Wasn't sure if this whould be posted here or in the "Spa Use/Care" thread.
Just got a new(used) hot tub and I have some questions about the Spa Pack(pump and heater part).
The heater is a Pinnacle systems PE-40 A-L-G. It has a 120(1.375KW)/240(5.5kw) heater and I plan to run it on 120.
There are four wires coming out of the unit. Green/Yellow, Red, Blue, and White. I know the Green/Yellow is ground and am assuming the White is Neutral, am I correct? What I don't know is when using 120v do I use the Blue wire or the Red one?
Here's a pic of the wires.
The other question I have is about these two switches inside the unit. One is for 120 or 240v operation, and the other one just says R or D. What does R and D stand for/mean?
Here's a pic of the switches. They used to be at 240v and D when we got it, but I flipped both of them before taking the pic.
Also, does anyone know where I can find a manual or the companies website? All I can find are online retailers selling it.
