Since last year I've bought and installed a Senville 9K BTU Leto and a 24K BTU Aura in my home and a Senville 24K BTU Aura in my shop for Cooling and heating. They have Great Customer Service. Bought all the tools for installation and Learned how to install these units on KZbin with channels like yours. Thanks With the 24K in the shop we saved almost 50% of the heating costs over the year before. This coming winter I'll be testing the new 24K in the house..

Hello! First, let me say that I LOVE all of your videos! Second, I used to work as an electrician in mining industries in the 70's. I wanted to mention something about the wires at 10:33. I saw the legend but the way we used to deal with colored wires was to match them to numbers in alphabetical order according to color: Black begins with the letter "B", White -"W" and so on. So, TB 1 = (B) Black TB 2 = (R) Red TB 3 = (W) White Alphabetical order! Never have to remember or write things down! I don't know if this will work for everything in the HVAC industry but thought I would humbly suggest it! Best Wishes and Take Care, Tom

lol - a ground rod is not an effective ground to clear a fault. Need to run the copper wire back to the main panel. nice install and looks awesome. Have any videos that talk about using a ducted minisplit to replace standard ac that sites on top of a furnace?

[@ntsecrets]

Yeah I don’t get that lack of ground. I don’t think that meets code. Should be bonded to ground at the panel.

[@TimJessen-b9v]

The ground rod will not clear a ground fault, and if there is a ground fault,the condenser will be live voltage,and could kill someone who touches it. It needs an equipment ground wire run back to the panel to clear a fault.

[@honemorrison4013]

why would a ground rod at the unit be any different from the ground rod at the panel when it comes to popping the breaker or fuse

[@TimJessen-b9v]

​@@honemorrison4013 the ground rod at the panel is connected to the ungrounded conductor with the system bonding jumper, creating a low resistance path to trip the breaker in case of a ground fault. A ground rod at best has 20 ohms resistance,and a ground fault with only a ground rod will only pass 4 -5amps,,,and not nearly enough to trip the breaker.

The drain is not meant to go that way behind the head unit. There should be a plug on the unit near the hole you made that can be removed and put to the other side. Also if you remove the outer shell of the wall unit you can seal the hole behind the unit and will prevent more dust entering

[@benr.3009]

Thank you again David! I don't now if you all can appreciate the difference in noise level in our house without the window units. We even had a portable 12000 BTU unit upstairs to help the window unit. this split system is game changing! Our little thermostat on the other side of the room matches what the unit says if not one degree colder. And to get rid of those death trap heaters was a bonus as well. we couldn't be happier with it.

[@christophertuten6772]

I have this same unit installed in our 1800 square foot pole barn, and it does a great job at heat and cooling. Worth every penny to upgrade from their base 17 seer model. We had the base model installed first, and it couldn't keep up, so we added the Aura, and now we never use the 17 seer model. The Aura is built like a 3 ton unit, but sold as a 2 ton. The inside unit, and outside units are much bigger than the 17 seer unit. It pulls the same wattage also, so you do get what you pay for.

[@Optimization_Coach]

I love my minisplits/heatpumps. They are far superior to any of my conventional 4 ton units by a long shot

[@sailingwiththegods538]

Where the lines need to be bent I use old 14 wire grounds and wrap them around the piping. I wrap them so they're 1/4" apart and electrical tape the ends to the tubing. It prevents the tubing from kinking. It works well for me. The ground needs to be tied into the house ground somewhere, otherwise it won't clear a fault and trip the breaker, you'll only get overload and dead short protection.

[@Ahmad-Nader]

At 14:57 you seem to wrap the high and low pressure lines together in one insulation covering. Shouldn't these be separated to avoid heat transfer between them?

[@christraudt6730]

master electrician here - i admire your dedication to a high quality install, however the ground rod is next to useless. the purpose of ground rods is to create an equipotential plane with the utility provider and the structure it’s connected to. an equipment grounding conductor is what you were missing, and its job is to carry ground fault current back to the service where the ground and neutral are connected, this creates a complete circuit and allows a breaker to trip in the event of a ground fault. how you have it set up, unfortunately will not clear a ground fault, and the disconnect box and ac condenser will be live (120v) in the event of a ground fault. to rectify this, a ground must be ran to the panel where that electric strip heat breaker is.

[@anticapitalize]

The drill bit flaring tools work well for these mini split connections. There's another video (forgot the source at this point) which compared all of the flaring tools and examined the results under a microscope and it turns out that those old-style flaring tools leave micro-scratches which eventually lead to leaks. The drill flares and the orbital flares performed the best, as I recall. Best practice is use to Nylog Blue regardless of which method you use to help with leak potential on all flared connections.

I should have bought the Aura. I got the Senville Leto and could benefit from the added efficiency of the Aura in the winter. But the Leto still paid for itself in about 2 years, compared to using my oil furnace in Canada where oil is heavily taxed but hydroelectric power is dirt cheap. I have to run the oil furnace about 5 days a year in winter when it drops to like -5C outside, which is not very much oil thankfully. Aura would eliminate the need for the oil furnace altogether. My Leto is 24k, but 28k would have been a better size. I have 9k unit I plan to put in the master suite on solar-battery but honestly the 24k unit heats the whole main floor pretty well on its own, however the cold air does not reach the master suite on hot days in summer (but even in a heat wave our nights are 65F outside)

[@cgutowski471]

You need a true ground wire back to main panel, not to the actual earth. That will not clear a fault and actually kill someone. This is install is a huge liability. Separately you did not do a nitrogen pressure test for leaks. The system works under pressure and a pressure test will proactively find the issues.

Yea that's a huge issue. Clearly there's misunderstanding of what a grounding conductor actually does.

[@peckerpeter2078]

Wouldn’t it be better to Y both sides of the drains so there’s never a drainage problem, heard some rust on inside with only one drain hole used… Also could use pvc for drain with adapter where possible. Corrugated tubing always builds up bacteria, it’s flexible, but definitely not durable and on longer runs that’s definitely not long enough supplied from the factory.

great vid thank you, i gotta do potentially 6-7 of these. What's your thoughts on the nitrogen test? one one hand most company install docs only mention vacuum. (but pioneer on their site does mention pressure testing...just not in the install doc. I also see the point in hey it can check for leaks under pressure, but at the pressure these new refrigerants operate (and that they will likely fail at some point anyways down the road due to that..just common sense) , some say only test at few hundred psi for basic leaks (which i mean is it really a test unless you take it to 475-600 whatever the particular unit runs at) or are you really just risking blowing some nitro past the refrigerant shutoffs. To me if you're not gonna run a test up to 600 or whatever , the question becomes for basic leak checking is a micron test equivalent to a few hundred psi nitro. I also really wonder if you do a full nitro pressure test and it's not in their install docs and they going to blame that when you discover a leak or something.

Did the senville come with shrader core removed or was there a reason you removed it as part of install? I installed a single head DIY pioneer unit using almost the exact same steps but my shrader valve failed to close upon removal of my gauges/vacuum pump. Ended up loosing about 20% of refrigerant. Then had to find a tech that would even touch mini splits to recover and recharge to factory spec (since you can't really check charge on these). Had I used a procedure like you did (including the core isolation/removal tool), it would have saved me the cost of tech and recharge.

They have no built in em heat. Getting a heat pump mini split, it gets anywhere under 35 degrees is a waste of money if you want to heat with it. Your condenser outside will just freeze up, making the unit throw an error code an stop working. They are great for cooling. Garbage for heating anywhere it gets really cold. Which is why you dont see heat pump units up north. Unless they are duel fuels using a gas furnace as em heat instead of electric heat

[@cgutowski471]

Disagree. I have a Senville 24k Aura installed in a high elevation cabin. It gets to below -10°F and still heated efficiently this past winter. Power usage was 1/2 of what the electric baseboards have been in previous years. The Aura has a pan heater to remove any ice buildup around the bottom of condensing unit. Works great.

[@planesandbikes7353]

The Leto range will struggle below freezing, but the Aura can handle really cold temps and keep heating with OK efficiency. Now if you mean actually really cold - like -30C or below 0F like it can get on the northern prairies, then you probably are a candidate for a dual fuel central HVAC or just have your old gas/electric/oil furnace for backup to the ductless, or just some baseboard heaters for those ultra cold nights.

[@sailingwiththegods538]

I live in NY and use my 5 year old Aura all winter and it heats perfectly fine down to 0F, and falls off below that. The condensers don't freeze up, when the coils get iced over the unit runs the cooling cycle for a minute or two to force heat into the condenser to melt the ice, and a pan heater. It only freezes up around 20-30f, when it gets below 20 it doesn't freeze up much. There are A LOT of mini splits being used up north, I don't know where you heard they're not. We do need supplemental heat when it gets below zero but that's not a surprise. I went from 6 cords of firewood down to 1 and the mini split costs less to heat compared to firewood too.
