While it's soaking, blow it out and put it back in the water a few times. It will get fresh water to the wick faster.
It's a new atty, so you don't have to soak it long. When happy with it just shake it out, blow it out, probably best to do both directions. You could pulse the button a few times to get the leftover water boiled off, but there is a risk of popping the coil and rendering it useless. No risk to just adding juice and putting up with watery taste for a few minutes. It will wick better wet too.
Any sign of burnt, stop, add juice. No taste once you get going is when you redrip.
When you get to the point of a dirty atty from vaping, it's always best to blow from the battery end so you don't force chucks of juice char down into the air holes and wire compartments. When it's new you can do both ways without worry. It's not a bad idea to blow out your atty at the end of the day for maintenance and refill in the morning.
