How to remove compressor from cooler?


Having a hard time seeing the suction side valve, does that isolate the suction side of the compressor or is it just there for the low pressure control. ?

there is no valve on the suction side. The valve next to the compressor goes to a p70 johnson pressure controller

thank you.

I was thinking about another way that should work in theory but i would like your input about it:

If i used a piercing valve on the suction line and connect a manifold gauge to. Then close the valve after the receiver and pump down the system.

The gauge should read between 0 and 1 psi so there should be no pressure or coolant in the suction line and/ or evaporator. Am I rigth?

If there is no pressure, i should be able to cut it and cap it without loosing too much freon?

Let me know if my theory could work please.

Thank you in advance

All I know is recovery cyclinders are yellow for what I do on a daily basis which is air conditioning which utilizes R-410A and R-22. If I need to be certain that a recovery cyclinder is clean when I reclaim and plan to re-use the refrigerant than I pull a vacuum on the recovery cylinder after filling it with nitrogen. There is no distinguishing color for a recovery cyclinder between those two refrigerants and I do not think there is one for yours either, it should just be gray and yellow meaning my recovery cyclinder will be used for your refrogerant as well. Again, it just needs to be absolutely clean.

You just need to make certain any possible other oils or contaminants are cleaned out before recovering your system's refrigerant or it could spell distaster by way of compressor failure. Mixing one refrigerant with another is a big no no.

I would just buy a new jug of 401-A and install all new to be safe. In fact if I were you I'd hire a refrigeration service tech to do this job for you as there are too many precision and specific tools and procedures to have and follow.

You have a brazing rig? A recovery machine? A vacuum pump? A recovery cyclinder? A recovery machine is not cheap but it will pull out all of the refrigerant from that system, it will just take a bit of time. A recovery machine is pretty much a compressor just like the one on top of your cooler but much smaller.

On a recovery you recover into the liquid side of he recovery cyclinder. Btw, you can use a hair dryer to warm up the receiver to get that refrigerant flowing. I'd say a torch as in a brazing rig but you need to really have experience doing that as it can be deadly dangerous so a hair dryer in your case would be a lot safer. There will be refrigerant sitting in that receiver that does not want to move.

Not to say you can't do the job but you do need to have the right tools to do it right. Plus when all of the refrigerant is recovered and the system is empty than you can braze in a shreader valve on the suction line to add in new refrigerant, or the tech can.

I bet you thought to remove the compressor and relocate it was a small task, huh?

There's a lot involved to doing things safely and right in this case or in any refrigeration case.

I'd really like to help you but at this point your best bet is to pay a tech to do it for you.
i understand your point of view but what about trying this:

No it won't work , yes the evap and line to the compressor will be zero but as soon as you shut the unit off and cut the line the pressure will bleed back from the condenser through the compressor and out the line you just cut. I think what you want to do is almost impossible.

If you did it your way with a piercing valve. how would you leak check it after you braze it back together?

soap and water.but for what i have been told, my way is almost impossible because of the pressure eventually building back up or introducing air in the system??
And what about using some of that new quick connect stuff

Have a refrigeration moving Company get it in the door for you, don't take it apart.
You know they have piano movers and Refrigeration equipment movers.

You need to call someone to do this. You are trying to do something that is way over your head. I don't know any company that charges $200 per hour. I would of had this unit pumped down and ready to cut loose in the time it took to read this thread.

would a refrigeration equipment movers take it apart if they have to?

For all i know, a 8 feet tall cooler won t fit thru a 6 1/2 feet door without taking apart

The box itself is relatively easy to take apart. A six in one screwdriver and razor knife is just about all you need.
