The 5-2-1 Compressor Saver
Starting up is the hardest time in the life of any type of electrical equipment. Ever notice that light bulbs almost always burn out when you first turn them on and not while they are on? This is due to the huge current that rushes in when a switch is thrown and power is first applied.
Your air conditioner uses anywhere from 5 to 10 times more power on start-up than it does while running. With this burst of power comes a surge of heat that accompanies the electrical current. This heat damages the compressor, the terminals, the windings and run capacitor – all vital components of your air conditioner.
The 5-2-1 Compressor Saver® protects these components by significantly reducing the amount of time it takes for your compressor to start – in some cases up to 50%. This means your air conditioner and compressor will bear ½ the stress, strain and heat each and every time it starts. Considering that your air conditioner may start up more than 6,000 times in a single cooling season, the positive impact that the 5-2-1 Compressor Saver® has on your air conditioner is significant.
Before you replace your air conditioner, try adding a 5-2-1 Compressor Saver®. The 5-2-1 Compressor Saver® might save you from having to outlay thousands of dollars to buy a new air conditioner or compressor. At a fraction of the cost, installing the 5-2-1 Compressor Saver® is a wise investment.

Techincal Diagram
1) Disconnect all sources of power to the unit. Note that there may be more than one.
2) Locate and remove the electrical service access door or panel.
3) Mount the 5-2-1 Kit potential relay and start capacitor in a suitable location within the electrical box. The potential relay should be mounted with the mounting tab up. The capacitor should be mounted with the terminals up. Take care to mount the components so that all non-insulated live terminals are at least 1/2" away from all metal or electrical conducting parts or components. Mount in a location that will prevent water from coming in contact with the non-insulated live contacts.
NOTE – The 5-2-1Compressor Saver® has been pre-wired for your convenience. There are only 3 color coded wires which need to be connected. The Black wire will be connected to the Common side of the compressor. The Striped wire will be connected to the Start winding of the compressor and the Red wire will be connected to the Run winding of the compressor.
Remember – 5, 2, 1, = Common, Start, Run. Proceed as follows:
"5" Common - Connect the loose end of the Black wire to T1 of the contactor. Check to see that the Common "C" terminal of the compressor also connects to T1. In most cases you will find a Black wire coming from the Common "C" terminal of the compressor.
"2" Start - Connect the loose end of the Striped wire to the Start winding side of the run capacitor. The Start winding side of the run capacitor is always marked "HERM". The Start winding side of the run capacitor can also be verified by following the yellow or orange or blue wire (in most cases) from the compressor "S" terminal to the Start winding side of the run capacitor.
"1" Run- Connect the loose end of the Red wire to the Run winding side of the compressor. The Run winding is connected to T2 of the contactor as well as the common side of the run capacitor which is usually marked with a "C" or "=". The Run winding can be identified in most cases by a Red wire coming from the R terminal on the compressor. The Red wire from the 5-2-1 start kit is normally connected at the "C" or "=" terminal on the run capacitor, but can also be connected to T2 of the contactor. See the illustration below.
