Re: Pump down old Ac to Reinstall somewhere else
Hi pretty easy fit suction gauge on service valve (large valve) Plough unit of measurement onto cooling mode (make certain is running), shut small service valve. You will run across the suction pressure drop as it is getting vary close top 0 on judge quickly close the big i, then plow off.

cheers so much, i will give it a become next week.

Thanks, if i don't take any R22 Guages can you practise information technology without them. I accept R410 guages merely don't require R22 much and then i haven't purchased whatsoever. Last time i borrowed some of a work mate.Cheers
Re: Pump downward onetime AC to Reinstall somewhere else
Yous may require an adaptor for your gauge lines, for this purpose you are simply looking for pressure "0"gauge so gauge type does non matter.

Thanks
make sure when yous re-use on R410a, to give alittle purge with R410a.
Re: Pump down old AC to Reinstall somewhere else
Yous don't need gauges at all in virtually cases of relocation.

Merely turn ON unit on cooling manner and wait until compressor starts. It is proficient practice to run it in cooling style at max set temperature (or in exam mode) for some time (xv min or more) to collect oil from pipes. Close smaller valve and than later xxx-60 seconds close bigger valve. Plough OFF unit and check with screwdriver, that, when you printing valve needle, connexion port has no pressure. Cap it, and that is all.

It doesn't sound like yous install any of the chinese imports, haier/aux/chigo etc or kelvinator/teco conventional non inverters and then.
Thanks, if i don't have any R22 Guages tin y'all do it without them. I have R410 guages but don't crave R22 much and then i haven't purchased whatsoever. Last fourth dimension i borrowed some of a work mate.
Thanks
I'grand amazed about the amount of r22 splits nevertheless sold here.
Re: Pump down quondam AC to Reinstall somewhere else
I usually prefer to reclaim the refrigerant into a cylinder, that manner all the gas is drawn out of the indoor unit of measurement and pipework. If you exit the repossess in automobile it`ll cut out at its max vac setting, if there`south whatever rest refrigerant in the organization still to boil off the repossess unit will restart. Also as you`ll be weighing the gas out yous`ll know if you`ve got the correct amount to put in once again (there`s always the possibilty that at that place`s a slight leak in the system). While equally this is going on you can be disconnecting the wiring, clips etc.

Re: Pump downwards sometime Air conditioning to Reinstall somewhere else
Hullo Aussie install,Some of the members might non agree with what I am virtually to say hither, only It's my opinion, and I am going to risk it anyway.
From what y'all have said in your posts, it seems that for yous there is a clear distinction between an AC installer, and an AC engineer or technician. Allow me explain, I install AC equipment, only then I am besides a technician, which ways that if something goes wrong with the install and the equipment doesn't work (either at all - or just some attribute of information technology), and then I can just put my other cap on and diagnose the problem there and and then. My question is therefore exercise you, (and other members) recollect it is OK for people to install AC having only the knowledge required for the actual install, and little or no knowledge of how the organisation works AND far more importantly, the dangers that are present. Because if that is the example, we go right back to the argument several years onetime now, where plumbers were presuming that they could get into the Air conditioning merchandise.... Which by all accounts they take. Merely tin can we exist totally honest about this, if you lot were the client paying for an AC install (the workings of which you knew FA near), you would I am sure like to retrieve that the people who install information technology know all almost information technology, and tin set information technology if it goes wrong afterwards?
The affair is Aussie Install, if you are working for a bigger outfit every bit purely an install engineer, and so that is fine, because your visitor will have technicians on hand to back yous up if things don't work out... Simply if that was the case, then surely you would be asking one of them what to do... not us?
And then from where I sit, it looks to me like you are working independently, and evidently don't take whatever knowledge of how an Ac operates, considering the question you asked is actually something that any Air conditioning tech could exercise in his slumber. So now several kind souls have given y'all the information you lot needed, but to be honest, I actually don't retrieve that was a wise move.
Re: Pump down old Ac to Reinstall somewhere else
im in agreeance doc,doesnt sound like he is arctic certified to me.one of the first things taught at trade school was how to pump a unit down,in my day anyway.
sounds like youve lost your equus caballus aussie john wayne
mmm to beer or non to beer...........lets drink breakfast

Thank you guys for your aid (some) . I appreciate your comments "fridge doctor" and sympathise where you are coming from, nonetheless y'all don't know my circumstances and therefore only judging past my comments.
A couple of items i should point out.
- Yes i am Certified with Arctick.
- I only install new units, never do whatever piece of work on (as my license does not allow information technology nor do i take the cognition to undertake work) i leave this upward to the real tech'south who have done the hard yards.
-With regards to what we were taught, i completed a 5 day certified form, yes we did go through the pump down procedure also every bit lots of other, nonetheless this was years agone at present, and its like this. If you don't do something often yous plain forget. Im non one to claim i know everything at all, hence i was asking yous guys. And so come on don't criticize when yous merely know half the story (and to exist completely honest, you can continue your comments to yourself).
Paul_h - nah i don't bother with cheap chinese brands, not worth the trouble, plus the R22 ones will be off the shelves shortly anyway!
Also "fridge doctor" an engineer is a big discussion to be using. Anyone can call themselves an engineer! I get this all the fourth dimension, come across what qualifications they have, most take FA.
Thanks over again im in no way claiming to be a Refrigeration Technician, i don't want to exist.
Re: Pump downwards old Air conditioning to Reinstall somewhere else

Yea thats what i said. Also said that i don't accept the knowledge to practise the work.....Some people are funny ones!
Re: Pump downwardly old Air conditioning to Reinstall somewhere else
"my license does not permit it nor do i have the cognition to undertake work....i completed a 5 day certified course, however this was years ago now.... don't criticize .... (and to be completely honest, you lot can continue your comments to yourself)."
That's a big hole you simply dug yourself into. My comments were and
are valid. Past virtue of help and instruction I for 1 volition not help and abet an unqualified person to go and fool effectually with a dangerous piece of kit... sorry, a 5 day course doesn't cut any ice with me.

Re: Pump down one-time AC to Reinstall somewhere else
I've dug no holes, a 5-day course in Australia will requite you enough understanding to obtain a Restricted Separate System license in Commonwealth of australia. Whether y'all like information technology or not that simply life. A restricted license will merely allow new installations, no service piece of work is allowed. And for you who seems a little wearisome, when i am referencing "nor do i take the knowledge to undertake work" i mean i have not done the relevant training to undertake any service work - i mean its obvious isn't it?
"my license does not allow it nor practise i have the knowledge to undertake work....
i completed a 5 solar day certified course, nevertheless this was years ago now.... don't criticize .... (and to be completely honest, yous can go along your comments to yourself)."

You lot've got your views, ive got mine. Lets just exit it at that.
Take a good One.
Re: Pump downward old AC to Reinstall somewhere else
Sorry i hateful the License will allow new installations and decommissioning.
Re: Pump down old Ac to Reinstall somewhere else
Sir... I exercise not want to enter into a slanging friction match with you. But I and many of my peers spent 5 years as a lowly paid apprentice learning the skills of refrigeration and of course air-conditioning.... I can truthfully say that 5 years was just the beginning. I am sorry if you think I am 'slow'. I take 44 years in the industry so perhaps I am entitled. Maybe my colleagues volition comment upon whose view is right... I will be guided by them.
Re: Pump down one-time AC to Reinstall somewhere else
Thanks for your comments, end of discussion.
Re: Pump down old Air-conditioning to Reinstall somewhere else
jolly proficient at present that thats all over with.
any other posters from overseas who want to work here legitimately maybe ai might be able to remember the name of the form that was approved by the Australian Refrigeration Council( ARC ) i dont know what you where certified as aicheers
mmm to beer or not to beer...........lets beverage breakfast
Re: Pump down quondam AC to Reinstall somewhere else
lol, deplorable mate im an Aussie been here all my life if thats what you are referring toOh and if anyone want a listing of courses that will enable them to apply for a Restricted License in Australia then go to w due west w.arcktic.org.
Bye All!
Re: Pump down old Ac to Reinstall somewhere else
ii means of looking at information technology from my perspective.
Aussie fridge has gone to the trouble of getting a restricted licence . still to this twenty-four hours in Aussie there are enough of installs by unlicenced people and i have lost count of the number of warranty jobs ive gone to that were installed by people who have no idea, with wrong superheat and subcooling and a distinct lack of evacuation just for starters.
ive worked on all types of machines from large chillers to small splits and aye i as well get annoyed when i see the licencing aspect of my trade.
but i had the pleasure of working with a bloke years ago who had no licence and no formal qualifications and he was the best mechanic ive always worked with.
in short, i dont know the standard of work Aussie refrigerator does simply he got off his arse and got a licence and he came on this forum and asked for help, i say adept on him he sounds like he cares about the job he does.
Re: Pump downward erstwhile AC to Reinstall somewhere else
