NOTE!
Observe aerator for vortexing:
A vortex is created when air is sucked from the water's surface directly to the
propeller by bypassing the draft tube. Loud "slurping" noises usually
accompany a vortex. Occasional vortexing will not damage the aerator. The
aerator should be adjusted if it vortexes more than twice a minute or if a
vortex continues for more than 10 seconds. Typically, rotating the aerator
deeper into the water (at an angle of 45° or greater) will decrease vortexing.
Another option is to install a vortex shield. (See 6.2)
