H2 PSL installation

Holes were drilled in the enclosure roof for bolting the air conditioner units. 1-1/4" PVC pipe was set inside the holes and caulked into place. Outside the LVEA, the compressers were set into place. On Monday the air conditioner units will be installed in the enclosure.

Dust counts were elevated later in the day, with counts above 5000 at 0.5 micron, but the HAM7/8 surveying work was near the dust monitor, so the increase in counts may have been due to people standing nearby.
