2.4 Operating conditions
Do not use the pumps if they are not in technically perfect
working order; pumps must be operated in accordance with
their intended use, with attention to safety and hazard consid-
erations, and in conformance with the operating instructions
at all times.
The pumps must only be operated in the fully assembled and
supplied condition.
Make sure that the installation location is dry and that the
pump is protected from rain, splash water, gushing water,
dripping water and other contamination.
Check the tightness of the connections between the pipes of
the application and the pump (or the connection of the pump)
at regular intervals. Leaky connections carry the risk of re-
leasing dangerous gases and vapors from the pump system.
The components that are to be connected to the pumps must
be designed according to the pneumatic data of the pumps.
2.5 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 3 Technical data [} 13]) with the
medium.
Only transfer gases that remain stable under the pressures
and temperatures that arise in the pump.
Upon breakage of the diaphragm and/or leaks, the transferred
medium mixes with the air in the surroundings and/or in the
pump housing. Make sure that a dangerous situation cannot
arise as a result.
When pumping hazardous media, follow the safety regula-
tions that apply for working with these media.
