Safety Notes
Basic Operating Precautions
These operating instructions describe Heratherm ovens.
Heratherm ovens have been manufactured to the latest state of the art and been tested
thoroughly for flawless functioning prior to shipping. However, the oven may present
potential hazards, particularly if it is operated by inadequately trained personnel or if it is not
used in accordance with the intended purpose. Therefore, the following must be observed for
the sake of accident prevention:
• Heratherm ovens must be operated by adequately trained and authorized professional
personnel.
• Heratherm ovens must not be operated unless these operating instructions have been fully
read and understood.
• The present operating instructions, applicable safety data sheets, plant hygiene guidelines
and the corresponding technical rules issued by the operator shall be used to create written
procedures targeted at personnel working with the subject matter device, detailing:
• the safety precautions to be taken when processing specific agents,
• the measures to be taken in case of accidents.
• epair work on the oven must be carried out only by trained and authorized expert
personnel.
• The contents of these operating instructions are subject to change at any time without
further notice.
• Concerning translations into foreign languages, the German version of these operating
instructions is binding.
• Keep these operating instructions close to the oven so that safety instructions and
important information are always accessible.
• Should you encounter problems that are not detailed adequately in these operating
instructions, please contact Thermo Electron LED GmbH immediately for your own safety.

Safety Notes
Operational Safety Rules
1-2 Heratherm Thermo Electron LED GmbH
Operational Safety Rules
The following rules must be heeded when working with Heratherm ovens:
• Observe the sample weight limits specified for your Heratherm oven as a whole and its
shelving in particular; see “Technical Data” on page 13-1.
• Do not load the bottom of the interior workspace to avoid the risk of overheating any
samples placed there.
• Arrange the samples evenly throughout the work space, making sure not to place them
too closely to the interior walls to ensure a uniform temperature distribution.
• Do not load your Heratherm oven with substances that exceed the capabilities of the
available lab apparatus and Personal Protection Equipment to provide sufficient degrees
of protection to users and third parties.
• Check the door seal once a week for proper sealing performance and possible damage.
• Do not process any samples containing hazardous chemical substances that may be
released into the ambient air through defective seals or may cause corrosion or other
defects on parts of the Heratherm oven.
Warranty
Thermo Electron LED GmbH warrants the operational safety and functions of the
Heratherm ovens only under the condition that:
• the oven is operated and serviced exclusively in accordance with its intended purpose
and as described in these operating instructions,
• the oven is not modified,
• only original spare parts and accessories that have been approved by Thermo Electron
LED GmbH are used (third-party spares without Thermo Electron LED GmbH
approval void the limited warranty),
• inspections and maintenance are performed at the specified intervals,
• an installation verification test is performed on commissioning the oven for the first time
and repeated after each inspection and repair activity.
• The warranty is valid from the date of delivery of the oven to the customer.
