The house I recently purchased came with an old self-contained spa outside. I've spent the past hour looking the various names and numbers I can find on the unit trying to identify it, get the manual, and someone locally who can service it. Haven't had any luck.
Closest I get are various sites with Ramco / CRL replacement controls. Basically trying to get an idea on its age and specs.
Filled up the tub above the filter (whole tub really needs to get cleaned though). Flipped the breaker on. The EP2 power light doesn't turn on. Pressed the GFCI reset and a click comes from the EP2 unit. Every ~10 seconds, the spa pump makes a noise like its trying to turn on or something and then off again. None of the controls on the top do anything except make a click (which I assume is some internal relay) in the EP2.
