FEW INSTALLATION RELATED FAQ's

Can I put the unit in a Basement, Attic, Garage, Office building?
Absolutely. The Amcoraire DUO can be easily installed anywhere. In all cases, the drain pipe is pitched to the outside. In some cases, a condensate pump may be required.

Instead of installing compressor on the ground or backyard, can I install the compressor on the roof? Can the connection lines go up to the roof, instead going down?
Absolutely Yes. You can install the compressor on the roof or on the ground, would not make any difference. This is why mini splits are so convinient for installations. Check the installation diagram below.

What is the operating range of the unit?
The unit is rated to work between 62-90°F.

What happens if the unit requires servicing after the 1 year NO HASSLE warranty period?
You still have FIVE year compressor Warranty and 3 Years on ALL PARTS. All Amcoraire air DUO conditioning units can be serviced and repaired by any professional air conditioning company. Most likely you won't need any servicing if properly installed. We have one of the best "Toshiba Compressor" in our mini splits compared to any "B" grade compressors which some company's sell.

If I decide to install it myself, will I need vacuums to charge up the lines. I assume that the lines need to be charged up with refrigerant and that it has to be setup by a qualified air conditioning technician correct?

YES. YOU WILL NEED A SET OF GAUGES FOR R410A AND A VACUUM OR JUST CONTACT A HVAC QUALIFIED SERVICE TECH AND PAY BETWEEN $150-$200 FOR A FINAL SET-UP AFTER YOU INSTALL THE UNIT.

Is this something that I could install myself?
YES AND NO. If you are not sure what you are doing, you will end up installing it incorrectly and thereby will loose the warranty.

Is outside unit a metal or a plastic case?
Metal case as plastic vibrates and make a buzz. It is made of Galvanized enamel coated metal.

ALL SPLIT CONDENSERS ARE 100% WEATHERPROOF.
RAIN, SUN AND SNOW WON'T BOTHER.

SHOULD THE CONDENSER BE ON A FLAT SURFACE OUTSIDE? IS IT FINE EVEN IF IT IS ON THE GRASS?
IT IS ALWAYS RECOMMENDED FOR THE CONDENSER TO BE ON A PATIO BLOCK OR BRICK TO RAISE IT A FEW INCHES BUT IT IS WATERPROOF.

The distance between my indoor and the outdoor unit will be more than 25 ft. Kingersons package provides 25 ft:-
1. Is it ok to extend it upto 90 ft? YES IT IS.
2. What kind of pipe extentions or what quality do I need? Either solder silver the new copper lines on or flair with a coupling.
3. Where will I get this quality from? home depot? YES, Home depot or any plumbing supply store.

Where on the wall should I install the indoor unit and How high?
4" FROM THE TOP OF THE AIR HANDLER INSIDE AND CEILING IS REQUIRED.

What if I want the indoor unit installed at a 6 ft high?
IF YOU HAVE NO CHOICE AND WANT TO MOUNT IT LOWER EFFICINECY WILL BE LOW AND MAY NOT COOL WELL.
COLD AIR FALLS AND WARM AIR RISES. So higher the indoor unit, better it will cool the room.

Can I install indoor unit 2 ft above the floor?
Not recommended but may work ok though. FLOOR MOUNT IS NOT RECOMMENDED IN MINI SPLITS.

I don't want to install the outdoor unit in my backyard or on my roof. What if I want the outdoor unit installed on the outside wall instead?
Wall bracket for condenser is an option and in stock only for $45 plus $15 shipping. Great value.

Does mini split has air purification capabilities? Air filters?
Yes. Cold catalyst air filter.

Can the outdoor unit be in the straight line with indoor unit, or it always should be above or below the indoor unit level?
Straight betwen condenser and air handler line is ok .

I can't directly run the expel tube down to a drain. I may have to actually pump it back up 10 feet to the roof? What are the options to the direct gravity method for moisture expel?
You can add more drain pipe to reach the ground or you can put a
condensate pump and pump it anywhere you want to.

What size breaker and gauge wire would you suggest?

The 24,000 btu unit is rated for a 20 amp breaker, which requires 12 gauge wire at 25’ (distance between outdoor unit and the breaker)

The 18,000 btu unit is rated for a 15 amp breaker, which requires 14 gauge wire at 25’ (distance between outdoor unit and the breaker)

The 12,000 btu unit is rated for a 20 amp breaker, which requires 12 gauge wire at 25’ (distance between outdoor unit and the breaker)

The 9,000 btu unit is rated for a 15 amp breaker, which requires 14 gauge wire at 25’ (distance between outdoor unit and the breaker)

Is there only one copper tube or two?
2 copper lines.

Is the drain line a flexible tube or solid pvc?
It is Flexible

Distance from inside air handler to consenser is 30'. How would I add to the standard 25' length that is included? Can I get a 5' length with flared ends and a coupling?
Yes you can buy the extra flared and coupling from any plumbing store or home depot.

How would you suggest I make 90 degree turns in copper tube?
You can do it slowly with your two hands and a large radius to make the 90.

Does Power only run to Main Compresssor Unit and the Fan piggy Backs off of the main Compressor? Or does power need to be run to both Units Individualy?
POWER ONLY TO CONDENSER OUTSIDE UNIT THAN IT FEEDS TO THE
INSIDE UNIT.

Do your mini-split units have the electric heat strips or do they have heat pumps.

They are Heat pumps. No heat strip. But unlike many other heat pumps, they run down to 17 deg F.

I will be running the pipes high 30 feet. Is that much elevation ok?
20 FEET MAX IS OK. YOU MAY BE ABLE TO GO 25' UP AS WELL BUT IT MAYBE A PROBLEM.

SOME MORE PICTURES - Below is just an illustration of one model, with different pictures, it should not be considered as a complete installation guide.

	First check the install kit. Refrigerant lineset and wire harness are your main components
	Other Miscellanous items
	Your compressor
	Locate the wire with black connector from inside the indoor unit, this is where one end of your defrost wire will be connected.
	The defrost wire is the grey wire that comes in the package and is shown connected on the right. The other grey tube is your drain pipe coming out of the indoor unit. The white insulation has copper tubings inside.
	One more look at everything.
	Once the prep work is done, you can install the indoor unit wall bracket on the wall. In this case we chose to go out from the right for the connections, so we made a 3 inch hole in the wall as shown in the pciture. You can make this hole on the left also if you would like.
	As you can see the indoor unit is installed on the wall. The lineset with insulation, defrost wire, electrical wires and drain pipe are all smoothly pushed out through the hole (shown above). Please remember the indoor unit should be installed horizontally in such a way that the water can easily drain out through the pipe using gravity. We have seen people install it without using the level guide, resulting in tilted installation which finally will result in water leak in house.
	This is the outside view, showing everything as per above.
	This is where the compressor will be placed, since we had an existing concrete pad already. You can go as far as you want with your compressor (50 ft to 100 ft depending upon the model you buy) You can install the compressor on the roof also if you would like.
	We opened the insulation a bit to expose the copper lines to make the connections.
	This shows how the final connection was made and tied together.
	Finally compressor was placed in its position.
	At this point the electrician finished his job by connecting the compressor to the circuit breaker and connecting the electrical wire coming from inside unit to the compressor. If your compressor will be closer than this, it is important to remember that lineset should be minimum 10 ft long to avoid any damage to the compressor. We have seen people place compressor right behind the indoor unit (outside) and then cut the lines to about 7 ft only, resulting in compressor issues. In short you can keep the compressor close to indoor unit, but you can roll the line set to make it longer than 10 ft minimum.
	The adapter on the left is newer R410A adapter, if your contractor don't have one, you can click here to buy one. By now, the HVAC contractor was ready with the tools. He was here on an hourly basis to perform 4 important steps (normally 1-2 hour job max): 1. Connect the lines. 2. Vaccumming the lines, to make sure NO moisture is left in the copper tubings. 3. Checking for the leaks, to ensure the refrigerant won't leak out in case the copper lines had leaks. 4. Finally he will release the refrigerant and make final tests.
	At this point, he is connecting the adapter to connect his tools.
	Making connections.
	Connections made to finally do the above tests.
	Now vacuuming the lines
	Checking for the leaks
	almost done .....
	This is the liquid he sprayed on the lines to make sure there were no leaks.
	Once done, the HVAC contractor can disconnect his tools and use the bolt to secure the compressor to the concrete pad and place rubber pads underneath to avoid vibration. This will be your final layout. You can cover the copper line with anything to give it a final touch. See some examples below.
	Various examples of installed compressor. On the roof, on concrete pads, on wall bracket below the window, on the ground.
