4.3 Manually screw the regulator onto the cylinder valve (1). Tighten connection
gas-tight by using an appropriate spanner. Do not use any extension to the
spanner to increase momentum! In case of flammable and toxic gases attach a
relief line to the relief valve (4) and ensure a safety gas discharge. For cylinder
regulators with external purge gas connect the purge gas line.
4.4 Carry out the connections between the cylinder pressure regulator and the point
of use. Never allow cylinder pressure regulator to regulate into the open
atmosphere.
Wind PTFE tape (Art. No. 0321422) clockwise around NPT-screwed
connections (5 to 10 turns). Check all connections for leaks.
4.5 Release the pressure regulator spring with the hand knob (6) - open the cylinder
valve (1) (High pressure gauge 3 indicates the cylinder pressure) - Adjust the
required outlet pressure with hand knob (6). Correct the pressure setting in case
of a decrease of pressure.

5. Operation and maintenance
5.1 Before commisioning check on the nameplate if the regulator is suitable for the
gas type. The designated gas type has to be marked on the nameplate using gas
type stickers or by writing the gas type into the space provided on the
nameplate.

2. Safety instructions
- Guidelines for laboratories (Zh 1/119)
- Technical regulation (liquified pet. gas)
In case of flammable gases, thedischarge of the gas from the relief valve (4)
must be ensured. For this use connector 1/8-NPT/6mm pipe (art. no. 0291677).
No adapters must be used between the gas cylinder valve and the pressure
regulator.
2.1
All items of information marked with are valid as special safety instructions.
2.2
These pressure regulators adhere to state-of-the-art technology and
to the demands of the exsiting standards and regulations.
2.3
Changes or modifications are not allowed to be made to the pressure
regulator without the prior consent of the manufacturer.
2.4
The result of improper handling and improper use as intended can involve
risks for the user and other persons as well as damage to the device.
2.5
The equipment must be operated by suitable trained personnel only.
2.6
Regulations to be adhered to:
- BGV A1 (VBG 1), “General specifications”
- BGV B6 (VBG 61), “Gases"
- BGV B7 (VBG 62), “Oxygen”
Special attention has to be paid to the country specific laws, regulations
and procedures concerning the use of this type of equipment.
2.7
Use only for gas types the pressure regulator is labelled for (see item 3).
2.8
2.9
Do not use at temperatures below -30°C or above +60°C.
