i do apologize for the inconvenience that your having with the noise. usually the screeching noise means something is rubbing up against something inside, or a part that helps the unit run needs to be cleaned or greased. to do the internal the best thing that i can suggest is to take it to a hardware store and see if they can clean it there for you.

These units usually put out ozone into the air in your home which is a known lung irritant. Sometimes they will call it an ionizer or something like that. If you truly have indoor air quality issues the only way to properly attack it is through three steps
source control - what's causing it(uv lights to kill it usually)
ventilation - bring in fresh outdoor air and exhaust stale indoor air(ERVs and HRVs depending on your climate some dealers won't sell these if they don't offer it to you they are dumb find someone who does they are Recovery Ventilators)
filtration - a whole home filtration system (look to dealers who carry Lennox who is the only company with a 100% ozone free product line and the highest filtration rates available on the market "MERV 16" filters or Trane is ok as well as Carrier systems)
You can look up the Lennox Merv 16 filter it was rated #1 in Consumer Reports december 2007 as the best whole home air filter above the trane clean effects and others. can be bought and installed for around 400 bucks to 1000 dependeing on how hard it is and ask about the pure air system if you want higher levels.

Best practice is to contact manufactures and ask for name and address of closes retailer for that company

I tried to locate the manual with google, but unfortunately had no success. You could ask some specialized manual search engines, like here or here. The services are not for free, but most times worthy - saved my live more than once.

go to your local hobie shop these guys are a wiz at gluing things back together and will set you up with the stuff needed to do it right the first time . bring it with you and ask for help on doing the repair .. ja the pool pump repair guy in longwood fl

these things are junk. you could also be doing more harm than good to yourself and the indoor air quality in your home with the amount of ozone these appliances omit into the air. throw it away
