2.6 Particular danger from leakage
When using very hazardous, hazardous or slightly hazardous gases, danger to the operator and others can occur should a
malfunction or leak develop. Malfunctions of the pressure equipment or operation of relief valves and safeties can result in
the release of the hazardous gases into the work environment. When using hazardous gases take particular safety precau-
tions, including sufficient ventilation or evacuation. Securely Pipe away the exits of pressure relief and purge valves. Any
leaked materials are to be disposed of safely, in accordance with local regulations, and an environmentally friendly manner.
The operators are to be informed of the particular dangers of the gas they are using and of personal and other protection
measures necessary for the safe operation of pressure equipment.
2.7 Information on special types of gas
All parts that come into contact with oxygen must be completely free of oil, grease and particular matter, to avoid danger of
ignition and/or explosion! Where instructed to use a lubricant only use one with approval for oxygen service. When working
with acetylene, do not use tubing or other parts made of copper! Know and pay attention to the particular dangers of these
two and other reactive gases.
2.8 Design changes on the pressure control device
Without written permission from the manufacturer, no changes, extensions or redesign on the pressure control device or the
equipment are to be carried out.
2.9 Cleaning the gas device and disposal of the residue
Do not contaminate the equipment with oily rags or grease. Do not clean with solvents.
3. Storage, transport.
All pressure equipment must be clean and stored in a dust free, dry
and well-sealed environment. Do not use cleaning agents containing
solvents! Before returning pressure equipment to the manufacturer
it is absolutely necessary that all components be purged with inert
gas, if they have been in contact with corrosive or toxic gases.
4. Technical data.
4.1 Data sheets
All technical data can be seen on the product specific data sheets for
BASELINE®products. These are valid when used with the general op-
erating instructions. Specifically, the data sheets contain the maximum
intended inlet pressure, the working outlet range of the pressure device,
the external dimensions, the leak integrity or tightness, and the permis-
sible operating temperature range.
4.2 Pressure regulator series C106, C106X and R104
There are four R104 or six C106/C106X inlet and outlet ports with NPT
1/4" internal threads. Please always pay attention to the information
contained in the “Connections” and “Start-up” sections for all products.
4.3 Cylinder regulators C106/1, C106X/1 and C106/2, 106X/2
Cylinder regulators are designed to be connected directly to gas cylinders
to reduce cylinder pressure to a lower outlet pressure. The cylinder con-
nections have different threads depending on the type of gas used. Do
not use adapters or change cylinder connections.
4.4 Outlet valves
Cylinder regulators can be purchased with a type A multiple turn
Diaphragm positive shutoff valve, type B multiple turn needle valve,
or without an outlet valve. If a valve is installed, it is closed by turning
the knob in the anticlockwise direction and opened by turning it in the
clockwise direction.

5. Marking.
The nameplate lists the model number, Inlet fitting number and serial
number of the pressure equipment as well as the manufacturers name.
Caution
Only use equipment that corresponds with the type of gas and operating pressures for which it was intended. The maximum
intended inlet pressure is listed on the pressure equipment. Failure to observe the intended use can result in the danger of
injury, the danger to life, the danger of equipment failure, or fittings being damaged.
6. Connection.
Cylinder regulators
Danger
Thread on cylinder valve and swivel nut must
not show signs of damage, dirt, grease, oil,
foreign matter or metal shavings.
Warning
Only use new gaskets. Gaskets must not be
deformed, nor show traces of dirt or metal
shavings.
Caution
Before connecting, check whether the equip-
ment to be used is suitable for the planned
application (type of gas, pressure, etc.)
Warning
Do not overly tighten the mounting fitting, as
the thread and the gasket could be damaged.
This can result in leakage, uncontrolled release
of gas, or loss of the entire cylinder or gas sup-
ply contents.
Connecting to gas cylinder
1. Screw the swivel nut onto the valve connection on the cylinder by
hand first. Pay attention the right-handed and left-handed threads!
Align the pressure regulator. When mounting do not tilt!
2. Tighten the swivel nut with a suitable fork spanner.
Preparation
Only use regulators with cylinder connections that correspond to the type
of gas and the valid national standards for cylinder connections.
Connecting the outlet tubes
Tubes are usually connected with compression fittings. Assembly is car-
ried out by completely inserting the tube into the compression fitting.
Then screw on the swivel nut by hand and tighten with a fork spanner (1
1/4 turn). Please pay attention to information provided by manufacturer
as well as the suitability of the materials for certain gases and pressure
ranges.
Caution
Do not use a spanner extension as otherwise
the gasket and the thread could be damaged.
This can lead to leakage and uncontrolled re-
lease of the gas supply (complete loss of gas!).

7. Start-up.
Danger
Before starting operation, check whether the pressure device to be used is suitable for
the planned application purpose (type of gas, pressure, material, etc.)
Warning
Before switching on the pressure device ensure that no one can be endangered by
starting operation of the pressure device.
Preparation
Ensure that all fittings and connections are tightly connected. Turn the hand-wheel of the regulator in an anti-
clockwise direction until the end stop - this means that the gas flow is now stopped. Close all valves.
Process gas extraction
Slowly open the cylinder valve (shut-off valve on the pressurized gas container). Watch the inlet pressure
gauge. Adjust the required outlet pressure by turning the regulator hand-wheel clockwise. Adjust the required
flow on the regulating valve (if applicable).
8. Cylinder change.
Danger
When changing the cylinder used with toxic, corrosive, or hazardous gases, the appro-
priate protection measures are to be taken to protect personnel (breathing apparatus,
eye protection and protective clothing as appropriate or required). Maximum permis-
sible values of the concentration at the place of work must not be exceeded! Purge,
vent, and or dispose of the residual gas contents of all toxic, corrosive, and hazardous
gases in a safe and environmentally appropriate manner in accordance with local
regulations.
Preparation
Tightly close the cylinder valve (on the pressurized gas container). Close the inlet valve on the regulator if so
equipped. Completely empty the regulator. The pointers of the inlet pressure and outlet pressure gauges should
indicate no internal pressure. Turn the hand-wheel of the regulator anticlockwise until the end stop (flow
closed). Close the outlet valve.
Removal from cylinder
Using a suitable fork spanner, loosen the swivel nut from the cylinder valve connection. Pay attention that
some connections are right-hand or left-hand threads. Support the regulator during removal. If escaping gas is
noticed, reconnect the swivel nut and repeat the Preparation instructions again, making sure that the cylinder
valve is closed.

9. Shutting down operations.
9.1 Cylinder regulator
For short stops in extraction of gas it is sufficient to close the shut-off valve on the regulator. In the case of longer stops, the regulator has
to have the pressure released by turning the hand-wheel anti-clockwise. For safety reasons close the cylinder valve.
Caution
When dismantling as a general rule note: release pressure from regulator and tubing by venting the gas in a
safe manner, the pointers of the inlet and outlet pressure gauges must indicate no internal pressure.
10. Maintenance and breakdowns.
10.1 Maintenance
The pressure control device should be examined regularly to make sure
it is working correctly and to check for leaks. Prior to carrying out main-
tenance and service work, inform the operating personnel and the users.
For all service and maintenance work, shutoff and secure all power to
associated operating equipment and secure the main switch to prevent it
from being turned back on. Check fittings, which have come undone for
correct positioning. After completing maintenance work, make sure that
all safety devices and installations are functional.
Danger
For safety reasons, repairs and or maintenance
work to the BASELINE®pressure equipment,
should only be carried out by BOC service compa-
nies or their authorized service personnel.
10.2 Malfunctions
By experience these regulators have a high level of reliabil-
ity. Should any of the following breakdowns occur despite
this, exchange the regulator and have the defective equip-
ment repaired:
– Gas release at the outlet of the regulator when the hand-
wheel is completely closed.
– Display of increasing pressure on the outlet pressure gauge
when the valve is closed or no gas is flowing.
– Gas release at the regulator cover.
– Gas release at a gasket.
– Too high pressure drop with normal flow.
– Gas release at the pressure relief valve.
– Gas release at the pressure gauge.
– Pointer of a pressure gauge does not return to „0“.
– Faulty pressure display.
11. Return of pressure equipment.
Danger
Pressure equipment can only be returned with
prior authorization. It must be completely de-
pressurized, drained and purged with an inert
gas. The packaging must be sealed gas-tight
to prevent contamination or exposure during
transport.
Danger
Pay attention to local rules and legislation with regards to
transport and storage of hazardous goods and materials.
