air conditioning

There should be a schraeder valve under a dust cap on one of the lines. My guess is it goes in there ..... don't know how to bleed out the air at the same time though.

Oh well ..... at least that's a start.

For $80 dollars go to a workshop and get it done , You need to vac out the sistem in you want a good gob , To do that you need a vac pump , then you need to know what amount of gas your sistem needs . You need to make sure you connect the high side to the Compressor and the low side to the recever drier , If you vac the sysyem to quickly you will loose your compressor oil, this will be a disaster . Go and get it done , watch what he does , ask the odd question here and there and next time top up will be easy .

Unless your Qualified it is illegal for you use refrigerant gases that are prescribed substances which specifically includes R12.

This being said I would also suggest that as you are not qualified please leave it to some one who is as if you make a mistake you do run the very good likelyhood of destroying your compressor..... in addition to contaminating the system with moisture, dirt and noncondensibles all of which can also prevent the system from working if you are lucky and which will cost your megga bucks to fix!!
be warned!

incidently max fine for using r12 if not qualified is around $10000.00 in SA and these laws would be similar oz wide

The most common thing I hear on my telephone is
"My air conditioner needs re-gassing".... the most common response from me is "How do you know"???

There are a couple of points here...
1) It is illegal to top up with R12 (If you can find any!) without finding the leak!
2) The bubbles in the sight-glass are not always an indication of loss of refrigerant.
3) If you don't know how to... you probably shouldn't be having a go at it!

If you introduce air into the system, your probably going to cause more damage. Like somebody already said, pay the bucks and get it done right!

And when you do... heres a tip... run the air con a minimum of 10 minutes per day (I never turn mine off...) it keeps the seals coated with oil and helps to stop leaks occurring

Masti,
some 60 series compressors have odd connections for connecting equipment, so you may find the ones you have dont fit and you may need to source adaptors.
are you using r12 or fr12?

Cheers Steve
