I tried to post this message back on Monday, but it never showed up. I hope it works this time because I am trying to hook this thing up by my pig roast on the 10/21. Please help if you can!!

I recently bought a used Cal Spas Traditional series spa. It came with a cal spas heater PS-4-? (0 I think). I have four water lines coming from the tub, but only two that I can see coming into the heater and or pump. The tub only appears to have about 5-8 jets. Two of the water lines are ~ 1 in diameter. One is capped off and the other looks like it was broken or cut off of one of the jets. However, I cannot see anywhere that it has been removed. The other two lines are larger (~ 2in). One of the big lines appears to connect to the pump. The other seems to connect to the flow regulator, but I cannot find how to hook the flow regulator to the pump or heater. I know this is a large posting, but one last thing. The guy I bought this from said that he gave me everything I needed to run this tub properly. However, I noticed a spot on the heater to plug in a blower motor. Do I need a blower motor, or is it just an option? Thanks in advance for any help anyone can give.
