@hvacraustralia you have the part number for the new fan motor??

No worries mate. Yes, you can remove the fan motor without disconnecting the copper pipe work. I don’t have the part number sorry mate.

I can’t remember 100% what I said, this was filmed around 5 months ago. I probably meant to say, when they’re that impacted that the collapse inwards it’s time to replace them. We did clean them to get them through.

Thanks mate, glad you enjoyed it. This particular job was quoted by another tech. I did confirm the oil return lines weren’t plugged after replacing the compressor. If I ever need to replace a compressor in a Daikin I’ll always replace the oil line too.

I started doing it a few years back because I had enough of all those annoying cuts you get. Initially it was weird, but now it’s feels weird without them.

I was actually inspired to wear gloves after seeing you wearing them. Initially didn't like the loss of dexterity but after a while it's not noticeable. It's a game changer no more cuts from coils fins and sharp bits of metal, with the added benefit of not having dry crack skin in the winter months.

It’s weird to start off with for sure, but you very quickly get used to it. I don’t notice they’re on anymore.

@@hvacraustraliaI bet the misso would lol

Thanks mate.

Yeah, it’s unfortunately very common.

I didn’t realise until somebody mentioned something, but this video and my latest one uploaded as SD. I film everything in 4K but it had to do with an upload setting that was determined by my wifi quality. I’ve adjusted that now so from next week HD and 4K will be available.

@hvacraustralia cheers legend

Turning vanes help turbulence to get you a more stable static pressure down the duct but its still shite. That cowling not being there in the first place is a joke, one of the first questions we got asked in mitsi course 😂

😂 it’s fucked no matter which way to look at it. My last suggestion was to relocate the YKB and P Series units outside, turn the PUHY in the corner to face the wall with a similar set up to the other two and cut out that acoustics crap. Or remove the roof 😂

It would help for sire. If my static reading was closer to 60Pa we could have suggested it, but I don’t think vanes would drop it that much unfortunately.

Sorry mate, I don’t believe so currently. Are you based in Aus?

Yeah, 100% adding the cowl increased the airflow. My thought process for removing it after was that the units will decrease the frequency of the compressor to hit their target evap and condensing temps and have a lot of safety’s in place to protect the compressor. The fan motor doesn’t have those safety’s and if I left the cowl on with a static of 130Pa I didn’t know how long before the fan motor would be damaged pushing against that much of a restriction. The capacity of the units won’t be 100% because the unit won’t be able to ramp up the compressor but they shouldn’t lose another fan motor this way. This place isn’t quick on making decisions.

I did measure at multiple points the first time around without the cowl and there was a marginal difference in static measurements. From the reading I’ve done on this it does appear measuring either side of the fan within a meter or so is the correct spot. Regardless, I doubt any spot I measured would have given me a reading under 60Pa 😂

I take me previous comment back, you’re right. I should have measured further down the duct for a more accurate average reading. Cheers.

It’s brilliant 😂 not straight up as the roof ridge is directly above it, but going out through the roof was my first suggestion to them.

I’m done with this job 😂

Thanks mate, glad you’re enjoying the videos. Good luck with your apprenticeship. It’s a great trade.

Hey mate. Yes, that’s normal. You need to purchase the copper separately.

@@hvacraustralia Thank You!

Mitsubishi Electric’s manual says 1h for their YNW HR units. In the end, I do what I can with what time I’m given.

😂 it is like that sometimes. I usually just do some quick confirmation now wherever I go to something I didn’t diagnose at the start.

Thanks mate.

"It's draughty!" *Turns switch off* 🤣

No one could tell me why it was off either 😂

They’re great fun to work on.

Ah that’s good to know! Thanks for sharing that mate.

Thanks for brining this up. I film everything on the 4K setting but I’ve now realised there was a setting that determines the quality of the upload depending on my wifi connection. I’ve change this now. Annoyingly the next video will also be SD but after that HD and 4K will be back. Cheers mate.

100%. The hard work at the start absolutely makes it worth it. A lot of fun to work on.

Thanks mate. Glad you’re enjoying it 🤙

Thanks mate.

Thanks mate. Appreciate it.

Mine too mate! And I really like you. FVMA is my favourite too. I am on your page too! - Riley

@ yep Good to see another old girl go again

@@GeneralAvitation By girl do you mean me? - Riley

or the AC?

@@suezq74 no the ac

That’s handy to know! Thanks for the tip mate. Appreciate it.

Thanks mate, appreciate it.

come off it you slag. you struggle to connect your gauges to the unit, i have seen you

Hey mate. Glad you’re enjoying the videos. Most places do have some form of roof access but I do also carry around an extension ladder just in case.

Oh man, I feel you on that one. Issues like that can drive you mad 😂 We’re Temperzone able to rectify the issue?

I didn’t notice any oil but it will be something I’ll look out for. Cheers.

This is my thought too. This entire site has power issues, but this is the only unit going through boards. Once they don’t need to isolate the unit to carry out testing and are no longer using a generator it will be interesting to see if the issues persists .

Insane tip

That’s a great tip! I’ve never thought of that. So simple. Thanks mate.

How would you determine the health of the fan motor by doing this ? Thanks

The UC8 board sends a 0-10VDC to the fan board which in turns sends AC power to the fan motor. If you have a fault control UC8 board you could send 9VDC to the fan board to get the fan to run, test amps, listen to bearings etc.

It’s an insane thing for Daikin to do 😂 good luck to them

Thanks mate. Glad you’re enjoying the videos. I have an email linked to the page. Everyone is free to contact me there 🤙

Using my phone, but I have it set to 4K. Surprising how well it turns out.

Thanks mate.

100%

Yeah. VRF is weird... So intelligent and so dumb at the same time 😂

Mitsubishi is my preference to work on.

By the way last month we came across a place that had 1st gen VRV running on R22! 20+ years installation

Thanks mate. It’s always nice to hear where people are watching! I haven’t seen a VRV1! Hopefully one day 🤞
