Beverage-Air

[rdefouw]

I am working on a Beverage Air CFG74-5 freezer. I took over after the previous Tech was told not to come back after destroying three compressors. I found out that he had mixed R-22 and R-502 in the unit so I need to clean that up. The owner of the store ordered all the parts to replace the entire condensing unit and evaporator coil. They also sent a lls and pressure switch that opens at 185 psig. The original unit does not have these two items so could someone tell where I need to install them.

In the refrigeration mechanics hands.:)

My apologies in advance for this response.

Put the tools down and step away from this equipment before someone gets hurt


Have a nice day!
:D :D :D

Rut Row Rorge!

Please don't take offense at this but the questions you are asking are very basic and they indicate that you are in no way qualified to do this work.

If you are not a tech and don't have EPA certification, you will be violating federal law by opening the refrigeration system.

If you are a tech, you are very entry level and not ready to tackle this type of job. Don't get discouraged, but get some training and grow in the field before you bite of more than you can chew. I would add that given the history you relate on this equipment, you would probably be stepping into a mess that will eat your lunch before it's over.

As a tech and business owner myself, I would have a bit of a problem with the store owner supplying all the equipment and only wanting to pay someone to install it. If he's going to cut you out of the profit of selling the equipment I would either charge him enough to make up for that or I would collect my money as soon as I took the gages off and tell him NO WARRANTY on customer supplied equipment. You don't even know if the equipment he has bought matches or is the correct size. "Danger Will Robinson!!"

I thought that this was a place for a tech to get some answers and not to be put down. But I guess I was wrong. I do have a universal EPA Certificate and I have been doing Heating and Air for 10 years but I do not do much refrigeration work. So no I am not a expert in refrigeration like the rest of you.
So if bothers you that much dont reply to my post.

We're not putting you down. It would have helped if you would have identified your self and your experience level better before you asked the question. Think about it, If someone out of the blue asked questions like this in an A/C forum that you were in, what would you think? You'd probably think they were a homeowner that was trying to save a buck by doing it himself instead of calling a qualified contractor.

Your initial post made you appear to know little or nothing about refrigeration and it would have been quite irresponsible for us to give technical advice to someone who could well have been a burger slinger who was trying to fix his own cooler.

Having stated the above; I stand by my suggestion that you don't get involved in this project. By your own statement the equipment has been problematic and you don't know if the new parts are the right ones or even match. And since by your own statement you have no experience in refrigeration, you don't have the knowledge level to tackle this type of job. Just because you may be a good A/C guy doesn't mean you are qualified to do refrigeration. Refrigeration takes you down roads that an A/C only guy does not typically travel, I know because I have done both for 25 years. This is not a slam on A/C guys BTW, it's just that the two ends of the trade are quite different.

You mentioned that the old unit had a mixture of 22 and 502 in it...what refrigerant will the new equipment use? I'm sure it won't be 22, 502 is now rare and there's no future in using it. Do you know what proper refrigerant for a freezer is now? Do you know which oil to use with that refrigerant? It does matter! Do you know what you will have to do to adapt the old lines to new oils/refrigerants? Are you familiar with POE oil and how to work with it?

That pressure switch...does it open low or open high? The pressure setting you said it has on it would only make sense for one of those applications. And the question is, is it even needed on this system. If you don't know where it goes you can't possibly know what it does or if it's needed.

The LLS, is it even needed? Apparently it didn't have one before so I'm questioning it. Many reach in freezers don't need LLS. Would you even know how to wire it? Do you know what the sequence of operation is?

Maybe you'd like to try and answer some of the questions I've posed. If you can show us that you know enough to have at least a fighting chance of being able to do this job then perhaps we can be of assistance to you.

I agree with k fridge on that.. So you may be albe and certified to handle refrigerants and work on a/c but your working on refrigeration now. Many more controls, do your reserach and find an older tech and learn from him.. Good luck

im gonna tell you a secret,run and i mean run like hell,because you are not experienced enough to do this kind of work,and if you kepp on trying with out learning all the disciplines,then you are going to hurt or even possibly kill yourself or someone else.enough said.:mad:

I have been doing refrigeration and hvac for over 20 years and yes they are two different trades but they are also the same. You still have a refrigeration system, whether its low,med or high temp, you still have 4 basic components . So if you don't know where a liquid line solonid valve goes or a high pressure switch you really should not be working on any of this stuff.

The owner should never be allowed to order parts ;) . This job looks bad and should be ditched, you'll just get more and more problems. Like what everyone else said I guess :D

My first post YAAAAAY!

My family business which consists of my dad (30 years exp), my bro (10 years exp.), and me (3 years exp.).

I once had to deal with a hotel maintenance chief who thought we should come there for free, diagnose the problem, supply him with part information so he could order the parts and have us come back to put them in. He thought the only time should be charged was for repair time. Our owner very guickly told him how things are done. If he wasn't accusing us of sabotaging the equipment during our visits he would ask the techs if they'd like to come back after hours on the side and do the work for like a quarter of what he was quoted. What was really scary was him taking the course to get an EPA certification so he could do the work himself. Horendous.

Well this goes out to all of you who replied to my post and dind't even try to give me any help. I copleted the job and the freezer has been running for a week now without any problems and after I thought about how th cycle of operation worked I soon relized that I had the the answer to my questions. So I would like to thank you all for NOTHING!!!
