2-4 LEAK TEST
WARNING
TOXIC OR CORROSIVE HAZARD
The sample containment system must be
carefully leak checked upon installation
and before initial start-up, during routine
maintenance and any time the integrity of
the sample containment system is broken,
to ensure the system is in leak proof con-
dition.
Internal leaks resulting from failure to ob-
serve these precautions could result in
personal injury or property damage.
For proper operation and safety, system leak-
age must be corrected, particularly before in-
troduction of toxic or corrosive samples and/or
application of electrical power.
To check system for leaks, liberally cover all
fittings, seals, and other possible sources of
leakage with suitable leak test liquid such as
SNOOP (P/N 837801). Check for leak indica-
tive bubbling or foaming. Leaks that are inac-
cessible to SNOOP application could evade
detection by this method.
