Hello HVAC Tech's
I have been out of the field for a few years and in the next couple of weeks I might have the pleasure of changing out a large screw compressor on a Mcquay chiller. I think the compressor is around 75 hp. 480/3 R-22 grounded out. besides the normal clean up and suction line filters, Does anyone have any tips or know of anything special I will need to know or do for this change out. I have never done a screw compressor but have done 65hp trane compressors.
I thank you for any info you can give me.
