Thread: Help-Mouse ate my fujitsu split system head aircon electronics

Learner,
Fujitsu, a Japanese company, used the word "putty" in its installation manual, a manual which was written to be distributed to many English speaking markets. You've also correctly idenntified that this word has many and varied dictionary meanings. However, when used in the context of building work and air con installations in Australia "putty" is not used. There is everyday language, slang, legalese and technical jargon. People in certain industries/professions/trades use technical jargon because everyday language is not sufficient to communicate the intricacies of their specialisation. In the context of building and air con installations "putty" is not used for sealing air con unit service penetrations. It may be used for stopping holes in timber prior to finishing (but rare nowadays) and it sometimes still gets used for glazing work in timber frames (but it's mostly been replaced with timber beads and a smear of silicone). Quote the manual or the dictionary all you want, but book knowledge doesn't equate with real life training and knowledge.

By the way, what makes you think a mouse crawled up the service duct and into the wall cavity to chew on your cabling? It's much more likely that it was already in your house, either in the ceiling crawl space or under the floor and accessed the wall cavity from there.

You are a rare breed. They mentioned the other day that Fridgys were the number one listed in the skills shortage. There should be plenty of work on.

Is it even possible to use a torque wrench on a flare nut???? I can't see it, you could use a crow's foot wrench - a bit like a short open ender with a square opening for a 1/2" drive but this would lengthen the effective lever and make the torque wrench setting incorrect. I'm not a fridge mechanic but I've rebuilt a fair bit of machinery and fitted high pressure dive compressors as well as brake lines and gas lines and refrigeration systems etc all with flare nuts. I can't imagine using a torque wrench in preference to the feel of the fitting nipping up as you tighten it. A torque setting would assume that all the pipework used had exactly the same hardness so that it would seal with the same torque every time. I don't think I'd trust that the metallurgy was that consistent.

Learner,
As all your facts so far are based on web learning, perhaps you should look at the ArcTick page and check the requirements for an AC installer.
He is required to have a vacuum pump.
If you can find a cheap vac pump in Australia, I suggest you buy them all and sell them to tradies.
Is the vac pump you referred to OK for all refrigerants or do we need a different one for each type.

Can you please let me know what you do for a living so I can do 30 seconds of internet research and have a crack at your job too!

Cheers, Jack

Yeah, and I'm a sparky too, I should be getting paid in blank checks

It's pretty hard to make money as a fridgey, there are blokes like everywhere who have a split installed and then think hey, all I have to do is read the manual, use a couple of torque wrenches and plug the vacuum cleaner onto the pipes somewhere and all will be fine

Cheers, Jack

And may I confirm every word said.

Thanks. Now have a crack at my job.

My job is auto electrician. I work Toyota car Service

Well what do you know, I'm an Auto Electrician, Electrical Fitter Mechanic and have a full ArcTick RAC/Auto aircon licence.
Do you have any experience on auto A/C's?

Any news on those cheap vac pumps yet? Are they OK for all refrigerants and where can I get one for $15

Cheers, Jack

I would be also be interested in one for $15. If it isn't suitable for pulling a propper vacuum, I could allways use it as a vacuum hold down for my cnc router when it is done.

$15 would be the best value vac pump around.

You want a cheap vacuum pump ask my aircon installer. I swear he spent next to nothing for it.

And it looks exactly like a small bicycle or car tyre air pump

No I will not touch auto A/c,s

What were you expecting?
My first vac pump was home made, an electric motor and a pump on a frame with a belt between them, nothing flash but it did the job.
As long as it is rated it doesn't matter what it looks like.
Did he have a name brand drill or a GMC, and would it have made a difference to the holes he drilled?

Why not, surely Toyota have manuals and all the tools required, how hard can it be?
