GENERAL

1.1 INFORMATION ABOUT THIS INSTRUCTIONS MANUAL

These instructions are only intended for use with gas supply panel product type:

• MTLX – gas supply panel for one cylinder

• MTLT – gas supply panel for three cylinders

Gas supply panels of this type are suitable to take gas out of gas cylinder or bundle and reduce the pressure.

With MTLT and its three gas cylinders the gas ﬂow is longer guaranteed and cylinder change is possible

without interrupting the gas ﬂow.

These gas supply panels were installed as permanently wall assembly.

These instructions enable you to operate the system safely and eciently. These instructions form an integral

part of the system and must always be kept with the system and within easy reach of sta at all times.

Prior to commencing any work, the sta must read these instructions carefully and understand the contents.

Observance of all the safety information and instructions for operation that are contained in these instructions

is essential to ensure work safety.

Local accident prevention regulations and general safety regulations governing the use of the system must

also be observed. Illustrations in these instructions serve to ensure a basic understanding of the system and

may dier from the actual version.

1.2 INFORMATION ABOUT THIS GAS SUPPLY PANEL

Gas supply panels of this type are only suitable for gases deﬁned as standard gas. The maximum working

pressure for these panels is 300 bar.

Standard gases are industrial, inert, ﬂammable and oxidizing gases and/ or their mixtures. Not allowed are the

components for corrosive and/ or toxic gases and/or their mixtures.

Single stage gas supply panels consists of valves and a pressure regulator with metal diaphragm, created

and approved as ISO7291 including oxygen shock test.

The MTLX – gas supply panel for one gas cylinder consists of one inlet pressure shut-o valve, one pres-

sure regulator with inlet and outlet pressure gauge. At the version with inert gas purging there is also outlet

pressure purge gas valve.

The MTLT – gas supply panel for three gas cylinder consists of four inlet pressure shut-o valves (three to

shut-o direct and separate at gas cylinder, one to shut-o complete inlet pressure), one pressure regulator

with inlet and outlet pressure gauge. At the version with inert gas purging there is also outlet pressure purge

gas valve.

Please do not hesitate to provide us with information and experiences gained through use; we welcome any

valuable input that will help to improve our products.

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 gas supply panel are only usable for the deﬁned standard gases and pressures observing the given

temperature range. The maximum ﬂow is 20 m3/h.

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 produce dangerous situations.

• Never use the panel with liquid ﬂuids.

2.1.1 STRUCTURAL CHANGES AT THE GAS SUPPLY PANEL

Without written approval of supplier no extensions, additions or alternations are allowed on the gas supply

panel.

Components which are not in perfect condition have to be changed immediately.

Cleaning of gas supply panel and disposal of residues

Used components 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.

7/46

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 han-

dled 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.

• 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 condition.

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 shut-o 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.

• 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.
