Recently I took on the task of opening my in-ground pool after frustrating experiences with pool company. With that said, I figured out (watching YouTube) how to set up the filter and make all the connections for water. Then came the Raypak heater, slid it in correctly, looked at the wiring and scratched my head. If anyone has some insight, experience, or even a pic of their Raypak heat wiring, I'd be grateful. This is a photo of what it looks like and one of the model number as well.
