Comment: To clarify the refrigerant flow through the system, the diagram should be updated to show that not only R-14 exists in the First Stage Separator, but also, R-508B also exists at this point.

Comment: 1. Diagram arrow for Compressor Discharge is pointing in the wrong direction. Should point to the left. 2. Diagram arrow on line above the Controller pressure receiver, to the far left should be pointing down, not up. 3. Three way valve above dump trap is drawn as a two way valve. 4. Box with two fans on the upper left of the diagram should be labelled "Condenser" to be consistent with other drawings in ILM.
