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.
Disconnect power before cleaning.

7.3 Service note
When the service note appears for the first time, the furnace has already more than 1500 firing hours. If the service note is
acknowledged, is will reappear every 1000 firing hours.
Ivoclar Vivadent recommends to conduct a heater test after a certain number of firing hours and have the heating muffle
examined by Ivoclar Vivadent After Sales Service if necessary.
7.4 Stand-by
We recommend keeping the furnace head closed, especially if the temperature drops below 150°C. If the furnace head is
open, there is a risk that the insulation absorbs humidity and condensation water develops during firing. This negatively
affects the vacuum performance and, consequently, the firing results.
7.5 Power-saving mode
If the furnace is not used for longer periods of time, Ivoclar Vivadent recommends to activate the power-saving mode. With
the power-saving mode activated, individual components are switched off and the furnace temperature is reduced to 100°C.
7.5.1 Automatic power-saving mode
The automatic power-saving mode can be activated in the Settings menu.
If the power-saving mode is activated and the furnace head closed, this function is automatically started after 30 minutes,
if the furnace is on stand-by and no key is pressed during that time. The display shows the power-saving icon. Pressing any
key ends the automatically activated power-saving function.
7.5.2 POWER-SAVING key
The power-saving mode can be manually activated by pressing the POWER-SAVING key. This is only possible with the
furnace head closed and the furnace on stand-by. The display shows the power-saving icon. Pressing any key ends the
power-saving function.
