pressure, ambient temperature, size and material of the cylinder, type of gas, speed
and duration of venting)
Venting through the combination valve quick-coupler must only be performed
with appropriate quick coupler probe with inner hole of 1 mm to limit flow prevent
combination valve damage.
6.1.3.5 Cylinder filling
•
Ensure the shut-off valve on combination valve is fully open.
•
Proceed with filling the gas cylinder.
•
Close shut-off valve after filling. Do not use excessive torque (max. closing torque is 5 Nm).
•
Vent the filling connections (including high pressure filling hose).
•
Disconnect filling adaptor.
•
Before releasing the gas package for patient use, perform functional and leak-tight checks
(refer to appendix Nr. 3 "Post filling checks").
•
After completion of tests according to appendix Nr. 3, return the filling port protective cover.
Use only original GCE protective cover.
Pressure in the filling connections during disconnection of the filling adaptor or open
shut-off valve of combination valve may cause personnel injury or damage to the
combination valve or filling adaptor.
Make sure that during filling the surface temperature of combination valve and cylinder
does not exceed the allowed maximal limits. Temperature increase is affected by size
and material of cylinder, type of gas, duration of filling and filling pressure.
6.1.4 REMOVAL OF COMBINATION VALVE FROM CYLINDER
•
Observe oxygen cleanliness standards during removal.
•
Perform cylinder venting – follow Chapter 6.1.3.4, step A or B.
•
Remove filling port protective cover. Some types of covers are permanently connected to
the combination valve or guard. This is to prevent its loss and such connection should not
be broken.
•
Ensure the combination valve shut-off valve is closed.
•
Ensure the inlet pressure indicator indicates an empty cylinder. If not, the combination valve
is broken. Do not use it and send it for repair according to chapter 9.
•
Connect filling adaptor.
•
Slowly open shut-off valve handwheel (anti-clockwise) until fully open - after approx. 1 turn
(see indication in picture chapter 5).
•
Wait until the whole package for medical gas is completely vented.
•
Close shut-off valve (clockwise). Do not use excessive force (max. closing torque is 5 Nm).
•
Remove the combination valve from the cylinder using the square surfaces of the
combination valve body. Size of square surface is 26 mm.
•
Place filling port protective cover back on the combination valve with the gas cylinder pack
and store in a way to prevent damage during storage and handling.
Use only genuine GCE filling adaptors. Other filling adaptors may damage the non-
return valve in the filling port and impact the safety of the product.
Sudden opening could result in a danger of fire or explosion arising from oxygen
pressure shocks. Insufficient opening of the shut-off valve could reduce actual flow
delivered.
