WARNING
When, for technical reasons, it is necessary to work on instrument parts which might
involve an hazard (moving parts, components under voltage, and so on), the authorized Technical
Service must be contacted. This type of situations can be identified because access to these parts is
possible only by using a tool. The removable protective covers bear a warning symbol suggesting to
refer to the documentation accompanying the instrument. When a maintenance operation is
performed, the operator must have received proper training to carry out specific actions.
WARNING
When the instrument is switched off, consider that its does not cool down
immediately, but heat tends to concentration in the upper part of the furnaces area. It should be
made clear that it is better to cool down the furnaces first before switching off the instrument.
Switching it off means that the fan in the back does not remove the hot air concentrating at the top
and the surface thus becomes very hot. The openings provided for the chamber aeration will cause a
slow cooling of the same, which however, in the vicinity of the areas marked with the symbol “hot
surfaces”, might even reach temperatures higher than ambient temperature. Therefore in the
minutes immediately following the instrument switching off, the operator must consider this risk
and pay adequate attention during any maintenance operations following the use of the instrument.
