Will be troubleshooting flow and pressure and arranging for yet another NESLAB recirculation unit later this afternoon. Raiths ervice has been contacted and a field service person will be on site either very late tonight or first thing tomorrow morning. (Tuesday) System is off line for all users until repairs can be effected and the system re-qualified for EBL performance.
