1.2 Intended Use
The Vacuum & Pressure Casting Unit VPC pure is designed for casting
jewelry moulds in flange flasks or cylindrical flasks or to grain metal in
the granulating station.
The printing system is designed for temperature-controlled interiors
(→Chapter 11). Proper use requires compliance with all information in
this manual.
Any use going beyond the intended use or otherwise is deemed to be
improper. The operator is exclusively liable for any resulting damage.
Use contrary to the intended use includes, but is not limited to the
following actions:
–Operation within potentially explosive areas
–Operation with explosion-hazardous materials
–Outdoor operation
–Operation in tropical climates
–Operation in wet, damp rooms
–Operation without sufficient instruction
–Operation without mandatory safety equipment
–Operation with non-approved spare parts
–Operation with defective or modified safety devices
–Removing or modifying attached safety markings
–Improper conversions, modifications, repairs, and maintenance
1.3 Safety Devices
WA RN IN G!
Danger with non-functioning or dismantled safety
devices!
Safety devices serve to ensure safety during operation
and are not allowed to be removed, changed, or
bridged. Improperly functioning or removed safety
devices can lead to injuries.
–Safety devices are not allowed to be removed,
changed, or bridged during operation and an
active power supply of the machine.
–The safety devices must be removed only when
the machine has been switched off and is
disconnected from the power supply.
–All safety devices need to be checked for their
functionality each time the machine is turned on.
–If the safety devices are not functioning correctly,
the operation must be stopped immediately.
Defective safety devices need to be repaired or
replaced immediately.
The machine is equipped with the following safety devices:
–Lockable main switch
–Red stop button (Attention! No emergency shutdown function!)
–Security covers in the machine

1.4 Attached Safety Markings
WA RN IN G!
Danger from illegible signs!
Over time, labels and signs may become dirty or
otherwise unrecognizable, so that dangers cannot be
detected, and necessary operating instructions cannot
be followed. Thereby a risk of injury arises.
–All safety, warning and operating instructions
must always be in a legible state.
–Damaged labels and signs must be renewed.
The following labels and signs are in the work area. They refer to their
immediate environment.
No access for persons with pacemakers
or implanted defibrillators
The machine marked with this symbol can emit an
electromagnetic field. The machine must not be operated
by persons with pacemakers or implanted defibrillators.
Live Components
The areas marked with this symbol can be live. Work in
these areas may only be carried out by qualified
electricians.
Hand Injuries
The lid/cover as well as both sides of the flask chamber
of the machine marked with this symbol consists of
moving parts. Work in these areas should be performed
always in awareness of moving parts. There is a danger
of hand injuries.
Hot Substances
The lid/cover of the machine marked with this symbol can
provide access to hot substances through its open state.
Work in this area should be performed always in
awareness of hot substances. There is a danger of
burning fingers/hands/body parts.
Live Components
The protective covers marked with this
combination of symbol and text protect the
operator from touching live parts during
operation. Work in this area may only be carried
out with a disconnected mains plug.
Live Components
The lid/cover marked with this
combination of symbol and text protects
the operator from touching live parts
during operation. Operating the
machine may only be carried out with
the inductor cover installed.

1.5 Residual Risks
The machine is manufactured according to the state of the art.
Nevertheless, residual risks remain, which require action. The following
lists the residual risks and the resulting behavior and measures.
1.5.1 Danger due to Magnetic Field
DA NGER!
Risk of injury or death of a person due to electro-
magnetic interferences!
During operation, an electromagnetic field could be
emitted and interfere with medical implanted devices
(pacemakers and implanted defibrillators). There is an
electrical hazard of electromagnetic interferences.
–The machine must not be operated by persons
with pacemakers or implanted defibrillators.
1.5.2 Danger due to Electrical Current
DA NGER !
Danger to life due to electric current!
Incorrect connection, insulation faults, foreign objects
(dust, liquid due to inappropriate installation
environment) or lack of grounding can lead to housing
parts being live. There is an imminent danger of
electrocution in the event of contact with live parts.
–Work on the electrical equipment may only be
carried out by qualified electricians and in
compliance with the relevant safety and VDE
regulations.
–Machines with damage to the power cord,
insulation or lack of earthing must be
disconnected from the mains immediately.
Repairs are to be made immediately.
–Before starting work on active parts of the
electrical equipment, a de-energized state must
be established and ensured for the duration of
the work.
–Fuses must never be bypassed or put out of
operation.
–Connect the mains plug to the nearest and
correctly grounded socket to the machine.
–Only operate the machine with the mains voltage
specified for the machine.
–The mains plug must be freely accessible at all
times as the machine is completely disconnected
from the mains in case of an emergency by
pulling the mains plug. (→Chapter 5)
–Disconnect the machine from the mains during
longer absences and during heavy weather.
–Keep moisture away from live parts. This may
lead to short circuiting.

1.5.3 Danger due to Hot Substances
WA RN IN G!
Risk of injury and burning due to hot substances!
During heating of the melting material, components
and the melting material inside the melting chamber
become very hot, and the operator may burn fingers/
hands/body parts when touching them. There is a
burning hazard of fingers/hands/body parts.
–Be aware of hot substances due to the intended
use of the machine.
–Never touch the crucible with bare fingers and
hands.
–Never locate your bare fingers and hands in the
area above the crucible during and after the
melting process.
–Never work below the crucible during the melting
process, hot liquid material could drop on your
bare fingers and hands.
–Do not work at the sealing rod while it is hot.
–Wear protective foundry gloves during operation
with the machine and hot substances.
1.5.4 Danger due to Hot Surfaces
WA RN IN G!
Risk of injury due to hot surfaces!
During heating of the melting material, the protective
covers may become hot, and the operator may burn
fingers/hands/body parts when touching them. There is
a burning hazard of fingers/hands/body parts.
–The protective covers will not reach a
temperature above 50°C.
–Nevertheless, be aware of hot surfaces due to
the intended use of the machine.
–Wear protective foundry gloves during operation
with the machine.
1.5.5 Danger due to Moving Parts
CA UT ION!
Risk of injury due to moving parts!
During automatic locking of the flask chamber, the flask
chamber will be lifted up towards the melting chamber
for vacuum processes. There is a crushing hazard of
fingers between both chambers during the closing
movement.
–Never insert fingers above the flask chamber
AND under the melting chamber, when pressing
the «Start»button.
