    Adding oil to compressor



    Been asked to work on a chiller for the first time and I'm getting a little stuck. Its a cosfi chiller with bitzer compressor.
    So far I've reclaimed gas, pressure tested with ofn and rectified a leak.

    I've now been asked to perform an oil change while the system is degassed. I've found the drain plug and drained the oil.
    Is there any way to add oil without the use of an oil pump? I'm now completely stuck.

    Can anyone please help?

    Re: Adding oil to compressor

    I usually pump it in with a hand pump but you could isolate the compressor from the system, use your vac pump to pull a slight vacuum on the compressor body and with a clean gauge line connected to the oil fill port and the other end in an oil can suck the oil in.

    I would then vacuum the compressor and then break the vacuum with ofn, it is being left for some time to get any air out that got sucked in.
    Mostly found in Oxfordshire, UK :)
