Thanks for the helpful advice. We had already printed the owner's manual from the website and were able to learn a lot. But sometimes it helps to have people point out the obvious and share lessons learned too.
We have cleaned the spa, and are now filling it.
Power should be running in the morning and we hope to open up all the jets and valves and put in the cleaners and get everything nice and clean. Then we will drain again, replace the filters with new ones and fill 'er up again with chems and start getting the water just right.
If all goes well, we hope to have our first soak by Friday or Saturday night (but it sure takes a long time to drain and fill up!!). We are taking some pics too.
