5.1
Installation position
Attention must be paid to the direction of flow.
The installation position is arbitrary.
The preferred installation position should be with the spindle horizontal.
5.2
Fitting Notice
Use suitable tools.
Clean tools before fitting
Open the packaging only directly before the mounting. Free from oil and grease for oxygen (O2)
Valves for oxygen are permanently labelled with "O2".
Take note of the HEROSE information sheet "O2 instructions".
Only install the valve if the maximum working pressure and operating conditions
of the plant correspond to the valving marking on the valve.
Remove protective caps or covers before mounting.
Check the valve for dirt and damage.
DO NOT install damaged or dirty valves.
Remove dirt and residues from the pipeline and valve in order to prevent leaks.
Avoid damaging the body end.
The sealing surfaces must remain clean and intact.
Seal the valve with suitable seals.
No sealant (sealing tape, liquid sealant) may enter the valves.
Respect the suitability for use with O2.
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.
