Thanks for the info.
I have three of their units, I have never had to use support so it is good to see they will take care of issues.

Default 45.7F this morning!!

The replacement ODU got to the Boston depot last night at 11PM..
It will be delivered on Saturday morning! Before noon.

Today, I did a little thinking about the weight of the Gree Crown ODU..
I didn't really like that extra weight on those little plastic stands.
The right side has most of the weight on it. (compressor side).
I think that side was flexing slightly. It seemed over-loaded.
So, I found an old 4x4 and sawed up a pair of new base stands..

Once I find the optimal location on the 4x4s, I will bolt the ODU down, using the rubber feet..
Just like I did with the Den Sanyo install..

Speaking of the Den Sanyo.. We had to take out the chill this morning!

Both of my MS's are on pressure treated 4 x 4 blocks .

I have seen a lot of pretty heavy HVAC units on 4 x 4 blocks .

Best of luck , my friend ! :-)

God bless

Default The replacement ODU is here!

Package looked good. Inspection is good. No dents etc.
One test I did perform failed on the first try.. The lowside valve was stuck!
(The same guy must have tighten both valves).
So, I had to put some extra leverage on the tool. (See pic).
It wasn't on like a Subaru lug-nut, so came loose after I put 50ish pounds of pressure on the screwdriver.

I wanted to do an over-night pressure test, but the 5/8 flare is leaking.. (didn't leak before)!
When I looked at the flare closely, the edge was asymmetrical.
It has an elongation on one side. I think that's lifting the seal open..

Tomorrow, I'm going to see If I can trim it down and re-try. If it fails, I'll cut it off and re-flare it.
I'm practicing using my 45deg kit and using 3 steps, lifting up the tube after each flare.

Are you using Nylog Blue or refrigeration oil on the mating surfaces ?

I can not say it is a matter of skill or a matter of luck ? :-)

Glad it arrived safe & sound . :-)

God bless

I used plain old silicon spay on the practice stuff. Except when 're-forming'
using the old Sanyo out in the garage. I put Nylog inside and out of the 'training' flare..

Back when I brazed the hole in that old Sanyo, I did make a test loop.
But I didn't have soft copper.. I used 1/2" plumbing pipe, with a tiny flare.
It didn't leak, but I would never use something with such a small sealing surface in a real install..

Not sure if I can save that factory flare. Maybe nail clippers can trim it down to size.
It's not going to start raining until tomorrow evening. (Then rain all day Monday).
So, I've got a lot of time Sunday to fix the problem and start a pressure test..
Might be pressure testing until Tuesday!

Not to say this is the " correct " way . But to clarify ;

I used Nylog Blue on the mating surface of the " stationary " brass fitting , inside and " back side " of the copper flare and inside of the flare nit . Also inside threads of the flare nut and outside threads of the " stationary " brass fitting .

I tightened it down , loosened it off and tightened it down . More than once .

I had obsessed about 45 degree or 37 degree flare . Pretty sure my old Craftsman flare tool was 45 degree .

To me , it appeared , the lubricated surface of both sides of the flare , would form fit to the brass ( the copper being softer ) .

So , to me , it seamed 45 degree or 37 degree would work it self out on its own . Either that , or I had lucked out & the correct flare tool , in the first place .



I started out with 50' rolls of copper , so I had plenty to cut off a piece of both small and large lines , to practice making flares .

Best of luck , my friend .

God bless

Default Rain this morning, so I kept on sleeping!

Re-inspected the 5/8" factory flare and decided it wasn't worth keeping.
Cut it off and had to work upside-down to make the new flare, without being able to see it!
Had to take some pictures from ground level, to see what it looked like..
It's not great, but it's holding pressure.. Got the pressure test started at 11:30 at 205 PSI.
The gauge manifold is in a plastic bag. Raining off and on today, and all day tomorrow.

Note: The pic is large.

You don't have to be an expert to do hvac flares using this tool, it makes perfect flares every single time just leave the copper pipe 1/8 of an inch above the flaring tool and you will get a perfect 45 degree flare. See the tool below.

Congratulations , you said it is holding pressure ! . :-)

That photo looks as good or better than any I have done .

You plan to continue the pressure test until the weather allows you to proceed to the next step ?

Best I remember from physics , the pressure will vary with the outdoor temperature .

God bless
