I want to give my 2 cents about Deem as I worked there for almost a year. They let the dispatchers run the business. They will run you into the ground and you will hate life. They put unqualified...

Looking for some information into Krogers in Ohio. I'm a refrigeration tech. feel free pm if need be. Thank you

They are just using the e2 to control defrost and monitor temps. It's not on a rack, it's got a single condenser on the roof, full site glass btw. The e2 does run a rack as well, but it is another...

Had a call where the mgr got on an E2 controller and graphed a couple of 8 foot produce multidecks and saw that the discharge air being graphed would go up to 43 degrees a times before it swung back...

Got a call to a store that had ice reported on their suction line on the roof. there was some ice on the suction line but ended at the service valve on a discus compressor. Talked to another tech...

I probably should have elaborated more. I've been almost too tired to type lately. The service call started with a facilities engineer who looks up supermarkets remotely via ultrasite and looks for...

I'm wondering if some overfeeding valves are keeping the suction pressure up. Also wonder about bad valve plates.

Well there was no air in the system I had exactly what the temp said it should be. I did have an extremely dirty condenser, which 4 gallons of coil cleaner and a L O T of water cured. :cheers:

Thanks for the replies. I'm a little rusty as well and wanted to make sure I had the process down. I knew I'd find some info here. I have done this process with the receiver and it worked. But...

I'm going to be working on removing air from a rack system on Thursday. Looking for the correct and best way to do this. My experience has been that shutting the rack down and running just the...

Yeah but I don't see anyone chaulking up any answers to this question, which I know will be difficult one to answer and is going to start with a bunch of things to check. First thing I'd try if it...

I haven't had any trouble with their tech support for the past 15 years.

they are defiantly worth putting in place of florescent

you talking about a cpc controller? If you are you should call their tech support at 1 800 829 2724.

sounds like your ice thickness sensor is adjusted so close to the coil it's going into harvest very fast and then recycling.

Yet another good point Crackertech. I'm going to try and be there when they are putting product in that case one morning and see just what it is when it's going in. I might have been trying to...

thanks fella's. I'm going to add a couple defrost and run the a/c down a little. I have most issues with it in the summer. It's about 20 feet from the front door to the gas station and that door...

I got a Structural Concepts reach in Island grab n' go case in a gas station that they complain the product won't hold temp under 40 degrees. Once I get this thing turned down enough on the t-stat...

With the economy being what it is, people are only repairing what they have to and the rest is staying broke. Everyone is slow in Ohio that I know of. Try and hang in there, check with the supply...

Primmers, I'm not familiar with that controller but I am with copeland compressors. Most have a Henry float on the side of them. It's and oil float. I try and adjust it to be in the middle of the...

The medium temp racks are the ones that I have trouble with. They have electric defrost. They have a ipr/holdback valve. tx

Some stores have split, some are not. This one I'm using as an example is not split.

Jpsmith, It is very clear to me now! I was not understanding how the ipr works exactly. I will be putting this to good use.

Jpsmith, thanks for getting back to me. If you want to go to the pro section let me know. I'm not on here a whole lot but I assume there is a limit to the info that gets passes out where anyone can...

It's an equalizer rack, it's about 20 years old. I don't have near the issues with Enviroguard racks.

The racks receiver levels would bounce around all the time 0% to 50% and the colder outside the lower the receiver. Fans cycling and compressor cycling I figured it was normal and it probably is. I...

Ok, your are 100% correct it is not a ''real'' problem. These racks have run this way for a long time. I think that there is some real efficiency to be gained here and thus using less energy. It...

I think your right about the head being too high. There is no pressure drop on the liquid line. It has electric defrost and it does have a heat reclaim but I pump the heat reclaim down in the...

Thanks for the response. The condensers are clean and we are barely ever running any fans. It seems that the distance so far that I have to run the head up to 200psi to keep the liquid flowing,...

I am a Journeyman tech for a large supermarket. I am trying to find out how to keep a full site glass and also always show liquid in the receiver. Most of the systems have r22 in them. The...

The oil is going to migrate around. You say it makes it back and gets one ball floating this is good. If the compressors are showing low on the oil floats, that is less than half or if a compressor...

Yeah, they have a right to get asked why they would even think that too and if they didn't have the balls to get it out in the open then they would be looking for someone new. He is basically...

:eek: Ok, I didn't realize I was so harsh.

Because there is more work for me to do than I can do for one. What dont you understand? What is a feel good post
? You get off on being non helpfull? Well I'm happy for you. I don't hire bad...

That's really impressive. I would still like to hear what it takes besides 14k to properly clean ductwork. I'm not being smart either. What's all involved.

I've never been real picky about a job when I didn't have one. You just have to go out and land one and earn your keep. Move on when you have something more to offer. You will find it's a fair...

Yeah, I hire contractors all the time and I WISH there was more professionalism. I think there is one good contractor in 10 or even less than that! They are a dime a dozen. I bet this tech could...

I bet this is the problem. If it wont pump down could it also be the cro valve, I'm pretty sure most of the KW have these.

No your not the only one. I like 70 too. It just costs more thought and in my opinion you have to size your a/c to handle it.

You can have all the bennies in the world but it aint worth it. IF your techs were good they would go where they can have a life. They are more like slaves and I guess they are stuck because they...

What is it with the steaming piles of a--holes around here? I was really interested in seeing the answer to this question. I'm sure a commercial HVAC tech can be taught to clean ducts...

Ya, I could look at it that way too. Either way it would have to stop.

I read it in this 7 page thread! I wasn't saying anything directly to you or about what you've said on here. No big deal. Some said they don't charge their boss for call backs. That's free labor,...

Do you want me to word it so that you can understand it or did you get my point? :)

Not get paid for a call back? LOL! I'm sorry but you've got to be a real simpleton to think that a call back is OJT or free labor.

She should give it up at least once a week. If you can't get that out of her, then have that honesty talk that was good advice. All women are different in this department, but there isn't one...

This is a question I've often asked myself and I actually left a company doing in house and jumped in a van, I last three months before I found out how this contractor lied to me about hiring more...

I'm not going to argue with you. Re-Read the ORIGINAL post and see where I told her to call a contractor. So I don't need you to tell me to do that over and over because guess what man, I did...

It's for hot air, I think they just cleaned it up good and want to sell her more than she needs. I in no way want to do the work but I'd like to understand a little more about them in there theory...

I'm not sure if your replying to me because I was never reckless and this unit was not under water. I was completely vague on the price, as to what it intailed so if that was wrong, I apologize. I...
