The Aria Classic has a pedal-operated flush and ceramic bowl. Thetford's original illustration identifies its lower manual mechanism, return spring, water valve, blade seal and cable independently so a pedal or bowl-seal problem can be traced to the correct component.

Replacement parts and product photos
The white seat-and-cover assembly 33384 is a numbered part in the drawing. The additional chrome hand-sprayer listing is a related manufacturer-documented water-saver accessory, not a numbered callout here.
Check the model before ordering
Compare whether the toilet is high- or low-profile before identifying the foot-pedal cable: callout 8 lists 19835 for high and 19836 for low. The flush nozzle has newer white and bone replacement numbers, not just the original 36746 and 36747 labels.
