VI. INSTRUCTIONS FOR USE
THE OPERATOR HAS TO BE TRAINED AND KNOW THE CONTENTS OF THIS
MANUAL
CLOSING OF PREFORMED BAGS AFTER FILLING
• Put the luminuous switch (n. 2 pict. 1 ) in “I” position. This one will switch on and the heat sealer will be
ready for the use.
• Adjust the sealing time, through the potentiometer (n. 9 pict 2), setting the right value according to the bags to
seal (see SUGGESTED SEALING TIME).
• Introduce the mouth of the bag between the bars to let a free edge, quite mm. 20, over the seal.
• Through the pivoted plain knob (n° 6 pict. 2), exercise a little pressure on the moving bar (n° 7 pict. 2 ), the
bar will close for the set sealing time and the sealing led (n° 2 pict. 4 ) will switch on ,showing the sealing
phase.
• As the sealing led (n ° 6 pict. 4) switch off, the cooling led (n°1 pict. 4) automatically will switch on and the
bars will kept in pressure the time necessary to obtain a perfect seal.
• As this cooling led switch off, the bars will automatically open to allow to the operator to take out the bag
sealed.

THE SEALING TIME HAS TO BE SET ACCORDING TO THE SPECIFICATIONS OF THE
BAG TO BE SEALED AND THE DESIRED OUTPUT.
A comparative electronic control limits the heating of the resistance to avoid any overheating in case of fast
sealing sequence.
WE SUGGEST YOU TO KEEP AN OUPUT OF 6/7 SEALS PER MINUTE.

SUGGESTED SEALING TIME
The DN 350 S is equipped through a electronic matching system that limits the sealing wire heating during its
use to avoid high heating storing up in case of rapid sealings sequence. Than the set time about the a) case is
suitable only for the first and/or second sealing.
a) first sealing or long sealing intervals
FLAT BAGS: potentiometer knob (n° 3 pict 4) in position 8/10 (*)
BAGS WITH GUSSET: potentiometer knob (n° 3 pict 4) in position 8/10 (*)
b) sealing made in rapid sequence
FLAT BAGS: potentiometer knob (n° 3 pict 4) in position 8/10 (*)
BAGS WITH GUSSET: potentiometer knob (n° 3 pict 4) in position 8/10 (*)
(*) depending by the real supply voltage line
after the automatic re-opening of the sealing jaw, at the end of the cycle , we suggest to wait
for 4 or 5 sec. before doing the next seal, in order to get a max max output of 6/7 per
minute

SAFETY ELECTRONIC CONTROL
In case of fault of the heating electronic control, the RED WARNING led (n° 4 pict. 4) will switch on and, in
the same time, the power supply of the resistance will be interrupted .
In this case stop the production and get in touch with your Dealer Service Department.
PRODUCTION OF POUCHES FROM THE SPOOL
• The spool can be cut both form right or left and viceversa.
Then take the cutter knob (n°4 pict 2) to one the two edges to allow the spool in-feed.
• Place the spool on the rolls (n° 2 pict. 2) and introduce the spool edge through the slit, as shown in
the pict. 5. till it will exit between the sealing bars (n° 7 and 8 pict. 2), to get the desired pouch length you
would produce.
• Through the pivoted plain knob (n° 6 pict. 2), start the sealing cycle
• While the bars are closed, during the sealing and the cooling phases, let flow on the side the cutter
knob (n° 4 pict. 2) to cut the spool.
• At the end of the cycle, the bars will open and the bag is ready to be filled.
• Repeat the in-feed operation, to prepare the next pouch

VII. MAINTENANCE
IT CAN BE EFFECTUATED ONLY BY TRAINED TECHNICIANS
ALWAYS UNPLUG THE POWER SUPPLY CABLE (n° 1 pict. 1)
1) machine opening procedure :
To access top the inner components it is needed to remove the cover (n° pict. 2) of the machine.
Do as follows :
a) extract the cutter knob (n° 4 pict. 2) in vertical direction
b) unscrew the two rear screws (n° 4 pict. 1) and the two lower screws (n° 2 pict. 3)
c) Remove the cover (n° 3 pict. 2) of the pivoted plain , after to have unscrewed its fixing
screws (n° 5 pict. 2)
PAY ATTENTION TO THE CUTTER BLADE (n° 4 pict. 3)
d) unthread in front , the cover from the machine
2) glass-PTFE protective cloth (n. 24 pict. 7)
The protective cloth could be damaged for normal use , for too long sealing time, or for the casual introduction
of any tools between the bars.
For the replacement proceed as follows:
a) set the pivoted plain (n°3 pict. 6) on the max opening using the adjustment opening bars ball
grip (n°1 pict. 3) located underneath the base of the machine, loosen its locknut.
b) unscrew and remove the two screws (n° 1 pict. 6)
c) extract the lower sealing bar (n° 8 pict. 2) from the machine
To work more softly , unplug the two power supply cable (n° 30 pict. 7) from the tails of the bar.
d) replace the old cloth with a new one. The original spare clothes have adhesive bands to facilitate the
application
It is very important that the bags do not make any crumples
e) fit back the sealing bar proceeding on the contrary.
f) before tighten the two screws (n. 1 pict. 6 ), be sure that the bar perfectly leans on its own
stands (n° 2 pict. 6)

do not loosen the two adjustement stands (n° 2 pict. 6)
g) restore the opening of the pivoted plain to its work position : act through the ball grip (n°1 pict. 3) till
to get the “h” gap = 8 mm. as shown in the picture n° 6

2 : lower sealing bar adjustment stand 4 : electromagnet
3) lower sealing bar resistance replacement
The resistance could be deformed or interrupted because of a casual introduction of chirurgical tools or any other
solid objects between the bars.
For the replacement, follow the upper instructions till the point c) removing the protective cloth too. Then :
a) unscrew the two screws (n° 28 pict 7)
b) remove the damaged resistance keeping care that you do not loose the two sockets (n° 27 pict.7) and
the two compensation springs (n° 29 pict. 7)
c) check the sub-resistance band (n° 26 pict. 7) and , if damaged, replace it.
d) Fit back all proceeding on the contrary.
the resistance must be fit well stretched during its fitting through the screws (n° 28 pict 7).
do not act the machine without the sealing wire connect to the timer board, to avoid damage to the
probe NTC located on the timer board

XV. HOW TO DISCARD THE MACHINE
According to the DIRECTIVE 2002/96/CE rules this symbol indicates that the device,
when its work-life is ended, must not be discarded as a urban waste.
It can be given to a suitable discharging centers of the electronics and electric equipments
or delivered to the dealer if you purchase an equivalent device.
The device owner is responsible for the delivery in to the discharging centers.
To get more informations about the discharging system, we suggest you to contact your
local discharging waste service.
The right discharging of the disuse devices avoids such a negative consequences to the ambience and the human
health.
