Hi all, new here and finding this site very interesting, heres my issue. Called to a Mcquay ALS chiller last week, not able to investigate as customer wanting get home, so retrieved fault code after a quick test run of about 1 min before faulting, noisey comp, sounds like lubrication issue, a return visit booked in. No manual on site and Mcquay not that helpful, i could do with obtaining manual etc as much info as possible or even help on the fault.
The circuit 2 show "NO LIQUID RUN" ?
what does this mean, what checks can be carried out to determine the problem, any help woul be much appreciated.
Cheers, keep up the good work.
