A Little More Awareness

A little more awareness would have gone a long way towards my installation of the new spa pack. I usually read directions but this came without specific directions just diagrams and pictures. I followed the diagram to wire the equipment. However the internal wires did not.

In the diagram the wires are from the top, Ground, White, Black, Red. But on the new device it is obviously wired Red, White, Black and the Ground is separate. I found the ground connection but did not see that the wiring was different from the diagram. That meant that I sent 256 volts to the GFCI frying it and to the board also frying parts on it. What a huge mistake that was! I have to send the entire system back for repairs.

Another mistake was during the installation of the UV/Ozone Sanitizer. It requires a small plastic check valve that only works one way. That is the definition of a check valve. It was unclear to me which way the valve was installed. It did not have an arrow marking on the valve itself. I tried to deduce from the diagram by looking at the slightly domed side. Of course I judged incorrectly and the water leaked back into the sanitizer. I took it apart and did not see that it would have been damaged as the light was above the trickle of water that came through the case.

Before the support person, Joe at Acura Spas, spotted the bad wiring when we tested the system. Unfortunately the tests on the main board yielded the correct voltage even though I had them wired incorrectly. He told me that the GFCI seemed to be broken so I tested the plug voltage going to the transformer and it showed 256 volts! That is when he double checked the photo I had sent him and realized the wiring had probably damaged more than the GFCI.

Even after I rewired correctly and removed the GFCI, the top panel did not light. That showed damage to the transformer and probably other parts.

The solution to this fiasco was to box everything up and send it back to the manufacturer for repairs. He said he would go easy on the cost of labor but the shipping both ways will be expensive. I’m sending back all the equipment from the UV sanitizer to the spa pack to the top panel control so that they can be sure it all works together and I can reinstall it correctly.

I’m very sad about this error. Not that it affects the overall spa that much but I feel embarrassed that I didn’t wire it according to the wires in the box instead of a diagram that was outdated. No decent electrician would have made that error. It is humbling.
