Comment wbmetal SNF 2012-06-23 07:56:29: Needs new chemicals

Chemicals drained for scrubber exhaust maintenance.  Make sure the PRS1000 and PRX127 baths are dry before adding new chemical.  Alternatively, rinse with a little chemical and drain several times before filling (trace water will make these chemicals strongly basic.)
