2 Instructions for use
2.1 Installation
The equipment can be employed in any working environment that is dry without excessive dust.
Place the sealer on a steady work surface, leaving a large enough space in front of it for the bags to
position.
Be sure, the heat sealer is at least 30 mm from the back wall in order to allow a right release of the heat
produced inside and laterally it has the needed space for an easy bag infeed.
Finally, take enough space on the ground useful to act the start cycle foot pedal (see picture).
2.2 Electrical wiring
Check the main luminous switch (n°2 pict. a) is in the “O” position (OFF).
Introduce the plug (n° 3 pict. a) of the supply cable into the machine socket (n° 4 pict. a), always before
connecting the supply cable into a single phase socket.
Plug the supply cable into the single phase earthed power source provided with a magneto thermal switch
mounted in the circuit, in accordance to the law rules, after checking that the data on the identification
plate correspond to the ones of the power net.
Plug the foot pedal JACK into the corresponding plug (n°3 pict. I) located on the side of the machine.
If the JACK plug is not connected to its socket, once switch on the machine, the
automatic cycle starts.

10
2.3 Switching on the machine
Switch on the heat sealer through the main GREEN luminous switch (n°2 pict. a) on position “1” (ON).
The display (n°1 pict. d) of the thermo regulator (n°2 pict. d) will light on, beginning the AUTOTEST phase
that is marked out by the flashing number “1.5” (*) for a few seconds.
(*): Depending by the software release.
In case of mistake messages (see par. 3.3), don’t use the machine and get in touch with
Audion Elektro.
The thermo regulator display (n°1 pict. d) shows the actual temperature value of the welding jaws that are
reaching the set temperature.
Set the cycle times according to the bags to be sealed (see chapter 3).
When the SET temperature will be reached, the heat sealer is ready to be used.
To get the temperature stabilization, we suggest to wait for few minutes before employing the
machine.
