Do not carry the furnace head by the cables, since the cables and
connections may be damaged.
The furnace head has an electric drive and must be operated by means of
the electronic controls. Never open the furnace head by hand, since the
mechanism will be damaged.
The furnace must not be operated if the quartz tube or the insulation in the firing chamber are damaged.
There is a risk of electric shock upon contact with the heating wire. Avoid damage of the insulation by contact
with the investment tongs or firing tongs.
Contraindication
Firing trays must not be placed in the area surrounding the firing table, since
this will obstruct the closing of the furnace head.
Foreign objects must not be placed on the furnace head or the air vents.
Make sure that no liquids or other foreign objects enter the air vents, since
this may result in an electrical shock.
Never use the furnace without a firing table.
