The 9-1636-01 is a new and improved ozone module that is used in current models of DEL Ozone generator. The older ozone module, 9-1056-01, is now discontinued. If you have an original Eclipse 1, Eclipse 2 or Eclipse 4 which were released in 1999, the new 9-1636-01 will NOT work. It is officially time to upgrade your ozone system. The Eclipse 1, 2 and 4 Ozone Generators were eventually upgraded and renamed Eclipse 10, Eclipse 20 and Eclipse 40. The easy way to tell which ozone system you have is by the color of the generator. If it is silver-colored, it is antiquated and you cannot upgrade it. If it is black you can replace the ozone module with the new 9-1636-01 by using the Retrofit Kits below:

OZONE 25 (EC-10) utilizes R1020700
OZONE 50 (EC-20) utilizes R1020800
