2. CHECK POINT RECEIVING DELIVERY OF THE MAHCINE
2-1 The packing state
*It must be checked before opening the packing box.
* Is there any damage on the packing box? If so, the buyer may not accept the
machine or must open the box with agreement of the delivery person and must
take some photos before opening the box and keep those. This is needed to judge
the responsibility of the delivery company. The above is not applied in the case
that the machine is delivered directly by JSPACK™.
2-2 The contents inside of the packing box
* Check the contents inside the packing box after checking the packing state.
* Are there any missing parts or any damage? If so, take some photos for that and
keep those.
2-3 For any defect
* For any problem, please follow the above procedure and contact JSPACK. JSPACK
will respond it ASAP.

3. CAUTION FOR USE
3-1 Caution for safety
1) In case of emergency, please pull off the electric cord. The machine has the
noise filter and the fuse to cut off any irregular electric shock. Nevertheless, if
there is any emergency such as breaking out of a fire on the Teflon tape, please
cut off electric inflow from the machine.
2) The electricity specified in the manual must be used and use of multi tap is
not recommended. Especially, Home-use multi tap could be cause of overheat,
short machine life, quality degradation and a fire. If the user has no choice but to
use multi tap, please consult with electric expert.
3) In case of exchanging any part of the machine, the electric cord must be
pulled off. And, to prevent any malfunction or accident, it is prohibited for the
user to use any machine parts different from the specification stipulated by the
manufacturer.
4) It is prohibited for the user to re-build the machine and its parts without
permission from the manufacturer
5) It is prohibited for anything except for vacuum bag to be inserted between
sealing bars.
* There is electric flow between sealing bars so that inserting metal material
could lead to electric shock.
(This machine uses earth wire to reduce the risk of safety accident.)
* Especially, Long time use of machine could accumulate heat on heat wire so
that if the finger is caught between the sealing bars it could result in burn as
well as hurting.
6) If the N.F.B turns off automatically, the cause must be checked and solved
before turning the N.F.B on again.(Refer to 17-3)
7) The user must avoid installing the machine in the place full of dust, high
temperature or high humidity. The temperature of work place suitable for this
machine is 0°C ~ 40°C; 30°and the machine must avoid any direct or continuous
air from air conditioner located within 10 m from the machine.
8) For any wrong work, press the STOP button or EMERGENCY button. Then, all
work is stopped and the nozzle moves back and the upper sealing bar go up.
9) Please check up whether there is any damage on the Teflon sheet, Teflon
tape and sealing rubber, compression sponge, the between sealing bars and
heat wire holder before use of the machine. Any damage on these parts could
result in short circuit around heat wire. Or, it could lead to wire’s exposure to air
during sealing resulting in overheat.

10) This machine must be used by any adult person who is trained well and can
use it without problem.
11) When you move this product, you have to move carefully and safety.
3-2 How to make a good sealing
1) Please check up whether there is any damage on the Teflon sheet, Teflon
tape sealing bars and heat wire. If there is any damage, exchange it with new
one.
2) Please check up whether the sealing bars are clean. Any alien substance on
there can make bad sealing result and can give damage to Teflon sheet, Teflon
tape and Heat wire
3) Before mass operation, please find out the proper vacuum, sealing and
cooling time through enough sealing tests
4) Please set sealing time as short as possible in the range that sealing is
possible. Too long sealing time can give damage to the Teflon sheet, Teflon tape,
heat wire, etc., which makes bad sealing result and causes low productivity and
high electric consumption
5) Please set enough cooling time 3 times or more than sealing time. Long
cooling time makes clean sealing result and avoids accumulation of heat on heat
wire leading to longer machine life.
6) Long and continuous sealing could raise the temperature of sealing bar. In
that case, please reset sealing time shorter and cooling time longer
7) In the case of use of pure PE bag or vacuum bag with thick PE film, set
cooling time 5 times more than sealing time. For pure PE bag with 200μ, about
sec. of cooling time is needed.
4. DEFINITION OF THE MACHINE
4-1 Definition
This machine is a nozzle type vacuum and gas flushing packing machine and there
are electric motor driven model and air driven model. It carries out vacuum and gas
flushing inside a vacuum bag and seals it. The application includes protection of
packed goods from decomposition, oxidation and discoloration.
4-2 Basic function
Press MODE button on the controller. Then, the user can select a mode among the
below.
1) S Mode: Sealing
2) V Mode: Vacuum ->Sealing

9

(5) Set and use among vacuum 4 times gas flushing 3 times sealing 1 time
cooling 1 time as the user likes. Set any unnecessary work at 0 then it is
skipped.
5. INSTALLATION OF THE MACHINE
5-1 Image
5-2 Installation of the machine
1) Basic setting
Install the machine horizontally in any place with no humidity, no external shock,
no vibration and good ventilation.

2) For electric motor driven model
(1) Connect the electric cord to the noise filter of the machine and provide 1ph
220Vand connect any earth wire. (This machine uses the electric cord with
ground connection. But, if the electric outlet connected to the machine has
no ground connection, the user must connect any earth wire to the body of
machine)
(2) Connect gas line at proper gas pressure using the pressure controller.
* The proper gas pressure is among 1~4.9 kg/㎠. Set gas flushing quantity
and time according to the vacuum bag size.
* Don’t set gas pressure over 5 kg/㎠.
(3) Connect the foot switch.
3) For air driven model
(1) Connect the electric cord to the noise filter of the machine in the same way
for electric motor driven model.
(2) About 400NI/m of compressed air is needed to be connected.
* the external diameter of the air hose connected to the machine is 8∅. The
required air pressure is 5~6.5 kg/㎠. 7kg/㎠and more could give damage to
the pneumatic parts while 4.5 kg/㎠and less could lead to malfunction of the
machine. (To increase the pressure of the compressed air, pull up the head of
air regulator and turns right (clockwise). To decrease the pressure of the
compressed air, pull up the head of air regulator and turns left
(counterclockwise). Set it at about 6 kg/㎠and press the head of air regulator
to lock it)
* Remove any liquid from the compressed air for clean compressed air supply.
Any compressed air with a lot of liquid can give damage to the machine.
Remove any liquid from the air regulator by pressing the pin on the bottom
of the air regulator.
(3) Connect the gas line to the machine in the same way for electric motor
driven model.
(4) Connect the foot switch.
4) For vertical model
(1) Select electricity type according to the ordered machine type among 1ph
220V, 3ph 220V, 3ph 380V.
(2) Some vertical model might need any special distribution box or circuit
breaker.
(3) This machine selects 3ph 5 lines (4 lines + earth line) in 3ph 380V for safety.
