A great option you have is to get the BoxPlunge control box Then, this filter which can be directly plug into the control box above and then you'll just need the box 10 liner. The control box is not only the thermostat but also has an ozone with a timer, the safety system disconnect, a plug for the filter, a mounting system and the safety system disconnect (everything de-energizes upon lid aperture).
