I recently purchased a used waters edge hot tub model EX200ss. It can be set up as either 110 or 220. I am attempting to wire it now, but can't tell if it was previously set up for 110 or 220. I also cannot find a manual for this brand as it is now out of business. There is a switch right at the front of the box, but it is unlabeled so I don't know what it controls. Can anyone help?

maybe posting a pic would help.
my jacuzzi had a jumper on the control board that was on 110v when i got it so i knew it was ready for 110 maybe look around for a jumper on the control board. hope this helps.
might want to post up requesting a manual for it..
maybe someone on here has one.
or better yet do a search on here for your model and see if you can find someone on here that has the same and Email them see if you can get a copy of it.
