    changing oil on a carrier screw chiller

    Can anyone tell me a procedure for draining the POE oil out of a carrier m/n 30hxc271nz-640ka chiller ? I have the refrigerant charge ( 134A ) isolated in the evap bundle. I have tried to pressurize the condenser bundle with nitrogen and drain the oil from a fitting on the oil pump suction line. I have only managed to remove about a gallon of oil. The spec says it holds 5 gallons. Any suggestions would be appreciated.

    Why are you changing the oil. It is a mess to change all of the oil charge. This is not a cummins that you change at 5000 miles.

    It tested slightly high for moisture content. The testing facility recommended oil replacement.

    I am looking for any info on removing the oil from the circuit, not necessarily criticism from diesel mechanics.

    Why don't you start with the filter driers?

    You need to apply for pro membership.

    This prevents us from helping a non-tech do our job, this also helps prevent someone who will pop in, ask a question and get repair help, then never return the favor.

    If you are a tech, there are plenty of factory instructions on how to change the oil in different Carrier screws.

    The truth is if you are asking this question you really ought to have help on site. You can cause a whole lot of damage while just changing oil on a chiller.

    Call your local Carrier dealer, with the model and serial of the machine, they can get you the info you are looking for.

    If they can't help you, PM me the info and I will have it faxed over to your hall.
