Purchased: August 2023 - still works GREAT!I kzread.infoUgkxxsUnXhGsSJLim_XnMHyQK0u3XVaW-CGn live in a studio and during the summer it gets scorching hot - really old building with no ac units. I can’t express how EASY it was to install. This unit has been a life savior during the summer and some days during other seasons where it can still be a bit warm at night. In this small place is my friend, a husky, poodle mix and myself. We need AC - lolI don’t use the dehumidifier option - I’m not sure if it will leak in my house, since I did not install the small draining hose that came with it. May look into it late but I don’t worry about much humidity in the apartment. I don’t understand why the negative reviews since all things mentioned, I personally did not find issues with. Definitely worth it!

*Solid, **Fastly.Cool** and gets the job done. For rooms where window-mounted air conditioning is not an option, this works very well. Easy set up, rapid cooling, and great design.*

Your attention to detail was spectacular! Attaching the ground wires first, always Best Practice...I just enjoy seeing technicians doing the best and proper procedures, well done!

​@Artseventy6 you use double 30's

When wrapping a stranded wire under a screw twist the wire counter clock wise before wrapping the wire clock wise under and tighten the screw. This stops the stranded wire from being squashed out from under the screw while being tightened. When using a crescent wrench apply the major pressure against the head of the crescent not on the jaw or bottom of the wrench .

Nice thorough video, makes it all look straightforward and clear. Now back to real life for someone who does not do this for a living. On my indoor unit, not a Mitsubishi, for starters I cannot even find the screws to attach the 4 wires to. The 40 page instruction booklet is amazingly confusing and incomplete, mostly leaving out a lot of things and seeming to assume that you are in the business as an installer. I can hardly believe that the mini split I purchased (Home Depot) is certainly not as easy as installation always appears in these KZread videos. I have many questions, and am still slowly plugging away at it. I still have no idea why a lengthy instruction booklet has to leave so many unanswered questions. Incidentally, I am a fairly experienced person with many tools, and pretty experienced with electrical installations too. But this is my first mini split. I blame most of the problems on the poorly written instruction booklet. This will also require buying a good many more specialized tools for hundreds of dollars.

keep it up with the electrical stuff...its where a lot of guys struggle. Now if only you did supermarket stuff !

a trick for the ground wire is strip it normal length (about 1/2") move down the wire 1/2" further with strippers but ONLY slide the jacket out flush out with the previous stripped portion. so you have 1/2" of stripped wire and the 1/2" past will still have jacket flush to the end of wire itself, the strands stay together, you can twist it tighter and it terminal wraps much easier.

The end of the jacketed MC Cable going to the JMC Connector should be cut about 1/2" exposing the armor. The locking fingers inside the JMC Connector is what holds and makes contact with the armor creating a bond. It is not properly installed if the JMC armor is not properly cut before inserting into the connectors.

Ac best ac its the best quality by american or japan and daikin also

Nice. Nice. I love it.

Decent video, but as an electrician I have a couple of observations: You don't need a red devil with that snap in MC connector. There is a captive one built into the fitting and adding another doesn't allow the cable to fully seat. Second, when wrapping stranded wire around a screw terminal, twist it counterclockwise when looking at the tip and then wrap it clockwise around the terminal. This will allow it to cleanly stay in the loop while you tighten it without the strands spreading. Alternatively, crimp a U or ring connector. Third, when stripping stranded wire go up one AWG in size on your stripper. You risk knicking the outer strands if you don't, causing the same condition that you warned about with your diagonals.

I really appreciate 🙏 thank you

Your videos are thorough but I feel that you are mostly narrating a process that is familiar to you rather than outlining and explaining it for someone who hasn't done it before.

Great videos. Any harm in using a fused disconnect and.. a circuit breaker? I have a 18K BTU unit so 20 amps 20 amp breaker and 20 amp fuses. Also what are your opinions about a surge protective device like the Intermatic AG3000. Again thanks for all the great information, well done.

The only problem that if found with this installation was that you needed to strip back the jacket on you metallic seal tight before installing the cable into your snap in connectors. it is very important to get a direct metal to metal connection on all metal parts of your system. the metal part of your seal tight must be bonded as well.

Thanks for the video. Both L1 and L2 are 110V? Is it 110 V heat pump or 240V?

Good content! One question: looks like you are using 12/2 AWG wire for the 240V input power from circuit breaker. So, there is no need for the neutral wire? like 12/3 wire?

@TheBlindSwordsman

2 жыл бұрын

There isn't a neutral in a 240 volt set up. With 12/2 wire for example both wire get connected in your electrical panel to a 2 pole double breaker, one wire for each. You would need to put black tape on the white wire at the panel indicating that its a hot wire not a neutral as per code. Then your ground wire in the ground bus bar. Hope that answers your question.

Why do you have a single head/zone with two conduits connecting to the condenser? Unless there is some exotic code in your locale, then you run your power AND your control lines into your disconnect and then your conduit to your condenser carries your control lines and your load lines & ground to the condenser? Also when using stranded wire recommended practice is to use the appropriate crimp style connector. These units are very sensitive to voltage fluctuations.....dont forget your surge protector inside your disconnect switch....

I’m doing a mini split install now. I ran 14 gauge wire for my line voltage which is on a dual 20amp breaker. The whip I have has 10 gauge wire inside of it. Is it ok to run that to my line connections on my outdoor unit?

@johncross3065

3 жыл бұрын

I may be a little late on this but here is what I think you’re asking. Yes the # 10 is ok. You can put large wire but never smaller than the over current protection allows. What you need to look at is the 20amp breaker feeding the 14 gauge wire. That is incorrect. The minimum size on a 20 amp breaker is #12. By design the breaker is ment to be the weakest part of the circuit, placing under sized wire changes that and makes the wire the weaker part meaning the wire would fail before the breaker would trip. So protect the unit with the over current device called for on the name plate then size your wire correctlet from there.
