I recently purchased a PS-5 Cal spa, 1996 model. Inside there is a cord for the ozonator and the main pump and they both plug into the control unit, however there is also a cord coming from the flow switch but I can't find where to plug this in. Anybody know where? I purchased an owners manual from Cal Spas but there is nothing in the manual and in fact the manual shows controls that are not even on my spa. Does anyone have any documentation they could fax or email to me? Forgot to mention, there is a sticker on the control unit (looks like installer put there) that is written PS-4 but on the plate outside the spa it does say PS-5.

Can anyone help? Hoping to get spa going before the snow flys.

Thanks
