Special safety instructions regarding this unit
l Installation, site of installation and start-up
• Install unit only on adequately stable and non-combustible surface.
• Because of the wax vapours, install the furnace under a chimney stalk as far as possible. Always
discharge vapours outdoors.
• Only use the furnace in dry rooms.
• There must not be any combustible objects in the area near the furnace.
• There must not be any highly flammable or explosive gas, liquids or solid material in the same room as
the furnace.
• Always connect the furnace to a separate circuit with 16-ampere fuse protection.
• The unit is subject to safety class I and may only be connected to properly grounded power sources.
• Use the rear plug only for connecting the Regulus furnace suction extraction unit (200-240 V).
• Remove transport protection device from the mould chamber prior to start-up!
l Risk of burns due to hot parts
• Wear protective clothing (safety apron), safety shoes, safety goggles and safety gloves.
• Only touch the hot furnace door at the handle.
• Move hot moulds only with sufficiently long tongs.
• Let the unit cool down until it is warm to the touch before carrying out any care, maintenance or
cleaning work.
l Shock heat investment materials
So-called shock heat investment materials are not heated up slowly, but are placed in a furnace that has
been preheated to the final temperature. As a result, the modelling material burns atypically, i.e., if the
furnace door is opened, inflowing oxygen can cause a darting flame!
• Place all moulds in the furnace within 10 seconds - then keep the furnace door closed for 15 minutes!
• For shock heat investment materials, the Regulus furnace extraction system (Ref. 25750) must be
installed.
• Regulus must be set to continuous operation (see page 12).
l Servicing work
Parts of the insulation contain carcinogenic ceramic fibres that may be released during servicing work.
Use gas mask type FFP2 – EN 149:2001 for servicing work with dust generation.
