Love the Amprobe. Takes sime practice but when you get it, works great!!

Just checking back in another note went up to them yesterday had a bad contactor on one of the HP units still cranking out cold and heat not even an ignitor out just like the energiser bunny keeps...

Have been checking hgb in diff books but am heading now to the sporlan site

With the old system it was set up with soleniod valves and thermostats, on each case. when one was running, it just ran, I have been concerned with it for quite a while, when it was running under a...

The head pressure is not a problem am running a water coil so I can set the Head at whatever I want and with fresh water it will stay with a head press water valve

I see your point, thanks for all your time and info, by the way, can you direct me to a web site that shows a chart for H.P. to BTU. conversions been looking but copelands website is hard to follow...

Could I not do the same thing with a manual epr set to the pressure/temp differential to control the temp of the evap.? and just leave the compressor running all the time only using the solenoids to...

From what the store owner tells me the Tyler guy walked in and sold the units then told him the compressor was just fine. then walked out not to be seen again. you have to undersand the nearest town...

So what I am reading here is my compressor ACA-031A-TAC-800 will not have enough btus to run the cases? and my copeland rep doesn't know his stuff.the three cases are going to run,as freeze said...

I told him about all three and gave him the numbers from the tyler site and the size of the Friedrich cooler

the N3M tyler is 12 ft and is for fresh cut meat the N6D is an 8 ft for deli. and cheese the friedrich is also a deli case so i am guessing a 34 degree discharge temp it is also an 8' case with three...

the two tylers are N6DHPM, AND N3MGHP.What do you think my risks are to just putting suction line regulators on each of the units and letting them run, especially since they pump down on the off...

can you elaborate on the suction cutoff unloading? are you speaking of a single regulator before the compressor that is shaped like an L and has an adjustable hex screw under a cover on the front??...

why do people say they found it in the last place they looked? of coursi its the last place, if they find it why keep looking

have a local grocery store replacing a 20 ft meat case with a set of two upright display cases. on a single compressor, o by the way have a lunch meat case also on this compressor, so will have a...

WOW What a Thread!! Its a good thing this is not a football site or a ford chevy site it could come to fisticuffs!!!
LOL LOL!! Seems to me the install has as much to do with the longevity of a unit...

Yes have been doing this with the ballast valve but have not tried changing the oil half way through. this may be an answer thanks. will try.
I do change it after every vacuum that I do.

keep it...

Getting some calls for work on these. never a high side valve only low. How can you charge these units efficiently without a high side line tap? most of them are old 12 units switched to 401a. most...

comming up on year two. not even a hiccup. fired them up and never looked back. Been installing goodman from day one and before, many janitrol units before that.have a great success ratio. doesn't...

I have found T's on the exhaust to be invaluable, on cold crisp nights it lets some of the moisture to escape straight up instead of down or condensing on the end of an elbow and freezing. JMO
