Congratulations on your purchase
Wartmann® hopes you will enjoy your new dehydrator. With the Wartmann® dehydrator you’ll be able to
dry your own fruit, vegetables, fish and meat. The dehydrator comes with ten stainless steel trays and a drip
tray.
An excellent choice
The Wartmann® dehydrator has a stainless steel housing, a built-in fan and an 800 watt heater. A glass door
provides for a clear view on the inner side when dehydrating. The solid materials used make the Wartmann®
dehydrator sturdy and sustainable.
Please follow this instruction manual and maintain your Wartmann® dehydrator as described and your
dehydrator will provide you with years of pleasure.

IMPORTANT
This manual contains information about the use and upkeep of the Wartmann® dehydrator. Read this manual
carefully before you start using the Wartmann® dehydrator and keep this manual for possible future use.
Only suitable for domestic use
The Wartmann® dehydrator is exclusively intended for normal household use. In case of professional or
improper use, which is not in accordance with the instructions in the manual and in the event of self-
performed repair, the warranty will expire and Wartmann will refuse any responsibility for the resulting
damage.
Check electrical connections
Check if the voltage indicated on the Wartmann® dehydrator corresponds with the local mains voltage before
connecting the Wartmann® dehydrator. Connect the Wartmann® dehydrator only to earthed sockets. In case
the plug, power cord or the Wartmann® dehydrator itself is damaged, first have it repaired or replaced by a
certified service centre.
Avoid contact with water
The Wartmann® dehydrator contains electrical parts. Make sure that water can never end up on the power
cord inlet, control panel or on the electrical parts inside to prevent electric shock and/or damage to the
Wartmann® dehydrator.
Contains heating elements
Do not touch the heating element inside, it could be hot. Do not position the Wartmann® dehydrator near
flammable gasses or cleaning agents (such as methylated spirit).
Use original accessories
Always use the original Wartmann® accessories for this dehydrator. Accessories of other suppliers are not
supported.

FOOD PREPARATION
Food safety
Dehydrating at medium range temperatures does not kill pathogens. It is therefore important that any meat
or fish that is being dehydrated has been properly heated first, as to illuminate the risk of a pathogen
contamination.
Always work hygienic and use only fresh products that are properly cooled and stored until preparation.
Check if food is spoiled, before using it.
Meat should be heated to a temperature above 68 degrees Celsius for a longer period prior to dehydrating.
A piece with a thickness of 5 centimetre should be heated for at least 14 minutes at this temperature. Thicker
pieces require a longer time. Fisk should be heated until 93 degrees Celsius until flaky.
Food selection
We recommend to only use fresh and is possible seasonal food. Food that is spoiled may contaminate your
entire batch. Fat should be removed from meat as much as possible. Too much fat may cause unwanted
dripping.
Never use food that is marinated in alcohol to avoid the risk of a fire or explosion.
Food preparation
Food should be sliced to a thickness of 6 to 20 mm. Meats slices should ideally not be thicker than 5 mm.
Fruit can best be soaked in a citric liquid, such as lemon juice, for a few minutes to avoid the loss of colour.
Vegetables may require blanching. This will inhibit the enzymatic activity which causes loss of flavour and
colour fading. Cook the vegetables or place them in the microwave until they are done, but still a bit crispy.
Subsequently you immerse the vegetables in cold water, stopping the cooking process. Next, dry the
vegetables with, for instance, a clean towel.
All the food should be dry before placing them in the dehydrator. It should be placed on dehydration trays
without overlapping.
Dehydration temperatures
Dehydration temperatures may vary per depending on the moist level of the food. The time is depending on
the moist level and should be set until the food is fully dried. Typical temperatures are:
46 degrees Celsius
Spices and herbs
52 degrees Celsius
Vegetables and nuts
57 degrees Celsius
Fruit and pasta
68 degrees Celsius
Meat, poultry and fish
Food Storage
Vacuum packaging is a good method for storing food. Wartmann sells different type of vacuum devices,
vacuum bags and vacuum storage boxes. For a longer lifetime vacuum packed food is best stored cooled or
in a freezer.

should not burn when the Wartmann® dehydrator is powered off.
Cleaning
The stainless steel trays can be simply cleaned with warm water, dish washing liquid and a
brush after use. It is recommended to not put stainless steel in a dishwasher to avoid
premature corrosion. The inside of the Wartmann® dehydrator can be cleaned with a
detergent that is safe to use in ovens, such as an oven-cleaner. The outside of the Wartmann®
dehydrator may be cleaned with a microfiber cloth and a soft detergent, or a cleaner that is
suited for stainless steel. Always be careful around the power cord inlet and power switch.
Make sure no water can get inside the switch or on the power cord. To clean the power cord
it must first be removed from the wall socket.
Storing
We advise to clean the stainless steel trays, the dripping tray and the inside of the Wartmann®
dehydrator straight after use to avoid undesired bacteria growth. Do not leave wet stainless
steel trays in the Wartmann® dehydrator when it is not being used.
