It is possible to shrink the film by using the Tunnel. This series can be connected to the

conveyor belt at the outfeed of the sealing machines.

In order to achieve excellent packaging, the film is sealed at half the height of the product.

Raising (or lowering) the conveyor belts requires making adjustments to the tunnel blinds, as

it is essential to avoid losing heat during the shrinkage operation.

4.1 IDENTIFICATION DATA AND TECHNICAL DATA OF THE

MACHINE

Each machine is provided with a plate where it is easy to recover data which must be

communicated to the manufacturer in case of problems or when requesting spare parts etc.

(ref. 1-2-3-4). This plate also carries electrical technical data for installation of the machine (ref.a-b-c-d).

1 - Model

2 - Serial number

3 - Machine code

4 - Year of manufacture

a - Nominal voltage

b - Nominal frequency

c - Nominal power

d - Nominal current

ATTENTION! Before performing connections to the electrical mains, make sure that the power

supply voltage is compatible with that shown on the plate.

4.2 SHRINKING

Film shrinkage is achieved by the forced circulation of hot air around the package. The air is

heated by a heat-controlled resistor unit. If the sealing breaks during the shrinking it is possible

to increase the speed of the belt or to lower the temperature of the resistors by acting on the

tunnel's control panel.

4.3 REGULATION OF BAFFLES

The baffles A: reduce hot air flow below the product.

The baffles B: direct the hot air flow coming from the baffle A.

(Fig. 1) - The baffle A is closed and the air flow is conveyed below the product to be packed.If bubbles should form or the film tear at the bottom of the product in this situation, the air flow

coming from this direction must be reduced by opening the baffles A as shown in Fig. 2 and

Fig. 3.

6.1 GENERAL WARNINGS AND PRECAUTIONS

Cleaning and maintenance operations must be entrusted to expert personnel who know the

machine (mechanical maintenance technician and electrical maintenance technician, each

according to his own field of skills). In order to avoid the risk of interference by other operators

in the work zone, it is recommended to carefully mark maintenance in progress.

It is recommended to:

• Use only original spare parts

• Before carrying out any maintenance or lubrication operation, perform the "placing in

maintenance status procedure" as described in paragraph 6.2.• It is prohibited to carry out maintenance, lubrication or repairs when the machine is running

or powered electrically.

• After each intervention, put back any guards which were removed, placing the machine in

its initial status.

• It is forbidden to use matches, torches or open flames for lighting.

• Unauthorised personnel must remain at an appropriate distance from the machine.

• Always keep the area where maintenance is performed clean and dry. Always eliminate oil

stains.

• Before any type of intervention on electrical components, make sure the power supply line

has been disconnected.

• After all interventions on the electrical panel, put the guard back, securing it properly with

screws before restoring power and starting machine.

6.2 PLACE IN MAINTENANCE STATUS PROCEDURE

Before starting any required maintenance operation, if not requested otherwise, turn the

machine off and disconnect the plug from the mains. During all control operations, it is

compulsory to lock the master switch, as illustrated in the figure.

Before starting maintenance it is also recommended to place a sign on the control panel or onthe electrical power master switch with the following indication: ATTENTION! DO NOT TOUCH

- ASSISTANCE PERSONNEL AT WORK

All the operations indicated in this

chapter must be carried out by

qualified personnel and with

adequate personal protective

equipment for the operations being

6.5 LUBRICATION OF MECHANICAL PARTS

This paragraph provides information concerning lubricants which can be used to keep the

machine perfectly efficient. Should it be difficult to find these lubricants, you may use other

good quality lubricants with the same characteristics as those recommended. Do not mix

different types of lubricants.

List of mechanical parts which require lubrication:

1 - Oven conveyor belt chain

The specific lubricant recommended for the chains of the oven conveyor belt is Mobil

Pyrolube 830, a synthetic ester-based lubricant for parts operating at high temperatures (up

to 230°C). This oil can be applied with a brush, by drops or spraying (even with timers).

The fully synthetic base of Mobil Pyrolube 830 and the consequent low volatility

characteristics limit evaporation of the product at high temperatures and prevent the formation

of sludge and carbon residue. Using this oil instead of other mineral and synthetic oils has the

following advantages:

• Almost no carbon deposits

• No unpleasant odours

• Low consumption due to lubricating capacity of the product allowing you to limit the number

of applications.

• Longer duration of lubricated parts.

• Noise reduction

4 - Reduction gears

They require no oil change since they are the "long life" type.

6.6 REPLACING FLEXTRON MODULES

When replacing a FLEXTRON module, we recommend strictly following the indications

described below:

• Switch the machine off, disconnect power, interlock the general isolator and wait at least 5

minutes before operating.• Disassemble the casing of the electrical panel to access the modules of the FLEXTRON

boards.

• Press on the sides as shown in the figure to remove the connector 1.

• Take the connectors 2 off being careful to act on the body of the connector and not on the

cable.

• Remove the connectors 3 by loosening the screws 4.

• Act on the screws 5 to remove the FLEXTRON modules to be replaced.

After having replaced the damaged module, put all the connectors back on and, before

restoring the connection to the power supply, make sure that the protective casing of theelectrical panel has been put back in place.
