My group was limited to three people. It weighs 5 tons and is simple to set up. I'd try it myself if I had your system, but I'm not sure how familiar you are with circuits, so I wouldn't recommend it to you. Sorry! br>Toll-free numbers can be found on many of the suppliers' websites. They might be able to provide you with additional or better information. Playing with 220 AC is not a good idea. It will cause you pain.
There is no such thing as a back-up plan. If the relay coil burns out, the cap in line between the Herm and Common will not be switched. I wouldn't be concerned; they last a long time, and my LRA locked rotor amps dropped from 84 to 52, making it a compressor saver.
It's rated for 400 volts, and the relay kicks in at 40 volts, so you should be fine. But I'm not sure what you're going to do with it; I've never heard of a 120 AC before. Keep in mind that the starter capacitor's job is to create the proper magnetic field for the compressor to operate in. It's not like there's anything to lose by giving it a shot.
This type of component is built into the Trane equipment if it's a new Trane unit. This is a good investment if the unit is older. It works.

I'd like to clear up some major areas of misunderstanding and confusion in this regard. In addition, I'd like to discuss some safety concerns to ensure that those attempting a DIY installation do not receive a nasty zap or worse. I'm a big believer in do-it-yourself and saving money, but I believe in saving lives even more. I couldn't make recommendations that I believed put people in danger in good conscience. br>br>However, it is entirely possible to do this correctly; however, exercise caution when working with high voltage and become thoroughly acquainted with the procedure before making any changes. Hopefully, some of the information provided below will assist you in doing so. Above all: br>br> Do not attempt this procedure without an AC clamp meter, preferably one with a 600VAC rating and probe plug-ins for measuring capacitor capacitance. This is a non-negotiable. It's also a good idea to double-check that what you've done isn't wreaking havoc on your air conditioner and that it's working properly. Amazon has a variety of low-cost off-brand options ranging in price from $20 to $100. Electricians and professionals have given this product a high rating of $25. For $25, it makes no sense to risk a very expensive air conditioner and a priceless human life. br>br>Now that I've given that speech, let me clarify a few things: 1. br>br> A start cap is not required for a scroll compressor, according to some HVAC technicians. While this may be true in an ideal world, any compressor will benefit in a practical real-world application. 2. br>br>1. br>br>br>br>br>br It is critical to have a POTENTIAL relay. Other timer relays will not work as they should. 3. br>br>4. br>br>5. br>br>6. The presence of a dual capacitor in your AC handler does not imply the presence of a start capacitor. Likely; This capacitor serves as both a fan and a motor. 4. br>br> The utility of a start capacitor, as well as its size, is indicated on most compressor data sheets (including the Bristol compressors I own). The reason they aren't found in most modern air conditioners is cost: a high microfarad 370VAC cap and potential relay isn't cheap, and it isn't always required for operation. However, having one can help a compressor last longer and work more efficiently. This isn't something you should do if your air conditioner is on its last legs--it's something you should do all the time. Install it PRIOR to experiencing any issues. 5. br>br> It's a bit of a misnomer to call it a hard start. The main goal of this device is to reduce current draw and thus wear on your system when it starts up. It's not so much a "hard start" as it is a "smoother start. " 6. br>br>br>br>br>br>br>br>br> Hard starts have the added benefit of reducing sag on appliances or lighting near the breaker panel where your AC Handler is located. If your lights dim anywhere in the house when the air conditioner kicks on, installing the hard start will most likely solve the problem. br>br>7. If you don't understand electricity, don't know how to use a multimeter, or don't have a clamp meter to test the kit's functionality, don't use it. Attempting to install yourself is not a good idea. By botching the installation, you can cause a lot of costly and frustrating damage. A professional installation should take no more than 30 minutes. Again, you have no business doing this on your own if you can't verify the benefits. If you absolutely must, 100% have a clamp meter and exercise extreme caution and inform yourself by watching online videos of installs and absolutely have a clamp meter and exercise extreme caution. 8. br>br>br>br>br>br>br>br>br> If your unit has been in service for a while, you should probably replace the fan and motor at the same time, as motor run caps require a fine tolerance, and after extended use in high heat environments, this capacitance level will likely change, putting undue stress on the motors regardless of whether or not a hard start kit is installed. Genteq (GE) is my personal favorite because their devices go through a rigorous testing process and are UL listed for long-term stability. NEVER EVER EVER EVER EVER EVER EVER EVER EVER EVER EVER The motor is UL listed and comes from China! You're setting yourself up for failure. The following would be my criteria: The voltage should be at least 370V AC (NOT DC!). ), must be within the specified run tolerance or better, and must be EI- 456- A compliant with a reliability rating of 60,000 hours. All of the Genteqs were ideal. All of the questionable off-brand options were around $8, while my Genteq was $25 shipped. It's not worth $17 to risk your entire air conditioning system. This is not an area where you should be trying to save money. 9. br>br> Determine the size of your AC handler using the method below, and then size up a little (in this case, I had a 3 ton AC and used this ton hard start instead of the 2-ton hard start). Start with 3 tons of force. Remember- The number to remember is 12,000 BTUs or simply 12, which is equal to 1 (one) ton of AC. br>br>The number to remember is 12,000 BTUs or simply 12. As a result, 18,000 equals 1. 5 tons equals 24,000 tons, and so forth. br>br>On the compressor, look for the model number (which is stamped on the actual side of the compressor). To do so, you'll need to take off the cover from your AC handler. There should be a number that is 12 times divisible. For residential air conditioning units, it should start at 18 and not exceed 60. 1 plus 18 equals A cooling capacity of 5 tons and 60 tons is equal to a cooling capacity of 5 tons. If you're not sure, contact the manufacturer or look for a data sheet for your model number on their website. It's not difficult, and I've discovered that most manufacturers' customer service responds to requests for information fairly quickly. 10. br>br> If you forget something, write down everything on the compressor plate so you don't have to go through the trouble of turning everything off and unscrewing the cover again. Before you disassemble anything, document your work and take pictures; this will come in handy later if there is a problem. 11. br>br> When looking for the tonnage of your air conditioner, you should also look for the compressor's run capacitor value, which is usually expressed in "uF" (microfarad). It must be followed by a percentage deviation that is within acceptable bounds. 12. br>br> Once you have the listed values, check to see if your run cap(s) is still within the required specification. Even if it is, it's a good idea to find a backup while the information is still fresh in your mind. Having the right one on hand for a rainy day is preferable to scrambling to find a replacement locally on short notice. br>br>Note: DO NOT try to measure the capacitor without first discharging it with an insulated screwdriver or something similar. If you're still not convinced, watch some videos of this technique in action. br>br>13. Replace the run and start caps with new ones. If you're doing a dual run, double-check that you have the right terminals. Then, as directed by the hard start kit, follow the instructions. They're made to be simple and eliminate a lot of the guesswork from the hookup process. If you have any doubts, pay particular attention to the hookup arrangement: 5- Come to a halt, take pictures, and email or call 1 and inquire about it. br>br>Make certain that both the capacitors and the potential relay are securely mounted. In no case should they be left unattended. Fortunately, there are 5- 1 includes a good relay screw as well as a cap zip tie. If at all possible, I'd go above and beyond: Any unintentional movement could result in a short and result in a catastrophe. br>br>14. br>br> When putting everything back together, make sure the AC panels are properly adhered to each other and that they fit snugly with screws in all of the required places. If you don't do it right, the AC will probably start buzzing more. This could give you the impression that there was an issue with the installation when, in fact, it's just poor vibration control. Look into compressor covers and vibration feet if you want to reduce AC noise even more. After all of this, you should have an air conditioner that lasts much longer, is more environmentally friendly, costs less on your electricity bill, reduces wear on other household appliances, and solves many cases of dimming lights (that are in sync with the AC turn-on). on), and you'll be able to run more quietly without the loud "thump and buzz" you're used to. br>br>That's a great deal for the Hard Start Kit, a Genteq Dual Run Capacitor, and an AC Clamp Meter for under $100 delivered. br>br>I hope this information is useful, and above all, stay safe! 240 volts AC is no laughing matter! Do not detonate a bomb or set fire to your home! The cost of some professional advice is well worth the cost of avoiding these potential disasters. At the very least, enlist the help of a capable friend who has handled similar situations before: Working with only high-voltage electricity is not a good idea.
However, take note! When wiring this up, pay close attention! Again, PAY ATTENTION and, if you're unsure which is which, get an electrician to do it for you! The instructions associate the T1 side of the A/C start relay with the Common side, but T2 is the common side on my Trane unit. br>Apart from that, it was a breeze to set up - It took ten minutes total, five of which were spent securing the components to the air conditioning chassis. This was recommended by the air conditioning company for $270 (parts and labor). You can save money by doing it yourself.
5 ton. When the compressor kicks on, the house lights dim a little, so I got one of these kits (admittedly, I have all LED in the house, so it's possible they're just more susceptible to voltage dips). br>br>It took me all of 5 minutes to put it together, with the majority of that time spent double-checking the capacitor wiring (mine were color-coded to a tee, but it's better to be safe than sorry). The compressor inrush was reduced by 113 percent thanks to the kit. 4 to 88. 1 amps! A total of 103 LRA can be handled by the system. It uses about 14 amps while running, but the kit has no effect on that - Just to give you an idea of how much current it takes to start, and it also seemed less violent, but I'm not usually standing next to the unit when it turns on. br>br>We'll see about durability and light dimming now that our AC season is over, but the kit does exactly what it should.
It accomplishes the task at hand. For $ 270, my air conditioning technician tried to sell me one. 00, but I memorized the name and model while he was showing it to me, then went in and placed an order.
Air conditioners with capacities of 5 and 4 tons. I was attempting to reduce the inrush current so that my portable generator could power my air conditioners. These worked perfectly with my Duromax 13000EH. A maximum of 51 amps can be handled by the generator. So, after you've completed the 5-step process, I give it a hard start by turning on the main AC first, then the secondary. After they're both up and running, I simply turn on everything else. Refrigerator, freezer, garage door, television, lights, internet, fans, and anything else Iffy, if I needed to use the dryer, I could probably do so because the amperage is down to 19 Amps after these guys have finished. br>br>I love this unit and would buy it again if I didn't already have two, one for each of my air conditioners. The other AC 3 is, just in case you didn't notice. This reduced the 5ton's amp draw from 77 to 32 in rush amps.
Simply turn off the power and discharge the capacitors to complete the installation. There's no need to hire an expensive AC technician who will try to upsell you on everything. It will start more easily and run more quietly. This product will satisfy you, and it is less expensive than an air conditioning supply company. I have an air conditioning license, which I purchased for $48 from a supply store. It was $44 on Amazon when I bought it for my son. That's a deal you can't pass up.
My AC repairman advised me to purchase and install this because my second system would most likely fail the same way as my first. He told me that installing it would cost $200, but that I could save money by purchasing it on Amazon. br>I have a Lennox system with color-coded wires, so no guessing and a lot of YouTube videos later, I couldn't be happier.
