    old RRU30 oil change

    How do you guys (if you can remember that far back) change the oil in the old blue RRTI RRU30 recovery unit? There is only the 3/8 oil drain to fill through, kinda small for any funnel I have.
    Thanks

    I'd pull a vacuum on the inlet port (Ithink it was the inlet port)??? and it would pull the oil into the compressor. Try it, if it doesn't work connect your vacuum pump to the discharge port. Been too many years since I messed with one.

    Thanks, I had finally figured it out, I put the pump on the oil discharge port (stood the unit upright) and pulled the measured amount of oil in to the suction side of the unit.
