    Between 6 or 7 lbs.

    Low pressure side 24 lbs

    High pressure side 284 lbs

    Post your email address and I will send you the service manual.

    I really have to clean my condensors to keep the pressures down and to make the system work properly. Being between the drive wheels makes them hard to get to.

    I’ll look at the engine door label tomorrow. I have heard the same about keeping the condeser clean. I’ve never had that problem even after driving the dusty roads of Alaska. I did pressure wash it when I returned. FWIW, the PO of my coach upgraded the fans on the condenser. I have no basis for comparison, but maybe the new fans move more air.

    Charles, you have a manual on servicing the CC OTR Air?

    Hey Gil, I have the service manual for the TM 31 compressor, nothing on this from CC.

    The label on mine, although a bit hard to read, says 128 oz.
