Important Safeguards
Please read all instructions carefully before using your KEENSTAR Food Dehydrator. Retain this manual for future reference.
- Read all instructions.
- Do not touch hot surfaces. Use handles or knobs.
- To protect against electrical shock, do not immerse the cord, plugs, or the appliance in water or other liquid.
- Close supervision is necessary when any appliance is used by or near children.
- Unplug from the outlet when not in use and before cleaning. Allow to cool before putting on or taking off parts.
- Do not operate any appliance with a damaged cord or plug, or after the appliance malfunctions or has been damaged in any manner. Contact customer service for assistance.
- The use of accessory attachments not recommended by the appliance manufacturer may cause injuries.
- Do not use outdoors.
- Do not let the cord hang over the edge of a table or counter, or touch hot surfaces.
- Do not place on or near a hot gas or electric burner, or in a heated oven.
- Extreme caution must be used when moving an appliance containing hot oil or other hot liquids.
- Always attach the plug to the appliance first, then plug the cord into the wall outlet. To disconnect, turn any control to "off", then remove the plug from the wall outlet.
- Do not use the appliance for other than its intended use.
- This appliance has a polarized plug (one blade is wider than the other). To reduce the risk of electric shock, this plug is intended to fit into a polarized outlet only one way. If the plug does not fit fully into the outlet, reverse the plug. If it still does not fit, contact a qualified electrician. Do not attempt to modify the plug in any way.

Operating Instructions
Control Panel Overview

- TIME Button: Used to adjust the dehydration time.
- TEMP Button: Used to adjust the dehydration temperature.
- SET Button: Toggles between time and temperature settings for adjustment.
- Up/Down Arrows: Used to increase or decrease the selected time or temperature value.
- START/STOP (Power) Button: Turns the unit on/off and initiates or pauses the dehydration process.
Preparing Food for Dehydration
- Always wash and clean food thoroughly before preparation.
- Slice food into uniform thickness to ensure even drying. Thinner slices will dry faster.
- Some foods may benefit from pre-treatment (e.g., blanching vegetables, soaking fruits in lemon juice) to prevent discoloration or improve texture. Refer to the included recipe book or a reliable dehydration guide for specific recommendations.
Loading Trays

- Arrange prepared food in a single layer on the stainless steel trays. Ensure there is enough space between pieces for air to circulate freely. Do not overlap food.
- For smaller items like herbs or berries, use the provided mesh screens to prevent them from falling through the tray grids.
- When making fruit leathers, spread pureed fruit evenly onto the fruit roll sheet.
- Carefully slide the loaded trays into the dehydrator.
Setting Time and Temperature
- Plug the dehydrator into a standard 120V AC power outlet.
- Press the START/STOP button to turn on the unit. The display will illuminate, showing default time and temperature settings.
- Press the SET button to select either the TIME or TEMP setting. The selected value will flash on the display.
- Use the Up/Down Arrows to adjust the desired time or temperature.
- Press SET again to confirm the setting or to switch to adjusting the other parameter.
- Once both time and temperature are set, press the START/STOP button to begin the dehydration process. The unit will start heating, and the internal fans will activate.
Monitoring and Completion
- The transparent door allows you to monitor the drying process without opening the unit, which helps maintain consistent internal temperature.
- Periodically check the food for your desired level of dryness. Drying times can vary significantly based on the type of food, its thickness, and initial moisture content.
- When dehydration is complete, press the START/STOP button to turn off the unit.
- Unplug the dehydrator from the wall outlet and allow the food and trays to cool completely before removing them.
- Store dehydrated food in airtight containers in a cool, dark place to maintain freshness.
Dehydration Guidelines
The following table provides general temperature and time ranges for common foods. These are approximate values; actual drying times may vary. Always ensure food is thoroughly dried for safe storage.
| Food Type | Temperature Range | Approximate Time |
|---|---|---|
| Fruits (e.g., apples, bananas, berries) | 130-140°F (54-60°C) | 6-20 hours |
| Vegetables (e.g., carrots, zucchini, tomatoes) | 125°F (52°C) | 4-12 hours |
| Meats (e.g., beef jerky, poultry) | 145-160°F (63-71°C) | 4-15 hours |
| Herbs (e.g., basil, oregano, mint) | 95-105°F (35-40°C) | 2-6 hours |
| Dog Treats | 145-160°F (63-71°C) | 4-12 hours |




Maintenance and Cleaning
Regular cleaning ensures optimal performance and extends the lifespan of your dehydrator.

- Unplug and Cool: Always unplug the dehydrator from the power outlet and allow it to cool completely before cleaning any parts.
- Clean Trays and Accessories: Remove the stainless steel trays, mesh screens, and fruit roll sheets. These can be washed by hand in warm, soapy water or placed in a dishwasher (trays are dishwasher-safe). Rinse thoroughly and dry completely.
- Clean Main Unit: Wipe the interior and exterior surfaces of the main dehydrator unit with a soft, damp cloth. For stubborn food residues, use a mild detergent on the cloth. Do not immerse the main unit in water or any other liquid.
- Drying and Storage: Ensure all parts are completely dry before reassembling or storing the dehydrator. Store the unit in a clean, dry place.
- Avoid Abrasives: Do not use abrasive cleaners, scouring pads, or harsh chemicals, as these can damage the surfaces of the dehydrator.
Troubleshooting
If you encounter any issues with your dehydrator, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Dehydrator does not turn on. | Not plugged in; power outlet issue; unit not switched on. | Ensure the power cord is securely plugged into a working wall outlet. Press the START/STOP button. |
| Food is not drying evenly. | Food sliced unevenly; trays overloaded. | Ensure food is sliced to uniform thickness. Do not overload trays; arrange food in a single layer with space for airflow. The horizontal airflow system is designed to minimize uneven drying. |
| Dehydrator stops during operation. | Overheat protection activated. | Unplug the unit and allow it to cool down for at least 30 minutes. Plug it back in and restart the dehydration process. Ensure proper ventilation around the unit. |
| Unusual noise during operation. | Trays not properly seated; foreign object inside. | Ensure all trays are correctly inserted and seated. Unplug the unit and inspect the interior for any obstructions. |
