    The new CHHN060 shipped with a crankcase heater. The old compressor did not have one.

    The original wiring diagram does not show a heater on the original diagrams.

    Comfort site does not show a service bulletin.

    No way to wire the 110v heater unless we rewire.

    There is a hole in the casing to accept a heater on the new compressor and the old defective original.

    Any knowledge out there on this or service bulletin?

    The RTWA doesn't have a crankcase heater... It is water cooled. (If memory serves me correctly).

    RTAA-w-2 Wiring Diagram??

    i also need the wiring diagram RTAA-w-2 for a RTAA185. I am searching online cant find anything. I am trying to figure out if the under/over voltage transformer is suppose to have a fuse protecting it and if so what size was originally there? The drawing 2307-3327B shows fuses for "1T2" for the RTAA 70-125 models but cant find a diagram for the 185 ton model?? Who ever has a copy please email me or copy and paste a link?
