Presto Dehydro Instructions Manual page 3

1. Remove trays and cover from unit.
2. Turn over power base and unwrap cord.
3. Set base, right side up, on a dry, level surface. In order to function properly, the dehydrator must have sufficient airflow; therefore,
be sure the base and cover vents are not obstructed at any time. Never place dehydrator on carpet, a towel, or newspaper.
4. Each tray has raised ribs on one side. Food goes on the side of the tray without raised ribs (Fig. B1, page 2). Feel for the raised
ribs to ensure you have the tray properly positioned before loading it with food. The raised ribs should always be facing down
during use (Fig. B2, page 2).
5. Select a tray with handles. Set the tray on the counter with the words on the handle "THIS SIDE UP" facing up. Begin loading
tray with a single layer of food. Do not place food over the center hole.
6. Place loaded tray onto power base. The first tray placed onto the power base MUST have handles (Fig. A, page 2).
NOTE: A minimum of two trays is needed to operate the dehydrator.
7. Select a tray without handles and set it on the counter with raised ribs facing down. Load tray with food and stack tray without
handles onto tray with handles.
8. Continue filling and stacking trays, alternating trays with handles and without handles (Fig. A, page 2).
9. Place see-through cover over stacked trays. Position cover so the words on the cover handles "THIS SIDE UP" are facing up.
10. Plug cord into a 120VAC electrical outlet only and begin dehydrating. See pages 5 through 10 for dehydrating information for
specific foods.
The digital control (Fig. C) allows for easy selection of dehydration temperature and time. In addition, it will automatically shut off
the dehydrator when the selected time has elapsed.
