LOTO on Kobelco Compressor

(Heath E., Gerardo M.)
Service tech Heath was on-site to diagnose/repair the leak on the Kobelco compressor, unfortunately to be able to diagnose the system a couple of windows were lifted, the gaskets for such "windows" can't be reused and Heath did not have gaskets with him.  Now, the vendor is trying to secure a "kit" to do instead an annual service on the unit, meanwhile the compressor is LOTO, and will be down until repairs are completed, hopefully soon.

While the diagnosis was done, the compressor was powered on and ran for sometime this morning.

The compressor ran for 7 minutes, starting at 17:12 UTC and ending at 17:19 UTC, Drying tower was isolated from the compressor.
