FRUITS: To rehydrate dried fruit, cover with boiling water and let sit for 5 minutes, drain.

VEGETABLES: Vegetables should rehydrate to almost the same size as they were when fresh. Cover vegetables in cold water

and allow food to soak for 30 minutes to 2 hours. It is not necessary to rehydrate prior to using in soups and stews.

1. Vacuum sealing is ideal for keeping dried foods.

2. Store in portion sizes which will be easily used at one time.

3. Store in a cool, dark, dry place.

4. Store in air tight, moisture resistant containers.

IMPORTANT SAFEGUARDS

When using electrical appliances, basic safety precautions should always be followed. Read all instructions

carefully and save these instructions for future reference.

Meat being used for jerky should be as lean as possible. Using lean meat will help the meat dry faster. Ground meat should

be 79%-90% lean. Ground turkey, venison, bualo and elk are other excellent choices for jerky. Jerky seasonings are available for all

tastes (available at lemproducts.com). Whenever jerky is being made, cure (available at lemproducts.com) should be used. Cure is

used to help prevent botulism during drying at low temperatures. Follow the manufactures directions on the cure packet. Marinate

meats in the refrigerator. Do not leave meats unrefrigerated. Always wash hands thoroughly with soap and water prior to and after

working with meat products.

Special consideration must be made when using venison or other wild game, as it can become heavily contaminated

during eld dressing. Venison is often held at temperatures that could potentially allow bacteria to grow, such as when it is being

transported. Refer to the USDA Meat and Poultry Department for further information on meat and food safety.

When using a dehydrator, check the temperature of the dehydrator with a dial thermometer (available at

lemproducts.com) before drying jerky. The minimum recommended temperature for drying meats is 145º F. IMPORTANT: Before you

place the meat in a dehydrator, it is highly recommended by the USDA to heat the meat to 160˚F (poultry to 165˚F) BEFORE the

dehydrating process. This step assures that any bacteria present will be destroyed by heat. After heating to 160º F, maintaining a

constant dehydrator temperature of 130-140º F during the drying process is important because: 1) the process must be fast enough to

dry food before it spoils; and 2) it must remove enough water so the microorganisms are unable to grow. For more information go to

www.usda.gov.

If you are using a marinade, shake o excess liquid before placing the meat in evenly spaced single layers approximately

¼” apart on the racks. Dry meat at 145-150º F for 3-5 hours. You may need to blot fat droplets from the surface of the meat

occasionally, using a paper towel. Drying times may vary based on many circumstances, including but not limited to: the relative

humidity of the room, the temperature of the meat at the beginning of the drying process, the amount of meat in the dehydrator,

leanness of meat, etc.

IT IS IMPORTANT TO READ & UNDERSTAND ALL OF THE INSTRUCTIONS

Make sure power switch is turned o. Place the unit on a clean, dry surface away from children

and pets. Plug into an undamaged, grounded electrical outlet.

1. Follow your recipe for the food that you wish to dehydrate then place the food evenly on the shelves provided. You can use

cooking spray to help prevent sticking. DO NOT allow food pieces to touch or overlap.

2. Carefully place shelves onto the brackets inside the unit and slowly slide them in, do not force shelves. Forcing shelves further

than necessary may cause damage to the fan guard, fan or heating assembly.

3. Slide door into place. Turn power toggle switch on and set desired temperature by turning the corresponding knob on the top

of the unit. Monitor the internal temperature and adjust as needed. Unit WILL NOT OPERATE until timer switch is set to;

“ON” for continuous running OR the number of hours you want the unit to run. The unit will shut o automatically

after the set time has elapsed. You must turn the timer o when using “ON” setting.

4. Fan will run continuously when in operation. (If fan does not run, turn o unit and unplug from outlet and call LEM Products

877-536-7763 for technical assistance.)

5. Periodically check for even drying or your product. If drying is uneven, use oven mitts to rotate or rearrange the shelves up or down.

6. When dehydrating is complete, use oven mitts to remove the front panel by sliding it straight up. Set it aside on a

heat-resistant surface. Slide shelves out and remove nished product.

7. Note: Moisture may collect on the bottom of the unit during operation and can be wiped out with a paper towel.

WARNING: Unit may be hot. Avoid touching the walls and shelves with your bare hands as burns may result.

BEFORE CLEANING OR SERVICING THE DEHYDRATOR, UNPLUG UNIT FROM POWER SOURCE.

Prior to rst use and after each use:

• Allow dehydrator to cool completely before cleaning.

• Remove the shelves and drip tray from the dehydrator and wash in warm soapy water.

• Wipe the door, interior and exterior of the dehydrator with a moist sponge or soft cloth. DO NOT use scouring pads or

abrasive cleaners. Be careful to not splash water onto the heating element or other electrical parts in the rear of the

dehydrator. NEVER immerse the dehydrator cabinet in water or other liquid.

• Allow dehydrator to dry completely prior to storage.

• Keep in a cool dry place.

THE THERMAL PROBE SHOULD NOT BE REMOVED. TO AVOID ELECTRICAL SHOCK THE PROBE MUST BE PROPERLY

INSTALLED AT ALL TIMES. DO NOT ATTEMPT TO REMOVE, RELOCATE OR ALTER THE PROBE IN ANY WAY.

Cuts, injuries and/or re may result from non-compliance with all operating procedures

described within this instruction manual.

BEWARE! HANDLE CAREFULLY! SOME SURFACES MAY BECOME VERY HOT DURING USE!

Serious injury may result! DO NOT move the dehydrator while hot,

allow the appliance to cool before handling.

TO OBTAIN THE BEST RESULTS:

1. Choose high quality foods. Do not use foods with bruises or blemishes.

2. Wash food, use clean utensils and keep your area clean.

3. Pre-treat foods to prevent discoloration.

4. Always use lean meats. Remove as much fat as possible prior to dehydrating.

5. Blanch food with skins prior to dehydrating. This process will lock in color and avor as well as soften skins of things like

grapes, cherries and plums.

6. Do not overlap foods. Air must circulate. Lay foods at and spaced on the trays.

7. If uneven drying is noticed, rotate shelves 180˚ or rearrange up or down.

8. Check dryness every 2 hours until crisp, pliable or leathery depending on the product. Cut item in half and check internal

dryness. If food is still moist, dehydrate longer.

9. Drying times may vary depending on room temperature, relative humidity and moisture levels in the food you are drying.

Drying time is also aected by the amount of food placed on the shelves. Overloading shelves will slow drying time and

may produce poor results. Use the food drying guide on page 7 as a reference.

10. Use the food drying guide on page 7 as a reference for proper temperature. Drying foods at higher temperatures may cause

food to harden. Food may be dry on the outside but the inside may still be moist.

11. Cool food before testing for dryness.

12. Proper storage is essential to maintain the quality of the food. Food should be at room temperature prior to storing.

Vacuum sealing is ideal for keeping dried foods.

13. Choose foods that are similar size and shape for uniform drying time.

ISSUE: Food is sticking to the trays.

RESOLUTION: After rst hour turn food over.

RESOLUTION: Prior to putting food on trays, spray or coat trays lightly with vegetable oil.

ISSUE: Mold is on dehydrated food.

Storage container was not air-tight.

Food was not uniform in size which caused uneven drying.

Food was dried at too high a temperature.

Exterior was dried and hardened, but interior was still moist.

RESOLUTION: Test several pieces of food for dryness.
