FOCUS 4010/HT Dental Porcelain Furnace Page 10 Manual version 4.2.2013
3. Initial Operation
Before running any firing cycles the furnace must undergo an initial drying procedure to
remove any absorbed humidity that may have entered during transit.
The furnace firing procedure is a special drying cycle for the firing chamber, and it must be
carried out before you start using your furnace.
The procedure is mentioned here before the operating instructions, to remind you to read
the entire operations manual and then to run the initial firing procedure before working with
any program.
We highly recommend you to use a dry pump that is able to reach 720 mmHg
within 35-40 sec
