Please dont think I am an expert on everything, much less the SYSTEM I. I
just have mine a long time and really like it.

For anyone else that has the system I, here is what my 12+ year old motor
casing says:

Ser. 35ZB 55299R mod JAIM154N#...1.0A 3000RPM 1/45 HP .. Thermally protected. 

I still have the box, but no directions. Nothing about a warning, but could
be something that was added later.

I probably would not have read the instructions anyway.:-)

I tried this and it doesn't help the Vortex.

Of course water changes will remove a proportional amount of suspended
junk.  Water changes will only remove a small amount. A cloudy or green
water tank is still hazy even with 90% of the suspended stuff removed. IMO,
you have to remove 99.99... % to get it to be crytal clear. This is
difficult with water changes alone.

Mine is noisy too! But my wife tells me to close the door to the aquarium
room with either the Vortex _or_ System I running.
