Special safety instructions regarding this machine
Installation, site of Installation
and start-up
• Install unit only on adequately sta-
ble and non-combustible surface.
• Because of the wax vapours, install
the furnace under a chimney stalk
as far as possible. Always dis-
charge vapours outdoors.
• Only use the furnace in dry rooms.
• There must not be any combustible
objects in the area near the fur-
nace.
• There must not be any highly flam-
mable or explosive gas, liquids or
solid material in the same room as
the furnace.
• Remove transport protection
device from the mould chamber pri-
or to start-up!
Danger due to electric shock
• Always connect the furnace to a
separate circuit with 16-ampere
fuse protection.
• The machine is subject to the provi-
sions of class of protection I and
may only be connected to properly
grounded power sources.
• Use the rear plug only for connect-
ing the Regulus furnace suction
extraction unit (200-240 V).
Hazards from formation of dust!
• Parts of the insulation contain carci-
nogenic ceramic fibres that may be
released during servicing work. Use
gas mask type FFP 2 EN 149:2001
for servicing work with dust genera-
tion.
Burn hazard from hot parts!
• Wear protective clothing (protective
apron), safety shoes, safety gog-
gles and protective gloves.
• Only touch the hot furnace door at
the handle.
• Move hot moulds only with suffi-
ciently long tongs.
• Let the unit cool down until it is
warm to the touch before carrying
out any care, maintenance or clean-
ing work.
Hazard from 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 temper-
ature. 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 materi-
als, the Regulus furnace extraction
system (REF 25750) must be
installed.
• Regulus must be set to continuous
operation (→ page 39).
