THEORY OF OPERATION
This vacuum drawer is solely for vacuuming and sealing food in
suitable vacuum bags and containers. These can then be stored
or processed further (for example, low-temperature cooking or
sous vide cooking).
1The user places the food to be sealed in a vacuum bag, and
then places the bagged food into the vacuum chamber. The
user sets the vacuum level and sealing time using the
buttons on the control panel. With the lid closed, the user
touches to begin the vacuum seal procedure.
2The button turns on the vacuum pump. The vacuum
pump connects to a valve block, consisting of a ventilation
valve (which vents the vacuum chamber to atmosphere) and
a sealing bar valve (which causes the vacuum to move the
vacuum lifting cylinders connected to the sealing bar). Both
of these valves are closed during pump-down, so air is
removed from the vacuum chamber.
3When the pressure sensor on the control board measures
that the specified vacuum level has been reached inside the
vacuum chamber, the control board opens the sealing bar
valve. The pistons in the vacuum lifting cylinders extend
through the vacuum, raising and energizing the sealing bar
to heat-seal the vacuum bag.
4When the specified sealing time has passed, the control
board opens the ventilation valve. Air enters the vacuum
chamber, restoring it to ambient air pressure.
5The return to ambient air pressure causes the vacuum lifting
cylinders to lower. This opens the safety switch, interrupting
the heating of the sealing bar. The user can then open the
lid and remove the food.

Vacuum Pump, Valve Block, and Vacuum Inlet
The vacuum pump and the valve block (consisting of the
sealing bar valve and ventilation valve) are responsible for
creating and controlling vacuum in the vacuum chamber.
Sealing Bar, Vacuum Lifting Cylinders, and Transformer
During the sealing phase, the pistons in the vacuum lifting
cylinders extend through the vacuum, raising the sealing bar
into contact with the vacuum bag. The upward movement of the
vacuum lifting cylinders closes a safety switch on the underside
of one of the vacuum lifting cylinders, allowing current to flow
from the transformer through the sealing bar (a thermal
protection switch prevents the transformer from overheating).
The sealing bar, pressing the vacuum bag against the
counterpressure bar in the lid, heats up. The heat melts the
plastic of the vacuum bag, creating an air-tight seal.
Control Board
The control board is responsible for controlling the individual
components.

Control Panel
The control panel communicates the user's settings to the
control board. The control panel also shows the user any error
messages or tips (for example, recommending a
dehumidification cycle). It also contains a reed switch that
senses the magnet in the lid.
Lid and Gasket
The glass lid is laminated and double-glazed. The lid and its
gasket hermetically seal the vacuum chamber. The view into the
vacuum chamber during this process allows the user to
intervene (for example, sealing sooner if bubbles start to form).

VACUUM SEAL DRAWER SAFETY
CAUTION
The vacuum chamber and glass lid become distorted
under vacuum. There must be at least a one-
centimeter gap between vessels or screw-top jars
and the appliance lid. Otherwise, the glass can
become damaged and the lid can shatter, causing
personal injury.
CAUTION
The sealing bar in the vacuum chamber gets very
hot. The sealing seam of the vacuum bag also heats
up during the sealing process. Do not touch the hot
sealing bar or other accessible parts, or burns could
result.
CONTROLS
Opening the drawer reveals the control panel, which features
touch controls and LED indicators.
Each control illuminates to indicate that it is active. For vacuum
level, auxiliary vacuum level, and sealing time, three LEDs
above each control indicate the level of vacuum or sealing.
Vacuum and Seal
Vacuum Level: Indicated by one, two, or three illuminated
dashes above .
Seal Level: Indicated by one, two, or three illuminated
dashes above .
CAUTION
Selecting an improper seal level can damage the
sealing bar. Wait at least two minutes between
sealing cycles. All contents must be at or below room
temperature prior to the sealing operation.
1Place food in the vacuum bag.
2Open the lid, and place the bag into the chamber.
3Place the open end of the bag under the bag clip. For
smaller bags, insert the bag support to support the bag
while sealing.
4Touch .
5Touch multiple times to select the desired vacuum level.
6Touch multiple times to select the desired seal level.
7Press down on the lid, and touch to initiate the vacuum
process.
An audible signal indicates the process is complete.
8Open the lid, and remove the food.
Vacuum Only
CAUTION
This process is not intended for canning or making
jam. All contents should be at or below room
temperature.
Jars less than 7.6 cm tall with screw-top lids can be vacuumed
to remove air. Once the vacuum seal is broken, the contents
should be placed in the refrigerator.
1Place the lid on the jar, then lightly tighten the ring and
place in the chamber.
IMPORTANT NOTE: Do not over-tighten the lid. Air must be able
to escape.
2Touch .
3Touch multiple times to select the desired vacuum level.
4Touch multiple times until no LED indicators are
illuminated.
5Touch , then press down on the lid to initiate the vacuum
process.
An audible signal indicates the process is complete.
6Open the lid, and remove the food or jar.
Seal Only
Bags can be sealed without creating a vacuum. The vacuum will
turn on and off briefly during the "seal only" operation to seat
the lid and make sure the sealing bar is in contact with the bag.
TIP: For best results, fill the vacuum seal bags less than half full
when sealing fragile foods.
The original food packaging can be sealed using the "seal only"
function. Adjust the seal level according to the thickness of the
bag. Use seal level 1 for bags thinner than Wolf vacuum seal
bags.
1Place food in the vacuum bag.

process.
An audible signal indicates the process is complete.
8Open the lid, and remove the food.
Auxiliary Attachment
The included auxiliary attachment allows vacuum sealing of
wine bottles and other rigid containers.

opposite ends of the vacuum hose.
2Place the unit adapter over the vacuum inlet in the vacuum
chamber.
3Place a bottle stopper in the wine bottle.
4Place the bottle adapter over the stopper.
5Touch multiple times to select the desired vacuum level.
Use level 1 for all bottles and rigid containers unless
otherwise specified for the container.
6Touch to start the vacuum process.
TIP: Touching causes the and lights to turn off. To
resume normal operation, select a vacuum setting.
An audible signal indicates the process is complete.
Pump Dehumidification Cycle
If the specified vacuum level is not achieved within the required
time (about two minutes) 10 times, the appliance advises the
user to do a pump dehumidification cycle. The light
illuminates. From this point, the user can run another 10
operating cycles until the appliance quits, forcing the user to
carry out a pump dehumidification cycle.
Without the alarm, the pump dehumidification cycle can only be
started by service personnel using the service menu on the
control panel.
Run a Pump Dehumidification Cycle
Moisture can build up in the vacuum pump oil, which could
damage the unit. Run a pump dehumidification cycle when
appears on the display.
Touch .
The pump cycles for approximately 10 minutes. Once
complete, the unit turns off.
Allow the unit to cool for 1 hour before starting another cycle.
Enter the Service Menu
1With the appliance in standby mode, touch and hold and
at the same time, and hold both buttons for about two
seconds until the appliance beeps.
2While holding and , touch , and hold all three buttons
for about one second until the appliance beeps.
3Release the three buttons within two seconds of the beep.
The Service menu is available, and the following buttons
illuminate:
▪Evacuation time:
