Check the unit for any damages immediately after opening
the packaging. It is important that damage incurred during
transit is determined and reported immediately. If this is the
case, a full statement of facts must be made immediately
(and reported to the post office, railway or transport firm).
It is advisable to keep the original packaging for future transport.
4.1
Location of unit
The unit must be erected on a stable, clean and even surface.
For safety reasons and to ensure sufficient cooling in the
electronic compartment, the side walls of the unit must be
placed at least 30 cm away from the walls or other objects.
No containers, chemicals or other appliances should be placed
behind a unit.
4.2
Power connections
Check that the voltage of the socket is identical to the voltage
specified on the unit plate. Only connect the Melting Point
Unit to a plug which is earthed. External couplings and exten-
sion cables must be earthed (3-contact couplings, cables and
connectors). Any interruption of the earth wire is prohibited.
Risks caused by possible internal defects are thus prevented.
4.3
Mounting of accessoires
The sample holders of glass are inserted into the opening of
the housing cover.
The glass sample holders protect the apparatus from dust
and smaller particles and the operator from contact with electric
parts.
Therefore, the apparatus should never be operated without
the sample holders inserted.
