## Questions & Answers

**Q: It says 115v, but does it require a 240v connection for the outside unit? hvac guy asked**
A: This item as described is NOT the item shown--NOT A 115v !! Pay close attention to the item description and on nameplate when rec'd. The item shown has a nameplate on unit for 208-220v which is where the HVAC guy was looking. You should know Chinese products have a diff. (weaker) view of voltage vs. NEC--research this thoroughly before proceeding. The 220v unit (this one as described) only has one white wire--not two-for load, depicting 115 volts which is scary. I used 10-2 AWG b/c of this, but you can get away with 12-2 or even 14-2 (easier to bend and handle ESPECIALLY through conduit and at breaker panel--get and use a fishtail), with 30 amp dipole breaker. Also certain states require GFCI at disconnect box (research this!)--an added feature b/c it may also provide a HOT internal to box outlet (if so, shut off at breaker before all maintenance--unless you need the outlet for adjacent usage). I purchased a 60 amp disconnect w/GFCI--yea, all this was overkill, but I can go up in unit size if I want to later. But seller should be honest and more open about product. Seller no longer responds to and sells these--why they are at a discount.

**Q: How many watts or amps does this use under load?**
A: How many amps will the 9000 BTU use.

**Q: How long is the line set?**
A: 16 ft.

## Customer Reviews

### ⭐⭐⭐⭐⭐ 12KBTU units work well and are quiet and efficient. Heat and cool.
*by J***N on July 17, 2025*

Work great. I have purchased over 4 units and all are working. I use the 115VAC model because I operate my home on solar. Very efficient on power use and QUIET!. Don't waste your money on noisy window mount units. Takes 4-6 hours to install, If you have an AC friend that can vacuum the lines after install, verify no leaks, just open the valves on the compressor unit and it is pre-filled with refrigerant.

### ⭐⭐⭐⭐⭐ Made my man cave very comfortable
*by C***Y on July 31, 2025*

Purchased for my man cave, work very well and real easy to install, a must have

### ⭐⭐⭐⭐⭐ Split unit 115-Volt 20 amp  HAVAC AC/heater.
*by P***E on July 17, 2024*

This was a fantastic buy $$$ cool’s are 500 sqf + room it turbo blow’s fantastic and it is super supper whisper quiet.the ECO mode all so a plus. And it heat the room without ease.!Wife and I have decided to buy one moor unit for the living room it has the feel of being in a #5 ***** Hilton Hotel. It was very EZ to install you need a special fitting for the AC Gauge vacuum pump, which you can also buy on Amazon very EZ to fallow institutions.i did this by my self one handed.i do recommend getting moor Insulation for copper lines and good Insulating tape.lines are all very long so plan out your spot not to have to much line Coiled up behind the outside, AC unit and a place for the condensation line to drain correctly.a good cord less drill to set concrete anchor’s I used RED HEAD’S bot at Home Depot and a Disconnect 30 amp fuse box for the outside connection and a double pole breaker at the panel. Our room had to designated plugs, so the install was very easy after switching out a breaker.it dose not use to hi of AMP’s depending on what you have for power I don’t see a problem putting a Disconnect box and piggybacking off a existing outlet with a GFI or fuse disconnect box to securely protect the AC from any power outages, power, spikes or drops. I did this out of just overly protecting it, I also drilled through the concrete and set a 6 foot ground copper rod grounded that as well to the disconnect box and the circuit. Our home does not come with a ground. It is ground through the conduit so adding that was just a precautionary, it ties into the neutral leg of the panel with some advice from All pro electric in Rancho Cucamonga CA. Master electrician.i give this project a1 out of 10 on a difficulty level of a two.! For do it Self Project .And give the Product a hard, five stars.! #5 ***** wife and I did consider putting in a replacement wall A/C witch cost moor money then then this split unit $400-$600 for the same or Slightly bigger BTU it all so takes way less time to heat and cool then a wall unit and No noise I can’t specify that enough whisper quiet.the the cost of the split unit with shipping charges was Equivalent to our or slightly less $$$ than a window/wall unit, AC and without the ugliness and bulkiness and The noise that a wall or window unit makes of a traditional wall unit.it all so uses less power than a traditional AC unit for a older home without central AC and heat.has a grate Updated Decor and Modernized the room. I can’t thank the company enough it is and dose what it Describes too a T.!!!.
