13 Maintenance and Service
DANGER
Disconnect the ashing device from the mains during all maintenance work (pull out the
plug) and ensure that the device cannot be switched on inadvertently.
In order to guarantee operational safety, the ashing device must be inspected every 4 years at least
by an electrician from your Service Centre to ensure that it is in good working order.
Other maintenance is generally limited to regular cleaning.
13.1 housing
The housing can be cleaned on the outside with a damp cloth.
13.2 Sample chamber
Clean the sample chamber with a vacuum cleaner after taking out the parts inside (sample plate,
crucible, balance pan). Take care of the sensitive insulating and heating radiators. Avoid damage with
the suction tube.
NOTE
The high temperatures may cause cracks to appear in the insulation inserts. This is normal.
