Hello,

I apologize if i am posting incorrectly this is my first time. I currently work for a large semiconductor facility and we are running a line of Unisem chillers for our tools that we do not have vendor service manuals for. We are currently experiencing icing issues on our compressors and can not find the necessary instructions or service periods for changing out the refrigeration filters inside of the units. Does anyone know of a source where the manuals may be obtained outside of the vendor? Apparently obtaining them through the vendor is a non option according to my higher ups.
