VI. INSTRUCTIONS FOR USE

THE OPERATOR HAS TO BE TRAINED AND KNOW THE CONTENTS OF THIS

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.

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

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

ALWAYS UNPLUG THE POWER SUPPLY CABLE (n° 1 pict. 1)

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)

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:

b) unscrew and remove the two screws (n° 1 pict. 6) c) extract the lower sealing bar (n° 8 pict. 2) from the machine

PAY ATTENTION TO THE CUTTER BLADE (n° 4 pict. 3)

d) unthread in front , the cover from the machine

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.

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

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)

It is very important that the bags do not make any crumples

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

1 : lower sealing bar fixing screws 3 : pivoted plain 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).
