Re: Mcquay Chiller problem
The ALS chiller has probably got frame 2 Hall Screw compressors fitted, the oil charge is calculated upon the amount of refrigerant charge and is pumped into the refrigerant circuit while running. the No Liquid Run is caused due to either a faulty opto sensor which is located in the compressor body at low level or lack of refrigerant liquid injection into the machine, is there a solenoid in the liquid injection line?

Yes, there is a solenoid ion the liquid injection which tested ok, put it down to lack of refrigerant due to a restricted drier.
Going back soon with new core, will let you know.
