If you have a suspect that inner parts of the combination valve have been contaminated, it
must be withdrawn from the service immediately.
6.1.3.2. Combination valve venting
A. VENTING OF COMBINATION VALVE THROUGH FLOW CONTROL HEAD:
Ensure the shut-off valve is closed.
•
• Set flow control head in maximal position - ensure that flow control head engages correctly.
• Wait until the combination valve is completely vented.
Set flow control head in position "0" - ensure correct position of flow control head.
•
B. VENTING OF COMBINATION VALVE THROUGH GAS PRESSURE OUTLET:
• Ensure the shut-off valve is closed.
Insert quick-coupler probe in the combination valve quick coupler (refer to appendix Nr. 2 to
•
get information about connecting / disconnecting procedure of quick coupler type on your
product).
Wait until the combination valve is completely vented.
•
• Disconnect quick coupler probe.
Venting through the combination valve quick-coupler must only be performed with appropriate
quick coupler probe to prevent combination valve damage.
6.1.3.3. Fitting the filling adaptor
• Connect the filling adaptor using max. tightening torque of 3,5 Nm.
To prevent combination valve damage, pressure inside the combination valve must be vented
according to 6.1.3.2 before fitting the filling adaptor.
Pneumatic or electric wrench can be used with some types of filling adaptors. However these
must be equipped with a torque limiting device to ensure tightening torque will not exceed
3,5 Nm.
6.1.3.4. Venting of residual gas from cylinder
A. CYLINDER VENTING THROUGH FLOW CONTROL HEAD:
• Slowly open shut-off valve handwheel (anticlockwise) until fully open - after approx. 1 turn (see
indication in picture chapter 5).
Set flow control head to maximal position - ensure that flow control head engages correctly.
•
• Wait until the cylinder has vented completely.
Close the shut-off valve (clockwise). Do not use excessive torque (max. closing torque is
•
5 Nm).
• Set flow control head in "0" position.
B. CYLINDER VENTING THROUGH GAS PRESSURE OUTLET:
• Slowly open shut-off valve handwheel (anti-clockwise) until fully open - after approx. 1 turn
(see indication in picture chapter 5).
Insert quick-coupler probe in the combination valve quick coupler (refer to appendix nr. 2 to
•
get information about connecting / disconnecting procedure of quick coupler type on your
product).
Wait until the cylinder has vented completely.
•
• Close the shut-off valve (clockwise). Do not use excessive torque (max. closing torque is
5 Nm).
Disconnect quick coupler probe.
•
Note: Venting of the cylinder by following steps A or B can be performed prior to fitting the
filling adaptor. Venting of the cylinder by following steps 'C' and 'D' requires the filling adapter
to be fitted to the combination valve first according to chapter 6.1.3.3.
C. VENTING OF THE RESIDUAL GAS FROM CYLINDER THROUGH A FILLING PORT
Ensure all lines of the filling manifold are correctly connected to the combination valve filling
•
ports
• Ensure the manifold vent valve and isolation valve is closed
