That drain trap is there because the freezer will pull the cooler air thru the drain line.. one call I had before was freezer w/I looked foggy in box. Found freezer coil pulling warmer air in and causing that. I know its rare but after we put a trap on cooler side it fixed the issue. Great video.
Are there any issues if you use a new R448a compressor and condenser with an old evaporator that was used with R22? Does the evaporator need to be designed to use a specific refrigerant? Do you need to purge the lines thoroughly before you hook up the new compressor?

Great install and like others, you really got my curiosity when you mentioned that external protector. The Emerson app didn't have anything, but I did find the Application bulletin for the RST series compressors...it's very interesting: Three Phase Scott-T Motor Design Note that the RST70C1, RST80C1, RST97C1 and the RST10K1 in the TA5 three phase motors use a modified "Scott-T" connection and don't have equal resistance on all three windings. Two windings will have equal resistances and the third winding will be lower than the other two. See Figure 7. Carefully compare measured motor resistance values to the two different published resistance values for a given compressor model before replacing the compressor as being defective. Due to the nature of the Scott-T construction there is an inherent current imbalance in the motors that is much larger than what is seen in a standard 3-phase motor. Effectively you will have two terminals draw similar currents while the third will draw a higher current. The current draw on the Scott-T motors as shown in the performance data and in the operating envelope (available online at www.emersonclimate.com under the OnLine Product Information link) comes from the two main windings. The Scott-T motor in the RST product line uses both an internal and external motor protector.

I didn't realize, but sporlan instructions say you cannot install a solenoid valve in vertical position. I saw the original Emerson solenoid in vertical position. That drain is a mess, they are causing water to back up in the freezer drain by putting a ptrap right there. Nice install, the Tecumseh units do look bitchin nice

We’ve put in over a dozen of those Tecumseh condensers in the last couple months with Follet ice machines. They are nice units. Doin two on Sunday! Double pay baby. 👍🏽
It would be OK, if it was wired back to the contactor coil. Methinks they have monkeys working in the factory, mistaking them for single phase units BEFORE the labels go on. Nothing really surprises me anymore, not even in retirement.

The overtemp safety switch on the 3 phase supply should have been wired into the motors control circuit so the load on that switch would be minimal and the motor would be discontinued without any problems, the overtemp switch could be in the over presumed circuit or the feed to the contactor 🤔
Hey buddy! Just wanna say that I love the videos. Lots of good content and situations that I dont normally see on the residential side. I was curious after watching a few videos if you charge with superheat and subcooling? I constantly hear you say "i filled till the sight glass was clear". Im not saying that doesnt work. Im just curious if you ever charge with other methods. Like this video for exsample, you did a compressor change out as well as noticing a likely TXV clog. A check of subcooling (assuming your condenser fins were clear) would have suggested a clogged metering device or filter dryer. Agian, with you needing to change the evap coil, it didnt really matter either way. Do you braze with nitrogen as well? Your really thorough with your work and i appreciate your workmanship. If the industry was full of guys like you, we would be much better off. Keep making great videos man 👍👍
Man that's insane that factory external overload on three phase compressor ! it should be obvious for previous techie who start up or replace compressor should know this one ! it will be interesting to see autopsy on compressor ! I like your style work and nice video as well. Good work, sir.
We had a 12 or so foot coffin freezer for ice cream at the 4 aisle 2 check stand mom n pop grocery store where I worked as a butcher far as I know it had the same compressor running it for 33 years til one day it just up n quit on us.
@@HVACRVIDEOS thanks for the reply! I'm very new in the field of refrigeration but i work for a company that does military base grocery stores all the time. large rack systems with 12 or more compressors for the freezer walk in along with the freezer reach ins in their respective aisle's. Same goes for the medium/cooler temp systems. Sorry to get off subject but I like ur videos very much because they help on my side of diagnosing the large/loud systems i work on from time to time.
Good video ! That's crazy what u found there. single phasing that compressor when it trips the overload is absolutely stupid ! Wow ! You've got me thinking now , How many More compressors in the field are like that ? ive got a client that has two small 3 phase units ( Heatcraft units - see maintenance video from a few days ago ) that are Quite Possibly like that. ive got to Replace the Defrost clocks on both of them soon. ill be opening up the compressor wiring also at that time to check for this flaw. id Like to call copeland and ask them What are they thinking ? A side note --- i NEVER Use FUSED DISCONNECTS on 3 Phase units any more For this same reason. Blow one fuse and single phase the unit ? i think not. i use Non- Fused disconnects. i Let the Breaker do its Job and Trip ALL legs. You can only Do this Of course When One circuit breaker is Feeding only one unit. also u need to size circuit breaker at Units Max Fuse size for Proper Protection.
I remember Carrier had a bunch 3 phase of rtu's that had fuse blocks after the contactors. I could never understand the thinking behind that, like a design engineer thought of that🤔
What do you mean "fuse blocks after the contactors". If it is AC current, there is no "after" or "before" with electrons running through a wire/fuse/contactor
That’s funny you said tucumsey ( I should know how to spell it) is quality. On residential refrigerators the 04-05 Amanas the bearing seizes up during higher compressor temps. When I see that Indian head I just order a compressor by default 😂
Wondering if the point of the thermal overload was to deliberately single phase the motor, causing the current to increase on the remaining two phases and trip the circuit protection? The current on the remaining two would jump to 173% of normal or more, which would hopefully trip the circuit protection assuming it was properly sized. Still, seems like a bad idea. Must have been a cost consideration.

Good Stuff Chris . I honestly think Emerson is going to crap 💩. Tecumseh makes solid units. I’ve seen those condensing units at Allied . How are you liking the 448A refrigerant ?
Actually it still Has 2 phases of a 3 Phase motor. The Compressor Will Most likely stop turning ( unless it lost all its refrigerant charge ) then it may continue to turn. But , not for too long. That's NOT how u want to stop a 3 Phase Compressor. it actually Has 2 Wires with voltage still Applied to it. They WILL continue to Draw Current / High current at a rate of 2.4 times thier original Rla current. If the Motor windings don't have internal thermal protection , the windings WILL Continue to draw High current trying to turn the compressor motor , unable to do so , They WILL Burn open.
I liked your asnswer . It made me understand it better. So, are you able to wire a thermal overload to a single 120v compressor? And then are you able add thermal overload to a 208V 3 phase compressor or how would you do it if you can?
@@mr.g9366 if the Compressor has no internal overloads, I would put a Motor Protector on it this will sense Phase Loss, Phase Imbalance etc much cheaper than a burn-out !!
What's Crazy is I watch your videos so much that this particular 1 popped up and I was thinking yea, you were gonna do that, but I haven't seen the footage. Excuse the run on sentences. I'm a HVAC/R Mechanic, not a English Major. 😆 😂. Be safe Bro.🙏✌👍💪

The single phase overlaod is fine, the producer of the unit should have used the overload as an interrupt switch on the compressor contactor coilfeed. Not in series with one of the phases. So design flaw on the unit producer, not the compressor producer.
Yea that's crazy someone messed up at the factory. Putting an external overload on a 3 phase compressor. I never seen that one. Where is the quality control.
Just I wanted to mention this your were saying I think was accidentally saying you can’t have thermal overload on single phase I think you were trying to say 3 phase instead
A thermal overload which only breaks 1 phase? What? Thats the sort of crap you see after a 'buddy' has 'fixed' something lmao. Also i cant help but feel its a bit pointless the thermal overload being outside the compressor housing in a little rubber boot aswell.

Why wait a day or two to adjust the superheat?? I can’t imagine that small box take more than a 1/2hr to an hour to satisfy. I’m just curious what your thoughts are considering an underfeeding TXV (High superheat) potentially caused the compressor failure in the first place...
I find you need to give it time, honestly the new valve didnt even need an adjustment but on new installs I always do a follow up a day later just to check on the entire system anyway
HVACR VIDEOS Thanks for the reply. That makes sense that you at least did a preliminary check during startup and finalize it after a day or two. I very rarely get additional time for a follow up on an install or repair.
There's no way that thermal overload came from the factory like that. If it was mounted on the compressor then it most definitely was meant to be in the contactor control circuit and someone else rewired it that way thinking they knew better. We all know engineers come up with some shit ass designs, but none are that bad to put a thermal on one phase of a three phase motor / compressor.
Yeah it actually is factory I cut the compressor open and did a bunch of research there is another overload inside too... its definitely a weird one though
At 3:22, Chris is like (FML) hearing the short cycling
"Don't touch anything without a reasonable cause," the first thing I tell dudes around me that don't know about package units.

Great install and like others, you really got my curiosity when you mentioned that external protector. The Emerson app didn't have anything, but I did find the Application bulletin for the RST series compressors...it's very interesting:
Three Phase Scott-T Motor Design
Note that the RST70C1, RST80C1, RST97C1 and
the RST10K1 in the TA5 three phase motors use a
modified "Scott-T" connection and don't have equal
resistance on all three windings. Two windings will
have equal resistances and the third winding will be
lower than the other two. See Figure 7. Carefully
compare measured motor resistance values to the
two different published resistance values for a given
compressor model before replacing the compressor
as being defective. Due to the nature of the Scott-T
construction there is an inherent current imbalance
in the motors that is much larger than what is seen in
a standard 3-phase motor. Effectively you will have
two terminals draw similar currents while the third
will draw a higher current. The current draw on the
Scott-T motors as shown in the performance data
and in the operating envelope (available online at
www.emersonclimate.com under the OnLine Product
Information link) comes from the two main windings.
The Scott-T motor in the RST product line uses both
an internal and external motor protector.

Good Stuff Chris . I honestly think Emerson is going to crap 💩. Tecumseh makes solid units. I’ve seen those condensing units at Allied . How are you liking the 448A refrigerant ?
Nice work boss
Thanks bud
if it has only One Phase
well ..
it won't run, will it ..??
Actually it still Has 2 phases of a 3 Phase motor. The Compressor Will Most likely stop turning ( unless it lost all its refrigerant charge ) then it may continue to turn. But , not for too long. That's NOT how u want to stop a 3 Phase Compressor. it actually Has 2 Wires with voltage still Applied to it. They WILL continue to Draw Current / High current at a rate of 2.4 times thier original Rla current. If the Motor windings don't have internal thermal protection , the windings WILL Continue to draw High current trying to turn the compressor motor , unable to do so , They WILL Burn open.
I liked your asnswer . It made me understand it better. So, are you able to wire a thermal overload to a single 120v compressor? And then are you able add thermal overload to a 208V 3 phase compressor or how would you do it if you can?
@@mr.g9366 if the Compressor has no internal overloads, I would put a Motor Protector on it
this will sense Phase Loss, Phase Imbalance etc
much cheaper than a burn-out !!
OL should cut the control circuit to the compressor coil on 3 phase.
Exactly ..!but we do not have a wiring diagram to work with here
I have seen a compressor like that before WILD
Big Bro? Did you ever cut open that compressor on this call?
Yeah I did I need to edit the video down and post it
What's Crazy is I watch your videos so much that this particular 1 popped up and I was thinking yea, you were gonna do that, but I haven't seen the footage. Excuse the run on sentences. I'm a HVAC/R Mechanic, not a English Major. 😆 😂. Be safe Bro.🙏✌👍💪
Thanks for watching, I will be going live on RUclips this evening 5/13/19 @ 5:PM (west coast time) to discuss my most recent uploads and answer questions from the chat. Come check it out if you can ruclips.net/video/tQb9QK9LnH4/видео.html
Very nice condenser. I too am hamstrung by chains buying their own equipment. Most times bare bone stuff. At least it gives more opportunities to make money off the things they need that a better version of the unit would have came with already installed
absolutely ..
they cut you out of the equation, soooo..
make thme PAY for Service
Love Larkin
Nice!
Nice video
From india
Great video.
Thank you for sharing the good knowledge!
👍
Chris did you grab beer after this service call lol
I wish!!! Thanks for watching, I am going live on RUclips this evening 4/8/19 @5:PM (west coast time) to discuss my most recent uploads and answer questions from the chat, come on over and check it out if you can. ruclips.net/video/rIuKPCTRMEc/видео.html
The single phase overlaod is fine, the producer of the unit should have used the overload as an interrupt switch on the compressor contactor coilfeed. Not in series with one of the phases. So design flaw on the unit producer, not the compressor producer.
Yea that's crazy someone messed up at the factory. Putting an external overload on a 3 phase compressor. I never seen that one. Where is the quality control.
Apparently it doesn't exist..... thanks for watching bud
Just I wanted to mention this your were saying I think was accidentally saying you can’t have thermal overload on single phase I think you were trying to say 3 phase instead
A thermal overload which only breaks 1 phase? What? Thats the sort of crap you see after a 'buddy' has 'fixed' something lmao. Also i cant help but feel its a bit pointless the thermal overload being outside the compressor housing in a little rubber boot aswell.
It's just a phase they are going through. :D
Are you planning open a training course ? i will take it rightaway.

If the thermal overload ran back to the contactor I would understand it, but dropping out 1 phase is crazy.
Funny you’re there to work on the left unit and the right one starts short-cycling
Number 1 boss
Can you actually go TOO BIG on a solenoid?
Yes you can sporlan just had a podcast on it today, if you can come on over to the livestream today and we can discuss it a little more.

Why wait a day or two to adjust the superheat?? I can’t imagine that small box take more than a 1/2hr to an hour to satisfy. I’m just curious what your thoughts are considering an underfeeding TXV (High superheat) potentially caused the compressor failure in the first place...
I find you need to give it time, honestly the new valve didnt even need an adjustment but on new installs I always do a follow up a day later just to check on the entire system anyway
HVACR VIDEOS Thanks for the reply. That makes sense that you at least did a preliminary check during startup and finalize it after a day or two. I very rarely get additional time for a follow up on an install or repair.
Laughing at how good you are
Sounds a lot quieter.
P-trap should stay on the freezer drain line.
👍👍
WARM BEER!!! PANIC PANIC PANIC PANIC PANIC.........

Would be better if you go step by step when you replacing any bad component..Tnx
There's no way that thermal overload came from the factory like that. If it was mounted on the compressor then it most definitely was meant to be in the contactor control circuit and someone else rewired it that way thinking they knew better. We all know engineers come up with some shit ass designs, but none are that bad to put a thermal on one phase of a three phase motor / compressor.
Yeah it actually is factory I cut the compressor open and did a bunch of research there is another overload inside too... its definitely a weird one though
@@HVACRVIDEOS Wow! That's just crazy they shipped it like that, insane. Hope the internal switch wasn't on the same phase, lol
V
Betcha that thermal overload killed it!
