outlet (ex. filling adaptor), must not influence any functions of combination valve (ex. pressure
relieve valve) and inhibit legibility of labels and marking.
There is a higher risk of damage if the combination valve is used without a guard.
6.1.2.FITTING THE COMBINATION VALVE TO A GAS CYLINDER
Observe oxygen cleanliness standards during installation!
EN
• Check combination valve and gas cylinder for visible damage (especially inlet stem thread
of the combination valve and thread of gas cylinder). If it shows signs of external damage,
remove the valve or gas cylinder from service and suitably identify its status.
• Check combination valve and gas cylinder for contamination. If needed, apply the cleaning
procedure according to chapter 8. For gas cylinder cleaning, refer to the cylinder manufac-
turer cleaning procedure.
• Check if the service due or total life time of the combination valve and the gas cylinder has
not been exceeded. See Chapter 9. If service or total life time has been exceeded, remove
GCE product from service & suitably identify its status.
• Ensure that the product inlet stem is compatible with the gas cylinder (gas/ thread type).
• Check the presence & the integrity of seals / sealing materials (PTFE tape, O-ring) on inlet
stem.
• Check that the gas cylinder pressure rating is higher than inlet pressure of the combination
valve .
• Ensure that fitting equipment does not interfere with/or damage the guard and other parts of
the combination valve or cylinder.
• Assembly combination valve on gas cylinder To tighten the combination valve in cylinder use
only the square surfaces of the combination valve body. During fitting of combination valve to
the cylinder follow torque figures specified in EN ISO 13341.
The product is only designed for use with gas specified on its marking. Never try to fit to a gas
cylinder specified for different gas type.
If you suspect that inner parts of the combination valve have been contaminated, it must be
withdrawn from the service immediately.
Do not exceed the maximum torque allowed for the cylinder. Excessive torque may damage
the combination valve thread preventing its reuse. Certain types of cylinders may require
a torque lower than specified in EN ISO 13341. Check max. allowed torque value with your
cylinder supplier.
Multiple reassembly can damage inlet stem thread.
Take care not to damage external components of combination valve for instance inlet gas
pressure indicator.
6.1.3. FILLING OPERATIONS
Observe oxygen cleanliness standards during filling.
6.1.3.1. Inspection before filling
• Check if all labels and markings are legible and undamaged.
• Remove protective cover from the filling port. Keep the caps in a safety place for reuse in
transport or storage.
• Check combination valve and filling adaptor for damage. If it shows signs of external dam-
ages, remove it from service and suitably identify its status.
• Check combination valve and filling adaptor for contamination. If needed proceed with clean-
ing procedure according to chapter 8.
• Check that the service or the total life time of the GCE product and gas cylinder has not been
exceeded. See Chapter 9. If service or life time has been exceeded, remove the product from
service & suitably identify its status.
