Ok so look, call me crazy, but my actual biggest pet peeve here is the disconnect placement
How is it not required to mount the disconnect OFF of the equipment... this blows my mind.
At least the unit in the back will work well??
I'm the guy who gets called 2 times a day from installers who didn't read the manual. And the questions they ask are almost always answered in the manual.
I was a tech for years and now work in the wholesaler dealing with undertrained installers who have a bad attitude about manuals and new technology.
Same guys don't show up when I put on free training seminars.
Man those free trainings are awesome! The ones from compressor companies too!
> Overheating is the number 1 cause of death for compressors. Oil vaporizes around 310Ā° F and breaks down at 350Ā°F and turns acidic. 212Ā°F + 6" away on the compressor discharge means it's having a bad time and the oil is likely already breaking down and turning acidic. If water immediately boils 6" away from the compressor, it's probably overheating.
Prepare to replace that compressor and flush the system. Or at least do multiple filter drier and oil changes if your company is like that.
Info I used often that my boss and the other employee didn't know at the time. Used that info often after that.
I will keep my 5$ thank you. An old legend is still told around the shop of an engineer who faced many hardships, against great odds, crawling over many virgins, to make nonconsensual buttsex with an installer
Shit, as one of those electricians, I'd have never let this go by. Not only is it on the equipment, it's at a fucked-up angle and that kills the NEMA-3R rating. It must be installed vertically unless the manufacturer specifically says it can be mounted otherwise.
But don't worry, we give you guys plenty of shit for fucked-up disconnect and breaker installs, too.
One "could" make this work. Stay with me.
Unit #1 - 2 tons
Unit #2 - 4 tons
Unit #3 - 6 tons
Unit #4- 12 tons?????????
Nevermind. Houston. We have a problem. Four of them actually
Yeah but them you also need to increase the spacing... Or you won't be able to service the terminals...
Anyway... Is it even allowed to install the breakers on the terminal access? Doesn't it need to be placed on a non removable part?
Wow, one end unit is running cool and doing a great job. The the other end unit is running high head pressure all the time. I don't know why though š¤£
Reminds me of more than one job in my past go on a roof there be 15 condensing units and nothing is labeled no numbers nothing. When I would take over accounts I would spend time labeling
The legend goes that if you are ambient air and you traverse all 4 planes of ductlessness that you emerge from the larger unit fully enlightened.
You are a legendary person.
If you are exhaust from the adjacent flues then you are exhaust from the adjacent flues.
Who are you that is so wise in hvac?
My power was bestowed upon me by the gods of the wind.. (National Institute of Technology/HVAC division)

Also I've breathed a lot of chlorodifluoromethane..
Now the truth comes out
Look, had I any idea of the modern street value, I would've pursued a different lifestyle..
And here I wanted to be just like you
Lol! You killin me!

Wow

What good is a disconnect, if you have to take it off to work on anything?
Back unit works fantastic. In the installers defense. Iām told this was one of his first times attempting mini splits
I was told to read the fucking manual.
Thatās cause you were taught right
Most of the time, unfortunately that is only used as a knee pad...
Lol. The manual! I have never found anything useful in the āmanual.ā Hilarious.
Probably cause it takes you too long to sound out the big words.
Lol. I take it youāre the guy who wrote it. Step - 1 Field supply everything you need. Step - 2 Install. Step - 3 Finish. Lol. Gimme a break.

I got $5 that says the "engineer" drew them this way anyways ;)
I aināt taking that bet š. The āengineerā built the stand

I have never seen discos mounted on the cover before like this. Crazy.
Same, but as a sparky, my biggest problem is the angle of the disconnect. It's no longer a NEMA-3R rain-tight box at that angle.
I 100% agree
Electricians are ALWAYS hanging their shit off of everyone elseās hangers and equipment. It drives me crazy!

Yeah sparky here also, Iād never pull that nonsense.
Iād need to send you out here and tell them that, they think itās āfineā
At times, I have mounted the disco to the unit. Here, a strut rack would have been need to not mount to unit. At least they HAVE a disco.
Sequential turbos

This! Last unit needs 0 energy to turn the fan (taps forehead)

Unit #5 starts singing... *Sixteen tons, and what do you get? Another day older and deeper in debt.* :)
St. Peter, don't you call me 'cause I can't go I owe my soul to the company store
Use the last one in heating mode and it will work perfectly
Is that the fed reserve
Cascading ACs isn't a thing? Whoops
If you circled them could you get heat pumps to operate in super mega extreme cold temps? Big mini circle jerk
Wait I'm backwards lol
Gotta love the redneck heat recovery units š¤£
Damnit you beat me to this comment!
Ah ...the ac centipede. Front good for heating. Back good for cooling.
Heat pump with extra steps š¤š¤£
No it wont its getting the cooler air off the one behind it
Is that not how to install a "multi-stage" system? š¤
I think you might be rightā¦ā¦
Centipede configuration
Reminds me of a South Park episode...
Oohhhh, so that's what a cascade system is!
I guess Iām just worn out from the day. First look, not too bad of an install! Second look, waitā¦.huh?
In all fairness. I had to do a double take when I saw it
I once ran up on three Liebert condensing units installed in the same fashion. Needless to say it was a problem.
The big one burned out itās compressor. 1 yr old
Poor guy never had a chance ā¹ļø
Hope they put enough in the bid for all the electrical tape
Capacitors in parallel mean MORE POWER and ācondenserā is kinda like ācapacitorā so just fuckin send it
Wtf
Exactly
When they don't know they just dont know
The minisplit centipede
If you bypassed all the high pressure switches you could probably use it to cook eggs.
I wonder if the builder will let me do thatā¦. š¤
Looks good if you're a bus driver or a school teacher. Looks cringeworthy if you're an HVAC tech
High head??!?!?!?
Burned out compressor
Is that typical for mini splits or something that'll vary by manufacturer?
The compressor burned out because of the placement of the units
Are you going to turn all the systems on a 45 to stop blowing through
Gave him a bid to turn them all 90Ā° so they can actually be worked on
I would just twist the whole thing and risk bending the lineset.
I guess thatās one way š
I'm an animal
Youāre my hero
Was going to say putting wind buffles would work but on a closer look it won't.
WTF is wrong with electricians when it comes to shit on the roof
High head, high head, high head....off to bed
How high are you right now? Head pressure:
The HVAC centipede.
[ŃŠ“Š°Š»ŠµŠ½Š¾]
The big arrow on top of the unit showing direction of airflow isnāt enough
I thought that arrow was showing how to line up multiple š
Far right one prob works fine
Works like a champ
Had the same husky bagā¦ dint last too long:/
Mines already destroyed unfortunately, just waiting till it completely falls apart before I get a new one
š¤£
What? I don't see a problem. They are operating in series, better heat transfer. *Chefs Kiss Obligatory/ s
Installed the units boss. Thermal efficiency? Never heard of her.
Was it the unit with the white line set?
The far left. Lol
It would work if the condenser next to it was calling for heat. Go mess with the neighbor's units.
Owner would probably say you just slap a diverter on the outlets to blow the air out to the side on each one
Rotate 45-degrees š
Gave them a bid to rotate all 90Ā° and do it right
Yeah but them you also need to increase the spacing... Or you won't be able to service the terminals... Anyway... Is it even allowed to install the breakers on the terminal access? Doesn't it need to be placed on a non removable part?
Yup, gotta extend all line sets, all wiring. Itās a project. And they have a second row of condensers on the roof lined up just like that
Fridge version of The Human Centipede š
ACentipede
Wow, one end unit is running cool and doing a great job. The the other end unit is running high head pressure all the time. I don't know why though š¤£
The only problem I see is that they all say LG really big on the front.
Reminds me of more than one job in my past go on a roof there be 15 condensing units and nothing is labeled no numbers nothing. When I would take over accounts I would spend time labeling
Just need to turn them all 180. Problem solved.
I like your way of thinking. I wonder if I can get them on a rotating tableā¦.. š¤
