5.1 Installation position
With regard to the installation position, pay attention to the arrow showing the flow direction. Installation of
the valve in the vertical position. The outlet “C” points vertically upwards.
5.2 Notices regarding the mounting
 Use suitable tools.
 Open-ended spanners

Torque wrench
 Clean tools before the installation
 Open the packaging only directly before the mounting. Freedom from oil and grease for oxygen
(O
2
)
Valves for oxygen are permanently marked with “O
2
”.

Only install the valve if the maximum operating pressure and operating conditions correspond to
the marking on the valve.
 Remove protective caps or covers before mounting.
 Inspect the valve for dirt and damage. DO NOT install a damaged or dirty valve.
 Remove any dirt and residues from the pipeline and valve in order to prevent leaks.
 Avoid damaging the connections.
The sealing surfaces must remain clean and intact.

Seal the valve with suitable seals.
No sealant (sealing tape, liquid sealing tape) may enter the valve.
Respect the suitability for use with O
2
.

Connect pipelines in a force-free and torque-free manner.
Stress-free mounting.
 In order to ensure trouble-free operation, no impermissible static, thermal or dynamic stresses
may be transmitted to the valve. Observe reaction forces.
 Temperature-dependent changes in length in the pipework system must be compensated with
expansion joints.
 The valve is supported by the pipework system.
 The valve must be protected against dirt and damage during construction work.
 Check the leak-tightness.

6 Operation
In the delivery state the combined pressure regulator is preset to an operating pressure setpoint (see
chapters 6.1 and 6.2). At the customer's request the combined pressure regulator will be set to an
operating pressure setpoint specified by the customer.
 The set screw of the combined pressure regulator must be adjusted in order to set or correct an
operating pressure setpoint:

To set the operating pressure setpoint, loosen the locknut and adjust the set screw accordingly.
 Clockwise rotation
Operating pressure setpoint is raised
