Converting Mach 2 to Mach 2 GT..what is involved?

[sashin]

Just have a couple of questions guys. I have a Mach 2 at present and want to have it converted to GT. My current unit works perfectly (the unit is well past the warrantly period as i had purchased the unit from another resellar in the UK) It has done about 1550 hours BUT i want better cooling for my FX55. BY the way i live in Ireland.

Anyway my first question is can i just have Mach 2 regassed with r404a or r507a by any refrigerant chap here or do i have to send the unit to you ,Phil to have it done profesionally.

What changes are made to convert from Mach 2 to a GT?

What happens to the Mach 2 Control Center as the current version i have is 1.23....do i have to update it to version 1.24 even though the control board is still that of a Mach 2?

Does this new Mach 2 GT control center constantly run the fan at turbo speeds as mine (version 1.23) only runs at turbo mode if i enable it in the control center, when i reboot, it remains running at turbo mode untill i restart the control center. I ask this as i have read in these forums that the fans at the front and the rear of the GT units need to runs at turbo modes all the time to prevent the condensar from overheating.

How much does it cost for the whole thing and how long will it take?

Sorry for asking so many questions at once BUT i am seriously thinking of sending my unit over to you (Phil) to have these changes done profesionally if it involves more then just changing the gas from r134a to r404a or r507.

Hi Sashin.

To convert your ST you need to purchase a new controller board for it, which is available from myself. You can get it recharged by anyone with the relevant experience and qualification - I have to say there arent that many people prepared to look into recharging these units, which is why people from all over the world are coming to me. But dont take that as gospel, if you can find a HVAC engineer who is prepared to do it, then go for it.

You could have your r134a unit recharged with either 404a or 507, and you need to use CC 1.24 (runs the fans faster).

I would of course guarantee your unit once all work was complete.

Price wise depends on the situation, and shipping in your case. Email me for further info.

Phil

Thanks for the quick reply i will email you now for further details.

It is great to have one of these phase change units isn't it...

ok, as phil knows, i have just bought from him a GT controller, (which looks identical to my ST controllre?). i've had no problems with the swap, the unit seems to work fine, but for some reason my pc is no longer turning on. i have just put in the Ryanpower 2 psu at the same time. It's really bothering me as i cannot tell whether its the connector to the motherboard having problems with making contact with one of the pins. well the motherboard is lighting up in standby mode. I just cannot work out where the fault is. all the cables must be in the correct format on the GT controller as it starts working as soon as i press the power button on the front of my pc.

Does anyone else have any suggestions?

thanks,

Pete

- i have now put my old PSU back in place, same thing is happening again its still not turning on the pc. - if i bypass the vapour unit and plug the power button directly in to my pc it turns on straight away, must be something not right with the GT controller?

- Update - i have had to use a screwdriver to make contact on the motherboard when the 2nd LED comes up on the Mach II in order to get the pc to turn on.

I dont understand why its not working as i used a multi-meter in buzz mode across the metal pins of the yellow cable at the motherboard end, and when the 2nd led is turning on it is allowing a current to flow as the multi-meter started buzzing?? so whats going on, the motherboard works fine, the gt controller apears to be working fine. but why is it when i use the yellow cable from the controller the pc wont turn on?

Any ideas?

Thanks, Peter Wright

Have you tried updating the firmware which is available from:

I'm sorry but I can't tell you which one you should use, if it does indeed turn out to be the problem, so I suggest you do some kind of search on this forum for "Mach II GT Firmware" or similar.

A common solution to the fault described is the connection between the blue/white wires to the motherboard from the control board. Ensure that both ends are connected properly, and to the correct mobo header.

Another possibility is that the Molex connection from the PSU to the control board. Check that this is also connected properly.

Good luck with it
