*Note: If your Model D4, IHS12-D4 or IHS22-D4 is equipped with a solenoid valve or UV intensity monitor (Model D4+), or if you have the D4 Premium model with full color LCD display, you will need to use this ballast as the replacement. However, if you have a basic D4, IHS12-D4 or IHS22-D4 unit and you are not using an emergency solenoid shut-off valve, you can use the basic D4 controller if you prefer: UVMax Basic Controller #650733R-002.

For current customers with an older generation UVMax Model, this new replacement ballast includes an upgrade over your current ballast - it features a large color LCD display!
