WARNING
TOXIC OR CORROSIVE HAZARD
The sample containment system must be carefully leak checked upon installation and before initial
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.
