Precautions
High temperature
Although this instrument has been built to be very safe, it is still capable of
reaching temperatures up to 1200ºC. Care must be taken in order to avoid
touching hot surfaces.
Even though crucibles and molds are supposed to be cool at the end of a fusion
cycle, in order to avoid risks of burns, use appropriate gloves, laboratory tongs or
some other adapted tool to manipulate the crucible, mold and glass disk.
User is advised that this instrument remains very hot for a long time, even after
turning it off.
High voltage
This instrument is powered by 240 Volts AC. Although the elements are
interlocked with a safety device that removes power when opening the furnace
door, reasonable precautions must be taken.
Disconnect power cord before attempting any cleaning, maintenance or repair
operation.
Be careful that no liquid infiltrate into the unit's casing.
Acid spills
When making solutions, user is strongly discouraged to use glass beakers, as acid
spills in instruments are dangerous and not covered by warranty. Use only
unbreakable PTFE beakers; otherwise, there is a risk of user injury, due to flying
glass shards or acid splatter.
Heavy instrument
It is advisable that at least two persons carry this instrument to avoid injuries. Do
not drop instrument.
Crucible installation
To ensure safe operation, proper installation of the crucibles needs to be checked
by the user before each fusion. See page 27, Crucible installation, for detailed
instructions.
Damaged / dirty holders or platinumware
Never run a fusion if platinumware or their holders are damaged or soiled.
Replace damaged items or clean dirty parts immediately.
