Ambient conditions
• The systems are designed for ambient temperatures
during operation between +10°C and +40°C. Check the
maximum temperatures.
Operating conditions
➨ The devices are not suitable to aspirate:
- unstable substances
- substances which react explosively under impact
(mechanical stress) and/or when being exposed to
elevated temperatures without air,
-self inammable substances,
- substances which are inammable without air and
- explosive substance
➨The devices have no approval for operation below
ground.
+The pumps are not suitable for aspiration of dust.
• Take into consideration interactions and chemical
reactions of the aspirated media.
• Ensure that the materials of the wetted parts are com-
patible with the aspirated substances, see section
”Technical data”.
If aspirating different substances, it is recommended
that the aspiration hose be purged prior to changing the
media in order to rinse out residues and to avoid reactions
of the substances with each other and with the materials.

Safety during operation
➨ Ensure that while operating the device no persons can
be endangered.
➨ Wear personal protection equipment.
➨ Comply with requirements when using infectious liq-
uids, pathogenic germs, toxic, radioactive or aggres-
sive substances.
➨Prior to operation check all relevant safety and health
requirements and determine the applicability of regula-
tory limitations prior to use if necessary.
➨ Comply with material safety data sheets and notes on
safe use of the manufacturer.
➨ Comply with the biosafety level of the laboratory.
➨ Use appropriate safety work materials and methods if
necessary, e. g., steam sterilization, sterilization indica-
tors or germicides. For notes concerning the steriliza-
tion of wetted parts, see the “Technical Data” section
and “Cleaning and decontaminating”. It is the user´s
responsibility to ensure effective sterilization.
➨ Never operate a defective or damaged device.
+Comply with applicable regulations when disposing of
chemicals. Take into consideration that chemicals may
be polluted.
+Use only OEM spare parts and accessories; other-
wise safety and performance of the equipment as well
as the electromagnetic compatibility of the equipment
might be reduced.
+ In case of leaks in the aspiration hose, aspirated sub-
stances might be released into the environment. Com-
ply especially with notes on operation and use.
Ensure that, in case of failure, the system will always re-
turn to a safe status. Provide appropriate protective mea-
sures (i.e., precautions which allow for the requirements
of the respective application) even for the case of failure
and malfunction.

Maintenance and repair
➨ Attention: The device might be contaminated with nox-Attention: The device might be contaminated with nox-
ious or otherwise dangerous chemicals that have been
aspirated during operation. Ensure that the device is
decontaminated before maintenance.
+Take adequate precautions to protect people from the
effects of dangerous substances if contamination has
occurred. Wear appropriate safety-clothing when you
come in contact with contaminated components.
Ensure that maintenance is done only by suitably trained
and supervised technicians. Ensure that the maintenance
technician is familiar with the safety procedures which re-
late to the products processed by the system.
In order to comply with law (occupational, health and safe-
ty regulations, safety at work law and regulations for en-
vironmental protection) vacuum pumps, components and
measuring instruments returned to the manufacturer can
be repaired only when certain procedures (see section
”Repair - Maintenance - Return - Calibration”) are fol-
lowed.
