4. What If...
4.3 Repairs
Repairs may only be carried out by a certified Service Centre. Please refer to the addresses on the last page of
these Operating Instructions.
If repairs during the warranty period are not carried out by a certified Ivoclar Service Centre, the warranty will expire
immediately. Please also refer to the corresponding warranty regulations.
Unauthorized opening and removal of housing elements can expose voltage-carrying components. Plugs could
also be live. There is a risk of electric shock.
4.3.1 Changing the fuse
Fuses may only be changed if the furnace is switched off and the power disconnected:
– Put the mains switch on Position 0 and disconnect the power cord.
– Disconnect the power cord from the furnace.
– Open the fuse holder using a slotted screwdriver.
– Replace the fuse in accordance with the indications on the rating plate. Use only original or equivalent fuses!
– Secure the fuse holder with the screw.
– Reconnect the power cord.
4.3.2 Emergency opening of the furnace head
If the furnace head does not open when pressing the [Open furnace head] button and you want to e.g. remove a
completed restoration, you can open the furnace head mechanically.
Switch off the furnace and disconnect the power cord from the furnace.
There is a small hole on top of the furnace head. Insert a small slotted screwdriver into the hole. The furnace head can be
opened by turning the screwdriver.
Remove the restoration and close the furnace head. Please contact the After Sales Service.
Remove the object tray from the furnace in the same way before transport.
