Last Sunday I brought home from Travis's this rather nice D-35-16. Love the evaps on this one. It runs great but didn't cool much at all.  It still had some so2 inside and after running it and turning it upside down I decided this is another classic case of a restricted float.  After recovering the remaining so2 though a line tap that had been added I had to remove the float screw. It was very buggered up but I managed to get it out and replaced it with one from the stalled DR2. They are not exactly the same as can be seen in pic but did interchange and work.  The plan is for a 134A conversion and it looked like there was just enough room to get a suction line restrictor in.  With this section of suction line out I was not able to blow nitrogen through the float even though the unit was upside down to be sure float was open. I then blew nitrogen backwards though the evaps and float and it went through without much problem. I was then able to blow though in both directions.  Next I installed a 7.5" long "Pig Tail" restrictor. Should not even see it when looking from the front.  Then I carefully lifted the capacitor transformer out of the way and cut the liquid line just before the float.  Tucked in the same filter drier I used on Travis's DR3   Next it got an all night vacuum pulled on it. |

I think you found your second calling. Nice work and nice pictures. The pictures don't make it look heavy at all.

I think you found your second calling. Nice work and nice pictures. The pictures don't make it look heavy at all. Its much easier to flip when it already on the floor on cardboard. I charged the machine with 5 lbs of 134a and started it up. Latter I added 12 oz more 134a. I don't think the heater is working but it sounds good and never rattled much at all. It also didn't cool all that much. The line from the float was frosting and a little of the right evap got cool but watts were only 200. Still restricted in the float. I tried some simi light hammering on the tube comming out of the float with a drift pin and hammer. It didn't make any difference. When working on Travis's Majestic I had better luck if I left it sit first so there wasn't a pressure pushing on the float blockage. With this in mind I shut it off for the work day. Tonight after setting I repeated the hammering. When restarted it ran a while and settled at 250 watts in the end. It is definitely cooling more than this morning. After about an hour the right evap was all sweating and the back of it had some frost, left evap not much. Condenser is also much warmer but not all the way down, bottom 1/3 is too cool. It ran for about 3 hours or more. The dome never got uncomfortable at all. The left evap did cool down some but no sweating. Back of right evap was pretty frosty by then. Its trying but still not all the way open. I hope that with run time and more hammering it will open up all the way.  |

Gill, are you using soft solder on this?

Gill, are you using soft solder on this? Brazed the suction restrictor. Stay brite 8 on the filter drier connections. Easier to get out if the filter ever plugs. |

Travis, that'd be a perfect top for my 2 door cabinet and my CK-35 would be a spare. Have you any more laying around?

Interesting how the DR guys all want to have a CK on the side just in case the DR fails. Us CA guys don't require such things.  |

Doug,
This unit is going on my 48" 2 door cabinet to be sold. Double evaporator units are rare regardless of type.
Chris,
Yes, I have a CK35 unit that would be my emergency spare for the DR3. My main reason for keeping it is that I doubt I could get enough for it to justify selling it. All of my double units came on cabinets with a sizable shipping cost attached. I do love the CK's, but the DR's are the best.
