Before to release the medical gas primary package for patient use, perform functional and
•
leak-tight checks Refer to appendix nr 3 "Post filling checks".
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.
A SPECIAL ATTENTION SHOULD BE PAID TO THE FOLLOWING ITEMS:
EN
Pressure indicator functionality,
•
Check if on combination control knob "shut-off valve & flow selector" there is a gas flow at
•
each setting (for instance, by sound or special leak detector),
Integrity of product label, gas label, anti-tamper label (depending on the type), flow marks on
•
flow control head,
Presence of protective caps & plugs.
•
Do not use leak detection fluids containing ammonia or other substances which can promote
stress corrosion cracking in brass materials or can affect other materials.
For the oxygen equipment use only leak detection fluids approved for use with oxygen sys-
tems.
Contact GCE if further information is needed on approved leak fluids for your product.
After completion of the functional and leak-tight checks, refit the filling port protection cap as
•
soon as possible. Before refitting the caps ensure that they are clean. Use only genuine GCE
caps. If required, check that the anti-tamper label is in position.
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.
•
Perform combination valve venting - follow Chapter 6.1.3.2.
•
Remove filling port protective cover.
•
Ensure the combination control knob "shut-off valve & flow selector 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.
•
Open slowly the combination shut-off valve by turning slowly the combination control
•
knob"shut-off valve & flow selector" in anticlockwise direction to ON position.
Wait until the whole package for medical gas is completely vented.
•
Turn off at the shut-off valve by turning the combination control knob "shut-off valve & flow
•
selector" in a clockwise direction to OFF position. Do not use excessive force (Maximum
recommended closing torque is 3 Nm).
Remove the combination valve from the cylinder using the square surfaces of the combina-
•
tion valve body.
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.
Perform cylinder venting in well-ventilated areas to avoid oxygen saturation of ambient at-
mosphere, which could result in an increased danger of fire.
