EG4 Mini-split kinked one of the copper line sets

I ran into this problem on an uncharged line. I cut out the kink and reattached the lines using Pro-Fit Quick Connects. Just make sure you have the right size the spec sheet is not always accurate.

Yes been making a lot of progress, I'll get some pics to update the thread, but i like to joke that I've become an amateur HVAC enthusiast :)

Basically repaired line using 1/2 brass coupler deal, flaring the end. Did a pressure test, learned how to use the vacuum pump, learned a lot of really interesting skills. Sure could have saved money by hiring a local HVAC tech, but i want to know how this works, as much as i can.

System is basically working but i don't want to say that 100% yet, can't any water to come out of the drain plug so checking that today. AC worked great during testing yesterday for about 30 minutes to an hour, and then the same for heating. That is when i realized no condensation was coming out of any of the drain plugs, the one on the outdoor unit, and then the one connected by hose to the indoor.

Lets see what i can fix or break today

There’s a drain plug on the outdoor unit (condenser)?
 
I've noticed initially, they may run several hours before the condensation flow gets started. Humidity matters too. That would be from the INDOOR drain on A/C, and OUTDOOR on HEAT.

Does anybody else have experience with Pro Fit (Sharkbite for A/C lines). Looks interesting.
 
Follow-up - I have two EG4 24k units waiting to be installed. Need the extra lineset for at least one of these. Has anyone found a solution to use a 25' lineset? I know a tech will need to add more charge to the unit. I am trying to avoid splicing the line sets. These are about perfect w/ the exception of 25' option for lineset. I would pay an extra $250 a unit for that feature alone. Can actually get the unit away from the house properly and out of the sun. 16' too short.
 
In this video around 8:20, guy says he contacted EG4 and they offered him "dry" lineset extensions, not charged or evacuated, whatever the DIY versions of these have. I am sure MANY of us would like to know if that's true.?

I will be looking into this.

Hi Jared

I have reached out over e-mail. There is no phone number available on the eg4 site. I'm kinda stuck in 105F temps part of the day until I can get this resolved. I can send you my phone number over messenger. I posted on the contact form on eg4 3 days ago with no response. Thanks - Brock

I'd take a dry lineset option anyday. Vacuum would be needed and a tech onsite for $300 or so to complete it. At least the condenser could be located in a better situation.

Yup that is working, its on the bottom, and the other drain is also working now from the indoor had unit. just had the hoses kinked, seems like i like to kink things alot when installing, have to be more careful
 
Okay everyone, i have had this running now for the last 3 days, and well so far so good.

Spent a huge amount of time but that was okay as i was having fun.

Basically we cut the kinked line, flared it, then added a coupler, and that held.

Then i was able to figure out i needed to pressure test the lines with nitrogen, we got it up to 500psi

Then we were able to do the triple evacuation, and released the refrigant from the outside unit.

And its been working :) I'll try to post more pics and longer description later.

I wanted to thank the users on this forum for getting me where i am. Thank you all!

I owe you all a very nice thank you! I appreciate it all, as does my wife, and little wiener dog named Lucy :):)

Now i'm thinking of just getting some of those cheap chinese no warranty mini-splits versions from alibaba or aliexpress, they are about a 1/3 of the price, buy a pallet of them and start installing them everywhere i want. Hell after spending the last month working on this one, i feel like i can do anything! LOL :) Plus i have all these cool tools, need to keep using them :)

I'll send some pics in just a bit, incase anyone wants to see the crazy install i did.

Next week i'll work on how to test the system, make sure i'm getting the most i can out of it, etc

Well maybe it identifies as a "heat pump" in the winter.
 
500psi pressure test? You're lucky it didn't explode. Evaporator tubing is quite thin these days and not rated for that pressure. Glad you got it working.
 
Then the pre-charge might need to be different for each set. However, not sure how much of a difference a few feet actually makes on a mini-split.
Only if lines are over 25 feet in length. Read the manuals, just about every single manual will state the unit is pre-charged for 25 feet or less of line.

I've lengthened line sets, shortened long line sets. It is in the manual how to compute if additional refrigerant is needed and how much.
