Use
4.1
Complying the use with the aim
The spray gun can be used with all the ASM xxx leak detectors.
The spray gun is aimed at getting connected to the bottle which contains the tracer
gas required to the leak control.
It allows spraying part or installation to be tested with tracer gas in order to locate a
possible leak.
Any other use is inappropriate to the product’s aim.
4.2
Checking before the use
Î
Connect the spray gun to the gas bottle.
Î
Drop the spray gun’s nozzle (2 cm) in a water container.
Î
Handle the spray gun: bubbles from the tracer gas must appear in the water.
4.3
Process
Î
Slowly sweep the part that is to be checked using the gun spraying tracer gas (start at
the top of the part then go down): check on your detector if a leak is detected and mea-
sured.
