A SG won't do you much good on a mini-split. Filter dryers? There are TWO examples on Mitsubishi where a dryer can be used - the Pre 2002 minisplits with R22(PUG series)(Still...
Why not just a MXZ 4/8 system? City multi is all well and good, but this is a residential install, and "shouldn't" need the hot gas bypass/concurrent heat/cool that a city multi can provide. Unless...

Just got out of a refresher class - the "Auto discover mode" is strongly discouraged, but IS functional. Is a nightmare on the 8 head unit, can take an hour, and if you fix the wiring, you'll have to...

MSZ-A09NA-1 series. Always replace the bearings if you're going that far, and NEVER place the cover back on until you verify the blower cage is centered properly, after the fan turns on. There isn't...

Sounds like you have a mxz series outdoor unit. Each indoor unit MUST be in the same operating mode, no concurrent heat/cool. Each time the unit reboots it randomly assigns the first ID unit to boot...
Oh, I missed a few o-o.
The reason for running or flowing N2 through a lineset is that it helps prevent scale and oxides from lining the inside of the pipe, which can clog EEV/txv/pistons. Less work...
They left a expended roll at the vapor line of the HP, Sloppy for a 6 year old install. Also "forgot" to insulate half of the roofline, don't know if it was a sub or not.
Oh, spend the money on an...
:grin2: We all needed a laugh dave, thanks :D
Equip proof was 300 on R22, 500 on 410A, all trane gear.
601 on mitzubishi gear, for their 410a.
Just found a leaker for an out of warranty system,...
We, during the days of R22 used #8 on all new construction and retro. Ever since 410A, straight over to 15%
8 might hold, but it WILL leak. Mostly because of poor fit on all new connectors, even...

All manuals. Download them, put them on your laptop. Saved me some headache on replacing a noisy ID blower motor and end-bearing. Still a pain while it's on the wall...

Gives you a good excuse to go inside. And by the heat "working", it must be fully isolated from the cargo area, or it takes a half hour to warm up :censored:.
TL:DR - They're okay, but they have...

We've got 5 of them now.
Pros: 19 to 23MPG fully loaded, Tight turning radius, 480 to 500mi between fillups.
Cons: Turbo issues(Seals, manifold, and solenoid on one rig alone, most have had a new...
Chris - E-mail, found the VFD schematics for this unit on the E-library section, along with the Relliatel data. Might get ya closer..
Running a scroll compressor under 50PSI(410A) 20PSI(R22) with no refrigerant can cause arching, and winding degradation, at least according to Alliance. Its on most of their WCR forums and docs,...
Down for maintenance 1pm to 8pm EST. I'll check my laptop, I have a few gigs saved, but you'll need wiring diag RT-SVE03A-EN and RT-SVE06A-EN, they are very... very large manuals.
I'll check back...
Our commercial site is down, I DO have access up to Light Comm with flow charts and data for Precedent, Voyager and Odyssey, Specifically:

I may have the same ones, so I won't flood your inbox. It shipped from Trane on.. or around 05/04/2007 to FA##### ############## 1st Floor. :cool: Need more, PM

Tranes without LPCOs and the "Green Slimer" when pressures get low. It does happen, in very specific circumstances. On resi gear, you can't place enough suction/LL dryers to clean that mess up. R11x...
I agree with the sentimant, although I have a fun anecdote to toss into the mix.
37 years ago, 3 men started a company. The Owner, The Muscle, The Nerd.
The Owner, through ups and downs has made...
The infamous "Charge assist" crap. Pump to the ID, recover, weld in a REAL suction port, and charge by SH/SC. They made the ChargeAssist to be a hookup, run, unhook. Amb temps have to be... above 70...
C - With very, VERY few exceptions. The term is "No Good Deed Goes Unpunished". So you fixed someone's mini-split/wall rattler. It's 18 years old, the filter looks like a chunk of cardboard, and you...
You're going to need some measurements of the existing fan, sweep, shaft to end, depth, and rotation, all of which should have already been engineered out of the equation.:whistle: Johnstone needs...
I think you're referring to the P70 series HPC.. Stick with the ICM 325 series. No taps into the refer circuit=no future leaks.:grin2: Only negative with the 325 that I recall is the thermistor...
Aside from the CON12XXX connector for the LV terminal strip on the first gens, and the 1/4 turn door screws, they're a good unit. Brace them(Unistrut), though, on horz left/right.:grin2:
We don't get much demand for AC out here, server rooms excluded.
Still liking em, superheat on the fly tells ya if the TXV is under performing. Once ya figure out how to use...
