A/C sequence of events

At present I've fitted the rec/drier and it's still sealed (vacuum)
I will be fitting the condenser and pump in the next few days.
At what point do I install the pump oil ie. is it ok to put it in a few days before I can get to the a/c man?
Same applies to the pipes to the rec/drier, is it ok to break the seals and fit the pipes, then wait a couple of days to get it gassed?
Answers in a sealed envelope[:D][:D][:D]

How come your putting the oil into the compressor and not the guy gassing it?
They're a bit different to a car to put oil in, the oil is hygroscopic and a special oil not easy to get hold of if you're not in the trade, and if it gets in the wrong spot you'll pump it through the system.
All refrigeration is extremely sensitive to moisture so I'd be keeping everything sealed as long as possible before heading off to see the fridge guy and in all honesty, I'd be letting him do a lot of the final hook up on the day; I think you'll find it may work out more economical in the long run.

Yes, Bernie: what were you thinking of?
Around here, we do as much as we can ourselves Alan. If the compressor needs stripping,then we take it apart carefully with grinders and hammers and glue the bits back together with fish glue.
The guys gassing it almost certainly need the whole lot spelt out to them. A/c has only recently become popular here so there are a lot of "Specialists" with the minimum gear and knowhow who need watching.

I can only apologise for my actions, as I am not feeling myself lately!!!!!!!!!!!!!!!!!![}:)]Alan
At least my hat is made of wool.[:D]
You forgot the string and sellotape Tom[:0]
I take it Tom you put the oil in yours sometime before it was gassed?

The question I asked about the oil in particular I was very genuine about; Suniso oil is or was the norm and I know of no other oils with the properties.
One drop of moisture the size of a pin head will stop a butchers coldroom and all you need to do is forget yourself and blow on a part & chances are you've given yourself enough work to keep you out of the pub for a week.
Providing you can keep everything dry and sealed, there's no reason you can't hook everything up 12 months before you get it evacuated and gassed; I was pointing those things out previously to save you any headaches, but perhaps you may need the experience to fully appreciate them.

Thanks Alan, Sorry to be flippant. Blame Tom, he started it.
I was supplied with Castrol Icematic PAG 100 oil for R134a systems.

I used Sanden pag 10 oil as advised by the compressor manufacturer, sir, honest I did!

PS.
Yeah I know about Tom; any man who will spend sleepless nights working on a BX has to be sus; I've seen a few suns come up myself incidentally[:D][:D][:D][:D][:D]

As Tom does not want to speak to me because I told on him[}:)][}:)]
Alan, It's going to be differcult to say the least to install the oil in situ, so if I put it in now I take it when the system is evacuated, that's when the moisture is removed?
He did say he would like to evacuate for at least an hour, so I said,what you do in your personal life got nothing to do with me[:D][:D][:D][:D][:D][:D][:D]

I'd already answered your question and am declaring an official tantrum. Just drain the dratted pump and put 135cc of oil in it for heaven's sake!As soon as the oil is measured, close the oilcan and pour the oil into the compressor. Close it again after you with one of the nice green O rings I gave you. Close the open pipe ends off with waterproof tape ASAP and fit the drier last. Ensure it is all tight
and if your engineer wants to draw it down for the full hour, let him!

Done it now.
All finished.
Oil in.
All connected apart from drier, yes I have sealed the pipes with a bit of spit'n'wattle.
Tomorrow is Siberia[}:)]
PS For Sale
90cc PAG oil (only opened once)[:D][:D][:D][:D]
