7 Operation
7.1 Use conditions
WARNING
Risk of injury due to the use of hydrogen as tracer gas
Hydrogen can be used as a tracer gas for leak detection. Depending on its concentration, in the worst
scenario, there may be a risk of explosion.
►
Never use a tracer gas with a hydrogen content greater than 5%.
►
Use hydrogenated nitrogen as a tracer gas: mix of 95% N
2
and 5% H
2
.
NOTICE
Leak detector ventilation
In cases of poor ventilation, there is a risk of deterioration of the detector’s internal components by
heating.
►
Comply with the ambient operating temperature.
►
Do not obstruct the ventilation grids.
►
Ventilation grids should be cleaned regularly.
►
Leave a free space of at least 10 cm all around the leak detector.
►
Store nothing under the detector.
NOTICE
Risk of deterioration from solid particles
The tested applications may generate solid particles.
It is recommended in this case to protect the detector inlet (inlet port).
►
Install a filter at the detector inlet (see chapter “Accessories”).
Environmental conditions: see chapter “Technical characteristics”.
7.2 Prerequisites for optimizing use
Before each commissioning, and in order to optimize the use of the leak detector, the user must ob-
serve the following points.
►
Become familiar with the safety instructions.
►
Check that all the connections are correct.
►
Do not move the product as soon as the product is switched on.
►
Make sure that the leak detector is in an environment free of tracer gas.
►
No message should be displayed.
●
No [i Next] pictogram displayed on the main screen.
●
If the pictograph is displayed, read the message and address it.
►
Perform leak detector calibration.
►
Test only clean, dry parts/installations with no trace of water, vapor, paint, detergent or rinsing
products.
►
Check that the connected part/installation is impervious to tracer gas.
7.3 Operation monitoring
During operation, the user is notified of an incident on the detector control panel.
