The Deni company apparently is no longer in business, so their web page doesn't respond. Critical web page note do not suggest support available from the company for over 5 years.
Some manuals for other models appear on the internet, but I did not see that one in a digital form. You may want to search yourself and view those using https://www.google.com
The only printed 9350 manual I could find is for sale with the fryer on the following link if you want to purchase it.
