Welcome to our forum.
I have a brand new Caldera spa being delivered to my house on Monday. I live in Chicago and the dealer received the tub this week. It has been stored outside.My question is how warm does the tempature have to be outside to start it up for the first time? Is there some residual water in the pipes or pumps from the factory that could be frozen and I should be concered about? Do I need to wait for a break in the weather before starting it up? Thanks ,Doug
