• 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.
6.2. OPERATIONS PERFORMED BY USER
6.2.1. BEFORE USE
VISUAL INSPECTION BEFORE USE:
• Check the combination valve for damage (incl. label and marking). If it shows signs of external
damages, remove the product from service and suitably identify its status.
Check the combination valve for contamination. If needed apply the cleaning procedure
•
according to chapter 8.
• Check that the cylinder gas pressure indicator indicates sufficient pressure. If it indicates in
the red zone, return the cylinder with combination valve back for filling.
LEAK-TIGHT AND FUNCTIONAL TEST BEFORE USE:
Set flow control head (if any) on ZERO position - ensure the flow control head engages
•
correctly.
• Slowly open shut-off valve handwheel (anticlockwise) until fully open - after approx. 1 turn (see
indication in picture chapter 5).
• By listening check for leakage (leakage would be heard as characteristic hiss of flowing gas).
• Check that there is a gas flow at each flow control head set position in both clockwise and
anticlockwise turning direction (for instance by sound or checking presence of bubbles in a
humidifier).
• Close the shut-off valve (clockwise). Do not use excessive torque (max. closing torque is 5
Nm).
• Reset flow control head to ZERO position and ensure flow control head engages correctly.
• For combination valve fitted with pressure outlet, ensure it is in working condition by
connecting and disconnecting quick-coupler probe.
6.2.2. USE OF COMBINATION VALVE
6.2.2.1. Use of combination valve flow outlet and setting of flow:
• Ensure the flow control head is in position "0".
Connect accessories to the flow outlet.
•
• Slowly open shut-off valve handwheel (anticlockwise) until fully open - after approx. 1 turn (see
indication in picture chapter 5).
Set flow head to required flow position. Ensure flow control head engages correctly.
•
Before connecting any accessory to the flow outlet make sure that the patient is not connected.
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.
Always ensure that the flow control head has been correctly set and not placed between two
settings. Flow control head placed between settings will not deliver correct flow of medical
gas.
Common variants of flow control head can have an "end stop" in between the maximum flow
position and the zero position. Do not try to apply excessive force on the flow control head
when it stops in the maximum flow position (during clockwise rotation) or in zero position
(anti-clockwise rotation).
