Can the pump be wired for either 110 or 220 when delivered?
Where would the waterfall be located on this unit?
Can it be equipped with the automatic brominator?
The 110 volt spas can be switched from 110 to 220 via some jumper switches.
Going to 220 volt would increase the strength of the heater (same heater, just more power).
The waterfall would be on the one side of the spa, roughly at center.
There is the ?Natural Saltwater System/chlorine generator option on available on the website. It is nice in that it works on either 110 or 220 volt setups.
It is possible to get a saltwater / bromine generator, but it only work in the 220 volt version, so you would have that as a restriction.
