Refuelling A Vehicle - Compac CNG Service Manual

Refuelling a Vehicle

There can be up to three storage banks for CNG refuelling. During filling the dispenser
sequences through these banks from low to high as the pressure in the vehicle
cylinder increases and the flow rate drops.
Appropriate personal safety equipment should be worn whilst refuelling a vehicle.
To refuel a vehicle
▪ Press the start button or remove the nozzle from the holster to initiate a fill.
▪ The display will show 888888 and clear, at this point both the gas and

▪ Connect the refuelling nozzle to the vehicle.
