Operating Instructions Pressure Gauges
Selection Criteria, Measuring Arrangements, Installation and Operation Manual
Qualified personnel:
• The personnel that is charged for the installation, op-
eration and maintenance of the instrument must hold
a relevant qualification. This can be based on training
or relevant tuition. The personnel must be aware of
this manual and have access to it at all times.
• The electrical connection shall be carried out by a
fully qualified electrician only.
General safety instructions:
• In all work, the existing national regulations for ac-
cident prevention and safety at the workplace must
be complied with. Any internal regulations of the op-
erator must also be complied with, even if these are
not mentioned in this manual.
• Use the instrument in its perfect technical condition
only. Damaged or defective instruments need to be
checked immediately and replaced if necessary.
• Only use appropriate tools for mounting, connect-
ing and dismounting the device.
• Nameplates or other information on the device shall
neither be removed nor obliterated, since otherwise
any warranty and manufacturer responsibility expires.
• In order to ensure measurement accuracy and du-
rability of the instrument and to avoid damage, the
limit values indicated in the technical data have to
be observed.
• In case of visible damage or malfunctions, the in-
strument must be put out of operation immediately.
• Excessive heat (e.g. during or after external fire),
especially on soldered joints, may cause leakage of
the medium, which in turn can cause serious haz-
ards. After an external fire, all instruments have to
be checked before recommissioning the system
and have to be replaced if necessary.
Special safety instructions:
Warnings, which are specifically relevant to individual
operating procedures or activities, are to be found at
the beginning of the relevant sections of this operating
instruction.
