Operating instructions

This symbol indicates a situation which might
be dangerous. Ignoring this information can re-
sult in minor injury or damage to property.
+ This symbol indicates important information for
correct handling of the pressure device. Hints for
operation and particularly useful information are
provided. Ignoring this information can result in
malfunctions at the pressure device or in the sur-
rounding area. Hints for operation help you to use
all the functions of your pressure device optimally.
2.8 Organizational measures
The required personal protective equipment must be
provided by the operating authority.
All the safety devices must be checked regularly.
In case of oxygen shortage or excessive contaminant
concentration, respiratory equipment which is indepen-
dent of the surrounding atmosphere is required (VBG 1).
2.9 Protective equipment
Every time the pressure device is started up, all safety
equipment must first be correctly fitted and in working
order.
Protective devices and safety equipment must only be
removed after the pressure device or system has been
put out of operation and the pressure device has been
secured against re-starting.
When partial components are supplied the operating au-
thority must ensure that the safety equipment is fitted
correctly.
2.10 System controller
tion of safety equipment at least once annually.
2.12 Danger from electricity
Have work on electrical components, display units and
control units carried out only by a trained electrician.
Check the electrical equipment of the system regularly.
Rectify loose connections and damaged cable immedia-
tely.
The switch cabinet and the electrical units must be kept
closed. Access is restricted to
authorized personnel with key or tools.
If work must be carried out on live components, a se-
cond person must be present to switch off the main
switch if necessary.
2.13 Danger from pressure
Sections of the system and pressure lines which are to
be opened must be depressurized before starting repair
work.
Check flexible hose lines at appropriate intervals. Re-
place them even if defects relevant to safety are not
found.
External inflences such as high temperatures, heat ra-
diation, impact and similar can cause gas cylinders or
pressurized parts of the system to heat up excessively
or burst. Please take the appropriate precautionary and
safety measures.
and explosion!
Use only lubricants with oxygen approval.
With acetylene, do not use pipework or system compon-
ents made of copper! Note the particular dangers asso-
ciated with acetylene!
2.16 Emission of harmful gases and vapours
When safety equipment is open, or in case of mal-
functions, harmful gases can escape (see above). Ensu-
re sufficient ventilation or extraction.
Take special precautionary measures with dangerous
media. In particular, lead off relief valve and purge val-
ve via rigid pipework and dispose of the substances in a
safety-conscious and environmentally responsible
manner.
Never make alterations to the programme!
The controller must be operated by trained personnel
only.
2.11 Safety measures in normal operation
Before switching on the pressure device, ensure that no-
one can be put in a situation of danger due to the pressu-
re device start-up.
Check the pressure device for leaks and correct func-
2.14 Particular dangers from outward
leakage
If very hazardous, hazardous or slightly hazardous gases
are used, leaks from the pressure device can cause danger
to life and limb of the user.
Therefore, a directive according to § 20 GefStoffV, a cur-
rent EU safety data sheet according to
§ 14 GefStoffV and accident instructions with informa-
tion for the doctor must be kept at a suitable place.
Operators must be informed of the particular dangers
associated with the gas and of any personal or other
protective measures.
2.15 Information on special gas types
All parts which come into contact with oxygen must
be absolutely free of oil and grease, danger of fire
2.17 Servicing and maintenance,
rectification of malfunctions
Have prescribed setting, servicing and inspection work
carried out punctually by the manufacturer or by a spe-
cialist firm authorized by the manufacturer.
Inform operating personnel and users before servicing
and maintenance work starts.
All upstream and downstream equipment required for
controlling the pressure devices and/or the system,
such as compressed air and hydraulic systems, must be
secured against unauthorized start-up.
Before all servicing, maintenance and repair work, the
associated equipment must be switched off electrically.
The main switch must be secured against unauthorized
start-up.
Lock the main switch and remove the key.
Attach a warning sign to prevent it being switched on.
Check tightness of screwed connections which were re-
leased.
Check function of safety equipment after completion of
servicing work.
2.18 Constructional alterations to the
pressure device or the system
Do not make changes, additions or alterations to the
pressure device without written approval from the ma-
nufacturer.
Parts of the system which are not in perfect working
