You guy's make my new years day

thanks. Really great stuff. My install was bid at $7,700, right! Two ton in garage shop 400 square ft. I'm running 90 feet of electric conduit now, started yeaterday. Long time looker short time builder.

Sanyo install

Well, $7,700 isn't real bad for a 24,000 BTU install. IRRC, most quotes are considerably higher.

Maybe after you get the power line and pad in place, you can get a new quote?

Since a basic install on a fully prepared site, might only involve about 2 to 3 hours of actual labor,
my guess is, much of the extra labor cost is from line-set testing & vac.
It takes 'time' to do that part. A lot of that time is just sitting around watching pressure gauges.

Instead of having a licensed Expert do that part, a DIYer can call him in,
after the pressure testing and vacuuming is mostly done.
All my HVAC buddy had to do was look at the gauges, take a slip of beer and turn the hex key.
It's good to be able to put his name on the warranty registration.

The line set 'Testing' phase can go on for a long time, depending on the installer.
Depending on how good the vacuum pump oil is, & etc.
It's not real hard to do, if you have a good chair to sit in..

Installing an airconditioner is not difficult.

This may be hard to take for some. You guy's are my Hero's!

I had a stroke 2004, one good arm and hobble about, nothing stops me. About 25 months ago I started buying lots tools, I do everything. This link is where it all started. How to live for 44 years without a mortgage

The annoying ad below is not the way to go. You need the touch screen back lite thermostat from Home Depot.

The cargo trailer: Take a look at the frame. Don't buy this one.

If you advertise in my space and I don't recommend it I'll comment on it. Looks like I'm going be banned from another good site.

See you'll later...

Hello,

First off, amazing mini split installation thread! Your posts have been extremely helpful to me.

That said, I am just about ready it complete my first mini split install. There is just one thing I am unsure of:

After the your final evacuation, when the micron gauge has stabilized and you are ready to release the refrigerant, what is the process?

Disconnect pump from service port, then unscrew the allen? Or...

Any input would be greatly appreciated!!

Thanks

Xringer · 03-10-12, 11:35 PM

The last step is for your HVAC guy (R410A certified) to perform..
Be sure to get him to sign your warranty card, where it says installer.

I think the best way to do it, is to have a good cut-off valve on your hose at the service port,
1. shut it off, (the cut-off)
2. then turn off the pump.
3. then release the R410A with the hex key. (Both valves).
4. Remove (quickly) the service adapter (using gloves).

If your valves leak a little when turned(like mine),
you might want to shut off a valve on your micron meter(isolating it),
while leaving the pump running (holding a hard vac).

And then start cracking the service valve (liquid line as in the pic),
and then quickly shut off the cut-off valve on the port, when the
first whiff of R410A hisses into the line set.
You will hear a sudden change in the sound of the pump motor.
Once the cut-off is shut, kill the pump and then open both service valves.

Since your hose has a push pin, there will be pressure inside the service adapter.
Use gloves when you (quickly) unscrew the adapter.
If you do it real slow, there will be a loss of R410A. Not good.

You also might want to do another soap bubble test at this point..
If you did a good pressure test before, doing it again under R410A pressures
is not likely to show up any leaks.

In my manual, they said to open the valve for 10 seconds and the shut it,
(releasing pressure into the line set and then locking that pressure in).
so, a second bubble check to be performed.

What model did you get??

Sorry, forgot to respond over the weekend when I saw the post. Xringer said it perfectly. I chose to disconnect my vacuum pump and micron gauge prior to releasing the charge. The issue with this (even though that's how most instructions might advocate) is that there is a loss of vacuum (what's the right word there?) as you fiddle with shut off valves and disconnects. I tried it a few different ways and always lost a bit of the vacuum.

Using Xringer's advice you're continuing to run the vac pump while you're closing off the valves and allowing a small amount of charge out creating pressure in the system before you mess with the disconnects. Once you have a small amount of pressure, air isn't going to get in and you're all set. Then just let enough refrigerant loose to triple check for pressure leaks and finally open the king valves all the way to let all the refrigerant out just as Xringer stated. Then have a beer, your work is done!

When installing a Sanyo ODU weighting over 140 pounds, do not place it on a couple of patio bricks.
They will sink into the ground, and you will have a Leaning Tower of Sanyo!

This bad Sanyo install was done at the Dunkin Donuts in Lexington MA.
It's one of the larger double-decker (dual fan) models.
Note my tisk-tisk look of disapproval..

I was able to make that face, charge up my Eco-Drive (solar) watch,
take my own picture, and watch our bikes (while waiting for our order)!

And, we did 12 miles!
