OPERATING INSTRUCTION FOR CYLINDER PRESSURE REGULATORS
CORRESPONDING TO EN ISO 2503
These instruction are intended to ensure the safe operation of pressure control regulators inconformity with the
effective regulations. Careful attention to these instructions will help to avoid risks and loss of production as well as
enhance reliability and durability of pressure control equipment.
THESE INSTRUCTIONS MUST BE KEPT PERMANENTLY AT HAND IN YOUR WORKSHOP.
For Safety Instructions also see paragraph 2; in case of doubt do consult the manufacturer.
OPERATION
1.1. Use in conformity with effective regulations:
Pressure control regulators are intended to be used with compressed gases or with under pressure dissolved gases in
cylinders having a filling pressure of max. 300 bar,also for liquid gases, and to reduce the respective cylinder pressure
as well as to ensure a constant working pressure. Pressure control regulators may only be used for those gases that
are mentioned in the markings of the valve (see Markings, paragraph 3).
1.2. Use contrary to effective regulations
• pressure control regulators must not be for gases in state of liquidity
• pressure control regulators must not be operated under ambient temperatures of under -20°C or above +60°C.
• pressure control regulators must not be for corrosive gases, such as ethylamin, dimethylamin, ammonia etc.
SAFETY INSTRUCTIONS
All indications showing this exclamation mark are important safety instructions.
2.1. Under no circumstances must the Cylinder Pressure Regulator be modified or tampered with without the written
consent of the manufacturer.
2.2.
Intermediary connections between the Cylinder valve and the Cylinder Pressure Regulator are strictly prohibited.
2.3. Regulations to be adhered to: EN ISO 2503 Cylinder Pressure Regulator.
2.4. Incorrect use may endanger the operator and other personnel, damage to the Cylinder Pressure Regulator and
Installation may also result in fire and / or explosion.
DESIGNATION CORRESPONDING TO EN ISO 2503 (SEE FIG. 1)
MARKING
Gas Type: A=Acetylene; O=Oxygen; P=LPG; N=CO2/Nitrogen/Inert Gas; H=Hydrogen; D=Air; M = Methane/Natural
gas; Y = MPS
P1=Maximum inlet pressure; P2=Maximum outlet pressure/flow; Class = EN ISO2503 class number
OPERATING INSTRUCTIONS
4.1. Keep hands and tools clean, oil and grease can cause an explosion on contact with oxygen.
4.2.
The operator should be fully familiar with these operating instructions prior to the use of this equipment, all
instructions should be adhered to when in use.
4.3.
Check that the Cylinder Pressure Regulator is suitable for the gas to be used. (See markings paragraph 3).
4.4. Check that the Cylinder valve connection is clean and undamaged; if not, you must not connect Cylinder Pressure
Regulator.
4.5.
Before connecting the Cylinder Pressure Regulator, the Cylinder valve should be swiftly opened and closed to
dislodge water or foreign matter from the Valve/Regulator inlet seating. Do not stand in front of the cylinder valve
outlet. Do not hold your hand in front of the cylinder valve outlet.
4.6.
Connect the pressure control regulator gas tight by means of the sleeve nut respectively the bracket (2) to the
cylinder valve (1). The regulating screw (5) must show downward.
4.7.
Connect hose the connection at the outlet stud (7) and to the downstream equipment. Use hoses corresponding
ISO 3821 (EN 559) and hose connections corresponding to EN 560; secure by appropriate hose clamps.
