I have just bought my first hot tub - used and old - and I am unsure about some of the controls.
In the picture there are 2 jet pressure controls on the left and right - I think.
However, on the top and bottom I am unsure. The bottom one hase some sort of a check valve and an air line going to it (also not sure where the line goes since it has rotted away). and the top had nothing screwed into the threads however I can see a second broken air line unde it - (I had poked the line up throught the hole in the pic). Can anyone help ID these parts, explain what they do, how they work.
Also, I don't know the model of this spa but it is a Sunwave spa and the date on the spa pack says 1990. I have found nothing on the net as far as documentation on this spa. Can anyone help there as well?

Much thanks,

RobMan

How bout a back side photo? (Rotted guts and controller/equipment included) This is like looking at the wrong side of a.... ahh never mind... We need the whole enchilada. If someone showed me this with no explanation, I'd say you had two air control knobs (that control jet pressure), and a circa 1982 design light switch on the bottom with an ancient exit hole for a 1985 or so multifunction controller pad. Aside from that this is greek. And you ain't gonna find no drawings or schematics for this tub as they don't exist unless you've found klinger hanging out in a hole somewhere with the secret stash... and that wire looking thing sticking up, it looks like I'd want to keep it away from my ear lest it crawl in and invade something up there... You know what I mean... " title="Smile" /> " title="Twisted Evil" />

Ha Ha.
Don't be makin' fun of my tub man! LOL

Yea. It looks pretty scary in this photo. The picture was taken when we picked it up out of a lady's yard. It had been sitting on its side unhooked for quite some time and covered in mud and ants.
It has since cleaned up real nice and I am planing a test run tomorrow to see if the pack works. I just got the electrical run tonight.
I will take some more photos at different angles as soon as my wife finds the charger she lost that goes to my camera!

Thanks for the insight Pageup. I wish I knew what was screwed into that empty hole on top in the photo.
There are (3) 1/4'' air lines that run under the hot tub. I think they are all for switches?

One button mounted on the surround panel - turn the spa on/off ?
The two upper and lower areas in the photo - lights and blower?

Sound right?

Thanks again
