You should always consider the explosion group AND
temperature class together:
You are safe in areas at risk from explosion with all the
gases listed in the table with equipment approved for
explosion group IIC and temperature class T4.
Equipment approved for explosion group IIB can also be
used for explosion group IIA – not for explosion group
IIC.
Equipment approved for temperature class T3 can also
be used for temperature classes T2 to T1 – not for tem‐
perature class T4.

CAUTION!
These operating instructions include notes and extracts
from German regulations relating to the operator's scope
of responsibility. This information does not discharge the
operator from his responsibility as an operator and is
intended only to remind him or make him aware of spe‐
cific problem areas. This information does not lay claim
to being complete, nor applicable to every country and
every type of application, nor to being unconditionally
up-to-date.
The following signal words are used in these operating instructions to
denote different severities of danger:
Signal word Meaning
WARNING Denotes a possibly dangerous sit‐
uation. If this is disregarded, you
are in a life-threatening situation
and this can result in serious inju‐
ries.
CAUTION Denotes a possibly dangerous sit‐
uation. If this is disregarded, it
could result in slight or minor inju‐
ries or material damage.
The following warning signs are used in these operating instructions to
denote different types of danger:
Warning signs Type of danger
Warning – high-voltage.
Warning – danger zone.
nOnly use the pump to meter liquid feed chemicals.
nOnly pumps with the identity code option "Multi-layer safety diaphragm
with visual rupture display" and "Multi-layer safety diaphragm with rup‐
ture signalling (contact)" are approved for use with flammable feed
chemicals with electrically conductive dosing heads, at back pres‐
sures of over 2 bar and only if the operator takes appropriate safety
measures.
nOnly pumps with the design "F - Physiologically safe with regard to
wetted materials" are approved for use in physiologically harmless
applications.
nOnly “H - Hygienic head” design pumps may be used for applications
in accordance with the hygienic requirements of the EHEDG
(www.ededg.org).
nThe pump may only be started up after it has been correctly installed
and started up in accordance with the technical data and specifica‐
tions contained in the operating instructions.
nObserve the general limitations with regard to viscosity limits, chem‐
ical resistance and density - see also the ProMinent Resistance List
(in the Product Catalogue or at www.prominent.com)!
nAll other uses or modifications are prohibited.

nThe pump is not intended for the metering of gaseous media and
solids.
nThe pump is not intended for the metering of explosive substances
and mixtures.
nThe pump is not intended for unprotected use outdoors.
nThe pump is only intended for industrial use.
nOnly allow trained and authorised personnel to operate the pump -
see the following table.
nYou have a responsibility to adhere to the information contained in the
operating instructions at the different phases of the unit's service life.
nYou have a responsibility to observe the information contained in the
operating instructions for the auxiliary equipment at the different
phases of their respective service lives.

Explanation of the table:
Trained, qualified personnel
A trained, qualified employee is deemed to be a person who is able to
assess the tasks assigned to him and recognise possible hazards based
on his training, knowledge and experience, as well as knowledge of perti‐
nent regulations. A trained, qualified employee must be able to perform
the tasks assigned to him/her independently with the assistance of
drawing documentation and parts lists. The assessment of a person's
technical training can also be based on several years of work in the rele‐
vant field.
Electrical technician
An electrical technician is able to complete work on electrical systems and
recognise and avoid possible dangers independently based on his tech‐
nical training and experience as well as knowledge of pertinent standards
and regulations. An electrical technician must be able to perform the tasks
assigned to him/her independently with the assistance of drawing docu‐
mentation, parts lists, terminal and circuit diagrams. The electrical techni‐
cian must be specifically trained for the working environment in which the
electrical technician is employed and be conversant with the relevant
standards and regulations.
Instructed person
An instructed person is deemed to be a person who has been instructed
and, if required, trained in the tasks assigned to him/her and possible dan‐
gers that could result from improper behaviour, as well as having been
instructed in the required protective equipment and protective measures.
