Spring 2022 DEL Ozone released these new Retrofit Kits for the OZONE 100 (EC-40).  They do not work in the original model, the EC-4.

The R1020900 (previously 9-1678-03) for OZONE 100 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 100:

• Less money than updating to a new OZONE 100 (Part Number EC-40)
• 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 100:

• 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 40 to OZONE 100.  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 25 and OZONE 50:

• R1020700 (previously 9-1678-01) for DEL OZONE 25
• R1020800 (previously 9-1678-02 for DEL OZONE 50
