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 sh 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 rst before
vacuum-packaging is done. Mushrooms and
garlic cannot be vacuum-packed.
Vacuum a product in a vacuum canister
The Wartmann
®
vacuum device can also be
used with a vacuum canister. The vacuum is
controlled by the button on the lid of the
vacuum canister. By setting the button to close,
you shut off the air supply, securing the vacuum.
Setting the button to open, air will ow into the
vacuum box, after which you can take off
the box lid.
Check rst that the gasket in the lid is dust-free and
that it contains no food residues. Also check if the
vacuum box is dry. Place the product to be stored
in the vacuum canister. Leave a little room on top of
the food, so that air can easily ow out. Place the
lid on the vacuum canister and set the button of the
vacuum canister to “vacuum”.
Connect the one side of the vacuum hose to the
nipple of the vacuum canister, and the other side to
the nipple of the Wartmann
®
vacuum device. The
nipple is in the vacuum chamber on the right hand
side and is only visible with the lid open.
Briey press the Canister button and subsequently
also press the vacuum box lid lightly for 3-5
seconds. The Canister button is located on the right-
hand site next to the vacuum chamber.
The vacuum device will stop automatically as
soon as the vacuum has been reached. After this,
turn the button on the vacuum box lid to “lock”.
Subsequently disconnect the vacuum hose from
the lid nipple.
If you want to interrupt the vacuum process, then
briey press the Canister button again. In order
to undo the vacuum entirely, you should turn the
vacuum box lid to open, and briey lift the lid from
the vacuum box.
Keep the vacuum box in your fridge. To open the
vacuum box, you turn the button on the vacuum
box lid to “open”.
Tips for using vacuum boxes
Use only storage boxes that are suitable for vacuum
storage. Ordinary storage boxes may implode
when creating a vacuum in these boxes.
Warm foods must cool off before they are vacuum-
packed. Cool any liquids in the fridge before you
vacuum-pack them.
Vacuum boxes can be kept in the freezer. The
recommended lowest temperature at which
a vacuum box can be stored is -18 C. At
temperatures lower than that, the vacuum boxes will
suffer too high an under-pressure. At temperatures
exceeding 100C, there is a chance that the
vacuum boxes will deform or melt.
From the moment you start the vacuum process,
lightly press the vacuum box lid for three to
ve seconds.
Do not place the vacuum box lid in the dishwasher
or microwave, but clean it manually. The vacuum
box (without a lid) is suitable for the dishwasher
