When you receive a new appliance, write the 800 number on the manual as well as the model number and then take a picture of the front of the manual for your records. Then take the manual itself, slip it into a ziploc bag, and tape it to the back of the appliance, along with all paperwork that came with the appliance. If you need the manual at a future date, look for the appliance and the manual will be there.
