The model V-300 and V-300-10D vacuum sealer is provided with a vacuum pump for reducing the air in
the pouch prior to sealing. Compared with conventional sealers, the additional function or removing air
from the package can increase the life of food and prevent oxifation of metal parts, as well as protecting
parts against scratching each other in the pouch.
In cases where high protection is required, it is recommended that a deoxidizer or dessicant should be
used in conjunction with the vacuum seal. Preservation of foods sometimes requires refrigeration, gas
flushing, etc. Please check food regulations for the proper method.
Remenber, laminated material should be used when vacuum sealing is necessary. Before carrying out
your packaing work, please perform a number of tests to decide the best sealing condition for your
application.
※Vacuum pump capacity is measured before it is assembled.
※Ultimate pressure 0 torr equal 0 Pa.

1The impulse sealer is a machine which sends strong electric current quickly to the thin ribbon heater,
which presses against the film and instantly heat seals the package. Though this machine yields
superior quality sealing, it is not compatible with films thicker than that indicated in the diagram
below, sponge-like sheets, and materials which are not able to withstand high heat.
2Vacuum packaging requires a laminated pouch made with high-barrier property materials such as
nylon-based films. Using films with low gas barrier properties will allow air to seep into the pouch
over time, negating the effectiveness of a vacuum seal.
3Film thickness limits for the V-300 series are described below. The machine cannot seal bags which
are thicker than that indicated. The machine may malfunction if you try to exceed the limits of the
machine.

6 Operating precautions
For safety operation
Warning In an emergency, unplug the power cord immediately
This sealer incorporates a number of safety devices and is carefully
designed to prevent fires or other malfunctions. However, should all of
the safety devices fail simultaneously, there is a possibility of the teflon
catching fire due to a failure of the heating circuit's tripping mechanism
that results in the heating element overheating. Should smoke or fire
appear from the teflon, immediately release the foot pedal or turn OFF
the power.
Warning Confirm proper electric power source
Make sure power source has the specified voltage and electric power as
explained in “1 Specification” of this manual. DO NOT use an extension
cord, as the machine may malfunction due to voltage drop or may result
in fire. Machine will malfunction if connected to anything other than the
specified voltage.
Insert the electric power plug fully into the wall outlet.
Warning Do not use for packaging liquids
Do not splash water on the machine or use machine for packaging liquids
since machine is not waterproof. There is a danger of electrocution or
malfunction of the machine.
Warning Do not insert any metal objects into the sealing area
Please do not place any metal objects into the sealing area during
operation. This could cause electrocution.
Warning When replacing parts, unplug the power plug
Maintenance of the machine is important. Parts should be replaced in
accordance with the operating instructions. There is a risk of danger if
the parts are not replaced properly. Before replacing parts, unplug the
machine from the power source and replace parts referring to “Replacing
the routine maintenance parts” thoroughly.
Warning Do not use parts other than those specified
When replacing parts, always use only specified parts sold through
Van der Stahl Scientific. We are not responsible for malfunctions
caused by the use of unspecified parts.
V-300 Series Operating Instructions Ver1.01E

Warning Do not modify the machine
Modification of the FA series or the use of unspecified parts may not only
lead to damage of the machine, but there is also a risk of danger to the
operator. Please do not tamper with the machine. Accidents or damage
caused by modification by the customer is the sole responsibility of the
customer.
Caution Do not use in the following places
Do not operate machine in the following places since there is a danger of
malfunction:
1Dusty locations.
2Locations not within normal temperatures.
3Locations with high humidity.
Warning If the power switch automatically turns to the OFF position
If after 3 seconds heating is not complete after it has been initiated, the
power switch will automatically turn to the OFF position. There is a
possibility of malfunction of the machine. Do not operate the machine
until the cause of the shut down is ascertained and the problem has been
addressed.
Caution Do not place hands in the sealing area
1With prolonged use, the sealing area will retain heat and become
hot. If you place your fingers in this area, there is a possibility of
burns.
2Do not place hands between the seal jaws (pressure lever and
seal fram).
Caution Use the machine properly
Read “Proper use of the sealer” in this manual carefully and operate
sealer correctly. Accidents or damage caused by misuse of the machine
not in accordance with the operating instructions are the sole
responsibility of the customer.
Caution Run test trials first before beginning operation
Achieving a superior seal with an impulse sealer is determined by
heating / cooling / pressure strength. Depending on the type of film being
used and the contents of the bag, heating / cooling / pressure strength
conditions may drastically differ. Find the optimum sealing conditions
by conducting seal tests before proceeding.
V-300 Series Operating Instructions Ver1.01E

For smooth operation
●To achieve a strong seal
Proper sealing pressure is important in achieving a strong seal. Sealing
pressure for FA series can be adjusted by the power to depress the pedal.
Apply the optimum pressure when sealing.
●When operating machine for extended periods of time
The machine's temperature will rise upon prolonged use of the machine.
As the temperature of the machine rises, the condition of the seal will
change. Thus, heating time should be shortened and cooling time should
be lengthened accordingly.
●Dust in the sealing area
Dust will prevent attainment of a smooth seal. It could also cause
damage to heating element and/or other routine maintenance parts.
Before using the machine, clean the sealing area.
●Heating time should be set at a minimum
Set sealer so that an acceptable seal is completed in the least amount of
heating time. Excessively long heating times (increasing the heat setting
unnecessarily) will damage the teflon, glass tape and other consumables,
as well as result in heating element breakage. This will lead to decreased
work productivity and unnecessary power consumption.
●Allow sufficient cooling time
Cooling time is important when using an impulse sealer. After the film
is heated, the film must cool with the frame and pressure lever in the
closed position. Take the cooling time 1.5 times longer than the
heating time. For the detail, please refer to “8-7 Setting the sealing
condition with the control unit”.
●When the Teflon, silicone rubber becomes damaged
The Teflon, silicone rubber will start to wear with use. Once they are
damaged, it will be difficult to achieve smooth and strong seals.
