1.1. Introduction

You have bought a machine with outstanding features and performance and we thank You very much for Your confidence in choosing it.

The MINIPACK System is the only one of its kind and has achieved worldwide succes

with more than 60000 units operating in the field of packaging and wrapping.It is handy, low-priced and protected by patents at home and abroad.The technological concept underling its design, as well as the components and materials used in the manufacturing and testing process are the best assurance of proper operation and long-lasting liability.

1.2. Performances of packaging machine

Thanks to its particular operating circuit, it can be used both as a sealing and shrinking machine or as a plain sealing machine (sealing

only) .In this case it is possible to pack the object in a soft bag without shrinkwrapping.

Technical grade or food grade films with thickness in the range of 15-50 micron can be used. These products are manufactured and distributed by MINIPACK Torre S.p.A. The film used in centerfolded execution can be micropunched or not when running through the micropunches of machine itself. The machine can carry out up to 650 packages/hour.

1.3. Machine identification

In every communication with the manufacturer, always mention the model and the serial number specified on the plate on the rear part of the machine.

1.4. Weight and dimensions of packed machine

a = mm 1415 b = mm 955 c = mm 830 Weight = Kg 192

1.5. Weight and dimensions of machine

a = mm 1570 b = mm 800 c = mm 500 d = mm 1450 Weight = Kg 152

Chapter 2. Installation of the machine

2.1. Transport and positioning

It is recommended to handle with great care during transport and positioning!

Cut the strap with scissors (make sure you protect your eyes by wearing glasses) and withdraw the cardboard.

Take away the box (A) which contains

the carriage. Take away the bobbin support (C). Take away the roller way (B)

Unscrew the 4 fastening screws of the

allet, putting the 4 plates back inside

the machine.

Assembly the carriage.

Lift the machine and position it on the carriage, paying attention that the 4 foots are properly inserted in their housings.

To place the roll support (13) follow the instructions below:

Remove the adhesive tape (A) fixing the guides trolley. Place the roll support (13) on the proper guides.

Stride over the blocking device (B) through a working tool (for example a screw driver).

Position the roller way, coupling it to the conveyor belt.

2.2. Environmental conditions

Place the machine in a suitable environment free from humidity, gases, explosives,

combustible materials.

Woring environmental conditions:

• Temperature from + 5°C to + 40°C

• Relative humidity from 30% to 90%, without condensation

Machine safety factor = IP20 The aerial noise made by the machine is lower than 70dB

2.3. Electrical connections

OBSERVE HEALTH AND SAFETY REGULATIONS!

Before executing the electrical connections, make sur that the mains voltage matches the ono on the plate on the rear of machine and that the earthing contact complies with the safety rules in force. In case of doubts about the mains voltage, contact the local public supply company.

GROUNDING OF THE UNIT IS OBLIGATORY!

Chapter 3. Machine adjustment and preparation

3.1. Control of direction of rotation

Partially extract (about 20 cm) the switch box after having removed the four fastening screws (A).

Press the push button of contactor KM3 manually and check that the fan rotates clockwise. Otherwise invert two of the three phases of the electrical plug.

Before starting the machine operation check the right direction of rotation following these instructions:

Rotate the general selection switch

on 1-position

Partially extract (about 20 cm) the

switch box after having removed the four fastening screws (A).

Press the push button of contactor KM3 manually and check that the fan rotates clockwise. Otherwise invert two of the three

phases of the electrical plug.

3.1. Control of direction of rotation

Push the emergency button (8) to get the machine into START position. Close the switch block again and unlock the emergency button (8) by turning it

towards right.

N.B.: THE CONTROL OF DIRECTION OF ROTATION SHOULD BE CARRIED OUT

EACH TIME YOU CHANGE THE ELECTRICAL PLUG.

Push the emergency button (8)

to get the machine into START position.

Close the switch block again and unlock the emergency button (8) by turning it towards right.

N.B.: THE CONTROL OF DIRECTION OF ROTATION SHOULD BE CARRIED OUT EACH TIME YOU CHANGE THE ELECTRICAL PLUG.

3.2. Adjustment

ELECTRONIC BOARD FEATURES

The machine is equipped with 6 selectionable programs:

Program nr. Program features

P4 - P5 - P6

Each program is composed by 6 variables which can be modified (in case it is not possible to set one of them, such a variable will obviously not appear on the display) :

Variable Field Field features

1. Sealing

2. Fan delay after sealing

3. Shrinking

4. Belt advancing time

5. Automatic cycle pause time

6. Temperature

The machine is equipped with a piece counter to show on display (N) the number of sealings. Such a value can be put to zero at any time through reset button (M).

PHASE NR. 1 = SWITCHING THE MACHINE ON

Turn the main switch (A) into pos. 1. Before using the machine, wait until the adjusting temperature is reached. This is signalled by the extinction of the warning light (F). The display (H) turns on and the number of the currently selected program will appear.

PHASE NR. 2 = PROGRAMS SELECTION

Push button (G) to select the number of the program.

PHASE NR. 3 = VARIABLES PROGRAMMING

Through button (I) it is possible to look through the variables of the selected program, while through buttons (L) the memorized values can be modified. Once the value has been set, push the S button and then release it; the LED of the next function will light up. Set the value of the variables as previously described. To validate modifications, presso button (I) until the number of the program appears on the display. The fan delay time after sealing can be modified; there is not a LED indicating this variable which is shown with an “r” on the left display, while the right one shows the time which has been set. At the end of all variables to be adjusted, the display will show the code of the program just chosen (for example P1). N.B.: In case during programming the FC limit switch is being pressed, the unit quits the scheduling, the selected program is executed and the display shows the number of the program.

PHASE NR. 4 = PERFORMANCE

Once all adjustments have been made, the machine is ready to start working.

In case of “ANOMALY” the display will show as follows:
