I can't believe its been over a year and a half since I brought home 3 CAs and 3 FEAs from Travis's and still haven't played with a Ca much. I did run them all and found the one with the rebuild tag worked good, one is stalled and will not start and one had a bad float seat.
I have been planning for a long time to do some experimenting with the soup can that has a bad float seat. So to that end I made it go AWOL from the rack in my storage bin and crammed it into my overloaded garage.
First order business was recovering the methyl formate. I planed to force the MF into a recovery tank by heating the unit while cooling the tank. The tank, hoses and unit were in a vacuum still as all this was done,such is the nature of the methyl formate. To be sure the charging adapter and gauge set were leak free I first puled an vacuum on them to be sure they were not leaking. They held 700 microns for over 1/2 hour so I called it good. By the way I use o rings in the joints of the charging adapter. They work real good and are easy to find a replacement for. Just have to be sure they are tight.
Here it is wrapped up with a heater blowing under there.
Ice machine is off this time of year so mother nature had to provide the ice to cool the tank. Here I have a whopping 5.9 oz out so far. Altogether It took about 5-6 hours to boil all the MF out of the unit. Had to leave once to check a furnace and start over so not sure just how long. In the end the before and after weights of the tank say I got all most all of it. 2 lbs 11 oz heavier.
