my husband and I recently bought a D1 spa used and have had a few problems. the guy we bought it from didn't drain it correctly over the winter and froze some of the pipes and casings. also the ozone generator doesn't work and can't seem to figure out all of the wiring, the diagram is missing. any info would be helpful. thanks

If the pipes froze, expect to chace down some leaks. The ozone generator would be my least worry at this point, as it is only a luxury, and depending on the age of the spa and the generator, it may need to be replaced anyway.

I am sorry but I can't help you to obtain a schematic for that tub.

well we have fixed many leaks.......alot!!! Have a question, we replaced the apollo air pumps with the bellows, and tested the apollo inside. It came on when we tested it in the house. Any idea why it would not work when in the spa??? By the time we get done this is going to be a brand new spa.
