PSL Spare Chiller
The original PSL chiller has been fitted out with the vortex style flow sensor.  In
turning the crystal chiller on, we found that the controller unit was faulty and did
not display the Termotek logo on start up.  The controller was replaced and the chiller
powered up okay.  We ran the chiller with the outlet connected to the inlet without any
problems.  The flow sensor calibration factor was changed to 0970 to account for the
vortex sensor.

The exercise was repeated with the diode chiller.

At the moment the chillers are in the large item access area, waiting for a convenient
time for us to roll them back to the chiller room.  The crystal chiller needs another
pigtail cable to be made.
