Need help with Active Aqua air pump getting to hot

I need a little help i just started using an active aqua pu110 air pump and to me it seems like its getting pertty hot.This is my first time using an air pump like this so i dont know if they get this hot maybe they do i just dont know.Maybe i shouldnt be using it non stop maybe i should be giving it a break i dont know i thought u just let it run all the time,im doing bubbleponics for my first time and need all the help i can get.Can somebody please shed some light on this subject for me.Thanks for the help.

So it should be hot to the touch that is not a problem.Can i run it 1 hour on,15 min off will that help with the heat or should i not worry about it.

You might want to email the manufacturer.

They really shouldnt get hot. I would contact the manufacturer like Pasta said. They should run without the heat.

Best of Luck and Wishes to ya
