Avoid the release of hazardous, toxic, explosive, corrosive,
harmful or environmentally hazardous gases or vapors, e.g.
by using suitable laboratory equipment with fume hood and
ventilation control.
3.4 Operating conditions
Only use the vacuum systems in perfect technical condition,
for their intended purpose, safely and aware of the dangers
and in observation of the operating instructions.
Only vacuum systems that are fully assembled and in the
condition as delivered are allowed to be operated.
Make sure that the installation location is dry and that the vac-
uum system is protected against rain, spray water, splash wa-
ter and dripping water as well as from other contamination.
Regularly check the tightness of the connections between the
piping of the application and the vacuum system (or the pneu-
matic connection of the vacuum system). Leaky connections
carry the risk of releasing dangerous gases and vapors from
the pump system.
3.5 Media
Before transferring a medium, check whether the medium can
be transferred danger-free in the specific application.
Take note of any change in the state of matter (condensation,
crystallization).
Before using a medium, check the compatibility of the media-
contacting components (see 4 Technical data [} 16]) with the
medium.
Only transfer gases that remain stable under the pressures
and temperatures that arise in the vacuum system.
Upon breakage of the diaphragm and/or leaks, the transferred
medium mixes with the air in the surroundings and/or in the
vacuum system housing. Make sure that a dangerous situa-
tion cannot arise as a result.
When pumping hazardous media, observe the safety regula-
tions for the handling of said media.
Note that the vacuum system is not designed to be explosion-
proof.
