After connecting to the hose assembly, an ope-
rational test shall be performed. It is essential to
examine that the nozzle, hose connector and
swivel are tight under pressure and do not leak
– e.g. by external application of foaming agents.
NOTE : Pressurise system gradually while
checking for leaks.
Always put back the nozzle into the nozzle
holder.
ATTENTION: Do not drop.
Do not leave on the floor
TROUBLESHOOTING
• If the lever cannot be pulled back
Check the correct seating of the nozzle to the vehicle coupling. Make sure you push the
nozzle straight and aligned towards the receptacle. A safety feature prevents operation of the
nozzle if the connection is misaligned. If you have any doubts or questions, please contact the
station personnel.
Never force operation of the nozzle. If the connection process does not work smoothly,
disconnect and re-connect nozzle as indicated under 'Operation Instructions'.
• Leakage ( escaping gas )
A small gas release upon uncoupling is normal. If uncontrolled and / or permanent gas
release to the atmosphere occurs, immediately stop fuelling. If the leakage continues, push
emergency button of dispenser, leave area and inform station personnel.
If area is safe, check tight connection between vehicle connection and the N-CNG nozzle.
Check seals of vehicle connection and the N-CNG. If the problem persists, notify the station
personnel or the service contractor.
• If the latching does not work:
Disconnect and re-connect nozzle as indicated under 'Operation Instructions'.
If it continues to not work properly or you have any doubts or questions, please contact the
station personnel.
• If the nozzle cannot be disconnected after refuelling:
Connect nozzle once again as indicated under chapter 'Operation Instructions'. Then try to
disconnect and take off the N-CNG.
Never force operation of the nozzle. If the disconnection process does not work smoothly,
inform station personnel.
If self-service is not possible, please contact a service company specialised and certified in
CNG Service Station installations.
