Safety Notes
Basic Operating Precautions
These operating instructions describe Fisher Scientific low temperature incubators.
Fisher Scientific low temperature incubators have been manufactured to the latest state of the
art and have been tested thoroughly for flawless functioning prior to shipping. However, the
low temperature incubator 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:
• Never step into the unit.
• Fisher Scientific low temperature incubators must be operated by adequately trained and
authorized professional personnel.
• Fisher Scientific low temperature incubators 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 decontamination measures to be employed for the low temperature incubator and
the accessories used with it,
• the safety precautions to be taken when processing specific agents,
• the measures to be taken in case of accidents.
• Repair work on the low temperature incubator 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 low temperature incubator 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 Fisher Scientific International, LLC immediately for your own
safety.

Safety Notes
Operational Safety Rules
1-2 Peltier Low Temp. Incubators Fisher Scientific
Operational Safety Rules
The following rules must be heeded when working with Fisher Scientific low temperature
incubators:
• Observe the sample weight limits specified for your Fisher Scientific low temperature
incubator as a whole and its shelving in particular; see “Technical Data” on page 13-1.
• 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 Fisher Scientific low temperature incubator 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 every six months 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 Fisher Scientific low temperature incubator.
• The tempering of defined substances or materials with higher moisture content can result
in increased condensation in the chamber. Measures on page 6-2 must be observed.

Fisher Scientific International, LLC warrants the operational safety and functions of the
Fisher Scientific low temperature incubators only under the condition that:
• the low temperature incubator is operated and serviced exclusively in accordance with its
intended purpose and as described in these operating instructions,
• the low temperature incubator is not modified,
• only original spare parts and accessories that have been approved by Thermo Scientific are
used (third-party spares without Fisher Scientific International, LLC approval void the
limited warranty),
• inspections and maintenance are performed at the specified intervals,
• an operation verification test is performed after each repair activity.
