Ok.......I have had the boat over a year now and have not used the a/c yet...... this Sunday I will be going to a marina with shore power and would love to test my a/c... I have a 2002 358....... what is the process of turnng on the a/c...... I know there is a ball valve in the bilige.....do I open that right before turning on the power or does that stay open all the time....... someone please fill me in....... I would like to overnite sometime in August and want to make sure it works........thanks in advance.....

Open it when you want to use the a/c., turn on the breaker on the electrical panel, and then turn to the a/c at the themostat.

Thanks NJ....... I will give it a try this Sunday.....

You'll love it. Makes overnighting a pleasure!
