Pay attention to symbol ”hot surfaces” on the equipment (according to IEC 1010 rec-
ommendation).
☞ Adopt suitable measures to prevent any danger arising from the formation of hot
surfaces or electric sparks.
☞ Make sure ventilation is adequate if pump is installed in a housing or if ambient
temperature is elevated.
To the best of our knowledge the equipment is in compliance with the requirements of
the applicable EC-directives and harmonized standards (see ”Declaration of con-
formity”) with regard to design, type and model, especially directive IEC 1010. This
directive gives in detail conditions, under which the equipment can be operated safely
(see also IP degree of protection).
☞ Adopt suitable measures in case of differences, e. g. using the equipment out-
doors, installation in altitudes of more than 1000 m above mean sea level, conduc-
tive pollution or moisture.
The pumps have no approval for operation in or for pumping of potentially ex-
plosive atmospheres.
If pumping different substances, purge the pump with inert gas prior to changing the
pumped media in order to pump out residues and to avoid reactions of the pumped
substances with each other with and the pump material. Ensure that the materials of
the wetted parts are compatible with the pumped substances, see section ”Technical
data”.
Take into consideration interactions and chemical reactions of the pumped me-
dia.
The pumps are not suitable for pumping substances which may form deposits in-
side the pump.
☞ If there is a danger of the formation of deposits in the pump chamber (check inlet
and outlet of the pump) inspect the pump chamber regularly and clean if neces-
sary.
The pumps are not suitable to pump unstable substances and substances which
react explosively under impact (mechanical stress) and/or when being exposed to
elevated temperatures without air.
The pumps are not suitable to pump self inflammable substances, substances which
are inflammable without air and explosive substances.
The pumps are not suitable for pumping dust and have no approval for operation
below ground.
Ensure that the materials of the wetted parts are compatible with the pumped
substances, see section ”Technical data”.
☞ If residues can occur or if aggressive or condensable substances may enter the
product, install suitable protection (e.g. gas washing bottle).
☞ Adopt suitable measures to prevent the release of dangerous, explosive, corrosive
or polluting fluids.
☞ Take adequate precautions to protect people from the effects of dangerous sub-
stances (chemicals, thermal decomposition products of fluoroelastomers), wear
appropriate safety-clothing and safety glasses.
☞ Observe applicable regulations when disposing of chemicals which may be con-
taminated by pumped substances.
☞ The user must take suitable precautions to prevent any formation of explosive
mixtures in the expansion chamber. In case of a diaphragm crack, mechanically
generated sparks, hot surfaces or static electricity may ignite these mixtures.
Important note on working with condensable vapours:
☞ Before commencing evacuation, allow pump to reach operating temperature, make
sure that gas ballast valve remains open all times and do not permit vapour inlet
pressure to exceed the permitted maximum.
