IMPORTANT
This instruction manual contains information for the use and maintenance of your sous vide device.
Read this instruction manual carefully before using the sous vide device and keep it for possible later
consultation.
Only suitable for domestic purposes
This device is exclusively intended for common household use. In case of (semi)-professional or
incorrect use, usage not in accordance with the instructions in the manual, or self-performed repairs,
the warranty expires and Wartmann® will decline any responsibility for any damage caused by this.
Not suited for Children
The sous vide device operates on electricity and comes partly in contact with water. The device is not
suited for installation or operation by children.
Check electrical connections
Check if the voltage indicated on the sous vide device conforms to the local mains voltage before
connecting the vacuum device. Connect the sous vide device only to a grounded socket. In case the
plug, power cord or the vacuum device itself is damaged repairs must be carried out first, or the
relevant part should be replaced, by a qualified service centre.
Careful with water
The sous vide device contains electrical parts and a heating element. Never rinse the sous vide device
under the tap and do not fully immerse the sous vide device in water. Make sure that no water ever
enters the part above the Max indication on the device to prevent electrical shock and/or damage to
the sous vide device.
We advise to only top-up the water level with the device not plugged into the wall socket.
If the part above the Max indication, the control panel, has been in contact with water then
immediately remove the power cord from the socket. Place the sous vide device in a vertical position
so that no water can run in the control panel. Let the sous vide device dry properly.
Contains heating elements
Do not touch the heating element, it may be hot. Be careful when moving the water container. The
water can be hot during and after sous vide cooking. Use utensils to take your products out of the hot
water to avoid the risk of burn. Let the water container cool off before you move the container.
Use original accessories
This manual assumes the optional use of Wartmann® vacuum equipment and vacuum bags. For
products of other suppliers other instructions may be applicable. The Wartmann® vacuum bags are
suited for temperatures up to 100 degrees Celsius.

PREPARATIONS
For sous vide cooking you’ll require some additional tools beside the sous vide device.
Water container
You will need a water container, such as a polycarbonate container, a high pan or even a bucket. The
container should be capable to withstand temperatures of up to 100 degrees (boiling water) for an
extensive period of time. The recommended depth of the container is between 15 and 19 centimetre.
The volume of the container should not exceed 30 litres (measured from bottom to water line). The
smaller the container, the quicker the water will heat up.
Vacuum bags
You will require bags to watertight seal your food. The bags should be able to withstand temperatures
of up to 100 degrees Celsius and must be safe for food. For hygienic purposes we recommend to always
use new bags and to avoid the reuse of bags. Always check sealed vacuum bags for leakage before use.
Vacuum device
For an optimal result we advise the use of a vacuum device. A vacuum device will remove the excessive
air from the vacuum bag and seal it properly. The thermal conductivity is much better with all the air
removed and the change that your bag will start to float in water is a lot less compared to bags
containing some air.

USING THE SOUS VIDE DEVICE
Attach the sous vide device
Select a proper water container with a minimal depth of 15 centimetre. Place the water container on
a stable, horizontal surface where it can’t fall off, not even when somebody passes by. Place the device
in the container and attach it firmly with the spring clamp to one of the sites of the container. Check
that the power cord is long enough to reach a power socket, but do not yet plug in the device.
Fill the water container
Fill the water container with cold water but take care that the water level never passes the Max
indicator on the sous vide device. Note that the water level will raise when you add your bags with
food. You may have to carefully shake the device if there are indications that there is air in the device

Switch on the sous vide device
Check that no one can stumble over the power cord. If necessary use an extension cord with grounded
terminals. Plug the power cord into a grounded power socket. The control panel may shortly light up.
Now switch on the device by pressing the On/Off button for 5 seconds. The control panel will light up
and the device is now ready for programming.
Change the temperature unit
By default the temperature is shown in degrees Celsius. Pressing the On/Off and Select buttons
simultaneously for two seconds will change the temperature unit to Fahrenheit. Pressing both buttons
again for 2 seconds will change the temperature unit back to Celsius.
Set the temperature
The required temperature can easily be set by turning the rotary wheel. Turn the wheel
upwards for a higher temperature, turn the wheel downwards for a lower temperature.
The temperature can be set between 0 and 95 degrees Celsius.
Set the duration
Press the Select button shortly to set the required duration. The hours of the set duration on
the control panel will start to blink.
Now turn the rotary wheel to set the required hours. Press the Select button again to set the
minutes. The minutes will start to blink. Now turn the rotary wheel again to set the required
minutes. Finally press the Select button again to confirm the set duration. The set duration
will shortly blink to confirm that the duration has been set.
Your sous vide device has now been programmed.
Start the pre-heating
By pressing shortly on the On/Off button the device will start to pre-heat the water. You will
hear that the pump is running and notice that the water circulates.
During the pre-heating the actual temperature will gradually increase until the set temperature has
been reached. When the set temperature has been reached you will hear a peep tone. This tone will
repeat every 3 seconds.
Place your vacuum bags
Carefully check that your products are properly sealed, then place your bags in the water container.
Start the cooking programme
Press the Select button for 2 seconds. You will hear one long peep and the repeating peep tone
will stop. The cooking programme has started.
Once the cooking programme is started the control panel will show the actual duration. After one
minute the duration will jump to 00:01 hours.

- 8 -
Your sous vide cooking is ready
When the required duration is reached you will hear a peep tone that repeats every 3 seconds. Your
ingredients are now ready. The water temperature will stay at the set temperature and the duration
will continue until you actually press the On/Off button.
Take the vacuum bags out of the water
Press the On/Off button. The peep tone will stop and the vacuum bags can now be taken out of the
water container for further processing. We advise to always use some plyers for taking the bags out of
the water container. This to avoid that you burn yourself on the hot water.
Change time or temperature during operation
During a preparation you can change the set temperature by simply turning the rotary wheel. The
displayed duration will then automatically come to a halt. You will have to set the duration again to
the newly required time.
A damaged vacuum bag
Should a vacuum bag get damaged during the cooking then food may leak out of the bag and
contaminate the water. If food gets into the sous vide device it may block the water circulation.
Damaged vacuum bags should therefore be removed from the water container. Refresh the water and
if necessary clean the sous device.

- 9 -
AFTER USE
Power down
Press at least 5 seconds on the On/Off button to switch the device off. The control panel will
go dark. You may hear a low noise indicating that the device is still cooling off. Wait at least
three minutes and then remove the plug from the wall socket.
Detach
Detach the device from the water container by opening the spring clamp and carefully lift the sous vide
device out of the water container. Place the sous vide device vertically and let it stand until it is fully
dry.
Let the water in the water container cool down enough before you move and empty the water
container.
Store
After the sous vide device is cooled off and dry it can be stored away. Store the device preferably is a
standing position.
Aging
Do not leave the sous vide device in water any longer than necessary to avoid premature aging of the
sous vide device.

MAINTENANCE
Proper use and periodic maintenance of the sous vide device is necessary to guarantee the expected
life-time and a proper operation. Please stick to the following recommendations:
Never place a hot sous vide device in cold water. It is advised to first let the sous vide device cool
down until its temperature matches the water temperature. For the same reason it is also not
advised to place a cold sous vide device in hot water.
Refresh the water before every preparation; do not repeatedly use the same water.
After the device has been used and cleaned it is best stored standing; a wet device should never
be stored laying down.
Descale the sous vide device regularly. Recommended is to descale the device after every 20 times
of use, or after 100 operating hours.
If you notice any damages to the inner components then the device should be sent to a service centre
for repair. Do not repair the device yourself; this may be dangerous and will void your warranty.

- 11 -
DESCALING
Why descaling
Tap water contains minerals such as Calcium and Magnesium. Heating this water results in scale
deposits on the thermostat and the heating element of the sous vide machine. As a result the heater
may not work efficiently and the water pump may get blocked. The sous vide machine should therefore
be descaled regularly. The frequency with which you need descaling depends on the hardness of your
tap water. We recommend to descale the sous vide device after every 100 hours, or after every 20
times, of use.
Tools
To descale the sous vide device you will need a water container with a minimum depth of 15
centimetre and a suited descaling agent. You may use food save (white) vinegar or citric acid as a
descaling agent.
Cleaning Procedure
Attach the sous vide device with the clamp to the water container. Fill the water container with water
just up to the Max indication, leaving enough space to add the descaling agent. Add the descaling
agent. For vinegar, use 5 grams of vinegar per 10 litres of water. Wear protective clothing when
working with chemicals, use rubber gloves and safety glasses. Rinse immediately with clean water if
undiluted chemicals get into your eyes; if necessary contact your doctor.
Plug the power cord into the power socket and switch the device on. Set the duration at 3 hours and
the temperature at 80℃(176 F). Press Start. After approximately 3 to 4 hours you will hear a high tone.
Press Stop, switch the device off and remove the power cord from the power socket.
Check the device for any signs of remaining scale. Repeat the above cleaning cycle if scale is still
present; if necessary use a higher concentration of descaling agent.
If there are no more signs of scale rinse the device with clean water. Place it in a vertical position and
let it dry. Once the device is fully dry you can store it away.
