Kinda Sad news about my new (used) Mach II GT.. what should i do?

[lross78550]

After Reading the serial number sticker on the back of the unit it clearly states that the mach II GT i purchased on ebay is really just a plain old mach II the sticker states nvineti (sp) Mach II / Refridgerant R134A and i believe it also list a max cooling of -50C. The add on ebay clearly states this is a mach II GT that uses R404a Freon. i payed $405.00 for the unit plus $25.00 shipping. it appears clean with the display installed and seems to work fine so far. but what should i do? Its my first phase cooler and im sure i will be happy with -50c but how bad did i get burned is $405.00 way to much to pay for a r134a mach II with display (no lian-li kit). I sent the seller a politely worded question asking about the descrepency and im awaiting his responce (if one ever comes). what do you guys think
Thanks

maybe he recharged it with 404a

[Gray Mole]

Well that's definitely a misleading advertisement.

I mean it's still got the same basic 'guts', and a regass to 507 or 402a would definitely be in order (along with a new evap head) to make it shine whether it was a Gt or not.

But for actual purchase value, I'd say it was about $100 more than what you should have paid for it as it's the 'base' Mach2 model, and likely older than it would have been as a Gt.

So yes, the seller should be refunding a portion of your money.

If not, then a claim should be made for the ENTIRE amount to force the seller to either make a concession, or refund and take the unit back.

Sorry to hear it, but I'm sure you'll be able to get something back to cover the 'shortfall' of the unit.

I hope thats the case but i dont see any recharge valves, wouldnt those have to be installed before you could change the freon.... but really im such a noob this is the first one of these things i have ever seen in person so wtf would i know :)

Well There is a way to recharge without installing valves,but I never even seen that mentioned on the forum. And highly doubt that process was used.Even if it was a regass, its still just a modded mach II.

did you leave fb yet ? Wait to see if you get a response.

[Gray Mole]

Yeah it could get recharged and then the access valves removed and brazed shut afterwards, but it's not that likely to be honest.

Most of the time in this case it would be the seller being unaware that it's not a GT model, and perhaps not all that experienced with the units at all and just thinking it was, or someone told him that's what it would be and he/she didn't even check.

Definitely want to give the benifit of the doubt ;) because it's only right to give the seller the chance to make it right, but if the seller is reluctant to help, then paypal claims (if possible), ebay reports, and all that are in order to 'ensure maximum compliance' :D

Thanks for the replys guys, Im going to give the guy several days to respond and listen to his reason for the mistake. As a first unit im sure i will get a lot of fun out of the unit and will try to come to an agreement with the guy that makes everyone happy. If a custom made unit is as easy to seal (prevent condensation) as i have read that the prometeia units are i think i will purchase a unit from our new moderator jinu117 for my second unit. This mach II will at lest give me something to get my feet wet with and then if i havent fried too many parts i will contact jinu117 and order one of his v2000b built in units i think those cases with built in phase look sooo cool. i hate to email him and ask how much they cost though for fear of sticker shock :)
Thanks Again

Gray robinair makes a special tool,a "procees tube adapter kit" that uses rubber bushing that compress to gain access and you then use a ball crimp tool to seal the process tube before you remove the adapter . then you remove the adapter and braze the end.

I use it mostly for window a/c units or if your somewhere its hard to braze or fire is risk thats not necassary or would take undue time or work to elimate.Does save a couple bucks on parts cost,especially if you find out the compressor is shot or something.

[Gray Mole]

Yeah, I've seen that one Walt, I'm thinking about getting one of those too.

For now I just use vampires to evac, and just throw an access onto them after it's done, and mostly I leave that on just in case there's any issues later it saves the time if I need to get into the system again. (edit, NOT the vampire tap, just the access valve)

It's just rare to see anyone sealing things up after a regass and all that, though with an access being a bit of a 'weak link' I'm starting to think about sealing up the systems after I redo them as another precaution as well.

you may want to load test that also, just because the display read cold enough dosen't mean much,if a slow leak developed it can get colder under a no load condition.

If he wasn't honest about............

[wdrzal]

not sealing up units could cause warrenty issues,especially if someone likes to hook and unhook hoses.;)

they make seals if you do want to leave them on.

[Gray Mole]

Yup, that's EXACTLY why I'm considering brazing the access up now ;)

'Oh no, I'd NEVER let gas out to try to get better temps on my unit, honest' :rolleyes:

:p:

I've been trusting of my customers till this point. And no reason to doubt. But if I see some symptons... I might have to be forced to do what you guys are talking about or get those specailized one you can't open without special tools... :P

Give it a little time with seller. And if he doesn't respond back in right way, file claim. And please let us know too when you file claim as we might be able to find who the real person is in forum. (has happened a lot on some forum for troll hunting.)

[expansionvalve]

Another way to go anti tamper on the service ports could be to use some heat shrink over the valve and the stub, im pretty sure there is some heat shrink about just for this job complete with unique serial number, although it's not as secure as braze shut if a unit comes back with damaged/missing heat shrink then you know somethings gone on..

That Idea I like!

you can also buy the no peal stickers that show if it was taken off like Dell/Gateway uses on there case doors and put that over the cap and tube.

[Tekdemon]

Hmm I know I'm about 5 months too late (oh dang, 6 months), but I'm pretty sure that because the Mach II GT used the same compressor as the Mach II, it was using a compressor that was originally meant for R134a.

Because of that, the Mach II GT's have compressors that say R134a on the sticker, even though they've been gassed with R404a.

Anyways, just wondering what happened with this, hope you didn't get into a horrible argument with the seller over this since it was probably a genuine Mach II GT. It'd really suck to be selling your Mach II GT then have someone file a claim against you and leave you with nothing lol.

P.S. How come I'm a noob with 36 posts and I'm the only person to notice this about the Mach II GT? :nono: It's probably cuz the Mach II GT is still exciting to me, and everyone hardcore is all about triple cascades now, lol.
