2. Instruction

2-3. Testing

Each nozzle & swivel should be tested after installing and replacing.
Necessary facilities
Approved metal test container (please obey the local laws and regulations)

Ground wire

Insulation resistance tester

Stopwatch.

Deal with static electricity before flow test.
Confirm that the electrical resistance between the nozzle tip and dispenser main ground terminal is less

than 1MΩ. (Note: electrical resistance between of any point of spout to coupling should be ≤ 0.1MΩ)
Ground the approved metal test container and the nozzle with ground wires.

Discharge static electricity in the human body.

Flow test
1. Leak confirmation
Start pump, and check for leaks between the nozzle & swivel and hose connections.

2. Flow rate test
Measure the flow rate of the nozzle first latch position.

Ensure the maximum flow rate is below the maximum flow rate of the dispenser.

3. Automatic shut off test
Start flow into approved metal test container; place nozzle in first latch position.

Immerse the sensor on nozzle spout tip below the level of liquid.

Nozzle must shut off immediately.

Repeat procedure for nozzle low latch position.

Repeat the procedure above three times at nozzle all latch position.

4. Pressure-controlled safety shut-off test
Preset refuelling quantity (more than 5L) to dispenser.

Start flow into approved metal test container in the nozzle full-open position.

Confirm that flow is stopped with quantity of preset refuelling.

Stop pump.

Grasp nozzle lever to fully opening position; restart pump.

Confirm that there shall be no fuel flow.

Repeat the procedure above three times.

1. Please read safety instructions "HINTS AND TIPS FOR SAFE USE" completely before installing and
replacing nozzles.
2. Ground the approved metal test container and the nozzle surely.
Discharge the static electricity in the human body.
Static electricity may ignite gasoline vapours.
