Late entry:
On Tuesday, the Kobelco was started to use the dry air to purge one of the turbo headers located in the LVEA.  After starting the booster pump, a very small leak was found while performing the pre-starting inspection of the compressor, two drops of coolant were found on the catch pan inside the enclosure, the leak was traced to the gasket on the joint for the flanges of the "intercooler shell" and the "inlet adapter" (see on "Diagram" items 1, 3, and 4) unfortunately no torque specifications for the bolts holding both pieces together were found, so we did not wrench on it.  A vendor was contacted and they are send a technician to diagnose/fix the leak on Monday.
The Kobelco ran for about 2.5 hours, the leak was monitored during such time, no noticeable increase on the leak was noted, but remained present.  The drying skid was turned on and the RH was measured, -41.1 degrees C for one tower, the other tower read -42.3 degrees C, RH was monitored during the period of operation and no changes were noted.
