Simplified Product Title: CSRU2 Compressor Saver Hard Start Capacitor Kit for 3.5 to 5 Ton Air Conditioners

The Long Term ZRUB hard start kit is applicable to 3-1/2-4-5 ton AC units. It includes 1 ZRUB hard start capacitor kit, 1 cable tie, and 2 screws. UL certified and replaceable, this CSR-U2 Hard Start Capacitor Kit is designed for HVAC Hard Start Capacitor 3.5-4-5 Tons. It is made to precisely fit most AC brands.

The 5-2-1 method, recognized by major compressor manufacturers, provides a safer and easier installation process. There are only 3 color-coded wires that need to be connected. The Black wire connects to the Common side of the compressor, the Striped wire connects to the Start winding, and the Red wire connects to the Run winding. This simple 5,2,1 connection (Common, Start, Run) ensures a straightforward installation.

The ZRUB compressor saver reduces the time required for compressor start-up by approximately 30-50%. The CSR-U2 Starting Capacitor utilizes a powerful multilayer starting capacitor and smart switches to provide the compressor with the necessary boost to start faster, more reliably, and consume less power.

The Long Term ZRUA hard start kit meets or exceeds all manufacturer specifications, is made of durable high-quality materials, and has been thoroughly tested by the manufacturer. Designed as a tool for professional service technicians, this kit is a reliable solution. It's important to note that if you notice the compressor economizer expanding during use, this is due to extended use, high external temperatures, and the production of gas inside, rather than an indication of an explosion.

This compressor hard start kit delivers a higher starting torque for the compressors. It also increases the energy efficiency of air conditioning and refrigeration systems by as much as 98%, and extends the service life of compressors and other electrical components related to air conditioning systems.

In summary, the Long Term ZRUB and ZRUA hard start kits offer perfect compatibility with 3-1/2-4-5 ton AC units, easy installation through the recognized 5-2-1 method, and the ability to fix start-up problems and enhance system performance. These high-quality, durable kits are designed for professional use and provide a reliable solution for improving the efficiency and longevity of air conditioning and refrigeration systems.
