Hello, first of all, the forum is excellent, I have been reading a lot and I have already clarified many things. I am an HVAC technician and I live in Argentina.
I just bought a CG-1-B16 and want to get it up and running.
My first question is the care to be taken with SO2. I need to rewire and although I am going to do it very carefully and following the coldspaces instructions, I would like to know what to do if a pipe breaks and I start to lose SO2 ...... I basically want to know if I have to run of the place or by the quantities that it carries, it is not dangerous.
Do you have to use any element of protection?
soon I will upload photos
Excuse my English but I use the translator along with what I have learned on my own over the years
Thank you

Welcome to the forum! The CG-1-B16 would be a 110V 60 Hz machine. I think Argentina operates at 220V 50 Hz. Be sure that there is a step-down transformer for the compressor motor, before powering it on. As for the SO2; there is enough gas in the system to cause a problem if all of the gas leaks suddenly. It would cause a problem if all the gas leaked suddenly into an enclosed room. You would want to move out of the room and ventilate the room before going back inside. SO2 is an irritant and will cause sneezing and coughing but it is very unlikely to cause long-term harm to you. It is extremely unpleasant to smell.It's good to work on the unit in an open area. If that's not possible, work with the unit on a rolling work table. If a leak happens, you can roll the unit outside until all the SO2 has dissipated. Sincerely, David |

No sé cuál es el problema de tu Cg. Generalmente lo único que hay que reparar son los automáticos. Tiene el relé de arranque y el termostato, ambos en una caja. Con el uso después de 80 años se quedan sin los contactos de plata en el relé de arranque y deja de andar la heladera. Novela con cuidado, están muy bien hechas y blindadas, no rompas ningún caño, le reparas el relé y tiene que seguir andando por años sin problemas. Es de 110v con un transformador de 220v a 110v. No la enchufes directo en 220v sin el transformador

In the workshop I have a table with wheels and a place to work outdoors. .... I will be very careful but I wanted to take precaution by consulting everything before Yes, in Argentina we have 220v. I know you have to connect it to a transformer The man who sold me the CG, wanted to restore it and says that when I disassembled it to paint then he could not turn it on again and he sold it to me in that state since he could not find someone who wants to fix it |

Well, I started disarming to reconnect and found that they had never disarmed. the wires were broken by the years. The wood is in very good condition and there is little rust ..... When tilting it, liquid could be heard going from one side to the other, so I deduce it did not lose the SO2 charge
I measured the coils to identify which is the common, run and start and they measure well!
also check the windings for leakage and no leakage!
As my big soldering iron broke, I can't solder the terminals to the compressor until I buy a new one, in the meantime I tried to connect it to see if it starts manually and starts up! i tried it for a few seconds and it seems to work fine
Thank you so much for the comments!
I will keep updating

Nice work on the fridge it looks new .
Would like a picture when all done and put together!

Hello, today I launched the cg. It sounds good, the amperage remains stable, the condenser heats up like a normal refrigerator and the evaporator begins to cool after 1 or 2 minutes, and after 20 minutes it is completely frosted as in the photo that I uploaded. I also take the opportunity to upload a photo of the terminal block that is in excellent condition. It is surprising that after almost 85 years everything is in excellent condition, from the wood to the cardboard box that covers the relay. Is there any way to know with the serial number approximately what date it was manufactured? mine is 6388584 Thanks |

The bottom of the compressor appears to be free of rust, indicating that it was never wet. Probably it's been stored indoors by all the previous owners. How much contact life was remaining in the relay? That is often the first part to wear out and require service. Sincerely, David |

Yes, you can see that he was never outside. Also in the area where we are, the climate helps a lot so that things are preserved very well
I have not reviewed the control yet .... Next week I will surely review it

Hello, it's been a long time since I updated this topic but I couldn't do anything, since it's summer in this part of the world, we had a lot of work to repair refrigerators and air conditioning. Now I took a few days off and I started to check the control, first I connected it and I saw that it didn't work, it just clicked and the compressor didn't start. I disassembled it and found that the contact of the starting part was missing, the rest of the relay and thermostat look good I disassembled a commercial refrigerator relay and I was able to remove the contact it has, and soldered it with tin to what remained of the original plate, now it works great. Then it will be necessary to test that the thermostat works but that is for later
