Where’s the full video?

Its just like flares. If done right, press fittings dont leak. Not proper deburring and they will leak.

We have a Vrf heat recovery system with the RLS press fittings 5 years ago the factory welds on the FC are leaking all the press fittings have been great, Its all installation practices,

I just can’t bring myself to except B press. I’ve tried but have seen more failures than success story’s . I mean for cleanliness of the system sure it’s great but it’s not that hard to purge during the brazing. And then there is the constant temperature cycling of the pipe work. That’s surely the unknown factor when you hear the comparison between b press water and b press fridge. In regards to the flow restriction I’m thinking not a concern, maybe the chance for noise from the gas flow but time will tell.

Mate if you and the family ever decide to move to Brisbane feel free to reach out. My company pays the highest and will take you on any day of the week.

Mate, I still can't get myself over the line with press fittings (just yet). Enjoyed the video, nice to see your project there from start to finish. #betterhvac

Why didnt you just lift it off and take it out side?

my high school was retrofitted with temperzone Air Conditioning and from what I’ve seen it’s been nothing but problems

What is a 'Branch Box'? Is that another term for the indoor unit of the aircon?

Id say that crimp leaked under temperature and crimping straight onto the branch box that close is a no no need to weld hard drawn tails off the end

I'm not a fan of crimped fittings on AC pipework, brazing, then maybe compression.

so curious about the actual life cycle of press fittings....one side of me is positive because it saves time...other side hoping i will have retired by the time they all start failing🤣

Maybe the O-Ring in the Fitting was not the right one for refrigerant. Here in Germany there are M-Press fittings (brand is Conex Banninger, but with HNBR O-rings for all sorts of Refrigerants.

How about doing a video of the evaporator half? In particular, how you access the filters in the ceiling space.

Could use a clean too..

Those intermittent faults are a bastard

Where did you get those extra long leads from mate? Look very handy.

Your video needs lots of work to make it usable and understandable for someone whos never done the job before

Good job mate

Love the thoroughness!

Have you always tested for shorts to earth just in continuity mode? As a sparky we always use a megger at 250 or 500v for this sort of test, perhaps a multimeter like a fluke 1507 or 1577 would be great for the everyday usage like this without having to get a separate meter? Just a thought cheers

Interesting they're still running overloads on all those. Looks like they've done a VFD retrofit at some point and left them in. I suppose it doesn't really matter but I try to take them out when drives go in, lets the VFD do the protection so any faults will just show up on the drive rather than killing power to it. Interesting find! Any reason you go for the ABB switchgear? Schneider stuff seems to be smaller from experience and looks a bit nicer too.

Nice job Did you evacuate the system all night? Is that what i heard?

Do you have any issues testing high DCV on that fieldpiece meter? Looking at getting one for myself and wondered. I had an old fieldpiece meter and it's range wasn't high enough when testing DCV between inverter and control PCB's

Thanks for sharing the educational content, very helpful for guys getting into the ductless game

Gun! Now quote them some condenser cleans😉

Will the indoor sensor cause the compressor ramp down? Thanks

Had one yesterday going into UO (loss of charge) fault not on the controller but In the Bluetooth checker and yeah had the same thing the suction temp was reading 24degrees but my Testo clamp was 4degrees. I always carry spare sensor kit in my ute now

I’d have put the sealant higher up.

Awesome video mate, can be difficult aligning the adjustable pulleys as the outside edge in comparison to true centre changes when the pulley diameter is adjusted.

Love this video format mate with all the little problems! Would love to get into AC/VRV stuff on the side

What!!!! 😂😂 Someone forgot to do their homework

Beauty!

Typical ceiling mounted noise 🤷

Nice video mate!

Do you have in Australia new mitsubishi package unit ?

Hello, I have just watched the training video, very well done. You have a command window on your laptop screen at minute 11:00 with which you can “command” indoor units. which version of the software are you using? many thanks in advance, greetings Simon

why is the condenser frosting over? it should be the evap.

Confused to how a block strainer will cause a sight glass to run like a river?

😮😮😂😂😂😂😂😂😂… board not working, no defrost?

What is electric voltage in Australia 240 or 110 ?

Fkn tank

And they say flood back is bad for compressors I call bullshit

57 micron owsome 👍🏻

Have you tried using a string line across the face of the pulleys to align them? Nice video.

1:20 don’t those isolators lever up from the centre core for locks? I believe some similar makes like that do. Other than my two cents, good upload!

11:14 I feel your pain mate.

Opening the suction drags the oil out of the conpressor and liquid will boil off before gwtting back to the conpressor that way

Wow just wow! Thats mounted on timber
