When installing a GENIE 750 or GENIE 755 sampling probe, it is essential to check that there are no leaks in the cable gland. The stuffing box, located at the top of the rod body, ensures that the probe is watertight.

\n

Using a leak detector, test the connections at the following points: Sample outlet\" side at top of probe valve still closed, Process side probe gland and any other connections made during installation... If a leak is detected on the probe gland, use a 1-3/16\" open-end wrench to tighten the gland slightly. Be careful not to overtighten, as overtightening can damage the gland. The amount of torque required to seal the gland varies with process conditions and sealing material. Harder seals, such as HNBR seals resistant to rapid gas decompression (like James Walker seals), require a higher torque value than standard seals.

\n

In this video, you'll see how to check for leaks and what to do in the event of a leak.

\n

\n

You should also be aware that it may be necessary to retighten the gland periodically when process conditions change, or because the seal wears out during insertion and removal.

\n

If a layer of ice has formed on the cable gland, it's probably not completely watertight. Nothing serious, just retighten the gland.
