covered by the warranty.
Please also observe the shorter service and maintenance
intervals.
