I have got to do an oil change on a chiller at the end of this week. I was going to do it last week but had to put it back a few days. For the life of me I can't think how I am going to get the oil from the separator. I have checked every service bulletin, every manual and training note I have but don't think there is a bleed on the separator. The filter change will be the same as the HXC and GX, the oil removal from the compressor and lines is the same, but the oil in the separator I can't think how to remove. I don't want to have to disconnect the bottom oil level switch connection if I can help it.
force external oil pump on and pump oil out from access fitting at compressor. This won't remove 100% of the oil. Stop the pump when you start to get vapor only.
Never thought of that !!
