Nautilus T
Special safety instructions regarding this unit
Installation
l The unit is categorised under protection class 1 and may only be connected to properly earthed power
sources (earth contact sockets).
l The unit has been set ex works for connection to a 230 V supply. The transformer (ref. 17800) must be
used for other voltages (200 to 240 V). The transformer must only be connected by qualified electricians.
l When laying cables and hoses, ensure that they are protected from hot components (e.g., moulds).
l The cooling water temperature must never drop below 10°C (50°F). Otherwise condensation water
may land on the hot moulds and vaporize explosively.
Hazards due to electromagnetic radiation
l Persons with electronic implants (for instance, pacemakers) may not remain in the same
room in which the ready-to-operate machine is located.
l The warning signs provided (symbol: "pacemaker") are to be placed at the entrances to the
room in which the ready-to-operate machine is located.
Danger of burns due to hot parts!
l Wear protective clothing (protective apron), safety shoes, safety goggles and protective gloves.
l Heat-resistant gloves must be worn when holding the handles of the crucible.
l Only open the lower chamber to move the moulds. Otherwise keep it closed.
l Always use mould tongs to move moulds and hot crucibles.
l Touch hot crucible inserts and hot cast metal parts only with forceps.
l Place hot parts only on a fireproof surface.
l Do not touch the viewer window in the upper chamber as this gets hot during operation of the unit.
l Carry out maintenance and cleaning work prior to casting or once the unit has cooled down.
Danger of deflagration
Ensure alloys, crucible and crucible inserts do not become contaminated. Oil or fat impurities may evaporate
explosively during the casting process.
Danger from waste gases
Ensure there is adequate ventilation in view of the waste gases arising during the casting of dental alloys.
Maintenance of safety-relevant components
The unit has been designed for a service life of 10 years from the date of manufacture. No liability is accepted
for damages arising from operation of the unit after this period.
Safety-relevant components must be checked regularly and replaced as required. This work must be carried
out solely by BEGO customer service or by repair centres authorised by BEGO customer service. To that end,
users are recommended to take out a maintenance agreement covering annual checks (or checks after every
10,000 castings) and a check after five years (or after 50,000 castings).
