Where did you get yours? I'm looking at justminisplits.com. I have a set of gauges and a vacuum pump from doing a car a/c repair a couple years back, so that part should be ok. Do they come with all you need for installation? I read something about needing a power cord, and may need longer line runs than are provided.
Final question- I'm almost through with a 16x20 shop with a loft over the top for office etc. Can I get away with a single system? I was thinking about getting a shinco 18000 btu and putting it upstairs to cool the entire building. It will be insulated, I've got energy star everything - windows, door, garage door etc, so it should be pretty tight.

You need a set of R410 gauges, 410 runs at much higher pressures and the gauge set should not be cross-contaminated between refrigerants.
The mini-splits I purchased came with everything needed for the install and are precharged. The only thing you have to provide is the dedicated 20amp 240v power feed and disconnect to the outdoor unit.

Most of them are pre-charged, from what I've seen. Some have quick-connect line fittings that I believe are pre-evacuated and don't require pulling vacuum on for the diy'er, but I'm pretty sure you could get away with it on others.
If you look at the link below, you see that their lines are pre-charged as well. I was looking at energy star models to take advantage of the tax credit, which the 18k btu shinco meets.

I checked out the 18K Shinco system, it is energy star rated, but that does not necessarily mean it is eligible for the rebate. I didn't see any documentation specifically saying it was eligible for the rebate, most sites do. The inside unit and lines need to be evacuated before the valves on the charged outside unit can be opened. Also, there is a max height difference of only 5ft between inside and outside units. I need a unit that will that will handle a max height difference of 15ft.
I looked at the Ramsond units, did not see that they were inverter units or that they met the rebate requirements. They did show that they use quick disconnects in the lines and the lines, inside unit and the outside units come fully charged. Though they can handle a 16ft difference between inside and outside units.
The only thing i had to buy with my shinco units was the tsat wire that goes from the air handler (inside unit) to the outside unit and then the breaker and the 220 wire at the loc ac shop. It was a easy install. And i got mine from justminispilts.com

Interesting- I thought all it had to be was energy star to be eligible for the tax credit. What a pain in the ***! Also, good call on the lift situation. I'll have to see what the vertical lift is to ensure it will work for my needs.
Justminisplits.com claims that the Shinco 9, 12, and 18k btu models are tax credit eligible:

Good find on the eligibility for the tax credit. Maybe you can find something to verify the lift distances. I found a chart that said 5, but no units attached. All other units on that chart were SAE, so I assumed it was 5ft. Units I found other places were listed at 16.5 ft or 5 meters. In all honesty I would be surprised if it was actually only 5 ft rise max but it is something to check out carefully. In my searching I did find a unit, I believe it was a Daikin, that listed a 64 ft rise max. Seems like the better the unit the more rise it can handle.

I recently installed two of the Shinco inverter heat pumps in my garage. I used a 24k Btu for the garage itself (25x32) and the 18k Btu for the upstairs apartment.
Purchased here:
http://www.invincible-electronics.com/Shinco__DC_Inverter_/cat315965_282575.aspx
The 24k installed and fired up beautifully. The 18k was DOA. It took several phone calls, but they sent a replacement outdoor circuit board and it is now running. It is doing some odd things, so I need to try and call again to diagnose.
Both cool very well, even with the 100F temps and 80% humidity we have had lately. The apartment is 500sf and I probably would have been just fine with a 12k Btu.
Max height difference is 5m. My apartment unit is on an interior wall that required going all the way up to the attic and over, then down. I ran the condensate separately in a way that would provide required fall. Due to the height of my garage, I built a simple wall bracket out of unistrut.
Unfortunately, I don't have any pictures of them. I'll try to take some and post later.

That's a great space. Wow. Looks like a place I could easily live. I think I was oversizing my requirement- Might be able to cool the whole shebang with a single 18k upstairs and a fan blowing down. Did you have to have an a/c tech come charge the lines for you?
Do you mind my asking where you are? Looks like California, but hard to tell.

Looks awesome. I am going to do the same with my garage and upstairs apt. How much rise did you end up with on the upstairs unit? Did you have to go with the 25' linset?
I have been looking at the ramsond units. Mitsubishi claims about a 50' rise with theirs but very expensive.
Where did you get them and were the lines already charged?
I purchased them direct from the manufacture.
As previously stated the units come precharged. Most of the minisplits do.
The lineset are not precharged the unit is. The lineset are just standard copper tube like you normally see, they just have flared fittings and swivel connectors on them so there is no soldering involved. Once you hook up the lines you open a valve on the outdoor unit and it releases the freon into the lines.
Although you technically can hook up and go without an ac tech to do the startup. I would highly recommend have a pro come pull a vac and check your pressures.
Pulling a deep vacuum and holding it will do a couple things, first it will test your connections for leaks, and also pull out any moisture that is in your lineset. Hate to find out after you hook it up that you have a leak and now you have to pay to add freon.
Second is to check that the pressures are correct, which will tell you if the unit is operating properly, and if in fact the amount of precharged freon is correct. I you shortened or extended the line set, then this step is critical.
