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 observe these precautions could result in personal injury or property damage.

For proper operation and safety, system leakage must be corrected, particularly before introduction 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 indicative bubbling or foaming. Leaks that are inaccessible to SNOOP application could evade detection by this method.
