    Unless they are doing that to help reduce cavitation....

    I'd have to read something about that fan to really know, but yes, CW in the pic WILL pull from the armature toward the shaft end.

    i'm confused............... if it spins ccw, and the fan is supposed to direct refrigerant into the motor, installation is correct.
    they used vapor to cool the stator? usually they inject liqwid

    From looking at the parts list on page two of the pdf, it looks like one fan goes on the far end for CW, and one goes on the near end for CCW.

    Which way does your shaft turn? CCW as shown in your picture?
