area quickly. Of course it’s essential that the air pressure gauge reading is continuously monitored to
ensure that the system pressure does not build beyond a suitable value.

As the air pressure increases, the regulator setting should be decreased to an appropriate level for the
system or component being tested. The higher the pressure setting, the more fog will be delivered, and
the quicker the test area will be  lled.

Never hook the CoolSmoke to any system or component with the regulator setting in an unknown position.
A sudden, excessive increase in pressure will result in damage to the component.
