Before using your dehydrator for the first time:
Remove the trays and wash in warm water with small amount of dish soap. Set up Fast
mode and let machine run for 1 hour.
1. Always keep the Dehydrator on a flat surface.
2. Keep the Dehydrator at least 4 inches away from walls, other appliances or furniture.
3. Open the door to insert trays into the Dehydrator. Hold the tray in the horizontal position and
push the tray into the proper slots.
• Place the food evenly and neatly on each tray as close as possible. For best results, cut the
food into even sizes and thickness so that dehydration will be completed altogether.
• It is recommended to use separate trays for each type of food.
• Double check whether all the trays are properly loaded.
4. Plug into an outlet that has 10-amp capacity. Do not plug into an extension cord.
5. Turn the main switch ON.
For TST Mode Only
The Two-Stage Sequential Temperature-Timer (TST) is a two-phase combo mode that allows
for both Fast mode and Slow mode to be applied sequentially.
Steps:
Turn the Dehydrator on. The indicator light will be lit on the panel.
Press the “SET” button three times and then the TST mode starts automatically.
About Two-Stage Sequential Temperature-Timer (TST)
The initial temperature starts at 167°F for the first 2 hours and then the temperature
cools down to maintain at 145°F for 6 hours. When the full food dehydration cycle
completes in 8 hours, the dehydrator automatically switches to Keep Warm for 24
hours and switches off afterwards.
According to the USDA’s current recommendation (as of 2017), to make jerky safely is
to pre-heat meat to 160°F and poultry to 165°F before the dehydrating process starts.
The TST function is designed to sterilize meat and poultry for making jerky, and which
might not be ideal for fruits and vegetables due to the high temperature.

Cleaning and Maintenance
• Clean the trays and drying sheets with a mild detergent under warm water after each use.
NOTE: The Stainless Steel trays are dishwasher safe.
• To clean the Main Body, first unplug the machine and then clean with a wet towel.
• Do not rinse with water or submerge the machine in water.
• For easier screen/tray cleaning, cover with wet paper towels and soak for a short while.
• Make sure the trays and drying sheets are thoroughly dried before inserting them back into
the Dehydrator. Keep your machine and machine parts in a safe place, out of reach of
children.
Dehydrating Tips
Keep these tips in mind when dehydrating fruits, vegetables, nuts, or spices:
• It is best to use fruits and vegetables that are in season, grown organically/locally.
• Use fruits or vegetables with appropriate firmness, with no soft spots that discolor during
dehydrating.
• Remove unwanted parts: stalks, cores, unwanted seeds, rinds or outside skins, peels if
desired.
• Keep slices the same size. This will help dehydrate more evenly and the dehydrating time
will stay more consistent.
• When spicing (e.g. BBQ or salty flavors), coat foods with something wet, sticky, or oily to
help the spices/flavorings adhere to the foods/chips better. Olive oil, miso, liquid marinades,
or sweeteners like honey or agave work well.
• Store in sealed containers to keep the food longer after dehydration.
• To re-hydrate (if you over dry), put a moist paper towel, add a lettuce leaf into the container,
or lightly mist the foods with water to re-hydrate back to desired texture.
NOTE
If the tempered glass door is opened while the dehydrator is in operation, power supply to
both the heating coil and the fan will be turned off. The machine will automatically restarts as
soon as the door is fully shut.
When you hear a beep sound and see E1 on the display screen while the door is opened,
it is not a program error but a signal that the door is not fully shut. Just try to shut the door
completely.

Fruits
• Fruit chips are tasty and a good way to save extra produce for camping, hiking, or for later use.
• Use crisp fruits, or fruits not overly ripened for best results.
• Most dehydrated fruits taste less sweet than fresh fruits, especially banana chips, so putting
a desired spice (e.g. cinnamon, nutmeg, or vanilla) or sweetener (e.g. agave, stevia, or maple
syrup) on top of each chip can sweeten the finished food.
• Make sure to remove cores, seeds, and other inedible parts (peels, etc.).
• When using larger pieces (e.g. a small apple, pitted fruits, or bananas) keep them the same
size to keep the drying time the same and dehydrate more evenly.
Grains
• Best to soak/sprout grains before dehydrating; two or three days is sufficient.
• Grains can be sprouted and dried back in order to make a sprouted flour.
• Savory or sweet crackers and breads can be made by combining the grains with spices,
herbs, vegetables, dried fruits, or even the pulp from juices.
Nuts
• Soak nuts initially in enough water to cover entirely, then add a splash of hydrogen peroxide into
the soaking water and rinse thoroughly after 5 minutes (this gets rid of unwanted mold).
• Softer nuts (e.g. cashews or pecans) hardly need any soaking. Just the initial soak/rinse (as
mentioned above with hydrogen peroxide) to remove unwanted molds.
• The harder nuts (e.g. almonds, brazil nuts) need to be soaked for longer (between 6 - 12 hours),
after the initial soaking/rinsing.
• Drying soaked nuts keeps them fresh longer, without the enzymes that coat the nuts that inhibit/
block digestion. They can take up to 48 hours to fully dehydrate, depending on the size of the nut,
the weather (more humidity takes longer), and how long the nut has soaked.
• After a nut has been soaked and dried, it can be ground into a flour and used in other recipes.
Seeds
• Soak seeds to remove the coating that protects them from automatically sprouting into a plant.
• If you want to make a flour, soak and dry the seeds so that you can grind them.
• Soaked seeds combine well with all the foods (vegetables, fruits, nuts, or grains) in many
dehydrated recipes. They act as a thickener, as well as add their own lovely flavors.
• Combine to make cereals or granolas.
• The Fast mode is fine for solo seed snacks.
Spices
• When using fresh herbs, remove the stems and stalks or anything else inedible.
• Use a baking sheet to avoid having herbs drop out of the screen/tray.
Vegetables
• Dried vegetables (carrots, corn, zucchini, mushrooms, etc.) can be great foods to use for soups
later in the year, when the food is out of season, or to take on camping/hiking trips.
• Cut into uniform sizes/shapes when dehydrating.
• Take off skins, seeds, and other unwanted parts before dehydrating.
•
Some vegetables (e.g. onions) get more spicy/hot flavored when dehydrated and some get sweeter.
