FAQ:
Q: Is the csr-u2 kit the correct one for my Daikin compressor?
A: The CSR-U2 kit is the correct one for our Daikin 4 ton unit. The installation was straightforward, as shown in videos and also in the wiring schematic for the compressor. Once installed, the difference was immediately noticeable. The compressor started much more quietly, and everything was working fine. Less than two days later]
Q: Is the csr-u2 kit worth the cost?
A: Well worth the modest cost and hassle in mounting it. The CSR-U2 kit is the correct one for our Daikin 4 ton unit. The installation was straightforward, as shown in videos and also in the wiring schematic for the compressor. Once installed, the difference was immediately noticeable.
Q: How does the 5-2-1 compressor Saver® work?
A: 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.
Q: Do I need a start capacitor with a dual capacitor?
A: If you have a dual capacitor inside your AC handler this does not mean you already have a start capacitor. Likely; this is a fan run and motor run capacitor in one. 4. Most compressors (including the Bristol compressors I have) indicate the utility of a start capacitor and it’s size in the compressor data sheet.
