2. SAFETY
This section provides an overview of all the important safety aspects to ensure the protection of your sta
and the safe and trouble-free operation of the equipment. Further safety information relating to specific tasks
can be found in the sections on the individual life cycle phases.
2.1. INTENDED USE
The R200, R300 and R500 line regulator is only usable for the defined standard gases and pressures
observing the given temperature range. The nominal flow is 20 m/h (Air).
Intended use also includes compliance with all the information in these instructions and compliance with
reparation, maintenance working, type label and data sheets.
Any use other than, or above and beyond, the intended use constitutes improper use.
WARNING!
• Danger from improper use!
• Improper use of the system can lead to dangerous situations.
• Never use the line regulator with liquid fluids.
2.1.1. STRUCTURAL CHANGES AT THE LINE REGULATOR
Without written approval of supplier no extensions, additions or alternations are allowed on the line regulator.
Line regulator which are not in perfect condition have to be changed immediately.
Cleaning of line regulator and disposal of residues
Used line regulator which are ready for reparation has to be purged with an inert gas before.
Noise Generation
In some cases when specific influence quantities collaborate together, e.g. flow and pressure range can
cause noise generation or the gas itself. If this happens please contact supplier.
2.2. FUNDAMENTAL RISKS
The following section addresses the residual risks that may arise, even if the system is used properly.
Observance of the safety information included below and in other sections of these instructions is mandatory
in order to reduce the risk of injury and property damage and to avoid dangerous situations.
DANGER!
• Gases can be life threatening!
• Gases can supersede the oxygen in air. This can result in death by asphyxiation. Oxygen produces a
strongly oxidizing eect.
THEREFORE:
• Sucient ventilation is absolutely essential.
• Installation only through certified company.
• Observe ATEX directive.
ATTENTION!
• Risk of injury from environment!
There can be malfunctions on component due to condensation and/ or icing.
THEREFORE:
• Observe suitable temperatures.
• Protect component from liquids from outside
• Protect component from dust from outside
• Protect component from weather conditions
• Grounding has to be mounted properly

WARNING!
• Risk of injury from using oil and grease!
Oil and grease must never be used in gas regulating systems. Oil and grease are highly inflammatory and
can react violently to certain pressurized gases.
THEREFORE:
• Never use oil and grease
WARNING!
• Risk of injury from residual energy stored in the system!
If handled incorrectly, pressurized components can move uncontrollably and cause severe injury. If handled
incorrectly or defective, pressurized components can leak gas under high pressure and cause severe or
even fatal injuries.
BEFORE STARTING WORK WITH THESE COMPONENTS:
• Installation only through certified company.
• Always wear protective goggles when working.
• Always wear ear protection.
• Make sure the equipment is depressurized. Also make sure the residual energy is discharged.
• Always ensure that gas cannot leak unintentionally.
• Make sure that defective components that are pressurized during operation are immediately replaced by
trained sta.
WARNING!
• Danger of accident!
Due to wrong installation there can be serious or even mortal injuries.
THEREFORE:
• During installation the component should be kept safe
• Never throw the component
Pressurised components are only for intended use.
If there are mechanical damages at tubing or components the whole system has to be put in a safe condi-
tion. Aected area has to be blocked. Troubles which could influence safety, have to be eliminated through
qualified sta or supplier.
Especially with gases failure in pressure regulator could happen. Indications for defective regulator is no flow
or immediately rising outlet pressure. In this case system has to be regulating and the relevant department
for maintenance has to be informed. Never close exhaust piping.
2.3. OPERATOR’S RESPONSIBILITY
OPERATOR
The operator is the person who operates the system for commercial or business purposes or who provides
the system for use/application by a third party, and who bears legal product responsibility for protecting the
user, sta or third parties during operation.
OPERATOR’S DUTIES
The system is used for commercial purposes. The operator of the system is therefore subject to legal work
safety obligations.
Compliance with the safety, accident prevention and environmental protection regulations that apply for the
use of the system is mandatory, in addition to the safety information in these instructions.
THE FOLLOWING APPLIES IN PARTICULAR:
• The operator must be aware of the applicable work safety regulations and must perform a risk assessment
to identify risks that may occur as a result of the specific working conditions at the site where the system
is operated. The operator must use this assessment as the basis for compiling instructions for operating
the system.
• During the entire period in which the system is operated, the operator must ensure that these operating
instructions comply with the latest regulations, and must update the instructions if necessary.
• The operator must assign clear and specific responsibility for installation, operation, troubleshooting,
maintenance and cleaning.

9/44
EN
• The operator must ensure that all members of sta who work with the system have read and understood
these instructions. The operator must also ensure that these members of sta are trained at regular inter-
vals and are aware of the risks.
• The operator must provide the sta with the requisite protective equipment and bindingly obligate the
sta to wear the necessary protective equipment.
In addition, the operator is responsible for ensuring full technical reliability of the system at all times.
AS SUCH, THE FOLLOWING APPLIES:
• The operator must ensure compliance with the maintenance intervals specified in these instructions.
• The operator must ensure that all safety equipment is regularly inspected for functional reliability and
completeness.
