Keep your spa water at its freshest by installing a renewal kit in your ozone generator every 12 to 18 months. Extending the life of the ozone generator, this kit is easy to install and will help you further reduce your environmental impact by eliminating the need to replace the generator entirely. This translates into less energy use in production and transport, less material use, and less energy spent in recycling. Reduce, reuse, recycle, renew. Spa Eclipse™ and CDS-16 Renewal Kits include 5-0561 replacement chip, 5 feet of tubing, 7-1140-01 check valve and four hose clamps.
