<p class="MsoNormal">Hi All –<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Our XL-A shut down 20 hrs into an equilibrium run because it apparently lost vacuum. It is clearly pumping some because while the reading never gets below 1000 microns we can hear inrush air when we release it. Is there any useful troubleshooting
I can do while waiting for the service engineer?<o:p></o:p></p>
