2.2 PRODUCT DESCRIPTION
The adhesive hot melt units described in this manual are used together with PREO
hoses and guns for the composition of a hot-melt application system, as illustrated
in figure 2:
Figure 2
The applicator (1) melts the hot-melt adhesive and keeps it at the desired
temperature.
Once the temperature has been reached, the melted adhesive is pumped through
the heated hoses (2) and is distributed onto the product by means of automatic
and/or manual guns (3).
The temperature control and adhesive distribution programme (if present) are
controlled by latest generation microprocessors.
Depending on the configurations installed, optional accessories may also be
present, making the entire system fully functional.
2.3 METHODS OF USE
PREO hot-melt adhesive applicators have been specifically designed and
manufactured for the following uses:
•melting and application of adhesives and thermoplastic materials with a
viscosity of up to 70,000 Cps.
•melting and application of adhesives and thermoplastic materials with
working temperature of below 230°C (450°F).
•use in environments not subject to risk of explosion
Only use the PREO hot-melt adhesive applicators for the purposes for which they
were designed.

3.2 INSTALLATION REQUIREMENTS
Before installing the applicator, make sure that the necessary environmental
conditions and services are in place.
Figure 6 illustrates the minimum area necessary for correct installation and ideal
system operation.
Figure 6
You should also take the following additional factors into consideration before
proceeding with installation.
•Install the system in environments with a temperature between –5°C and
+50°C.
•Install the system well away from areas subject to strong draughts or
repeated changes in temperature.
•Install the system in such a way that the operator is able to access all the
controls in complete safety.
•Avoid positioning the system on surfaces subject to strong vibrations.
•Always avoid contact with water, inasmuch as the applicators are not
watertight.
3.3 CHECKING YOUR PURCHASE
Before installation, make sure that the machine has not been damaged during
transport or by storage conditions.
Also make sure that all the optionals ordered and all the equipment supplied as
standard are included in the packaging.
The hot-melt unit is supplied by the factory with an installation kit containing
components that the client should install on the applicator.
The client will need additional materials to complete the installation.
3.4 REMOVING THE PACKAGING
Before installation, remove the applicator from the relative packaging.
Hoses, guns and any accessories are supplied loose from the applicator and
packaged in bags or boxes inside the packaging.

3.6 POWER SUPPLY CONNECTION
Make sure that the lines are able to power the machine correctly, in compliance
with safety regulations. Earth the entire machine correctly. In order to make the
connection, you will need a suitable power cable (not supplied with the applicator).
Refer to figure 8 for correct power supply connection.

3.7 PNEUMATIC SUPPLY CONNECTION
Connect a mains air supply to the air filter opening, as illustrated in figure 10, and
set the applicator working air pressure using the pressure regulator, turning it in a
clockwise direction.
Figure 10
We recommend using dehumidified compressed air.
The recommended pressure is 6 bar.
3.8 HEATED HOSE CONNECTION
Wire and plumb in the hoses to the respective connectors, as illustrated in figure
11, bearing the following aspects in mind:

•When installing the hoses, avoid abrasions or twisting the could damage the
cover and avoid bending them with a radius of under 150 mm.
•Avoid installing the hoses in contact with cold surfaces that could prevent
the adhesive from being correctly distributed or prevent it from being
dispensed.
•Wire the hose to the applicator, bearing in mind that the number with
which the hose is identified by the microprocessor depends on the electrical
connection with the connector and not on the manifold position.
•Do not tighten or unscrew the hoses when the system is cold, so as not to
damage the fittings and cause glue leaks.
•Begin screwing the manifold onto the fitting manually, without using a
spanner, so as to ensure it is in the correct position.
•Then tighten the hose fitting with a 19 mm spanner when the system is
heated up, so as not to break the thread.
3.9 GUN CONNECTION
Connect the revolving hose fitting to the gun fitting using two spanners in order to
tighten it correctly. Wire the gun connector to the hose connector as illustrated in
figure 12.
Figure 12
Pay specific attention to the following aspects:
•Thermally isolate the gun from the support using the insulator provided.
•Never use a gun which is missing any of its components. The gun body
contains live components.
•Never touch the guns during operation and never point them at anyone.
Risk of burns.
•Assemble the gun as near as possible to the substratum (5-50 mm), leaving
the necessary space for carrying out maintenance work or replacing its
components.
