Testing out strobe and setup

I've just received delivery of my first strobe, and it says it's for underwater use only (doh!). Is it ok to hook it up and fire a few test shots to make sure the cabling, triggering, strobe levels, etc. all work properly? Can this be done on dry land? Or would that cause damage to the strobe? I can't believe I'm asking this question, but having not used an underwater strobe before, wanted to check. 

You can do it on dry land, it shouldn't overheat if you do one test. Use minimum power

A few test shots in air are fine. If you want to do something stressful, like fire a long burst, put it in a bucket of water first.
