a friend sold me his calspa 2000 for $400 dollars along with the steps and the cover. It is in very good condition and him and his wife had it stored indoors. Is just had it moved to my home and put on a patio slab that I had put in place specifically for the spa. My friend also gave me the gfci 220v box that i needed. My friend said it has been working perfectly for them but they are moving and didn't want to haul it several states away.
Is there anything specifically that I should check on this unit before having it wired up. The ozonator was replaced in mid-1999, anything else i should have specifically looked at?
Thanks!

well it is all hooked up and running at a constant 100 degree temp. Had to replace the ozonator, but other than that..everything seems good to go. I have it set to filter 3 hours out of every 12.
