Spring 2022 DEL Ozone released these new Retrofit Kits for the OZONE 25 (aka EC-10).  They do not work in the original model, the EC-1.

Then in Spring 2024, new Retrofit Kits are created and the part numbers change.  R1020700 is the new Part Number for 9-1678-01. 

This Retrofit Kit for OZONE 25 gives you the ability to update to modern technology.  Add a Check Valve Assembly (9-0770-01) to your order to keep your system running for years to come (change these annually).

PROS to updating your OZONE 25:

• Less money than updating to a new OZONE 25 (aka Eclipse 10)
• Putting the Retrofit Kit inside the Eclipse is relatively easy to do (if you're handy, you can do it!)

CON to updating your OZONE 25:

• You lose the outside indicator light(s)!  This is a big bummer for some people and there is no sensible way around it.  Every year when you change the Check Valve Assembly (9-0770-01), open the Eclipse and look at the internal LED indicator lights (one light on each APG Ozone Module)
  

December 2017 DEL Ozone changed the name from Eclipse 10 to OZONE 25.  Spring 2022 DEL Ozone updated their OZONE 25, 50 and 100 models with 9-1636-01 Ozone Technology.  This is GREAT NEWS as these are a great improvement over the 9-1056-01 Ozone Module.  

The following Retrofit Kits are available for OZONE 50 and OZONE 100:

• R1020800 for DEL OZONE 50 (previously known as 9-1678-02)
• R1020900 for DEL OZONE 100 (previously known as 9-1678-03)
