    looking for help

    hey all. im a 25 year supermarket refrigeration veteran and have been asked to help out a local engineering firm to resurect an older thermotron unit. it like most was r-13 and r-503 origanally. now it looks like r-23 and r-404 would be the gasses of choice. i have numerous questions for anyone who has input on such issues. expansion tanks,oil return,total volume of r-23 as a vapor equation for the expansion tank... ect. and if u didn't notice i am computer illiterate haha. my e-mail is sadie333z@gmail.com
