If the outlet is down the air may not have anywhere to go so the pump may start up dry. It should push the air out soon enough in a big cloud of micro bubbles but it may cause an air lock.
I've never tried it but like I said, I'm just thinking out loud.

Good observation. With an Iwaki pump, you should be able to rotate the pump housing on the motor to avoid that possibility. Probably wouldn't be able to turn the outlet vertical due to the mounting method, but at least to the side would be better. It would likely also simplify the plumbing.
