IMPORTANT
This instruction manual contains information for the use and maintenance of your vacuum device.
Read this instruction manual carefully before using the vacuum 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.
Check electrical connections
Check if the voltage indicated on the vacuum device conforms with the local mains voltage before
connecting the vacuum device. 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.
Prevent the vacuum device from coming into contact with water
The vacuum device contains electrical parts and heating elements. Never rinse the vacuum device
under the tap and do not immerse the vacuum device in water. Make sure that no water ever enters
the vacuum device to prevent electrical shock and/or damage to the vacuum device.
Contains heating elements
Do not touch the seal wire, it could be hot. Do not position the vacuum device near flammable gasses
or cleaning agents (such as methylated spirit).
Use original accessories
This manual applies to the use of Wartmann® vacuum bags. For vacuum bags from other suppliers,
other instructions may apply.

FOOD SAFETY
Vacuum-packaging
When vacuum-packaging food in vacuum-storage boxes, most of the surrounding air is extracted whilst
the inflow of fresh air is being prevented. This way the storage life of food is lengthened.
Vacuum-packaging helps to prevent freezer burn, which is the dehydration of the surface layer of the
food. This is characterised by white or brown-red discolouration of the food.
Vacuum-packaging contributes to the preservation of the taste and the overall quality of the food. It
slows the growth of aerobic micro-organisms that could cause:
Mould. As mould won’t grow in environments with little oxygen, the vacuum-packaging will
strongly reduce the risk of moulding.
Fermentation. Fermentation can be noticed by the odour or taste of the food. Fermentation
requires water and sugar and will develop at room temperature. Fermentation can also develop
when air is lacking. In order to slow the yeast growth items should be cooled, only at deep-freezing
temperature, this growth will come to a halt.
Bacteria. Bacterial growth can often be recognised by a nasty smell, discolouration and a soft or
slimy layer. Under specific circumstances, clostridium botulinum, which causes botulism, can grow
without air. This is rare, but also extremely dangerous. You can neither smell nor taste it.
The vacuum-packaging is no replacement for cooling or deep-freezing. Perishable foods that require
cooling or freezing, must still be kept in the refrigerator or freezer.
Deep-freezing
In order to safely preserve foods, it must be kept at low temperatures. The growth of micro-organisms
is strongly reduced at temperatures of 4°C and below. At a temperature of -17°C, growth will nearly
come to a full stop. This does however not kill the micro-organisms.
If you wish to store your vacuum packed food long-term, then always place it in the freezer.
Verify
Always check if food is spoiled, before consuming it. You must realise that vacuum-packaging cannot
undo spoilage. Vacuum-packaging only ensures that the quality of food is retained longer. How much
longer you can preserve the food, depends on different factors, such as the quality of the food at the
time of packaging. We advise to only package fresh food and mention the date of packaging on the
package.

PREPARATIONS
Before you can start vacuum-packaging vegetables, they need 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.
Cruciferous vegetables, such as broccoli, sprouts, cabbage, cauliflower, kale and turnips produce
carbon dioxide during preservation. Therefore, you can only store these vegetables in the freezer.

OVERVIEW OF THE VACUUM DEVICE
Control buttons
1. Seal button with indicator light
Use this button to only seal a vacuum bag. There will be no vacuum. This button lights up when the
sealing is in progress.
2. Vacuum button with light indicator
Use this button to vacuum and seal a vacuum bag. The vacuum bag will automatically be sealed once
the air has been sucked out the bag. The button lights up when the vacuuming is in progress.
Pressing this button once more will cancel an ongoing vacuum- or sealing process.
3. Release button
Press this button after every vacuum cycle to unlock the lid (The release button releases the vacuum
in the vacuum chamber so that the lid can be easily opened).

USING THE VACUUM DEVICE
Unpacking the vacuum device and preparations for first use
Take the vacuum device out of the box and remove all packaging materials. Place the vacuum device
on a horizontal surface in a location where the vacuum device cannot tip over, even when passing.
Switching on the vacuum device
Insert the plug of the vacuum device into a wall socket. The vacuum device is now ready for use.
Seal and vacuum a product in a vacuum bag
Choose a vacuum bag of suitable width and place your product in the bag, leaving approximately 4 cm
open at the top. Open the lid of the vacuum device and place the open end of the bag over the sealing
strip with the open end inside the vacuum chamber.
Close the lid and press it lightly whilst shortly pressing the vacuum button. The vacuum indicator will
light up. After approximately 3 seconds you may let go of the lid; it will stay in its closed position. The
vacuum bag shrinks whilst the inner air is being removed; after a while the vacuum indicator goes out
and the seal indicator lights up. Wait until the seal indicator goes out.
Now press the release button, open the lid and take your vacuum bag out. Carefully inspect the seal.
A proper sealing will be transparent over the entire length. If the sealing is mottled, white or milky or
even crumpled, then it is not properly sealed. In this case, cut off the sealing and create a new sealing
in accordance with the abovementioned steps.
Wait at least 45 seconds before you vacuum or seal a second bag.
Seal a product in a bag (without a vacuum)
Choose a bag of suitable width and place your product in the bag. Open the lid of the vacuum device
and place the open end of the bag over the sealing strip, but not into the vacuum chamber!
Close the lid and press it lightly whilst shortly pressing the seal button. The seal indicator will light up.
After approximately 3 seconds you may let go of the lid; it will stay in its closed position. Wait until the
seal indicator goes out.
Now press the release button, open the lid and take your vacuum bag out. Carefully inspect the seal.
A proper sealing will be transparent over the entire length. If the sealing is mottled, white or milky or
even crumpled, then it is not properly sealed. In this case, cut off the sealing and create a new sealing
in accordance with the abovementioned steps.
Wait at least 45 seconds before you seal a second bag.

Tips for packaging
Pack the food as freshly as possible. By means of vacuum-packaging, the freshness of the food can be
retained up to five times longer, compared with food that is stored under regular circumstances.
Delicate and moist food, as well as food of which the shape should be retained, must first be frozen.
Food such as meat, berries and bread can be frozen up to 24 hours before freezer burn starts. As soon
as the food is solid, you can deep-freeze it.
If you choose to package meat without freezing it first, then place a folded paper towel between the
meat and the top of the bag. This will absorb moisture.
Firstly, freeze liquid food, such as soups, stews and casseroles in, for instance, an oven dish. As soon
as they are frozen, they are ready for vacuum-packaging, marking and storage in the freezer.
Cover sharp points and edges of products such as bones, pasta and rice first, using a paper towel. This
reduces the risk of the vacuum bag being punctured.
Vacuum bags are suitable for the microwave and are hot water resistant. You can re-use vacuum bags,
unless they have been used to store fish or fat food. We recommend that you do not re-use vacuum
bags that have been cooked or been in the microwave.
Vegetables should be blanched first before vacuum-packaging is done. Mushrooms and garlic cannot
be vacuum-packed.
